DRIVING - Driver Assistance vehicle for more detailed description of functionality and warnings. Driver Assistance 4 Driver Assistance (or Advanced Driverassistance Systems (ADAS)) defines a variety of electronic features which assist the operator while driving. These features use automated technology to improve operator and vehicle safety by alerting the operator (and in some cases taking actions) to the driving environment.
DRIVING - Driver Assistance engine manual included with your vehicle. This vehicle's electronic system will perform a ‘rationality check’ every time the vehicle is started. This check is to ensure that the service brakes are working before allowing cruise control to function. This safety feature is designed to ensure that a driver is able to cancel the cruise set speed by using the service brake pedal. The system will not allow cruise control operation if it does not pass the ‘rationality check.
DRIVING - Driver Assistance more information see Cruise Control on page 142. How to Use Set Cruise Control Speed When Driving 4 These instructions DO NOT apply to Adaptive Cruise Control. While the buttons are also used to control PTO operations, these instructions are specifically for vehicle speed.
DRIVING - Driver Assistance including ignoring further input from the accelerator pedal, but will only use engine braking if available and enabled. VRSL replaces the Cruise Control indicator when active and will show the VRSL limit to the right of the indicator. This limit is shown in gray but turns white when actively limiting vehicle speed. MX engines, additionally, show "LIMITED" on the speedometer.
DRIVING - Driver Assistance Adaptive Cruise Display WARNING Driver Assistance features respond differently to specific road, weather, and traffic conditions. The operator must read the ADAS operator’s manual associated with this feature and understand how it responds to these specific conditions prior to driving the vehicle. Failure to do so may result in death, personal injury, or property damage.
DRIVING - Driver Assistance Following Distance Alerts The display will be white when the tracked vehicle in front is at a proper following distance. If the following distance decreases (less than 1.5 seconds), the following distance bars will turn amber. When the following distance decrease more (0.5 seconds), the following distance bars will turn red.
DRIVING - Driver Assistance Mitigation will apply the service brakes and present the following warning in the Driver Assistance area of the display (see Minimized View with Driver Assistance) along with an audible warning: BRAKE 4 Additionally, this popup will appear instructing the operator to take control: Collision Mitigation should not be used to stop or slow the vehicle without operator intervention.
DRIVING - Driver Assistance NOTE Adaptive Cruise Control (ACC) has the ability to override Eco cruise. This is because ACC is designed to decelerate the vehicle to match the speed of traffic in front of the ACC equipped truck. PCC Behavior As the vehicle approaches the top of a hill, PCC will decrease the vehicle speed (up to 8%below the set speed) to prevent the vehicle from exceeding the set speed while traveling downhill.
DRIVING - Driver Assistance position, etc. To effectively diagnose and clear the fault codes, the truck must be taken to your local dealership. Fuel Economy Savings Not Achieved 4 PCC Controls Lane Departure Warning (LDW) PCC uses the same buttons as Cruise Control. See Cruise Control on page 142.

DRIVING - Driver Assistance • WARNING Driver Assistance features respond differently to specific road, weather, and traffic conditions. The operator must read the ADAS operator’s manual associated with this feature and understand how it responds to these specific conditions prior to driving the vehicle. Failure to do so may result in death, personal injury, or property damage.
DRIVING - Driver Assistance the use of the turn signal. A lane departure event is accompanied by an audible alert. Lane Departure Active Warning Left the driver at all times. Failure to do so may result in death, personal injury, or property damage. WARNING 4 The LDW feature provides audible and visual alerts only and does not attempt to correct the vehicle’s position in the lane.
DRIVING - Transmission highway departure prior to the braking action taken during a HDB event (see Lane Departure Warning). The operator can acknowledge and cancel a Highway Departure Braking (HDB) event by • Applying the service brake and braking more than that applied by HDB. • Pressing the accelerator pedal and pressing more than 90% of the pedal range. • Activating the turn signal. • Activating the hazards. • Steering the vehicle back into the lane.
DRIVING - Transmission also requires that you adjust the engine rpm in the middle of the shift which ultimately synchronizes the gears during shifting. Synchronizing reduces wear on the gears. Operating Manual Transmissions 4 The transmission shift pattern for your vehicle may be located on the shift control knob. In addition to understanding the shift pattern and its location, you should read the transmission manufacturer’s manual provided with your vehicle before operating the vehicle.
DRIVING - Transmission • • • • Always select a starting gear that will provide sufficient gear reduction for the load and terrain. 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. How to Use the Hydraulic Clutch CAUTION DO NOT push the clutch pedal completely to the floor when shifting while the vehicle is in motion.
DRIVING - Transmission 4 match your vehicle's engine speed with driveline speed to achieve clash-free shifts. The manual transmission in your vehicle is not equipped with gear synchronizers. Whether you are upshifting or downshifting, it is best to double clutch. To double clutch: 1. Push the clutch pedal down to disengage the clutch. 2. Move the gear shift lever to neutral. 3. Release the pedal to engage the clutch.
DRIVING - Transmission included with your vehicle for instructions on how to change shift configurations. Transmission Gear Display Gear Display Icon (gear number) This indicator will show the transmission mode and current gear.. This does not apply to vehicles with Allison Automatic transmissions.

If the prompt appears in the instrument cluster, use the manual gear selector lever to change gears. Drive Neutral Reverse Selector Gear Display Icon (Gear shift assist) The instrument cluster will illuminate with the corresponding gear.
DRIVING - Transmission Auto Neutral Gear Display Icon (Auto Neutral) select when it is necessary to engage a gear. The transmission will exit Neutral Coast Mode and reengage an appropriate gear under any of the following conditions: • AN The Auto Neutral feature will automatically shift to Neutral if the vehicle is left in forward or reverse mode and the parking brake is set. The driver must then select the desired forward or reverse mode with the service brake applied.
DRIVING - Brakes Automatic Transmissions An automatic 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 transmission included with your vehicle. WARNING 4 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.
DRIVING - Brakes Parking Brake 1 2 3 1. 2. 3. Normal run position Trailer park with vehicle released System park or trailer charge with vehicle parked Parking brakes work in reverse action of the regular brakes. When the parking brakes are engaged, air is exhausted from the spring chambers, which allows the spring to engage the brakes. This design also provides a safety function if a brake Y53-6110-1A1 (01/21) circuit has a leak and loses air. In such a scenario, the parking brakes will apply.
DRIVING - Brakes 4 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. For detailed system description, see literature for your specific ABS that was provided with your vehicle.
DRIVING - Brakes NOTE Tractors/Trucks and trailers built after 03/01/2001 must be able to turn on an In-Cab Trailer ABS Warning Light (per U.S. FMVSS121). The industry chose Power Line Communication (PLC) as the standard method to turn it on. On trailers built prior to 03/01/2001 verify trailer ABS system status via the required external warning light mounted on the trailer. The indicator light on the trailer should be yellow and identified with the letters ABS.
DRIVING - Brakes A Real World Example of How the System Operates 4 Electronic Stability Control 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.
DRIVING - Brakes appropriate path of travel. For example, in an over-steer situation, the system applies the "outside" front brake; while in an understeer condition, the "inside" rear brake is applied. Automatic Traction Control A Real World Example of How Yaw Control Operates Your truck/tractor ABS has an automatic traction control (ATC) feature. This feature is controlled by a switch. This feature is monitored by a warning lamp located on the switch.
DRIVING - Brakes spin. When this function is in use, the ATC Warning Lamp blinks continuously. Off-Road ABS Function Switch (Optional) 4 Your vehicle may be equipped with a separate switch to activate an Off-Road ABS function. This function is NOT to be used for On-Highway driving but is intended to be used to improve stopping performance in Off-Highway conditions (e.g., loose gravel and mud).
DRIVING - Brakes • WARNING Exercise extreme care when towing doubles or triples with a vehicle equipped with Electronic Stability Program. Excessive speed and aggressive maneuvers, such as sharp turns, sudden steering inputs or abrupt lane changes should be avoided because these maneuvers could cause loss of vehicle control possibly resulting in an accident involving death or personal injury.
DRIVING - Brakes 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.
DRIVING - Brakes • Loads must be properly secured and evenly distributed at all times.
DRIVING - Axle and Suspension WARNING DO NOT use the vehicle’s engine compression brake or exhaust brake in any situation that requires an immediate stop and/or in situations of poor traction (such as wet, icy, or snow covered roads). Trying to use the engine compression brake or exhaust brake instead of the service brakes may cause a loss of vehicle control, which may result in an accident involving death or personal injury. 4 WARNING The service brakes must be used in an emergency.
DRIVING - Axle and Suspension 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. In certain situations, engaging the interaxle differential lock relieves stress on the rear axles and reduces tire wear. Engaging this switch will also provide better traction in slippery or loose gravel conditions.
DRIVING - Axle and Suspension WARNING Never shift the axle when moving downhill. Engine driveline disengagement may occur, eliminating engine retardation and allowing the wheels to spin faster than the current speed of the engine. This may require severe braking to slow the vehicle down and can result in an accident. Failure to comply may result in death, personal injury, equipment or property damage.
DRIVING - Axle and Suspension 3. 4. To make the axle downshift, release and depress the accelerator quickly to increase the engine rpm. The axle will shift to LOW range. You are now in the LOW axle range for rough terrain and heavy loads. Shift the transmission normally to maintain the desired speed.
DRIVING - Axle and Suspension 4 decrease load on the drive axles and will decrease traction. Decreasing pressure will transfer more weight to the drive axles and will result in more traction from the drive axles. Deflate the auxiliary axle suspension before coupling or uncoupling a trailer. After the trailer is coupled or uncoupled, then increase pressure to balance traction and axle load requirements.
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 - Trailer Operations 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 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.
DRIVING - Trailer Operations WARNING Always inspect the fifth wheel for proper locking after coupling the tractor to a trailer. Failure to properly couple the tractor to a trailer (the kingpin is engaged in a closed lock jaw with the lock jaw secured by a closed plunger) may cause trailer separation which could result in an accident involving death or personal injury. To lock the fifth wheel around the kingpin: Ensure trailer brakes are locked 1. and the landing gear is down. 2.
DRIVING - Trailer Operations NOTE Do not drive tractor free of trailer. 7. 4 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 - Driving Tips and Techniques 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. You could lose control of the vehicle which can lead to an accident involving death or personal injury. Do not coast with the transmission in neutral or with the clutch pedal depressed.
DRIVING - Driving Tips and Techniques 4 higher gear to bring engine rpm within the optimum speed range. When driving downhill: shift to a • lower gear, use the engine brake (if so equipped), and use the service brake, keeping the engine speed below 2,100 rpm. When the engine speed reaches its maximum governed speed, the injection pump governor cuts off fuel to the engine.
DRIVING - What to Consider when using a Sleeper Bunk General Condition Other factors affecting fuel consumption are related to loads and the type of roads on which the vehicle operates. It is not always possible to choose the most adequate road, but the ideal road is the one that allows a steady speed in high gear, without requiring frequent braking and acceleration.
DRIVING - Stopping the Vehicle WARNING Be sure no one ever rides in the upper bunk. That person could be thrown out in an accident and could be very seriously injured. The upper bunk is not equipped with a restraint system. DO NOT use the upper bunk while you are moving. Failure to comply may result in death, personal injury, equipment or property damage. 4 The sleeper restraint is stored in a compartment on the rear sleeper cab wall.
DRIVING - Stopping the Vehicle WARNING DO NOT carry additional fuel containers in your vehicle. Fuel containers, either full or empty, may leak, explode, and cause or feed a fire. Failure to comply may result in death or personal injury. WARNING Diesel fuel in the presence of an ignition source could cause an explosion. A mixture of gasoline or alcohol with diesel fuel increases this risk of explosion. DO NOT remove a fuel tank cap near an open flame.
