DRIVING - Starting and Operating Starting and Operating For detailed information on starting and operating the engine, refer to the Engine Operation and Maintenance Manual provided with your vehicle. 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.
DRIVING - Starting and Warming Up 4 procedure. If Anti-Theft is enabled, the first time you turn the ignition switch to START, you will need to enter the Passcode. 1. Set the parking brake. 2. Put your main transmission in Neutral. 3. Disengage (depress) the clutch (with manual transmission). 4. Turn the ignition switch to START. NOTE If Anti-Theft is enabled, you will need to enter the Passcode in order to start the engine (see Anti-Theft). 5.
DRIVING - Starting and Warming 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. Engine, Under Hood Air Intake This switch opens a door in the engine air filter housing so that the air is taken from under the hood instead of outside air.
DRIVING - Starting and Warming Up NOTE Under most circumstances, idling your engine for long periods merely wastes fuel. In severe arctic weather conditions, however, you may need longer idling to be sure all parts of your engine are fully lubricated. 4 WARNING Exhaust fumes from the engine contain carbon monoxide, a colorless and odorless gas. DO NOT breathe the engine exhaust gas. A poorly maintained, damaged, or corroded exhaust system can allow carbon monoxide to enter the cab.
DRIVING - Engine Operations NOTE Keep the engine exhaust system and the vehicle's cab ventilation system properly maintained. It is recommended that the vehicle's exhaust system and cab be inspected (1) By a competent technician every 15,000 miles (24,140 km); (2) Whenever a change is noticed in the sound of the exhaust system; or (3) Whenever the exhaust system, underbody, or cab is damaged.
DRIVING - Engine Operations should observe during this process; however, defer to your PTO manufacturer's Operating Instructions in all cases where there is a disagreement in instruction. NOTE Actual PTO engagement/disengagement may be delayed momentarily since it is controlled by the air system and mechanical movement. 4 CAUTION Increasing engine rpm before the PTO is actually engaged could prevent the PTO from engaging and/or cause PTO damage. 1. 2.
DRIVING - Engine Operations WARNING 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. Failure to comply may result in death or personal injury.
DRIVING - Engine Operations 4 System (EAS), to control vehicle exhaust emissions. The Engine Aftertreatment system consist of a Diesel Particulate Filter (DPF), Selective Catalyst Reduction (SCR), DPF 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 EAS will periodically clean (regenerate) the DPF.

A visual and audible alert will occur when a lane marking is unintentionally crossed. The operator can mute the Lane Departure Warning (LDW) audible alarm by using the Lane Departure/ Electric Steer Assist switch.
DRIVING - Transmission WARNING Ultimate responsibility for the safe operation of the vehicle remains with the driver at all times. Even with Lane Departure Warning or Electric Steer Assist, the driver must remain alert, react appropriately and in a timely manner, and use good driving practices. Failure to do so may result in death, personal injury and/or property damage.
DRIVING - Transmission will allow your clutch to slip, causing excessive heat and wear, damage could result. Release Bearing Wear When you must idle your engine for any period of time, shift your transmission to neutral and disengage the clutch (take your foot OFF of the pedal). This helps prevent unnecessary wear to your clutch release bearing, and is less tiring for you, too. More Tips • • • • • • Always use the clutch when making upshifts or downshifts.
DRIVING - Transmission CAUTION 4 Always use first gear or a low speed range to start the vehicle in motion. The use of a higher gear or speed range forces undue strain on the engine, clutch, and other transmission components, and may cause damage. 3. 4. 5. 6. 130 Evaluate the road surface conditions and terrain your vehicle is on. Select a gear low enough to let your vehicle start forward with the throttle at idle.
DRIVING - Transmission How to Use the Hydraulic Clutch CAUTION Be careful not to apply the clutch brake while the vehicle is moving. The purpose of the clutch brake is to stop the transmission so that you can shift into a starting gear without grinding gears. Applying the clutch brake when the vehicle is moving causes a braking effect on the drivetrain and shortens the service life of the clutch brake.
DRIVING - Transmission • 4 Upshifts: let the engine and gears slow down to the rpm required for the next gear. • Downshifts: press accelerator, increase engine and gear speed to the rpm required in the lower gear. 4. Now quickly press the pedal to disengage the clutch and move the gear shift lever to the next gear speed position. 5. Release the pedal to engage the clutch. Automatic Transmissions An automatic transmission makes shifting much easier.

The Automated or PACCAR Transmission controls are located on the right hand side of the steering column.
DRIVING - Hydraulic Brakes NOTE NOTE Today's diesel engines have significant torque and startability power at low rpm. Combinations of engine speed and available torque may over-power the vehicle's parking brakes. 4 Failure to fully release the parking brake before moving can cause the brakes to overheat. 1. 2. Engaging the Parking Brake Vehicles with hydraulic brakes use a manually operated driveline parking brake, actuated by lever and cable.
DRIVING - Air Brake System (option) 5. WARNING If a new drum or new brake shoes are installed, the driveline brake must be burnished. Failure to properly burnish the parking brake before putting it in service could result in an inoperative parking brake, possible vehicle rollaway, and serious personal injury or damage to the vehicle. 1. 2. 3. 4. Drive the vehicle at 15 mph (24 km/h) in a low gear (first or second) on a dry, hard road surface.
DRIVING - Air Brake System (option) 4 takes outside air and compresses it, usually to 100-130 psi (689-896 kPa). The compressor air then goes to the air tanks to be stored until needed. When you operate your air brakes, the stored compressed air flows into the chambers where it is used to apply your truck and trailer brakes. That is why, when you push down on the brake pedal, you do not feel the same amount of pressure on the pedal that you do when you apply the brakes on your car.
DRIVING - Air Brake System (option) automatically pop out. (A dash warning light will indicate when the brake is ON.) Shift the transmission into PARK position: WARNING DO NOT leave the cab of your vehicle without applying the parking brake. The truck could roll and cause an accident resulting in death or personal injury. Always apply the parking brake before you leave the cab. Combination (Vehicle/Trailer) Parking Brake Control Valves 2. • manual transmission, select First or Reverse gear.
DRIVING - Air Brake System (option) 2. CAUTION Do not try to put the vehicle in motion before pressure in the system reaches 100 psi (689 kPa) because the wheels are locked by the spring brake action. Unnecessary stress and possible brake malfunction could occur if the vehicle is forced to move before the air system reaches 100 psi (689 kPa). Failure to comply may result in equipment damage.
DRIVING - Air Brake System (option) 1 To apply the trailer brakes only: Pull OUT the Red knob. This will exhaust air from the trailer supply line, causing the vehicle protection valve to close and the trailer spring brakes to apply. The trailer is now in emergency or park. This mode would be used to uncouple from the trailer (running without a trailer connected). 2 WARNING 3 1. 2. 3.
DRIVING - Air Brake System (option) Governor NOTE The trailer brake is not to be used as a substitute for the service brakes. Using this brake frequently, instead of using the foot brake, will cause the trailer brakes to wear out sooner. 4 WARNING Using the trailer hand brake or air brakes to hold a parked vehicle is dangerous. Because they work with air pressure, these brakes could come loose. Your vehicle could roll, causing an accident involving death or personal injury.
DRIVING - Brake Safety and Emergency the parking (spring) brakes of the vehicle or of the vehicle-trailer combinations. If the air system is being charged from zero pressure, the parking brake valve will not hold in the release position until the system pressure exceeds 60 psi (414 kPa), which is the pressure required to override the load of this valve's plunger return spring.
DRIVING - Brake Safety and Emergency Automatic Traction Control CAUTION If the ABS warning light does not illuminate when the ignition is first turned on, there is a problem with the bulb or wiring. You should have this checked as soon as possible. 4 WARNING 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.
DRIVING - Brake Safety and Emergency • steering circuit or a pressure differential between the primary and secondary brake circuits. WARNING Do not operate the vehicle if the brake light or buzzer comes on. The light or buzzer indicates a failure in one of the brake components/system. Drive your vehicle to the side of the road immediately. Failure to do this may lead to an accident and severe injury. 2. 3. 4. Use the parking brake - The parking or emergency brake is separate from the hydraulic system.
DRIVING - Retarders Brake Operation WARNING DO NOT drive through water deep enough to wet brake components, as it may cause the brakes to work less efficiently than normal. The vehicle's stopping distance may be longer than expected, and the vehicle may pull to the left or right when brakes are applied, which could contribute to an accident involving death or personal injury.
DRIVING - Retarders WARNING The service brakes must be used in an emergency. The retarder alone might not stop you fast enough to prevent an accident. Failure to comply may result in death, personal injury, equipment or property damage. The retarder is NOT intended as the primary brake for the vehicle, nor is it an emergency brake. The retarder only helps the service brakes by using pressure to slow the drivetrain. Use the service brakes for quick stops.
DRIVING - Retarders 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. DO NOT use your retarder when you are driving bobtail or with an unloaded trailer. 4 • • Make sure the brake is OFF before starting the engine.

Vehicles with an engine braking level switch show the degree of engine braking applied using dots below the indicator.
DRIVING - Axle and Suspension Inter-Axle Differential Lock Operation To LOCK the Inter-Axle Differential 1. NOTE Do not use the differential lock during downhill operation or at speeds above 25 mph (40 km/h). When it is engaged under these conditions, your vehicle will exhibit understeer handling characteristics. This understeer condition will cause your vehicle to not turn as quickly and more steering effort will be required, which can cause an accident.
DRIVING - Axle and Suspension resume and the light on the switch will turn off. 2. 3. Driver Controlled Main Differential Lock If your vehicle has a Meritor axle with a Driver Controlled Main Differential Lock, install the caging bolt before removing the axles for towing. Installation of the caging bolt prevents damage by locking internal axle components in position. Use the procedure below to lock the Meritor differential. Driver Controlled Main Differential Lock 1. 2. 1.
DRIVING - Axle and Suspension CAUTION If you shift the axle range with the inter-axle differential in LOCK, you could seriously damage the axles. Never shift the axle range with the differential locked. 4 Proper shifting of the axle depends on the synchronization of engine/driveline and wheel speed. When you shift the axle, the connection between the engine and wheels is momentarily disengaged while the gearing is synchronized.
DRIVING - Axle and Suspension Auxiliary Axle Adjustable auxiliary axles (commonly known as Pusher or Tag axles) can add to the productivity of the vehicle by increasing the load capabilities of the vehicle when they are in the deployed (down) position. There are different configurations of axles with different functionality (liftable versus steerable).
DRIVING - Axle and Suspension 4 After the trailer is coupled or uncoupled, then increase pressure to balance traction and axle load requirements. 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. 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.
DRIVING - Axle and Suspension • CAUTION DO NOT modify the air system and/or control functionality on a factory installed auxiliary axle(s). Modifying the factory operation of the pusher and/or tag axle(s) will void your warranty, and can cause equipment damage. 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.
DRIVING - Axle and Suspension 5. assist you in achieving an estimated ground load). After setting the pressure to obtain the desired axle load, verify proper ground loading with the weight scale. NOTE 4 Exceeding local, state, or federal weight limits may result in citations. Contact your local commercial weight enforcement office for limits in your area. NOTE Steerable-pusher and/or tag axle(s) will raise when the transmission is shifted into reverse or when the parking brakes are applied.
DRIVING - Axle and Suspension 6. Rotate the valve either clockwise or counterclockwise until air pressure in the air springs provides the ride height specified for that suspension. Measure the ride height from the bottom of the frame rail to the approximate centerline of the rearmost drive axle hub: For tandem axles, make the • vertical measurement at the centerline of the suspension.
DRIVING - Fifth Wheel Suspension Air Pressure Gauge & Switch What to do if an Air Spring Ruptures If an air spring has ruptured, drive the vehicle to a safe stop off the highway to investigate the problem. WARNING 4 Your vehicle may have an air suspension and a deflation switch which allows the air in the suspension to be exhausted from a switch on the dash. The normal purpose of this feature is to allow you to lower the vehicle for loading.
DRIVING - Fifth Wheel WARNING Ensure that all fifth wheel maintenance, adjustments, and rebuilding are done only by a qualified mechanic. An improperly maintained fifth wheel can cause a trailer to separate from a tractor. This could lead to a serious accident. Failure to comply may result in property damage, personal injury, or death.
DRIVING - Fifth Wheel The popup will inform the operator when to release the switch. JOST Fifth Wheel Indication NOTE Do not drive tractor free of trailer. 7. 4 If equipped with JOST Fifth Wheel If the tractor has a rear air suspension, deflate (dump) the rear suspension enough so that the fifth wheel will smoothly separate from the trailer.

DRIVING - Fifth Wheel 4. 5. Disconnect brake air and electric lines from trailer, and secure lines. Unlock the fifth wheel release handle if necessary, then unlock the fifth wheel. NOTE Operating the release handle and unlocking the fifth wheel will depend on the fifth wheel manufacturer. 6. 7. Return to cab and release tractor parking brake. Ease tractor forward enough for the kingpin to clear the fifth wheel (about 12 to 18 inches). NOTE Do not drive tractor free of trailer. 8.
DRIVING - Fifth Wheel 1. WARNING DO NOT move the fifth wheel while the tractor-trailer is in motion. Your load could shift suddenly, causing you to lose control of the vehicle. Never operate the vehicle with the switch in the UNLOCK position. Always inspect the fifth wheel after you lock the switch to be sure the fifth wheel slide lock is engaged. Failure to comply may result in death, personal injury, equipment or property damage.
DRIVING - Driving Tips and Techniques WARNING Do not operate the vehicle unless the locking plungers are fully inserted into the fifth wheel slide track. Operating the vehicle while the plungers are not fully inserted could lead to the slide moving unexpectedly, resulting in a loss of vehicle control and potentially causing property damage, serious injury, or death. 9. 10. If the landing gear was lowered, raise the landing gear.
DRIVING - Driving Tips and Techniques Descending a Grade WARNING 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. To reduce the risk of an accident which could cause death or personal injury, before going down a steep or long grade, reduce speed and shift the transmission into a lower gear to help control your vehicle speed.
DRIVING - Stopping the Vehicle WARNING DO NOT look at the Instrument Cluster Display for prolonged periods while the vehicle is moving. Only glance at the monitor briefly while driving. Failure to do so can result in the driver not being attentive to the vehicle’s road position or situation, which could lead to an accident and possible death, personal injury, or equipment damage. The digital display provides information to help the driver optimize vehicle efficiency.
DRIVING - Stopping the Vehicle Turbocharger 4 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.
DRIVING - Antilock Brake Systems (ABS) WARNING Lift axles that are not equipped with parking brakes should be fully raised when parking the vehicle. Lift axles, that are not equipped with parking brakes, left in the down position while parked, in certain cases, could cause the parked vehicle to roll, causing an accident involving death or personal injury. 1. Set the parking brake before leaving the driver’s seat.
DRIVING - Antilock Brake Systems (ABS) WARNING The antilock 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 inproperty damage, personal injury, or death.
