Riding without a safety belt which is properly fastened can lead to increased injury or death in an accident. Unbelted riders could be thrown into the windshield or other parts of the cab or could be thrown out of the cab. They could strike another person. Injuries can be much worse when riders are unbelted.
Operating Instructions Seats • Belts should fit snugly across the pelvis and chest. Make sure any slack is wound up on the retractor. To unfasten the belt: Push in the release button on the buckle. The belt will spring out of the buckle. • To release a locked belt, lean back to take the body pressure off of the belt. • To store a lap-shoulder belt, allow the belt to wind up on the retractor by guiding the belt tongue until the belt comes to a stop. 01888 Proper Safety Belt Adjustment 3.
Seats Operating Instructions Lap Belt Shoulder Belt Too High on Hips Correct Incorrect Correct (over arm) Incorrect (under arm) Incorrect (twisted) Safety Restraint Belts • Be sure, also, that your belt is not too loose. A loose belt could allow you to slide under it in an accident, and that could bring the belt up around your abdomen. • Do not twist the belt in the process of putting it on. A twisted belt will not work as well to protect you.
Operating Instructions Seats WARNING! Do not wear the shoulder belt under your arm or otherwise out of position. In a crash your body would move too far forward, increasing the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as your shoulder bones, and could cause you to suffer internal injuries. Wear the shoulder belt over your shoulder (see “Safety Restraint Belts” on page 44). WARNING! Do not twist the belt in the process of putting it on.
Seats Operating Instructions WARNING! Do not remove, modify, or replace the tether belt system with a different tether system. A failed or missing tether belt could allow the seat base to fully extend in the event of an accident leading to greater injuries or death. • Make sure the belt of the unoccupied passenger seat is fully wound up on its retractor, so that the belt tongue is in its stowed position. This reduces the possibility of the tongue becoming a striking object in case of a sudden stop.
Operating Instructions Seats Komfort–Lok® Latch 5. When you want to get out of the cab, release the latch, then just push the button on the buckle.

They include a “DON'T SHIFT” light, plus diagnostic codes that appear in the digital display on the shift control unit, audible alarms that sound, and connections for hooking up a data reader (for service only). The “DON'T SHIFT” light (located on the dash) will come ON when the engine is first started, then go OFF after a few seconds.
Using the Brake System Operating Instructions USING THE BRAKE SYSTEM NOTE: Today’s diesel engines have significant torque and startability power at low RPMs. Combinations of engine speed and available torque may overpower the vehicle’s parking brakes. WARNING! Never drive your vehicle with the parking brakes applied. Always release the parking brakes prior to moving the vehicle.
Operating Instructions Using the Brake System 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.
Using the Brake System Operating Instructions Using the Parking Brake Before you leave the cab: The yellow diamond-shaped knob on the dash controls the truck/tractor parking brakes. These are spring brakes that you activate by releasing air pressure from their chambers. When they are not in use, air pressure compresses the springs and releases the brakes. Pulling the knob OUT applies the parking brake, which exhausts air from the chambers and allows the springs to extend and apply the brakes.
Operating Instructions Using the Brake System To release the trailer brakes ONLY: (2) Trailer Air Supply Control (Red) (1) Parking Brake Control (Yellow) • Push IN the Red knob on the dash. The truck or tractor will remain parked. To release the full combination of brakes: 02394 • Push IN BOTH knobs on the dash.
Using the Brake System Operating Instructions WARNING! If the air pressure falls below 60 psi (414 kPa) the spring brakes may stop the vehicle abruptly, which could result in an accident and/or injuries. 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. WARNING! Do not use the trailer hand brake or service brakes to park and hold an unattended vehicle—use the parking brakes.
Operating Instructions Using the Brake System The parking brakes act on the rear wheels only. They are spring-applied, with air pressure used to release them. Release air is supplied by both the front and rear circuit reservoirs through a double check valve.
Using the Brake System Operating Instructions WARNING! Do not use the trailer hand brake or service brakes to park and hold an unattended vehicle—use the parking brakes. Because service brakes work with air pressure, these brakes could slowly release. Your vehicle could roll, causing a serious accident. Someone could be hurt or killed. Never rely on the service brakes to hold a parked vehicle.
Operating Instructions Using the Brake System Front Brakes — Truck The following applies to full truck configurations: If air pressure is lost in the front circuit, the vehicle front brakes will not operate. Check valves isolate the rear circuit, so the rear service brakes and parking brakes are unaffected. The spring brakes will not automatically apply as long as rear service pressure is maintained.
Using the Brake System Operating Instructions Brakes — Tractor/Trailer The following applies to tractor/trailer configurations: If pressure is lost in the tractor front or rear circuit, the “check” valves isolate the unaffected circuit, allowing this circuit to continue normal operation. The trailer brakes are still functional.
Operating Instructions Using the Brake System To prevent drums from distortion while they cool down: • Park the vehicle on level surface and block the wheels. • Release the parking brake and allow the brakes to cool down. See page 72. ABS lamp will remain on until a speed of no more than 9 mph has been reached and the speed sensors have been checked for correct output. The lamp should remain off after this point unless a failure in the system is detected.
Using the Brake System Operating Instructions Trailer ABS Warning Lamp Trucks, tractors, and trailers built on and after March 1, 2001 are equipped with power line communication (PLC) per U.S. FMVSS 121, including a trailer ABS warning lamp in the cab. A trailer ABS warning lamp will illuminate for a bulb check when the ignition switch is first turned on - whether or not a trailer is connected to the vehicle. If the bulb check is satisfactory, the lamp will next do either of the following: 1.
Operating Instructions Using the Brake System • If a trailer ABS problem is detected, the lamp will remain on. The dr iver should have the trailer’s ABS problem corrected before the vehicle is driven with that trailer attached. WARNING! Do not rely on an anti-lock brake system that is functioning improperly. You could lose control of the vehicle resulting in a severe accident and serious personal injury.
Using the Brake System Operating Instructions To operate the trailer brake hand valve: Do not use the engine retarder (such as an exhaust brake) to slow the vehicle down when you are bobtailing or pulling an empty trailer. • Pull down on the lever. • The valve is self-returning. When pressure is removed from the valve lever, it will return to the OFF position. WARNING! Do not use an engine retarder when you are driving bobtail or with an unloaded trailer.
Operating Instructions Using the Brake System WARNING! The service brakes must be used in an emergency. The engine or retarder alone might not stop you fast enough to prevent an accident. You could be badly hurt if you relied only on the engine retarder. On tractors that do not have anti-lock brake systems (ABS) a bobtail brake proportioning system is installed.
Using the Brake System Operating Instructions • After the engine is started, warmed up, and you are ready to get under way, turn the exhaust brake switch ON for added braking effect. WARNING! Do not use the engine retarder when operating on road surfaces with poor traction (such as wet, icy, or snow covered roads or gravel). Retarders can cause the wheels to skid on a slippery surface. You could lose control of the vehicle and/or jackknife if the wheels begin to skid, resulting in an accident.
Operating Instructions Using the Brake System The wet tank receives air from the air dryer and cools it somewhat, allowing moisture to condense for draining. Relatively dry air is then supplied to the two service tanks for distribution to their respective brake circuits. The service tanks are isolated from each other by check valves. Dual Service Brake Treadle Valve: delivers air to the two service brake circuits.
Using the Brake System Operating Instructions 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. Trailer Supply Valve (tractor): The Red octagonal-shaped knob protects the tractor system; it functions in conjunction with the parking brake valve (yellow).
Operating Instructions Using the Brake System Brake Components The following is a brief description of the hydraulic brake system. It is intended to supply you with general information on how the system works. For complete information see the Peterbilt Medium Duty Maintenance Manual. Anti-Lock Brake System (ABS) Modulator Valve Body: adjusts brake fluid flow between the master cylinder and the wheel calipers to avoid wheel lockup.
Using the Brake System Operating Instructions 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. Power Steering Flow Switch: senses flow of power steering fluid. Power Steering Fluid Reservoir: stores power steering fluid and offers a place to replenish when needed.
Operating Instructions Using the Brake System 1. Slow down carefully. unevenly, or to grab. These conditions can cause a lack of braking power, wheel lockups, or pulling of the vehicle to one side or the other. Here are some things you can do to assist in slowing the vehicle: Avoid driving through deep puddles or flowing water if possible. If not possible, you should to the following: • Downshift - Putting the transmission into a lower gear will help slow the vehicle. • Slow down.
Using the Brake System Operating Instructions WARNING! Do not replace wheels or tires with a different size than originally installed. The AntiLock Brake System (ABS) is calibrated for the specific tire revolutions per mile. Use of a different tire and/or wheel size may cause the ABS system to not function during a hard braking event. This could cause an accident or serious personal injury.
Operating Instructions Using the Brake System For proper ABS operation all tire sizes must be within the appropriate range (see page 182). A change of tire size may require that the ABS ECU be changed based on the listed range of compatible tire revolutions per mile (RPM). Consult your Peterbilt dealer before using a different tire and/or wheel size. MIRROR HEAT 0 OIL ! Parking Brake Burnishing LOW WATER This procedure is recommended for new vehicles where less lever actuation force is required.
Using the Brake System Operating Instructions 3. After stopping, release the parking brake lever and drive the vehicle at 20 mph (32 km/h) in a low gear for approximately 2.5 miles, to allow the brake drum to cool. 4. Repeat steps 1, 2, and 3 above until a total of 10 stops have been completed. 5. Adjust the parking brake lever. See the Medium Duty Maintenance Manual.
Operating Instructions Operating the Rear/Drive Axle OPERATING THE REAR/DRIVE AXLE When operating normally on paved, dry surfaces, keep your truck's interaxle differential in the UNLOCK position. Introduction GUARD This section covers the operation of your Rear/Drive Axle. These instructions apply to the most common features of drive axles. Refer to the manufacturer’s instructions for further information on the operation of your axle.
Operating the Rear/Drive Axle Operating Instructions In the LOCK position, an air operated clutch positively locks both sets of axles together, providing greater traction on slippery road surfaces; however, steering around corners and on dry pavement is more difficult. Continuous operation on a paved, dry surface stresses the tandem axles, possibly causing internal damage. Use this feature only when driving on surfaces with poor traction, such as wet slippery roads, heavy mud or snow, or loose gravel.
Operating Instructions Operating the Rear/Drive Axle going down steep grades or traveling faster than 25 mph, or while wheels are spinning or traction is minimal; lock it before you encounter these conditions. 3. If you LOCK or UNLOCK the inter-axle differential while moving, let up momentarily on the accelerator pedal to relieve torque on the gearing and allow full engagement of the clutch (the mechanism that locks the wheels).

Close valve and run engine until smooth idle is established, then repeat drain procedures, or B.
Engine Maintenance Preventive Maintenance Accessory Drive Belts You can extend the reliability and service life of your vehicle’s drive belts with proper attention to installation, adjustment, 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. So, it is a good idea to check the belts frequently and replace them as soon as you detect trouble.
Preventive Maintenance Engine Maintenance Engine Fan Thermatic (Clutch) — Type Fan WARNING! Do not work on the fan with the engine running. The engine fan can engage at any time without warning. Anyone near the fan when it turns on could be seriously injured. Before turning on the ignition, be sure that no one is near the fan. To Check the Fan: 02953 Tension Test Retensioning New Belts A belt is considered “used” after 30 minutes of operation. After running for an hour or more, new belts will loosen.
Engine Maintenance Preventive Maintenance • The leading edge of any fan blade must be 1 in. (25 mm) from the inside edge of the shroud. Fan Drive and Blade Fan Blade Clearance: Around the fan shroud, the recommended distance is 1 in. (25 mm) from front edge of any fan blade-to-radiator side member. Minimum clearance is 3/4 in. (19 mm). • Rear edge of any blade must be no closer than 3/8 in. (9 mm) to the nearest engine component. If this cannot be obtained, the fan spacer or fan is not correct.

Cooling System Preventive Maintenance concentration and corrosion inhibitor content as the original coolant in the cooling system. Never add 100% antifreeze to the cooling system. Always dilute antifreeze to the correct concentration based on freeze protection prior to adding it to the cooling system. Adding or using 100% antifreeze in a cooling system may result in cooling system plugging and overheating problems.
Preventive Maintenance Table 7 Cooling System Cooling System Maintenance and Schedule DAILY or as REQUIRED 15,000 MILES (24,000 km) SPRING and FALL (BIANNUAL) With the engine off and temperature cool: WARNING! Do not remove the radiator cap on a hot engine. It can cause scalding coolant to spray out and you could be burned. If the engine has been operated within the last 30 minutes, be very careful in removing the radiator cap. With the engine off and temperature cool: Clean Cooling System. 1.
Cooling System Preventive Maintenance Adding Coolant ant conditioner manufacturer recommendations. A mixture of water and low silicate antifreeze should be used for coolant. Water must be clean and free of corrosive and scale-forming chemicals. Drinking water may not be good for your vehicle. New vehicles come premixed with antifreeze and corrosion inhibitor. Be sure different types of coolant are not mixed. Stay with the same coolant until a complete replacement is performed.
Preventive Maintenance Cooling System NOTE: Avoid using a hydrometer for measuring freeze point. Hydrometers have poor accuracy. Use a Glycol Refractometer for checking antifreeze protection. A 50/50 mixture (50% water and 50% low silicate antifreeze) is best for year-round normal operation. This will normally protect your engine from freezing and boil-over. Table 8 Always use low silicate antifreeze with water. Premix the coolant to maintain the correct proportion of antifreeze and water.
Cooling System Preventive Maintenance • Replace the filters • Refill with premixed coolant. Consult the Medium Duty Maintenance Manual for the correct filters to install. • Antifreeze solutions containing anti-leak additives will quickly restrict the water filter. If this happens, the filter will not work. So stay away from anti-leak additives.
Preventive Maintenance Cooling System CAUTION: Do not overfill the cooling system. When hot, it could overflow, resulting in loss of c o o la nt , re d uc ed co o li n g p ro te ct i on , a n d reduced corrosion-inhibitor protection. Table 9 You may find the coolant level is not up to the correct level soon after you have filled the radiator. This may be because all the trapped air in the system has not yet been purged.
