For further information on features and adjustment of the seat, see the manufacturer's Service and Operation Manual included with the vehicle. Seat Adjustment WARNING! Do not adjust the driver's seat while the vehicle is moving. The seat could move suddenly and unexpectedly and can cause the driver to lose control of the vehicle.
SEATS AND RESTRAINTS Safety Restraint Belts much worse when riders are unbelted. Always fasten your seat belt and be sure anyone riding with you does the same. Therefore, read the following instructions and always observe user warnings pertaining to safety belts. WARNING! Do not drive vehicle without your seat belt and your riders belts fastened. Riding without a safety belt properly fastened can lead to death or personal injury in an emergency.
SEATS AND RESTRAINTS 1 above the speedometer/tachometer (see "Seat Belt, Fasten" on page 3-23). Lap/Shoulder Belt The combination lap-shoulder belt is equipped with a locking mechanism. The system adjusts automatically to a person's size and movements as long as the pull on the belt is slow. Hard braking or a collision locks the belt. The belt will also lock when driving up or down a steep hill or in a sharp curve. 5.
SEATS AND RESTRAINTS If the belt is locked, lean the body back to remove any tension in the belt. After releasing the belt, allow the belt to retract completely by guiding the belt tongue until the belt comes to a stop.
SEATS AND RESTRAINTS 1 WARNING! Proper seat belt adjustment and use is important to maximize occupant safety. Failure to wear or adjust the safety belt properly may result in death or personal injury. Tether Belts WARNING! This vehicle may have an external tether belt installed with a seat, instead of the internal tethering device. Tether belts are designed to restrain the seat in the event of a sudden stop or an accident. Internal tether belts do not require adjustment.
SEATS AND RESTRAINTS To adjust an external tether belt Komfort-Latch® Feature • Your vehicle includes a feature designed to eliminate cinching and provide improved safety and comfort. Cinching is the condition where a belt becomes continually tighter around you during a rough, bouncy ride. The need for this feature increases with rough road conditions, particularly over long distances. Make sure that the tether belt is attached to the cab floor and seat frame.
SEATS AND RESTRAINTS 1 WARNING! Do not set the Komfort Latch with too much slack. Too much slack may reduce the effectiveness of the seat belt. Failure to comply may result in death or personal injury. During Pregnancy Pregnant women should always wear combination lap/shoulder belts. The lap belt portion must be worn snugly and as low as possible across the pelvis. To avoid pressure on the abdomen, the belt must never pass over the waist.
SEATS AND RESTRAINTS Belt Damage and Repair Safety Restraint Tips Damaged belts in the cab must be replaced. Belts that have been stretched, cut, or worn out may not protect you in an accident. • Do not wear a belt over rigid or breakable objects in or on your clothing, such as eye glasses, pens, keys, etc., as these may cause injury in an accident. • Any authorized person sleeping in your vehicle while it is moving should use the bunk restraint.
SEATS AND RESTRAINTS 1 • Keep seat belt and bunk restraint buckles free of any obstruction that may prevent secure locking. • Damaged or worn belts in the cab or sleeper, subjected to excessive stretch forces from normal wear, must be replaced. They may not protect you if you have an accident. • Any belts or restraints that have been subjected to an accident should be inspected for any loose (attaching) hardware or damaged buckles.

WHAT TO DO IF... Stop Engine Lamp Turns On WARNING! 2 If the air pressure falls below 60 psi (414 kPa) the spring brakes may stop the vehicle abruptly, which could cause an accident resulting in death or personal injury. Observe the red warning lamps on the gauges. If one comes on, do not continue to drive the vehicle until it has been properly repaired or serviced. If the light and alarm do not turn off at startup, do not try to drive the vehicle until the problem is found and fixed.
WHAT TO DO IF... 6. 7. Wait a few minutes to allow oil to drain into the engine oil pan, and then check the oil level. (See Oil Level Check on page 5-100, for details on checking oil level.) Add oil if necessary. If the problem persists, contact an authorized dealer as soon as possible. CAUTION Continuing to operate your vehicle with insufficient oil pressure may cause severe engine damage or cause an accident which may result in equipment or property damage.
WHAT TO DO IF... off. This allows the engine to cool gradually and uniformly. 7. 2 If overheating came from severe operating conditions, the temperature should have cooled by this time. If it has not, stop the engine and let it cool before checking to see if the coolant is low. For further information on engine temperature and operating engines properly, see the Engine Operation and Maintenance Manual and Starting & Operating the Vehicle on page 4-5.
WHAT TO DO IF... Fuse Inspection and Replacement CAUTION Never patch fuses with tin foil or wire. This may cause serious damage elsewhere in the electrical circuit, and it may cause a fire. CAUTION If a circuit keeps blowing fuses, have the electrical system inspected for a short circuit or overload by an authorized dealer as soon as possible. Failure to do so could cause serious damage to the electrical system and/or vehicle.
JUMP STARTING VEHICLES JUMP STARTING VEHICLES 2 Introduction Jump starting a vehicle is not a recommended practice due to the various battery installations and electrical options. However, if your battery is discharged (dead), you may be able to start it by using energy from a good battery in another vehicle. This is termed jump starting. Be sure to follow the precautions and instructions below. WARNING! Batteries contain acid that can burn and gasses that can explode.
JUMP STARTING VEHICLES To Jump Start Your Vehicle Preparing the vehicles: CAUTION WARNING! When jump starting using a battery booster, it is best to jump start with an equivalently powered vehicle. Verify that the booster battery has the same volt and CCA specifications as the dead battery before attempting to jump start. Failure to comply may cause an explosion resulting in death, personal injury, equipment or property damage.
JUMP STARTING VEHICLES 7. If either vehicle is equipped with battery disconnects ensure they are in the "OFF" position prior to connecting the two vehicles. Connect the batteries: 1. 2 Attach one end of a jumper cable to the positive (+) terminal of the discharged (dead) battery. This will have a large red + or P on the battery case, post, or clamp. 2. Attach the other end of the same cable to the positive (+) terminal of the good (booster) battery. 3.
JUMP STARTING VEHICLES Remove jumper cables: WARNING! When disconnecting jumper cables, make sure they do not get caught in any moving parts in the engine compartment. Failure to comply may result in death, personal injury, equipment or property damage. 2 Reverse the above procedure exactly when removing the jumper cables. With engine running, disconnect jumper cables from both vehicles in the exact reverse order, making sure to first remove the negative cable from the vehicle with the discharged battery.
VEHICLE RECOVERY AND SPRING BRAKES VEHICLE RECOVERY AND SPRING BRAKES 2 Vehicle Recovery Guidelines Your vehicle is equipped with removable Recovery Hitches, designed for short distance recovery purposes only. Use only the provided hitches, according the following instructions. When using this connection, do not transport your vehicle over long distances. (If your vehicle does not have the proper hitches, contact your dealer.) the lubricant in the top front of the drive axle will drain to the rear.
VEHICLE RECOVERY AND SPRING BRAKES Recovery Procedure 1. 1 (03/17) Review and understand all the cautions and warnings of this section, see Vehicle Recovery Guidelines on page 2-12. 2. Install the recovery hitches, see Recovery Hitch Installation on page 2-15. 3. Disconnect the drive axle shafts and cover the open hubs.
VEHICLE RECOVERY AND SPRING BRAKES WARNING! Before towing a vehicle, test your air brakes to ensure that you have properly connected and inspected the recovery vehicle’s brake system. Failure to do so could lead to a loss of vehicle control which may result in an accident involving death or personal injury. 2 7. Follow state/provincial and local laws that apply to vehicles in tow. 8. Do not tow vehicles at speeds in excess of 55 mph (90 km/h).
VEHICLE RECOVERY AND SPRING BRAKES If your vehicle is not equipped with the proper recovery hitch assembly, contact an authorized dealer to obtain the proper equipment. Recovery Hitch Installation Driver Controlled Main Differential Use the following procedure to install the Vehicle Recovery Hitches. See Recovery Hitch Assembly illustration for part identification. Follow these steps to lock a driver-controlled main differential. 1.
VEHICLE RECOVERY AND SPRING BRAKES 2 Driver Controlled Main Differential Lock 1 2 1. Air Line (remove to install Caging Bolt) Caging Bolt (in storage location) CAUTION CAUTION Failure to lift the driving wheels off the ground or remove the driveline and axle shafts before towing the vehicle could seriously damage your vehicle. All lubricating and clutch application oil pressure is provided by an engine-driven pump, which does not work when the engine is stopped.
VEHICLE RECOVERY AND SPRING BRAKES This action will lock the differential by pushing a piston into a "lock" position. CAUTION Failure to install the caging bolt when towing vehicles with driver-control main differential lock can result in damage by failing to lock internal components in position. CAUTION CAUTION A recovered vehicle will have no operational brake system. Additionally, the rear axle spring brakes will probably be applied. Connect recovery rigging only to hitches intended for that purpose.
VEHICLE RECOVERY AND SPRING BRAKES Recovery Hitch Capacities 2 The maximum rated loads for vehicle recovery varies depending on the direction or angle of pull. These capacities are listed in the table below and are for the two hitches working together, simultaneously. Hitch Capacities DIRECTION OF PULL MAXIMUM CAPACITY (Lb) * Directly Forward 80,000 Directly Vertical or Horizontally to the Side 14,600 45º in any Direction 20,000 * Both hitches pulled simultaneously.
VEHICLE RECOVERY AND SPRING BRAKES Recovery Rigging • To connect to the vehicle, follow the suggested rigging methods below. Never loop a single chain or cable through both hitches (3). • Use a spreader or equalizer bar to distribute the load on both hitches (1). • Use a double chain or cable setup that distributes the load equally to both hitches. See 1 or 2 in Recovery Rigging illustration. (03/17) • cable no closer than 6 ft. from the vehicle (2).
VEHICLE RECOVERY AND SPRING BRAKES Returning Vehicle to Service 2 You will have to add lubricant to prevent damage after your vehicle has been towed. 1. Into the pinion cage, add 1 pint (.47 liter) of lubricant or into the interaxle differential, add 2 pints (.94 liter) of approved lubricant. 2. After adding the specified type and amount of lubricant, drive the vehicle. It should be unloaded. Drive 1 to 2 miles (1.5 to 3 km) at a speed lower than 25 mph (40 km/h).
VEHICLE RECOVERY AND SPRING BRAKES WARNING! Do not operate a vehicle when the spring brakes have been manually released. Driving a vehicle after its spring brakes are manually released is extremely dangerous. The brakes may not function. Failure to comply may result in death, personal injury, equipment or property damage. WARNING! Always secure the vehicle with wheel chocks, chains, or other safe means to prevent rolling before manually releasing the spring brakes.
VEHICLE RECOVERY AND SPRING BRAKES 6. With a wrench, turn the release stud assembly nut until the compression spring is 90-95 percent caged. While doing this, check to make sure the push rod (adapter push rod or service push rod) is retracting. Do not over-torque the release stud assembly. (S-Cam type maximum: 50 lb-ft, Wedge type maximum: 30 lb-ft). The spring brake is now mechanically released.
VEHICLE RECOVERY AND SPRING BRAKES • Be sure that transmission is fully engaged in gear before releasing the clutch pedal (manual only). • Do not shift into reverse while the vehicle is moving. • If the vehicle needs to be recovered from being stuck, do not permit the vehicle to be towed for long distances without removing the driveshaft. Tire Chains If you need tire chains, install them on both sides of the driving axle.

STARTING & OPERATING STARTING & OPERATING Introduction Since each vehicle is custom-equipped, all engine operation instructions in this manual are general. You will want to consult the manual for your engine to find out details about your specific engine’s needs. You may need to use a slightly different procedure from the one outlined here. Below are instructions for both normal-temperature starting and cold-weather starting.
STARTING & OPERATING manual for the right pressure for your engine. If the oil pressure doesn’t rise within a few seconds, stop the engine. Find out what is wrong before restarting the engine. 7. Slowly engage (release) the clutch after the engine has started. 8. Wait for the oil pressure gauge to reach normal operating pressure before operating the vehicle or idling faster than 1000 rpm.
STARTING & OPERATING Engine Warm-up CAUTION Always unplug heater before starting the engine. Damage to the cooling system could occur if the heater is not turned OFF (unplugged). Depending on engine make, when the temperature falls below -10° F (-24° C), the block heater is required. • • Use a solution of half ethylene glycol antifreeze and half water for best heater performance. Do not exceed 65 percent concentration of antifreeze, as a shortened heater life will result.
STARTING & OPERATING WARNING! CAUTION NOTE Exhaust fumes from the engine contain carbon monoxide, a colorless and odorless gas. A poorly maintained, damaged, or corroded exhaust system can allow carbon monoxide to enter the cab or sleeper. Failure to properly maintain your vehicle could cause carbon monoxide to enter the cab and cause death or personal injury.
STARTING & OPERATING NOTE • Do not stay in the vehicle with the engine running or idling for more than 10 minutes with the vehicle’s Heater and A/C ventilation system in RECIRC or at LOW FAN SPEED. Even with the ventilation system On, running the engine while parked or stopped for prolonged periods of time is not recommended. • If other vehicles are parked next to you idling, move your vehicle or do not stay in your vehicle for prolonged periods of time.
STARTING & OPERATING Transmission In cold weather (below 32° F (0° C), you may find shifting sluggish when you first start up. Transmission warm-up is especially important at this time, but it is always a good idea to warm-up your transmission before starting out on the road. To warm-up the transmission, follow these procedures. 4 a. Put the main transmission in gear. b. Put the auxiliary transmission in Neutral. This will allow the transmission countershaft to turn, agitating the oil and warming it.
OPERATING THE ENGINE OPERATING THE ENGINE 5. Stationary PTO Operation Cancelling Cruise Control The cruise control buttons for this vehicle may be used to control the engine rpm when the vehicle is stationary and the operator wants to use the PTO on the engine. Use the cruise control options in the same manner as with the vehicle in motion, but instead of setting vehicle speed, the engine speed (RPM) is set instead.
OPERATING THE ENGINE 4 Winterfronts WARNING! NOTE Do not work on or near the fan with the engine running. Anyone near the engine fan when it turns on could be injured. If it is set at MANUAL, the fan will turn on any time the ignition key switch is turned to the ON position. In AUTO, it could engage suddenly without warning. Before turning on the ignition or switching from AUTO to MANUAL, be sure no workers are near the fan.
OPERATING THE ENGINE Engine Control Display NOTE The winterfront is designed to minimize the temperature differences across the radiator and reduce the possibility of cooling module damage. Aftermarket winterfronts may not provide the proper airflow distribution and could cause cooling module damage. Your vehicle may come with an optional Engine and Driver Information Display. This instrument records information on engine diagnostics, scheduled maintenance, driving conditions, and general trip information.
OPERATING THE TRANSMISSION OPERATING THE TRANSMISSION Introduction 4 Your Medium Duty is equipped with either a manual or automatic transmission with special features and gearing to meet your particular needs. It is important for you, the driver, to understand how your particular transmission is operated. To do this, you have two sources of information: this Operator's Manual and the transmission manufacturer's Driver/Operator's Instruction Manual.
OPERATING THE TRANSMISSION Transmission Warm–Up Putting the Vehicle in Motion In cold weather [below 32°F (0°C)], you may find shifting sluggish when you first start up. Transmission warm-up is especially important at this time, but it is always a good idea to warm your transmission oil before starting out on the road. After making sure the vehicle's oil and air pressure are correct and all other parts and systems are in proper working condition: 1.
OPERATING THE TRANSMISSION opposite direction during clutch engagement. If you need to start up on an incline, apply your service brakes before you release the parking brake. Then release your service brakes as you engage the clutch and apply throttle. where maximum torque and power are obtained. For further information, see More Driving Tips and Techniques on page 4-62.
OPERATING THE TRANSMISSION Clutch Brake and Travel (9–, 10–, and 11–Speed Transmissions only) These transmissions utilize a clutch brake, rather than synchronizers. The clutch brake works by stopping all of the gears in the transmission, allowing you to easily shift into first gear or reverse without grinding gears. The total stroke of the clutch pedal is about 10 inches. The first part is the release stroke: the part that fully releases the clutch. The last inch engages the clutch brake.
OPERATING THE TRANSMISSION ° 4. 5. 4 Downshifts: press accelerator, increase engine and gear speed to the rpm required in the lower gear. Now quickly press the pedal to disengage the clutch and move the gear shift lever to the next gear speed position. Release the pedal to engage the clutch. "Riding" the Clutch The clutch is not a footrest. Do not drive with your foot resting on the clutch pedal. It will allow your clutch to slip, causing excessive heat and wear—damage could result.
OPERATING THE TRANSMISSION Putting the Vehicle in Motion CAUTION After making sure the vehicle's oil and air pressure are correct and all other parts and systems are in proper working condition: 1. Fully depress the clutch pedal (for manual transmission) until the clutch brake makes contact. a. b. (03/17) The total stroke of the clutch pedal is about 6 inches (152 mm). The first ½ inch (13 mm) is free travel.
OPERATING THE TRANSMISSION More Driving Tips and Techniques on page 4-62. Shifting Gears in a New Vehicle Clutch Brake and Travel Shift carefully in a new vehicle. The transmission may be a little stiff at first. Avoid gear clashing, by closely following these procedures. The clutch brake is used for stopping transmission gears, allowing you to easily shift into first gear or reverse without grinding gears. Approximately the last ½ inch (13 mm) of clutch pedal travel activates the clutch brake.
OPERATING THE TRANSMISSION During Normal Driving Double Clutching If you want to shift directly into any gear other than first or reverse, depress the clutch pedal only far enough to release the clutch. Fully depressing the pedal applies the clutch brake and could cause gear hang-up. Whether you are upshifting or down shifting, it is best to double clutch.
OPERATING THE TRANSMISSION Automatic and Automated Transmissions An automatic or automated transmission makes shifting much easier. It remains important to completely understand how to operate the transmission to optimize its efficiency. Please read the manual for your automatic or automated transmission included with your vehicle. 4 For automated transmissions, there is no "park" position. So you will need to apply the parking brake before leaving the cab.
OPERATING THE TRANSMISSION Auxiliary Transmission More Transmission Tips Riding the Clutch If you have an auxiliary transmission, see your transmission manufacturer’s manual for its proper operation. The clutch is not a footrest. Do not drive with your foot resting on the clutch pedal. It will allow your clutch to slip, causing excessive heat and wear, damage could result.
OPERATING THE BRAKE SYSTEM OPERATING THE BRAKE SYSTEM Introduction This vehicle’s brake system functions with the use of compressed air generated from the engine’s air compressor. The compressed air is stored in various air tanks to ensure that air pressure is available whenever the driver needs it. 4 Compressed air is delivered to the brake system through the valve at the brake pedal and is controlled with various valves and braking circuits.
OPERATING THE BRAKE SYSTEM WARNING! WARNING! WARNING! The Anti-Lock Brake System is a critical vehicle safety system. For the safety of you and others around you, have the vehicle submitted for periodic preventive maintenance checks as well as having any suspected problems immediately checked by an authorized dealer. Failure to properly maintain your brake system can lead to serious accidents. Failure to comply may result in death, personal injury, equipment or property damage.
OPERATING THE BRAKE SYSTEM these tractors will require greater brake pedal application to provide the equivalent braking to a bobtail tractor not equipped with a proportioning system. 4 Trailer ABS Power Line Communication (PLC) North American on-highway vehicles are equipped with a separate electrical circuit to power the anti-lock brake system (ABS) on towed vehicle(s). In most cases, the ABS power will be supplied through the Auxiliary circuit on the primary 7-way trailer light line connector.
OPERATING THE BRAKE SYSTEM NOTE CAUTION For doubles or triples, the lamp does not distinguish between trailers. An ABS problem in any of the trailers will activate the Trailer ABS Warning Lamp. The center pin of the 7-way trailer light line may be constantly powered for ABS. Make sure it will not accidently turn on trailer equipment. NOTE If you change the intended service in any way (i.e. number of axles, multiple trailers, add switchable trailer accessories, etc.

ESC is a feature for ABS-equipped vehicles that reduces the risk of rollovers, jackknifing and other loss of control situations. ESC features include Roll Stability Program (RSP) and Yaw Control.
OPERATING THE BRAKE SYSTEM Yaw Stability Yaw Control Yaw stability counteracts the tendency of a vehicle to spin about its vertical axis. During operation, if the friction between the road surface and the tires is not sufficient to oppose lateral (side) forces, one or more of the tires can slide, causing the truck/tractor to spin. Yaw Control responds to a wide range of low- to high-friction surface scenarios including rollover, jackknife and loss of control.
OPERATING THE BRAKE SYSTEM ESC May Reduce The Vehicle Speed Automatically To minimize unexpected deceleration and reduce the risk of a collision the operator must: 4 • Avoid aggressive driving maneuvers, such as sharp turns or abrupt lane changes at high speeds, which might trigger the stability system. • Always operate the vehicle safely, drive defensively, anticipate obstacles and pay attention to road, weather and traffic conditions.
OPERATING THE BRAKE SYSTEM • • tractor or trailer resulting in uneven loads, To Maximize The Effectiveness Of ESC The vehicle is maneuvering on a high banked road creating either additional side forces due to the weight (mass) of the vehicle or a deviation between expected & actual yaw rates, • Loads must be properly secured and evenly distributed at all times.
OPERATING THE BRAKE SYSTEM WARNING! For vehicles equipped with ESC "Electronic Stability Control" do not replace the vehicle’s steering wheel with an aftermarket or different part number than originally supplied. Using a different steering wheel could cause ESC to malfunction causing a loss of vehicle control possibly resulting in an accident involving death or personal injury.
OPERATING THE BRAKE SYSTEM drive wheel brakes or reducing engine torque. Engine torque or vehicle speed should be reduced to eliminate wheel spin and prevent excessive application of the ATC system. Except for checking for proper illumination of the ABS and traction control warning lamps when first starting the vehicle, and for monitoring these lamps while driving, no special operating procedures are required.
OPERATING THE BRAKE SYSTEM • Improves vehicle control and helps reduce stopping distances in off-road conditions or on poor traction surfaces such as loose gravel, sand and dirt. • Allows retarders to function independently of the ABS function. • If your vehicle does not have an engine retarder, the Off-Road ABS switch will function the same.
OPERATING THE BRAKE SYSTEM Hydraulic Brakes WARNING! Do not operate the vehicle in the event of a malfunction in any air or hydraulic circuit. Such a malfunction may prevent the brake system from operating properly, and could result in an injury accident. The vehicle should not be operated until the system is repaired and both braking circuits, including all pneumatic, hydraulic, and mechanical components are working properly.
OPERATING THE BRAKE SYSTEM Brake Components WARNING! The brake system is a critical vehicle safety system. For the safety of you and others around you, have the vehicle submitted for periodic preventive maintenance checks as well as having any suspected problems immediately checked by an Authorized Service Center. Failure to properly maintain your brake system can lead to serious injury accidents. 4 The following is a brief description of the hydraulic brake system.
OPERATING THE BRAKE SYSTEM to the hydraulic booster in the event power steering fluid stops flowing through the booster head. Front and Rear Wheel Calipers: translate hydraulic fluid pressure into force applied at each wheel-end brake rotor to retard wheel motion. Hydraulic Booster: The hydraulic booster applies additional hydraulic force from the power steering gear to the master cylinder piston when the brake pedal is applied.
OPERATING THE BRAKE SYSTEM If the buzzer sounds while driving, or if the BRAKE light comes on, do the following: 1. 4 4. Turn on the emergency flasher and use other warning devices to alert other motorists. Downshift - Putting the transmission into a lower gear will help slow the vehicle. ° Pump the brakes - Pumping the brake pedal may generate enough hydraulic pressure to stop the vehicle. ° Move a safe distance off the road and stop. 3. Set the parking brake.
OPERATING THE BRAKE SYSTEM Overheated Brakes While traveling down steep hills, gravity will tend to speed you up. You must go slow enough that your brakes can hold you back without getting too hot. If you ride the brake pedal and the brakes get too hot, they may "fade", causing you to press even harder in an attempt to maintain your desired stopping power. The brakes may even fade so much that you won’t be able to slow down or stop at all.
OPERATING THE BRAKE SYSTEM Parking Brake Burnishing 40 pounds) until the vehicle is brought to a stop. Do not allow the wheels to lock up. WARNING! 4 No indication will be given via the dashboard warning lights or buzzer if tires of the wrong size are installed on your vehicle. The Anti-Lock Brake System (ABS) is calibrated for the specific tire revolutions per mile.
OPERATING THE BRAKE SYSTEM Retarders Various retarders are available which function against the engine, driveline, or transmission. These are devices that use your engine’s power to slow down your vehicle. They save wear and tear on your service brakes and can be a safety feature, too, because they can keep your brakes from overheating. Ideally, you should always slow your vehicle with your retarder (where permitted by law) and use your service brakes only for stopping completely.
OPERATING THE BRAKE SYSTEM Driving Bobtail or with an Unloaded Trailer We recommend that you do not use your engine retarder to slow down when you are bobtailing or pulling an empty trailer. WARNING! 4 Using an engine retarder can cause a wheel lockup. The trailer is not loading the tires enough to give the traction you may need. When you are bobtail or unloaded, you can have a serious accident if your wheels lock suddenly during braking. You could be killed or injured.
OPERATING THE BRAKE SYSTEM Parking Brake Parking brakes work in reverse action of the regular brakes. When the parking brakes are engaged, air is exhausted from the spring chambers which allow the spring to engage the brakes. This design also provides for the safety function if a brake circuit has a leak and loses air. In such a scenario, the parking brakes will apply. brakes but will not disengage the trailer parking brakes (if applicable).
CRUISE CONTROL CRUISE CONTROL (48 km/h) for the Cummins and PACCAR PX series engines) and the engine speed is above 1100 rpm. Cruise Control Switch This vehicle may have cruise control switches located on the steering wheel instead of the switches on the dash board. The instructions are still the same. • 4 To Turn On: Press the ON/OFF button. • To Turn Off: Press the ON/OFF button. Any previous speed settings are cleared. 2. Press the "ON/OFF" button. 3.
CRUISE CONTROL • Press the ON/OFF button if the vehicle has dash board mounted cruise control switches or the CANCEL button if the vehicle has cruise control switches on the steering wheel. Setting Idle Speed 1. Ensure parking brakes are applied. 2. Ensure transmission is in Neutral. 3. Engage PTO per the manufacturer's operating instructions. 4. Press the "ON" button. 5. Press the "SET" button to obtain the desired engine rpm. Resuming Cruise Control 1. 2.
CRUISE CONTROL In vehicles with Eaton transmissions, the cruise control switches may be located on the shift control knob.
AXLE AXLE Differential Lock The vehicle may be equipped with switches to lock the either of the rear axle differentials. Depending on how the vehicle is specified, a combination individual switches may be available that can lock the interaxle driveline and/or any combination of the forward rear or rear-rear driving axles. The interaxle differential switch allows each axle to turn independently.
AXLE Dual Range (Two-Speed) Rear Axle Your vehicle may be equipped with a two-speed or dual range axle (option). You can select two rear axle ratios for operating under heavy loads or rough terrain as well as for over the road hauling. 4 The Low Range provides maximum torque for hauling heavy loads or traveling over rough terrain. The High Range is a faster ratio for highway speeds and general over the road conditions. A switch on the accessory switch panel controls the Dual Range Rear Axle.
AXLE Starting-Up 1. Unlock the inter-axle differential before starting. 2. Put the Range Selector in the LOW range. Shift the transmission to start the vehicle moving. 3. When you are driving on rough terrain and secondary roads, or under a very heavy load, keep the axle in the LOW range. Shift the transmission to maintain proper road speed. WARNING! Never shift the axle when moving downhill.
AXLE LOW to HIGH (Cruising) HIGH to LOW (Rough Terrain) When you go from rough terrain to highway driving, shift the axle to the HIGH range following this procedure: If you need to downshift the axle for more power or you are driving on rough terrain: 1. 1. 2. 3. 4 4. Be sure the differential is UNLOCKED. Maintain your vehicle speed (accelerator depressed) and move the Range Selector lever to LOW. Maintain your vehicle speed (accelerator depressed) and move the Range Selector lever to HIGH. 2.
AXLE GAWR and the load that is being carried. The vehicle will have switches on the dash to control the position of the auxiliary axles. In certain situations, however, the system will override the controls to protect the axle system. Any liftable and steerable auxiliary axles will rise off of the ground when the parking brakes are engaged or when the vehicle is put in reverse.
AXLE 4 Axle Creep Rating Definition Creep Ratings ratings are generally limited to the following: Low speed, off-highway (work site) axle loads, which exceed the standard gross axle weight rating (GAWR) of a particular axle.
AXLE CAUTION A change in tire size on either the auxiliary axles or the drive/steer axles can change the calibration of the auxiliary axles. If tires are installed with a different loaded radius, the calibration procedure must be repeated. Failure to do so can cause equipment damage.
AXLE General Calibration Guidelines 4. These instructions are general in nature. For more specific instructions, review the pusher or tag suspension manufacturers maintenance manual or contact the nearest authorized dealer. NOTE 4 Perform this procedure at or near a weight scale. Procedure can be performed while parked on the weight scale if scale is available. 1. Park loaded vehicle on level surface with wheels blocked. 2. Release vehicles spring brakes.
AXLE Maximizing Drive Axle Traction Coupling To A Loaded Trailer Unloading Operation Adjust the pressure regulator control knob to a lower pressure until desired traction is obtained. By reducing air pressure at pusher or tag axle, load will be transferred to drive axles. Do not overload drive axles. Inflate air springs of the auxiliary axles to the desired pressure after coupling to a loaded trailer while still maintaining proper traction of the drive axles.
AXLE Non-liftable (Non-steerable) Axles Some suspensions require dump valve calibration. Example: Neway dead axles do not lift, but the air can be dumped out of them to unload them when empty. Air pressure is controlled via an adjustable regulator. These axles need to be calibrated for load. 4 Contact your authorized dealer or axle/suspension manufacturer for dump valve calibration procedures.
SUSPENSION SUSPENSION Unladen Vehicle Proprietary Rear Setting Ride Height Vehicles equipped with rear air suspensions have their ride height and axle (pinion) angle(s) preset at the factory. These are precision settings and should not be altered. Incorrectly adjusted ride height may result in improper interaxle U-joint working angles. This can result in premature driveline wear and driveline vibration.
SUSPENSION WARNING! Ensure that a vehicle is parked and the wheels chocked before beginning this procedure. 2. Ensure the air supply and delivery plumbing of the height control valve is consistent with the following illustrations. CAUTION 4 Completing this procedure will enable you to safely reach the nearest authorized Peterbilt repair facility to have ride height and pinion angle reset using the proper equipment and technique. Do this as soon as possible to avoid potential driveline damage.
SUSPENSION WARNING! • • • The rear of a vehicle will drop about 3 1/2 inches (88 mm) when the air springs are deflated. Ensure that no persons or objects that could be killed, injured or damaged are under the vehicle before deflating the air springs. To minimize risk of death, personal injury or property damage, do not use a dump valve to deflate the air springs. Rotate the height control valve(s) manually to ensure positive control of air spring deflation.
SUSPENSION Driving with Deflated Air Springs If an air spring is ruptured, there will be enough air pressure to drive the vehicle to a safe stop off the highway to investigate the problem. WARNING! 4 Do not continue to drive with ruptured air springs. The air loss can cause the spring brakes to apply allowing your brakes to drag and burn up the linings, which could lead to an accident causing death or personal injury. Do not continue to operate the vehicle in this condition.
AFTER-TREATMENT SYSTEM AFTER-TREATMENT SYSTEM Introduction This vehicle will has an exhaust After-Treatment System (ATS), to control vehicle exhaust emissions, which consist of a Diesel Particulate Filter (DPF), Selective Catalyst Reduction (SCR), Regeneration Switch and warning lights. The DPF will trap soot from the engine exhaust gases. The SCR uses Diesel Exhaust Fluid to reduce the levels of NOx in the engine exhaust. The ATS will periodically clean (regenerate) the DPF.
DRIVING TIPS AND TECHNIQUES DRIVING TIPS AND TECHNIQUES Introduction This section covers additional driving tips and techniques on how to drive your vehicle more efficiently. 4 Coasting WARNING! Do not coast with the transmission in neutral or with the clutch pedal depressed—it is a dangerous practice. Coasting in neutral may result in damage to your drivetrain when you try to re-engage the transmission.
DRIVING TIPS AND TECHNIQUES Descending a Grade Engine Overspeed WARNING! CAUTION Do not hold the brake pedal down too long or too often while going down a steep or long grade. This could cause the brakes to overheat and reduce their effectiveness. As a result, the vehicle will not slow down at the usual rate.
DRIVING TIPS AND TECHNIQUES Use of Tachometer The tachometer is an instrument that aids in obtaining the best performance of the engine and manual transmission, serving as a guide for shifting gears. to the engine. However, the governor has no control over the engine rpm when it is being driven by the vehicle's transmission, for example, on steep downgrades. Apply service brakes or shift to a higher gear. Refer to the Engine Operation and Maintenance manual for optimum engine rpm.
DRIVING TIPS AND TECHNIQUES Maintenance Proper maintenance will keep the vehicle running like new even after long periods of use. The driver must perform the daily and weekly checks of the vehicle.
DRIVING TIPS AND TECHNIQUES General Condition Other factors affecting fuel consumption are related to loads and type of roads on which the vehicle operates. It is not always possible to choose the most adequate road, but it must be kept in mind that the ideal road is the one that allows a steady speed in high gear, without requiring frequent braking and acceleration.
STOPPING THE ENGINE STOPPING THE ENGINE Turbochargers Refueling Before Stopping the Engine This cooling-down practice is especially important on a turbocharged engine. The turbocharger contains bearings and seals that are subjected to hot exhaust gases. While the engine is operating, heat is carried away by circulating oil. If you stop the engine suddenly, the temperature of the turbocharger could rise as much as 100°F (55°C) above the temperature reached during operation.
STOPPING THE ENGINE Location of Fuel Shut-Off Valves Refuel Before the Final Stop If your vehicle is equipped with shut-off valves for the take-off and return lines, they are located on the fuel lines entering the top of the fuel tank. Fuel shut-off valves for the fuel crossover line are on the bottom of the fuel tank, at the crossover line connection. Air space in your fuel tanks allows water to condense there. To prevent this condensation while you are stopped, fill your tanks to 95% of capacity.
STOPPING THE ENGINE Final Stop Final Stopping Procedures To make sure your vehicle is ready to go after a long stop (such as over night), please follow the suggestions below. Your vehicle will be easier to get going when you are ready, and it will be safer for anyone who might be around it. Please remember, too, that in some states it is illegal to leave the engine running and the vehicle unattended. 1. Set the parking brake before leaving the driver’s seat.
STOPPING THE ENGINE air supply. Be sure to close the drains before leaving the vehicle. 4 Opening Drains 4. Secure the vehicle. Close all the windows and lock all the doors.

In addition to pre-delivery inspections, suspension alignment should be checked when any one of the following conditions exist: • Discovery of loose suspension fasteners.
STEERING SYSTEM STEERING SYSTEM WARNING! Power Steering Do not operate the vehicle if the steering system is not working properly. You could lose control of your vehicle if the steering system is not in good working condition, which could result in a serious accident. For driving safety, visually check the steering gear and components. Frequent checks are important for driving safety, especially after traveling over rough roads.
STEERING SYSTEM • Draglink tube clamp: Check for looseness or interference. • Ball joints and steering U-joints: Check for looseness. • Steering wheel for excessive free-play. Check the simplest probable causes first: • Fluid Level and Refill • Maximum/Minimum level is indicated on the reservoir. These same levels are also indicated by two lines on the dipstick in the reservoir. • There are two ways to check whether the power steering fluid is at its proper level.
STEERING SYSTEM between the Maximum and Minimum level indicators. Fluid Filter Replacement Steering Shaft The following are common torque specifications for most steering shafts. • Torque on U–joint pinch bolt and nut (7/16 in) 74–81 Nm (55 to 60 lb-ft), lubricated. • Torque on Pitman arm clamp bolt and nut (3/4 in): 406–433 Nm (300 to 320 lb-ft), lubricated. • For off–highway vehicles, tighten the U–bolts after the first day or two of operation. Then check weekly.
STEERING SYSTEM WARNING! If this chassis is equipped with an electronic stability system (ESC) and any part of the steering system (e.g. linkage, steering driveline, column, front-end alignment, etc) is repaired, removed, or disassembled in any way, or if the steering angle sensor is replaced, the steering angle sensor must be recalibrated. Any repairs or adjustments to any part of the steering system must be performed by an authorized dealer.
DRIVELINE DRIVELINE U-Joints For SPL170XL and SPL250XL, the U-joint lube interval changes after the initial lube at 350,000 miles. After the first lube interval, the U-joint needs lubrication every 150,000 miles. Inspection of the U-joints is the same regardless of when the U-joint grease interval happens. Driveshaft Maintenance The slip joints and universal joints of the driveshaft should be lubricated periodically. Use a good quality lithium-soap-base or equivalent extreme pressure (E.P.
TIRES AND WHEEL TIRES AND WHEEL Tires WARNING! Regular, frequent inspection and the right care will give you the assurance of safe and reliable tire operation. Here are some tips on maintaining your tires. Do not repair damaged tires unless you are fully qualified and equipped to do so. Wheel and tire assemblies cannot be worked on without proper tools and equipment, such as: safety cages or restraining devices. Have all tire repairs performed by an expert.
TIRES AND WHEEL Underinflated Tires Low pressure is a tire’s worst enemy. Underinflation allows tires to flex improperly, causing high temperatures to build up. Heat causes early tire damage such as flex break, radial cracks, and ply separation. Low pressure may affect control of your vehicle, especially at the front wheels. Most tire wear problems are caused by underinflation as the result of slow leaks, so you’ll want to check tire pressure regularly.
TIRES AND WHEEL Overloaded Tires 1 3 Proper-Inflation: the correct profile for full contact with the road. TREAD CONTACT WITH ROAD TREAD CONTACT WITH ROAD Over-Inflation: reduces the tread contact area with the road surface, concentrating all of the vehicle weight on the center of the tread. This causes premature wear of the tire. Overloading your truck is as damaging to your tires as underinflation. The following chart shows how neglect or deliberate abuse can affect the life of your tires.
TIRES AND WHEEL Overinflated Tires Matching Tires Too much air pressure reduces the tire tread contact area and results in rapid wear in the center of the tread. Be sure to buy matched tires for your vehicle, especially on the rear axles. Mismatched tires can cause stress between axles and cause the temperature of your axle lubricant to get too hot. Matched tires will help your driveline last longer and will give you better tire mileage. WARNING! WARNING! 5 Overinflated tires can cause accidents.
TIRES AND WHEEL Replacing Tires Greenhouse Gas Certified Tires WARNING! Front: Replace front tires when less than 4/32 in. of tread remains. Check at three places equally spaced around the tire. Drive Axles or Trailers: Replace tires on drive axles or trailers when less than 2/32 in. of tread depth remains in any major groove. Check at three places equally spaced around the tire. See the next illustration for recommended measuring points for tread depth.
TIRES AND WHEEL Maintaining a greenhouse gas certified tire. In order to limit the rolling resistance of the tires and optimize fuel economy, the maintenance procedures specified by the tire manufacture must be followed. For warranty information, See Greenhouse Gas Tires on page 6-9. Speed Restricted Tires Tire Chains If you need tire chains, install them on both sides of each driving axle.
TIRES AND WHEEL Wheel Mounting and Fastening After the vehicle travels about 50 to 100 miles (80 to 160 km), wheel mountings seat in and will lose some initial torque. Check hub/wheel mountings after this initial period and retighten. Wheel Cap Nut Torque WARNING! Never use oil or grease on studs or nuts; improper torque readings will result, which could cause improper wheel clamping and could lead to a wheel failure resulting in an accident.

TIRES AND WHEEL Wheel Replacement With Disc Brake Option WARNING! Tighten wheel cap nuts properly. If they are not tightened properly, wheel nuts could eventually cause the wheel to become loose, to fail, and/or to come off while the vehicle is moving, possibly causing loss of control and may result in death, personal injury, equipment or property damage.
TIRES AND WHEEL with the disc brake assembly. When installing any replacement wheel, always inspect the tires/wheels to ensure there is adequate clearance between other vehicle components. With the hood open, check for clearance between the wheel and disc brake assembly. Use a hydraulic jack to raise the front of the vehicle off the ground to allow the wheel to spin freely.
TIRES AND WHEEL Disc Wheels WARNING! Use the correct components and tools when working on wheels. Grooves in the wheel disc or other damage to the disc can weaken the wheel and cause it to eventually come off. This could cause you to lose control of your vehicle, and may result in an accident. Failure to comply may result in death, personal injury, equipment or property damage. The end of the wheel wrench must be smooth. Burrs on the end of the wrench can tear grooves in the disc.
WHEEL BEARING WHEEL BEARING Wheel Bearing Adjustment For safe, reliable operation and adequate service life, your wheel bearings must be adjusted properly at the recommended intervals. Contact your authorized dealer to make sure the wheel bearings are properly adjusted.
TRANSMISSION AND CLUTCH TRANSMISSION AND CLUTCH Introduction Follow these steps to ensure parts are properly lubricated: • Maintain oil level, check it regularly • Change oil regularly • Use the correct grade and type of oil • Buy oil from a reputable dealer All Transmissions Oil Change: Drain and replace according to Preventive Maintenance Schedule on page 5-12 and the Transmission Service Manual.
TRANSMISSION AND CLUTCH Manual Transmissions of oil circulated by the motion of gears and shafts.

TRANSMISSION AND CLUTCH called release travel. And finally, on 9-, 10-, and 11-speed transmissions, as the pedal is pushed to the last 1/2 to 1 inch of travel, the release bearing contacts and engages the clutch brake. This is called clutch brake squeeze. When the clutch wears, the release bearing gradually moves toward the engine, decreasing free pedal and free travel. When all free pedal and free travel are gone, the clutch requires adjustment.
TRANSMISSION AND CLUTCH Automatic Transmissions Automatic Transmission Oil Level Service Intervals NOTE Check daily with engine idling. See Preventive Maintenance Schedule on page 5-12 for service intervals. The vehicle must be parked on level ground. See the Transmission Operator's Manual for information on checking the transmission oil level.
