WHAT TO DO IF... WARNING! CAUTION Do not replace a fuse with a fuse of a higher rating. Doing so may damage the electrical system and cause a fire. Failure to comply may result in death, personal injury, equipment or property damage. 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.
WHAT TO DO IF... Fuse Inspection and Replacement 2 All the electrical circuits have fuses to protect them from a short circuit or overload. If something electrical on your chassis stops working, the first thing you should check for is a blown fuse. 1. Turn OFF all lights and accessories and remove the ignition key to avoid damaging the electrical system. 2. Determine from the chart on the fuse panel which fuse controls that component. 3. Remove that fuse and see if it is blown.
JUMP STARTING VEHICLES JUMP STARTING VEHICLES 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! 2 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. 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! 2 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. 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 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.
VEHICLE RECOVERY AND SPRING BRAKES Recovery Procedure 1. 2 Review and understand all the cautions and warnings of this section, see Vehicle Recovery Guidelines on page 2-15. 2. Install the recovery hitches, see Recovery Hitch Installation on page 2-18. 3. Disconnect the drive axle shafts and cover the open hubs. This is necessary because if the transmission is driven by the driveshaft (rear wheels on the ground), no lubricant will reach the gears and bearings, causing damage to the transmission. 4.
VEHICLE RECOVERY AND SPRING BRAKES Technology and Maintenance Council 950 N. Glebe Road (703) 838-1763 Arlington, VA 22203 Email: tmc@trucking.org tmc.truckline.com Recovery Hitch Connection Specially designed hitches are required to recover your vehicle. The recovery hitches attach to the frame. 2 Two hitch assemblies, made up of the following parts, are recommended for the proper recovery of your vehicle.
VEHICLE RECOVERY AND SPRING BRAKES 2 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. Check square sockets behind lower bumper for obstructions, clear if necessary. 2. With lock pins removed, insert hitches through bumper and into the square hitch socket. 3.
VEHICLE RECOVERY AND SPRING BRAKES 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. When vehicles are towed either by wrecker or piggyback, lubricant in the top front of the drive axle will drain to the rear.
VEHICLE RECOVERY AND SPRING BRAKES 2 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. Do not attach to bumpers or brackets. Connections to other structural parts could damage the vehicle. • • 4. If you desire to use the recovered vehicle’s brakes, ensure that the vehicles air system is connected to that of the recovery vehicle.
VEHICLE RECOVERY AND SPRING BRAKES Recovery Rigging To connect to the vehicle, follow the suggested rigging methods below. • Use a double chain or cable setup that distributes the load equally to both hitches. • Never loop a single chain or cable through both hitches. • Use a spreader or equalizer bar to distribute the load on both hitches. • If no spreader bar is available, connect the main tow chain or cable no closer than 6 ft. from the vehicle. 2 1.
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.

STANDARD GAUGES STANDARD GAUGES Introduction by an audible alarm, whenever the limits of the function being displayed are exceeded. On the pages that follow you will find descriptions of some of the gauges on your instrument panel. For more information about using them in driving, see “Starting and Operating the Vehicle” Also check the Index under the name of the gauge or function you want to know more about.
STANDARD GAUGES Odometer / Trip Meter The LCD display in the lower part of the speedometer contains the odometer and trip meter. 3 The odometer displays the total distance your vehicle has traveled. It will display in miles on an English speedometer or in kilometers on a metric speedometer. The maximum distance that can be shown on the odometer is “1 999 999” before it rolls over to zero. The trip odometer displays how far the vehicle has gone on a particular trip.
STANDARD GAUGES Engine Hours / Outside Air Temperature The LCD display in the lower part of the tachometer contains the engine hour meter and the outside air temperature display. The engine hour meter will display the total number of hours the engine has been running. The maximum hours that can be shown are “99999.9” before the meter rolls over to zero. The outside air temperature (OAT) will display the temperature outside the vehicle.
STANDARD GAUGES Fuel Gauge The fuel gauge shows the approximate amount of fuel in the fuel tanks. Besides empty and full, the gauge also indicates 1/4, 1/2, and 3/4 of total capacity. You will want to keep your fuel tanks at least half full to reduce condensation of moisture in the tanks. This moisture can damage your engine. 3 Primary (Secondary) Air Pressure Gauge (Air Reservoir) The air pressure gauge indicates the amount of air pressure in the brake system in pounds per square inch (psi).
STANDARD GAUGES WARNING! Ensure the air pressure registers more than 100 psi in both service systems before you move the vehicle. If the pressure in either circuit is too low for normal brake operation, the warning light will glow and the audible alarm will sound. (03/17) The air pressure warning light and the audible alarm indicate a dangerous situation. There is not enough air pressure in the reservoirs for repeated braking and the brake system has failed.

The following instructions are 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 CAUTION 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.
OPERATING THE TRANSMISSION OPERATING THE TRANSMISSION Operating Clutch (Manual Transmission) 4 Manual transmissions will also have a clutch pedal situated to the left of the brake pedal. Pressing down on the clutch pedal will disengage the clutch and will allow the transmission gears to be shifted. At the beginning of the pedal stroke, there will be about 1 3/4 in. to 2 in. (34 to 51 mm) of movement before any resistance is felt.
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 Driving Tips and Techniques on page 4-44. 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 vehicle start forward, until the clutch is fully engaged. See the manufacturer's Driver/Operator's Instruction Manual for further details. If the transmission has a butt-tooth condition and you cannot engage a gear, gradually release the clutch. Then the drive gear can roll enough to allow the teeth to line up properly and complete the shift.
OPERATING THE TRANSMISSION b. 4. 5. 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. 4 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.
OPERATING THE TRANSMISSION Auxiliary Transmission WARNING! If your vehicle has an automated transmission, be aware that it can roll backwards when stopped on a hill or grade, or when starting from a stop on a hill or grade. Failure to comply may result in death, personal injury, equipment or property damage. Observe the following guidelines: • When stopped on a hill or grade, press the brake pedal.
OPERATING THE TRANSMISSION 4 • Never downshift when the vehicle is moving too fast. • Never slam or jerk the shift lever to complete gear engagement. • Never coast with the transmission in neutral and the clutch disengaged. • To provide smooth gear engagements while shifting, use proper coordination between shift lever and clutch. Double clutching is a very effective means to increase the service life of your transmission.
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. 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 4 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. 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 4 If you change the intended service in any way (i.e. number of axles, multiple trailers, add switchable trailer accessories, etc.
OPERATING THE BRAKE SYSTEM Advanced ABS with Stability Control This vehicle may be equipped with an optional Electronic Stability Control (ESC). 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 4 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: • 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 There are mechanical problems with suspension leveling of the tractor or trailer resulting in uneven loads, To Maximize The Effectiveness Of ESC • 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 4 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 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. 4 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! 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 mph (48 km/h) for the Cummins 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 dashboard. The instructions are still the same. • Press the "ON/OFF" button. 3. Accelerate the vehicle to the desired cruise speed. 4. Press the "SET" button to set the cruise speed. To Turn On: NOTE Press the ON/OFF button. • 2.

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. 4 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. 4 The interaxle differential switch allows each axle to turn independently.
SUSPENSION SUSPENSION Fully Laden 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 pre-mature driveline wear and driveline vibration.
SUSPENSION Unladen Vehicle Proprietary Rear Air Suspension Ride Height, inches (mm) Single Drive Tandem Drive Low Low Air Leaf N/A 6.75 (171) FLEX Air N/A 8.75 (222) Follow this procedure to temporarily set ride height. 4 WARNING! Ensure that a vehicle is parked and the wheels chocked before beginning this procedure.
SUSPENSION WARNING! NOTE • At least one of the mounting holes in the height control valve bracket will be slotted to permit rotating the valve. • On dual-valve systems, begin with the LH valve on the next step. 3. Loosen the fasteners mounting a height control valve to its bracket. • • • (03/17) The rear of a vehicle will drop about 3 1/2 inches (88 mm) when the air springs are deflated.
SUSPENSION 6. Torque the mounting fasteners to 55-75 Lb. in. (6.2-8.5 Nm.). 7. Remove the alignment pin or dowel. 8. Repeat Steps 2 through 6 above for the RH valve on vehicles with a dual-valve system. 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! Do not continue to drive with ruptured air springs.
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 Use of Instrument Cluster Display Fuel - Excess Consumption Maintenance The Instrument cluster display provides information to help the driver optimize vehicle efficiency. Refer to Instrumentation Cluster Information on page 3-35 for details. A driver will find the section describing Trip Information and the RPM Detail useful.
DRIVING TIPS AND TECHNIQUES Maintenance factors affecting fuel consumption: 4 • air and/or fuel filters partially clogged • engine valves out of adjustment • injection pump improperly synchronized • injection nozzles defective or uncalibrated • improperly inflated tires • wheel bearings improperly adjusted • clutch improperly adjusted or worn (slipping) • Driving Habits General Condition Wrong driving habits must be corrected and the recommendations on economic driving should be followed.
SLEEPER BUNKS SLEEPER BUNKS WARNING! Sleeper Bunk If your vehicle has an upper and lower bunk, the upper bunk can be folded up out of the way to provide you with more dressing area in the sleeper cab. The lower bunk has storage underneath it to stow your luggage and other belongings. The upper bunk weight limit is 320 lb (145 kg). WARNING! Be sure the restraint system is used when anyone is occupying the sleeper while the vehicle is moving.
SLEEPER BUNKS Sleeper Occupant Restraint WARNING! Be sure the restraint system is used when anyone is occupying the sleeper while the vehicle is moving. In an accident, an unrestrained person lying in a sleeper bunk could be injured. He or she could be thrown from the bunk. Failure to comply may result in death or personal injury. 4 WARNING! Be sure no one ever rides unsecured in the upper bunk. That person could be thrown out in an accident and could be injured.
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. Common Maintenance Items Inspection of the Engine Oil Level Accessory Drive Belts NOTE You can extend the reliability and service life of your vehicle's drive belts with proper attention to installation, and maintenance. Neglect could cause belt failure. The result could be the loss of the electrical or air system as well as possible engine damage from overheating.
STOPPING THE ENGINE 1. 2. Make sure that the vehicle frame rail is standing on a flat and level surface. 7. Reinstall the dipstick and twist to lock it in place. Make sure that the vehicle is horizontal, both lengthwise and crosswise. Check this carefully on a vehicle with air suspension. Note that the engine may be inclined up to 4° depending on the vehicle model and wheelbase. 3. Twist the dipstick handle to unlock it, then pull the dipstick out of the holder. 4.
STOPPING THE ENGINE Engine Air Intake Filter Cooling System Maintenance This vehicle is equipped with an air inlet restriction indicator. Service the filter elements when the air inlet restriction indicator locks in the extreme Up position. Paper elements require care and proper handling because they are critical to engine service life. If your vehicle has an external air cleaner and cab-mounted mirrors, the mirror must be pivoted to provide access for servicing the filter element.
STOPPING THE ENGINE Proper Coolant Level Topping Off NOTE • • NOTE WARNING! Do not overfill a cooling system. Excess coolant may result in overflow, loss of antifreeze, and reduced corrosion protection. Removing the fill cap on a hot engine can cause scalding coolant to spray out and burn you badly. If the engine has been in operation within the previous 30 minutes, be very careful in removing the fill cap.
STOPPING THE ENGINE Power Steering CAUTION Oil (under low pressure) provides the power to operate the steering gear. It also serves to lubricate moving parts and remove heat. A loss of steering efficiency will occur if too much heat builds up in the system. When adding fluid, be sure to use fluid of the same type. While many fluids have the same description and intended purpose, they should not be mixed due to incompatible additives. Mixing incompatible fluids may lead to equipment damage.
STOPPING THE ENGINE 1. 2. If you check the fluid with the engine and steering system COLD, the fluid level should be at/or above the Minimum indicator level and should generally not exceed the middle point between Maximum and Minimum level indicators. If you check the fluid with the engine and steering system WARM, the fluid should NOT exceed the Maximum level indicator and should generally not drop below the middle point between the Maximum and Minimum level indicators.
STOPPING THE ENGINE Fuse Inspection and Replacement Wheel Cap Nut Torque If a fuse is blown, see What to do if fuse or relay blows on page 2-6 for more information. 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, see the Maintenance and Consumer Information Manual for sequence and specifications.
