PART 1: INTRODUCTION

This manual contains useful information for the safe and efficient

operation of your Peterbilt Model 387 vehicle. It also provides information on maintaining your vehicle in the best condition, with an outline for performing safety checks and basic preventive maintenance inspections.

We have tried to present the information you’ll need to learn about your vehicle’s fu nctions, controls, and operation - and to present it as clearly as possible. We hope you’ll find this manual easy to use.

Please remember, though -- this manual is not a training manual. It can’t tell you everything you need to know about driving your Peterbilt vehicle. For that you need a good training program or truck driving school. If you have not been trained, get the proper training before you drive. Only qualified drivers should drive this vehicle.

There will be times when you need to take this manual out of your Peterbilt. When you do, please be sure to return it to the cab when you are finished using it. That way it will be there when you need it the next time or when you pass the vehicle on to the next user.

How to Find What You Want

There are several tools built into this manual to help you find what y ou need quickly and easily.

A Special Word about Repairs

Your Peterbilt dealer’s service center is the bes t place to have your vehicle repaired. You can find Peterbilt dealers all over the country with the equipment and trained personnel to get you back on the road quickly - and keep you there.

Your vehicle is a complex machine. Anyone attempting repairs on it needs good mechani cal training and the proper tools. If you are sure you have these requirements, then you can probably perform some repairs yourself. However, all warranty repairs must be performed by an authorized Peterbilt service facility. If you aren’t an experienced

mechanic, or don’t have the r ight equipm ent, plea se leave all repairs to an authorized service facility. They are the ones equipped to do the job safely and correctly.

WARNI NG! Attempting repair work without sufficient training, service manuals, and the proper tools can be dangerous. You could be injured or you could make your truck unsafe. Do only those tasks you are fully qualifie d to do.

Maintenance Manuals. If you do decide to do any complex repair

work, you’ll need the Peterbilt Maintenance manuals. Order them from your authorized dealer. Please provide your Chassis Serial Number when you order, to be sure you get the correct manuals for your vehicle. Allow about four weeks for delivery. There will be a charge for these manuals.

Final Chassis Bill of Material. A complete, nonillustrated computer printout listing of the parts used to cust om -build your Peterbilt vehicle is available through the Peterbilt dealer from whom your p urchased your vehicle.

WARNI NG! Modifying your vehicle can make it unsafe.

Some modifications can affect your truck’s electrical system, stability, or other important functions. Before modifying your vehicle, check with your dealer to make sure it can be done safely.

Additional Sources of Information

Operator’s manuals are also s upplied by the manuf act urers of components such as the engine, seats, transmission, and radio in your Peterbilt. If you are missing any of thes e manuals, ask your Peterbilt dealer to supply them.

Your Model 387’s glove box also contains a copy of the Truck

Driver’s Handbook, published by the American T rucking Association. Refer to it for imp ortant information on driving your vehicle. Another place to learn more about trucking is a local truck driving school. Contact one near you to find out what kinds of instruction it offers.

Federal and state agencies also have information you can ask for. The Interstate Commerce Commission can give you information about regulations governing transportation across state lines. And various agencies in state governments are sources for regulations that differ from state to state.

PART 5: SEAT AND RESTRAINT SYSTEMS

Seat

For information on the features and adjustment of the seat, see the seat manufacturer’s literature included with the vehicle.

WARNI NG! Do not drive or ride with your seat back in the reclined position. You could be injured by sliding under the seat belts in a collision.

WARNING! Do not adjust the driver’s seat while the vehicle is moving. The seat could move suddenly and unexpectedly and can cause you to lose control of the vehicle. Make all adjustments to the seat while the vehicle is stopped. After adjusting the seat and before driving off, ensure that the seat is firmly latched in position.

Seat Belts And Their Proper Use

Seat (or safety) belts have proven to be the single most effective means available for reduc ing the risk of serious injury and deat h in motor vehicle accidents. It’s not jus t an opinion -- it’s a fact: Seat belts save lives.

WARNING! Do not drive vehicle without your seat belt

and your riders’ belt fastened. Riding without a safety belt properly fastened can lead to increased injury or death in an emergency. 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. Always fasten your seat belt

Shoulder Belt

Your combination shoulder-lap belt needs proper adjustment:

• The lap portion should be worn as low on the hips as possible.

Properly worn belt Improperly worn belt

WARNING! You can be seriously injured if your belt is buckled too high. In a crash, it would apply force to your abdomen, not your pelvic bones. This could cause serious internal injuries. Always wear your seat belt low over your pelvic bones.

• The shoulder portion should fit snugly across your body. It should

always be worn over the shoulder next to the door. It you put the

belt under your arm, it can’t protect you properly.

PB1328 —51— 22-02011 (R02/02)

PART 5: SEAT AND RESTRAINT SYSTEMS

WARNI NG! Wearing the shoulder belt under your arm could lead to serious injury. In a crash your body would move too far forward, increasing the chance of head and neck injury. And the belt would apply too much force to

the ribs, which aren’t as strong as your shoulder bones. You could also suffer internal injuries. Wear the shoulder belt over your shoulder.

• 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.

WARNING! A too-loose seat belt can lead to injury in a crash. It can allow you to fall too far forward, possibly causing head and neck injuries. You could strike the wheel or the windshield. Adjust your belt so that there is no more than one inch (25 mm) of slack.

• Watch t hat you don’t twist the belt in the process of putting it on. A

twisted belt won’t work as well to protect you.

02930

Twisted Belt

WARNING! You could be seriously injured by a twisted belt. In a crash, the full width of the belt wouldn’t be pro t ectin g you. And the twist ed belt could cut in t o your body . Straighten the belt before buckling it. If you can’t, have your dealer or service person fix it.

To connect your shoulder-lap belt: Grasp the belt tongue and pul l in a smooth, slow motion across your chest and lap. Insert the tongue into the buckle on the inboard side of the seat. Push down until you hear a click. Pull on the belt to make sure it is buckled. Check that it is positioned correctly on your body.

PB1328 —52— 22-02011 (R02/02)

PART 5: SEAT AND RESTRAINT SYSTEMS

Comfort Feature

Your Peterbilt contains a feature des igned to eliminate cinching an d 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 featu re increases with rou gh road conditions, particularly over long distances.

To eliminate cinching simply activate the comfort feature at the appropriate ti me:

1. Fasten your seat belt according to the directions given earlier.

2. Lean forward to pull a little slack (about 1 inch) in the belt. Be sure to allow only a small amount of slack. See the Warning on a loose belt, on the previous page.

3. When the slack is right, slide the comfort feature up the belt until it engages the D-loop.

4. To release the comfort feature, reach up and pull it down along the belt until it no longer engages the D-loop.

5. When you want to get out of the cab, release the comfort feature, then just push the button on the buckle.

Pregnant Women: Sometimes pregnant women worry that in a crash the seat belt could hurt the baby. But if a woman wears her belt prop-

erly - low over her pelvis, below he r abdomen - the belt w on’t harm the baby, even in a crash. And remember - t he best way to keep an unborn baby safe is to keep the mother safe.

PART 5: SEAT AND RESTRAINT SYSTEMS

the opening. Of course, you do not need to use a restraint if you sleep in a parked vehicle. But anyone using the sleeper while the truck is in motion should be restrained in a safety device.

CAUTION: To avoid damage when lifting a bunk, remove all items from the top of the bunk mattress, and arrange bedding so that items will not slide down the mattress and fall behind the bunk .

The bunk restraint is attached to the sleeper in six locations (see illustration below):

1. Two buckles at the upper rear wall

2. Two buckles at the side walls

3. Bolts in two places at the lower rear wall

There is also a buckle at the driver ’s side front of the bunk ( ) for easy entry/exit of the sleeper with the bunk restraint in use.

• The upper rear wall: Access to the bunk is easiest when these

connections are buckled and the front buckle is detached.

• The side walls: The tenting straps are attached to the side wall

sills with easy-to-use buckles.

• The lower rear wall: The restraint is attached to the lower rear wall

by bolts that do not require removal for use or stowage of the bunk restraint.

PB1328 —54— 22-02011 (R02/02)

PART 5: SEAT AND RESTRAINT SYSTEMS

You will notice that if your Peterbilt has an upper bunk, it has no restraint device. This is becaus e no one should ev er be in an up per bunk when the vehicle is moving.

WARNI NG!

•

In an accident an unrestrained person lying in a sleeper bunk could be seriously injured. He or she could be thrown from the bunk. Be sure anyone occupyi ng the sleeper is restrained whi le the vehicle is moving.

•

Be sure that no one ever rides in the upper bunk. That person would be thrown out in an accident and could be very seriously injured.

Passengers

Anyone riding in your vehicle should wear a seat belt. The responsible operator sees t o it that everyon e in the vehicle ri des safely - an d that means with a seat belt.

Some Oth er Safety Restr ai n t T ips:

Don’t wear belts over rigid or breakable objects in or on your cloth-

•

ing. Such things might be eyeglasses, pens, keys, etc. These could cause injury in an accident.

• Damaged belts in the cab or sleeper must be replaced. Belts that

have been stretched, cut, or worn out may not protect you in an accident.

• Avoid catching belts in the doors or seat hardware; they could be

damaged.

• Don’t modify or disassemble the seat belts in your vehicle. They

won’t be available to keep you and your passengers safe.

• Nev er bleach or dye seat belts; chemicals can weaken them. Do,

however, keep them clean by following the care label on the belts. Let them dry completely before allowing them to retract.

• If any seat belt is not working properly, see an authorized Peterbilt

dealer for repair or replacement.

PB1328 —55— 22-02011 (R02/02)

PART 5: SEAT AND RESTRAINT SYSTEMS

Tether Belts

Tether belts are installed on suspensi on seats. They help sec ure th e seat to the floor to restrain it in case of a sudden stop or an accident.

WARNING! Do not remove, modify, or replace the tether belt system with a different tether system. A failed or missing tether belt could allow a seat base to fully extend in the event of an accident leading to greater injuries or death.

Tether Adjustment

WARNI NG! Failure to adjust tether belts properly can cause excessive movement of the seat in an accident. This could lead to greater injuries for you. Tether belts should be adjusted so that they are taut when the seat is in its most upward and forward position.

WARNING! Before driving or riding in a vehicle, ensure that there is adequate head clearance at maximum upward travel of seat. Serious injury may occur if head clearance is not adequate. Shorten the tether belt as necessary to provide adequate head clearance.

• Make sure the tether belt is attached to the cab deck and seat

frame. It should be routed through the buckle on each side.

• To lengthen the tether, turn the buckle to a right angle to the web-

bing. Then pull the buckle. To shorten the tether, pull on the strap.

PART 5: SEAT AND RESTRAINT SYSTEMS

Inspection of the Restraint System

WARNI NG! Failure to properl y inspect and maintain restraint systems can lead to serious injury or loss of life. Without periodic inspection and maintenance to detect unsafe conditions, seat restraint components can wear out or not protect you in an accident.

The typical three-point seat systems in passenger cars may seem very similar to the three-point seat belt system in heavy duty vehicles, but there are some key differences which all users of this system should be aware of:

• In typical passenger vehicle automotive seat belt applications, the

normal life of the vehicles is usually 8 to 10 years and the total mileage frequently does not exceed 125,000 miles (200,000 km). Heavy duty vehicles often see this type of mileage in a very shor t period of time, and accumulation of mileage in excess of 500,000 miles (800,000 km) during the vehicle lifetime is not unusual.

• A significant difference in the two systems is the amount of move-

ment of webbing in the system. In an automotive application, there is little movement of the seat belt system, except when the user puts on or takes off the belt. In trucks, however, there is almost constant movement of the belt through hardware due to ride characteristics and seats which are designed to move, in order to enhance driver comfort. There can even be movement of the webbing in the seat belt system when the belt is not being used. Relative movement between the seat and the cab, which normally occurs whenever the truck is in operation, can cause wear of the seat belt webbing.

• Environmental conditions represent another major difference in

the systems in automobiles and heavy duty and specialty vehicles. Unlike the automotive environment, heavy duty and specialty vehi-

cles may be very dirty, and have more exposure to the Sun’s damaging ultraviolet rays, thus resulting in a reduction of the life of the seat belt system.

The high mileage asso ciated with heavy duty vehicles and possible wear of the 3-point seat belt system, the continual relative movement of the system, the possible contact with the vehicle seat or other parts of the cab structure, and the potential exposure of this system to severe environmental conditions make it crucial to inspect the threepoint seat belt systems regularly. It is recommended that the seat belt system in a vehicle be inspected every 20,000 miles (32,000 km) or more often if the vehicle is exposed to severe environmental conditions. Any seat belt system that shows cuts, fraying, extreme or

PB1328 —57— 22-02011 (R02/02)

PART 5: SEAT AND RESTRAINT SYSTEMS

unusual wear, significant discoloration due to UV exposure, abrasion to the seat belt webbing, or damage to the buckle, latch plate, retractor hardware or any other obvious problem should be replaced immediately, regardless of mileage.

WARNING! It is important to remember that any time a vehicle is involved in an accident, the entire seat belt system must be replaced. Unexposed damage caused by the stress of an accident could prevent the system from functioning properly the next time it is needed, which could result in severe injury or even death.

One of the most critical areas to be inspected is the seat belt webbing. Constant movement of the belt ac tually means the webbing is experiencing wear as it travels in and out of the retractor, through the pillar loop web guide and through the various pieces of hardware associated with the belt. The following guidelines detail how to inspect for cuts, fraying, extreme or unusual wear of the webbing, etc. and damage to the buckle, retractor, hardware, or other factors which indicate that belt replacement is necessary.

03004

PB1328 —58— 22-02011 (R02/02)

PART 5: SEAT AND RESTRAINT SYSTEMS

1. Check the web wear in the system. The webbing must be closely examined to determine if it is coming into contact with any sharp or rough surfaces on the seat or other parts of the cab interior. These areas are typical pl aces where the web will experi ence cutting or abrasion. Cuts, fraying, or excessive wear would indicate the need for replacement of the seat belt system.

2. The D-loop web guide is the area where almost constant movement of the seat belt webbing occurs because of relative movement between the seat and the cab.

3. Check the comfort feature for cracks or possible damage and that it works properly.

4. Check the buckle and latch for proper operation and to determine if the latch plate is worn, deformed, or damaged.

5. Inspect the retractor web storage device, that is mounted on the floor or B-pillar of the vehicle for damage. The retractor is the heart of the occupant restraint system and can often be damaged if abused, even unintentionally. Check retractor web storage device operation to ensure that it is not locked up and that it spools out and retracts webbing properly.

6. If adjustable tethers are being used, be sure they are adjusted in accordance with installation instructions. Tethers must also be inspected for web wear, just as with the seat belt systems.

7. Mounting hardware should be evaluated for corrosion, and for tightness of bolts and nuts.

8. Check web in areas exposed to ultraviolet rays from the sun. If the color of the web in these areas is gray to light brown, the physical strength of this web may have deteriorated due to exposure to the

sun’s ultraviolet rays; replace the system.

W ARNI NG! Replac e t he ent ir e belt sys t em (retr ac tor and buckle side) if replacement of any one part is necessary. Unexposed damage to one or more components could prevent the system fr om funct ioni ng properly the next time it is needed, which coul d r esu lt in se ve r e inj ury or even dea t h.

If the inspection indicates that any part of the seat belt system requires replacement, the entire system must be replaced, both retractor and buckle side. An installation guide is attached to every

SEAT BELT INSTALLATION GUIDE.”

instruction guides for suspension and fixed bench seats. Use the proper guide for your type of seat, and follow the instructions very closely. It is vitally important that all components must be remounted back in the same position as the original components that were removed. This will maintain the design integrity of the mounting points for the seat belt assembly.

Once the need for replacement of the seat belt has been determined, be certain that it is only replaced with the recomm ended replacem ent seat belt. The occupant restraint system has been developed and tested specifically for this vehicle. If the vehicle was originally equipped with a lap belt, it cannot be replaced with a three-point shoulder harness system, because the cab mount ing points are not structurally designed for a three-point seat belt.

PART 6: DRIVER’S CHECKLIST

To keep your vehicle in top shape, and to maintain its high level of safety for you, your passengers, and your load, make a thorough

inspection every day before you drive. You’ll save maintenance time later -- and the safety checks could help prevent a serious accident. Please remember, too, that Federal law requires a pre-trip inspection and so do commercial trucking companies.

For more information, you can refer to Department of Transpor tation Regulation 392.7 which tells you that interstate commercial motor vehicles are not to be driven unless the driver is sure that certain parts and accessor ies are in working order.

You aren’t expected to become a professional mechanic. The purpose of your inspections is to find anything that might interfere with the safe and efficient transportation of yourself and your load. If you do find something wrong and ca n’t fix it yourself, please have a qualified mechanic fix it right away.

Safe Vehicle Operation

For your safety, as well as those around you, be a responsible driver:

• If you drink, do not drive.

• Do not drive if you are tired, ill, or under emotional stress.

Much has gone into the manufacturing of your Peterbilt, including advanced engineering techniques, rigi d quality cont rol, and d emanding inspections. These manufacturing proces ses will be enh anced by

you—the safe driver—who observes the following:

• knows & understands how to operate a vehicle and all its controls

• maintains the vehicle properly

• uses driving skills wisely

WARNING! Do not drink and drive. Your reflexes, perceptions, an d judgmen t can be affected by even a small

amount of alcohol. You could have a serious—or even fatal accident—if you drive after drinking. Please do not drink and drive or ride with a driver who has been drinking. The use of alcohol, drugs, and certain medications will seriously impair perception, reactions, and driving ability. These circumstances can substantially increase the risk of an accident and personal injury.

The daily checks listed below are the foundation of your overall preventive maintenance program. See PART 8: MAINTENANCE AND

PART 7: STARTING & OPERATING THE VEHICLE

Since each Model 387 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.

Also check the ATA Truck Driver’s Handbook in your glove box. It will give you tips on starting, shifting, and driving a truck.

Below are instructions for both nor m al-temp erature starting and co ldweather starting.

Normal Starting Procedure (Normal Temperature)

When the outside temperature is above 50° F (10° C), you can use the following procedure.

1. Set the parking brake.

2. Put your main transmission in Neutral.

3. Disengage (depress) the clutch (with manual transmission).

4. Tur n the key switch to ON.

• If your vehicle is equipped with a digital message center (DMC),

the DMC display will come on in the “Clock” mode.

• The multipl ex instrumentation syste m wil l begin a self-te st:

-Gauge pointers will move to a 12:00 position, with their LED

warning lights on, for 5 seconds.

-Gauge pointers will then move to their actual gauge readings

and their LED warning lights will go off.

• The speedometer mes sa g e center (SMC) w ill dis play the odome -

ter.

NOTE: If the SMC displays other messages or if other alarms

activate after the key is turned ON, see the “Warning Alarms” section at the end of this part on page 96

5. Turn the key to start.

CAUTION: Never operate the starter motor while the engine is running. The starter and flywheel gears could clash or jam, severely damaging them.

NOTE: Some starters are equipped with overcrank protection. Check the “Engine Operation and Maintenance Manual” for details.

If the engine does not start within 30 seconds, release the starter but-

ton. To avoid overtaxing the start er motor or the batteries, don’t use

PB1328 —65— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

the starter for more than 30 seconds. Let the start er motor cool an d the batteries recover for 2 minutes before trying again.

If the engine still won’t star t a fter a couple of tries, check the manual override shutdown valve and fuel lines for possible fuel starvation or air leaks. Starting failure may mean fuel isn’t reaching the injectors.

6. As soon as the engine starts, begin to watch the oil pressure gauge. Check your engine manufacturer’s 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 until normal engine oil pressure registers on the gauge before idling or accelerating the engine beyond 1000 RPM.

NOTE: If your vehicle has a DDC engine, and if it has not been started for more than 30 days, squirt about half a cup (120 ml) of clean, specified engine oil into the turbocharger oil inlet port. Use an oil can. This will keep the turbocharger bearings lubricated until the engine oil pressure gets up to normal.

Cold Te m perature Starting Procedure

In cold weather, fast engine starting helps relieve the loads on the electrical system and cranking motor. Using the special cold starting equipment will help starting. If you follow a f ew simple guidelines, you will extend the service life of your engine.

•Keep the electrical system in top condition.

•Use the best quality fuel of the recommended grade.

•Use recommended engine lubricating oil.

Engine Warmup

The pur pose of engine warmup is to allow oil film to be established between pistons and liners, shafts and bearings while your engine gradually reaches operating temperature.

Warmup Procedure

1. After you’ve started your engine, idle it at approximately 600 RPM while you check

•oil pressure

•air pressure

•alternator output

PB1328 —66— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

2. After a few minutes of idling at 600 RPM, increase your idle speed to 900 or 1000 RPM. Continue your warmup. This procedure allows oil to warm and flow freely while pistons, liners, shafts, and bearings expand slowly and evenly. In extremely cold temperatures, you may have to increase idle speed.

NOTE: In colder climates where the temperature is often below freezing, the warmup for turbocharged engines is especially important. Chilled external oil lines leading to the turbocharger will slow the oil flow until the oil war m s, reducing oil available for the bearings. Watch the engine oil temperature or pressure gauge for a warming trend before increasing engine idle speed (RPM).

3. Continue the engine warmup until the coolant temperature

reaches at least 130° F (54° C). At this temperature, you can use partial throttle. Wait until the coolant temperature is at least 160° F (71° C) before operating at full throttle.

NOTE: Keep the engine exhaust system and the vehicle’s cab/ sleeper ventilation system properly maintained. It is recommended that the vehicle’s exhaust system and cab/sleeper be inspected

•

By a competent technician every 15,000 miles

•

Whenever a change is noticed in the sound of the exhaust system

•

Whenever the exhaust system, underbody, cab or sleeper is damaged

PB1328 —67— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

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 FA N SPEED. Even with the ventilation system On, running the engine while parked or stopped for prolonged periods of time is not recommended.

NOTE: If other vehicles are parked next to you idling, move your vehicl e or do not stay in your vehic le f or prolonged periods of time.

CAUTION: The use of a winterfront can result in excessive engine coolant, oil, and charge air (intake) temperatures, which can lead to overheating and possible engine dam-

age. If you must use a winterfront, refer to the “Engine Operation and Maintenance Manual” for operating r estrictions and recommendations.

Transmission Warmup

In cold weather you may find shifting sluggish when you first sta rt the engine. Transmission warmup 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 lubricating oil during engine warmup, with a single transm is sion:

• Check that the transmission is in Neutral.

• Release the clutch pedal.

If you have a two -transmissi on combination:

• Put the main transmission in gear.

• Put the auxiliary transmission in N eu t ra l. This w ill allow the trans -

mission countershaft to turn, agitating the oil and warming it.

Idling the Engine

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.

PB1328 —68— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

WARNING! To reduce the chance of personal injury and/or vehicle damage from overheated engines, which can result in a fire, never leave the engine idling without an alert driver present. If the engine should overheat, as indicated by the engine coolant temperature light, immediate action is required to correct the condition. Continued unattended operation of the engine, even for a short time, may result in

During the time it takes you to drink a cup of coffee, your engine can

serious engine damage or a fire. CAUTION: Do not allow your engine to idle, at low rpm

(400–600 rpm), longer than five minutes. Long periods of idling after the engine has reached operating temperatures can decrease engine temperature and cause gummed piston rings, clogged injectors, and possible engine damage from lack of lubrication. The normal torsional vibrations generated can also cause transmission wear.

Shifting The Transmission

You will find a shift pattern either on a decal in your cab or on a medallion in the shift knob. Check to be sure you know the correct sequence for your particular transmission. Re fer to the transmission manual included with your vehicle for complete instructions in the operation of your transmission.

Shifting Gears in a New Vehicle

Shift carefully in a new vehicle. The transmission m ay be a little stiff at first. So be careful to avoid gear clashing.

When you are operating a new vehicle or one that has been exposed to cold weather, you want the transmission lubrican t to circulate and coat the contacting surfaces of the gears. Metal contacting metal in moving parts may seriously damage your transmission. So don’t drive in one gear for long until the transmission lubricant has had a chance to coat those contacting surfaces.

PART 7: STARTING & OPERATING THE VEHICLE

Operatin g th e C l u tch

“Rid ing” th e C lutch

The clutch pedal is not a footrest. Driving with your foot on the clutch pedal will allow your clutch to slip, causing excessive heat and wear. You can damage your vehicle this way .

Clutch Travel

CAUTION: 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, other transmission components, and may cause damage.

To put your vehicle into motion, push d own on the clutch pedal until the clutch brake makes contact. This contact will occur at about 1/2 inch to 1 inch from the end of pedal stroke. Select a gear low enough to let your vehicle start forward with the throttle at idle until the clutch is fully engaged.

The total stroke of the clutch pedal is about 10 inches. The first 1 3/4 to 2 inches is free travel. After that is the release stroke, the part that fully releases the clutch. The last 1/2 to 1 inch engages the clutch brake. If your vehicle is new, watch the free travel in your clutch carefully for the first few hundred miles. As your clutch lining wears and high spot s get worn smo oth, you will get les s fre e travel.

Always start out in a low gea r with a c eramic-faced clutch. S tarting in higher gears, even with a light load, will cause a very j umpy star t an d

excessive wear. And don’t allow your vehicle to roll in the opposite direction at all during clutch eng agement. 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.

Release Bearing Wear

When you must idle your engine for any period of time, shift your transmission to neutral and engage the clutch (take your fo ot off the pedal). This helps prevent unnecessary wear of your clutch release bearing. And it is less tiring for you, too.

Clutch Adjustment

Inspect manual and self-adjusting clutches reg ularly to maintain correct clutch adjustment. Have your dealer’s service depar tment perform any adjustments necessary. Do not adjust your clutch by adjusting the external linkage without first checking (and correcting if necessary) the internal clutch adjustment. Using only the external linkage adjustment could damage the clutch.

PB1328 —70— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

Clutch Brake

Your clutch brake is used for stopping gear rotation to let you shift into 1st gear or reverse when your vehicle is at a standstill.

About the last 1/2 to 1 inch of clutch pedal travel activates your clutch brake. So if you are stopped and want to shift directly into 1st or reve rse, depress the clutch pedal until contact with the clutch brake is made to stop transmission gear rotation.

If you have a butt-tooth condition and can’t shift the transmission, gradually release the clutch. Then the drive gear can roll enough to allow the teeth to line up properly and complete the shift.

CAUTION: Be careful not to apply the cl utch 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. Applying the clutch brake when the vehicle is moving causes a braking effect on the entire vehicle. This wear naturally shortens the service life of your clutch brake.

Double Clutching

Whether you are upshifting or down shifting, it is best to double clutch. Double clutching is easier on your transmission and on your engine, helping your vehicle match engine speed with driveline speed and achieving clash-free shifts. To double clutch:

1. Push down the clutch pedal to disengage the clutch.

2. Move the gear shift lever to neutral.

3. Release the pedal to engage the clutch. This lets you control the RPM of the mainshaft gears. Thus you can match the RPM of the mainshaft gears to those of the output shaft.

Upshifts - Let the engine and gears slowdown to the RPM required for the next gear. Use the tachometer to determ ine optimum RPM for gear engagement.

Downshifts - Press accelerator to increase engine and gear speed to the RPM required in the lower gear. Use the tachometer to determine optimum RPM for gear engagement.

4. Now quickly press the pedal to disengage the clutch. Move the gear shift lever to the next gear speed position.

5. Release the pedal to engage the clutch.

PART 7: STARTING & OPERATING THE VEHICLE

Interaxle Differential

On vehicles with tandem rear axles, the interaxle differential allows each axle to turn independent ly. Differential action between the tandems relieves stress on the rear axles and tires and provides better performance.

When operating normally on paved, dry su rfaces, keep your truck’s interaxle differential in the UNLOCK position.

SHIFT AT ANY SPEED EXCEPT IF A WHEEL IS SPINNING

03029

Switch In Unlock Position

In the LOCK position, continuous operation on a paved, dry surface stresses the tandem axles, possibly causing internal damage to them.

Shift into the LOCK position to operate on slippery surfaces like

• Ice or snow - with or without tire chains.

• Dirt roads.

• Loose sand, mud, or other off-road conditions.

Switch into LOCK when checking performance on a chassis dynamometer.

WARNING! Do not put the differential lock in the LOCK position while the wheels are spinning freely (slipping), you could lose control of the vehicle or cause axle dam-

age—you could be injured. Switch to LOCK only when the wheels are not spinning.

WARNI NG! Do not operate the vehicle on dry pavement with the differential locked; it could lead to an injury accident. On dry pavement, you will not be able to steer well with the differential locked. Lock the differential only when operating on surfaces with poor traction, such as wet, slippery roads or loose gravel.

PB1328 —72— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

WARNING! 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 injury accident.

To reduce load o n the drive train, ease up on the t hrot tle pedal wh enever you shift into LOCK or UNLOCK.

Dual Range (Two Speed) Axles

If you have this option, dual range axles provide two rear axle ratios for operating under heavy loads or off-highway as well as for over the road trucking. The Low range provides m aximum torque for off -road work. The High range is a faster ratio for highway speeds and conditions.

A switch on your instrument panel controls this function. You will notice that it has a guard to protect you from activating it accidentally.

03030

Range Selector

Here’s how to use your dual range axle:

WARNI NG! Never shift the axle when moving down hill. 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 injury accident.

1. Unlock the interaxle differential before starting.

2. Put the Range Selector in the LOW range. Shift the transmission to start the truck moving.

3. Off-Highway: When you are driving on rough terrain and secondary roads, or under a very heavy load, keep the axle in the LOW range. Shift your transmission to maintain the road speed you want.

PB1328 —73— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

4. When you go from off-highway to highway driving, shift the axle to the HIGH range this way:

• Be sure the differential is UNLOCKED.

• Keep the accelerator down and move the Range Selector lever to

HIGH.

• Keep driving with the accelerator down until you want the axle to

shift.

• Then release the accelerator until the axle has shifted.

• You are now in the HIGH axle range on the highway. Shift the

transmission normally to reach your desired cruising speed.

5. If you need to downshift the axle for more power:

• Keep the accelerator down and move the Range Selector lever to

LOW.

• Keep driving with the accelerator down until you want to downshift

the axle.

• Then release and depress the accelerator pedal quickly to

increase the engine RPM.

• The axle will shift to the LOW range.

Important Ti ps on Operating Your Dua l R ange Axle

NOTE: If your vehicle has an automatic transmission, it ma y be necessary to shift it to the Neutral position momentarily to allow the main differential lock splines to fully engage or disengage.

• To avoid damaging your vehicle, shift the axle at a slower speed

until you are used to driving with the dual range axle.

When you are driving on a surface with good traction, keep the interaxle differential unlocked. You can drive with the axle in the LOW or HIGH range.

CAUTION: If you shift the axle range with the interaxle differential in LOCK, you could do serious damage to your axles. Never shift the axle range with the differential locked.

• Park the truck with the Range Selector in LOW.

Automated Transmissio n

An automated transmission makes shifting much easier, of course. But because your truck pulls a heavy load, if you have such a transmission, it is important to use it efficiently. For correct operation, see the manual for your automated transmission included with your vehicle.

WARNI NG! If your vehicle has a Freedomline™ 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. This could cause serious damage or personal injury. Observe the following guidelines:

•When stopped on a hill or grade, press the brake pedal.

•When starting from a stop on a hill or grade, quickly remove your foot from the brake pedal and firmly press on the accelerator pedal.

PART 7: STARTING & OPERATING THE VEHICLE

Auxiliary Transmission

If you have an auxiliary transmission, see your transmission manufac-

turer’s manual for its proper operation.

If Your Vehicle Must Be To wed

CAUTION: Remove the driveline and axle shafts or lift the driving wheels off the ground before towing the vehicle. You could seriously damage your vehicle by towing it with the driveline connected and the drive wheels on the ground. Worse, when vehicles are towed either by wrecker or piggy-back, the lubricant in the top front of the drive axle will drain to the rear. This will leave the top components dry. The resulting friction will seriously damage them. Always remove the main driveshaft and axle shafts before towing your vehicle.

Returning a Towed Vehicle to Service

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 inter-axle differential, add 2 pints (.94 liter) of lubricant. See the Index, under Lubricant Specifications, for the lubricant

required by each axle.

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).

This will thoroughly circulate the lubricant through the assembly.

Anti-Lock Braking System Operating Information

A Model 387 is equipped with an anti-lock braking system (ABS). This ABS reduces the possibility of whe el lock-up. If a wheel is about to lock during braking, the ABS will autom atically adjust air pressure to the brake chambers on the appropriate wheel(s) to prevent wheel lock-up. The ABS is automatically turned on when the ignition switch is turned on.

WARNI NG! 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.

PB1328 —76— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

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.

WARNING! Do not rel y on an anti-lock br ake system that is functioning improperly. You could lose control of the vehicle resulting in a severe accident and personal injury. If an ABS lamp goes on while you are driving or stays on after the self-check, that anti-lock system might not be working. The ABS may not function in an emergency. You will still have conventional brakes, but not anti-lock brakes. If any warning lamp indicates a problem, have that ABS checked.

ABS Warning Lamps

Truck/Tractor ABS Warning Lamp

A truck/tractor ABS warning lamp illuminates when the ignit ion switch is first turned on and will remain on until the system self-test has been completed successfully. Normally, this ABS lamp will remain on until a speed of no more than 9 mph has bee n reached and the speed sensors have been checked fo r correct output. The lamp should remain off after this point unless a problem in the system is detected.

CAUTION: If the truck/tractor ABS warning lamp does not illuminate when the ignition is first turned on, there is a problem with the bulb or wiring. The driver should have this checked as soon as possible.

The truck/tractor ABS lamp is located in the warning lamp cluster. (See illustration on page 42

Wheel Spin Control Warning Lamp

Your truck/tra ctor ABS ma y ha ve an accel erati on sli p regulation (ASR) or automatic traction control (ATC) feature. This feature is controlled by a switch as shown in the next illustration. Either of these features is monitored by a warning lamp located on the main dash.

ATC

03034

The Wheel Spin C ontrol war ning lamp will br iefly illuminate and then go out when the ignition switch is first turned on. The Wheel Spin Control warning lam p will illuminate whenever the ASR or AT C system detects drive wheel spin. The lamp will remain illuminated as long as wheel spin is detected and the ASR or AT C system is app lying the drive wheel brakes or reducing engine torque. Do not allow the Wheel Spin Control lamp to remain on continuously for an extended length of time. Extended continuous use of the ASR / ATC can cause overheating of the drive wheel brakes. Engine torque or vehicle speed should be reduced to eliminate wheel spin and prevent excessive application of the ASR / ATC system. Excep t for checking for proper illumination of the ABS and Wheel Spin Control warning lamps when first star ting the truck, and for monitoring these lamps while driving, no special operating procedures are required. For a detailed system description, see service literature for your specific ABS that was provided with your vehicle.

Brake Safety and Emergency

WARNING! Do not operate the vehicle in the event of a malfunction in any air circuit. The vehicle should not be operated until the system is repaired and both braking circuits, including all pneumatic and mechanical components, are working properly. Loss of system air can cause the service brakes not to function resulting in the sudden application of the spring brakes causing wheel lock-up, loss of control, or overtake by following vehicles. You could be in an accident and severely injured.

PB1328 —79— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

WARNING! Unless you have an anti-lock braking system, always avoid completely depressing the service brake pedal, if possible, even during emergency braking. Depressing the brake pedal too aggressively can cause the wheels to lock, which can lead to an uncontrolled skid and could cause an accident.

To stop your vehicle in an emergency, vary the s ervice brake application pressure to provide maximum braking force without locking the wheels. Use engine compression to assist the ser vice brakes; i.e.,

don’t depress the clutch pedal until the engine reaches idle speed.

Overh eated Brakes

Under normal braking condi tions, the energy generated will brin g the internal brake drum temperature to about 500° F (260° C). This is well within the safe zone: The maximum safe temperature of linings for drum type brakes is usually about 800° F (427° C).

But if service brakes are used i mproperly or for prolonged periods, internal brake drum temperatures may commonly exceed 800° F (427° C). Such brake overheating may be detected by a burning smell or smoke coming from a drum. If this occurs, you should immediately stop and check for cracked brake drums or lining fires. If neither exists, get back behind the wheel and resume a slow speed as soon as possible to cool the brakes.

Parking Brakes and Their Use

The yellow diamond-shaped knob on your instrument panel cont rols your parking brakes. These are spring brakes which you activate by releasing air pressure from their chambers. When they are not in use, air pressure compresses the springs and releases the brakes. But putting the valve in the “Park” position exhausts air from the chambers and allows the spring s to extend and apply the brakes. Also, if your system air drops below the safe operating level, the spring brakes will apply automatically, bringing your vehicle to a stop.

WARNI NG! On trailers buil t bef ore March 1975 you may not have parking brakes if the trailer reservoir pressure leaks down. If you depend on them to hold your vehicle, they could release, causing a serious accident. These older trailers have emergency brakes not designed for parking. They will apply only if there is enough trailer

reservoir pressure. Don’t use your trailer emergency brakes for parking. Apply your tractor parking valve too.

Red / Yellow Controls

WARNING! Do not leave the cab without applying the parking brake. The truck could roll and cause an injury accident. Always apply the parking brake before you leave the cab.

WARNING! Stopping with the parking brake controls can cause a sudden wheel lock-up, loss of control, or can cause you to be overtaken by following vehicles. You cou ld be severely injured. Never pull out the parking brake valve while the vehicle is moving.

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.

WARNING! Never drive your vehicle with the parking brake applied. Always release the parking brakes prior to moving the vehicle. Failure to disengage the parking brakes prior to moving your vehicle could result in excessive heat buildup in the brake system, resulting in a fire.

NOTE: Today’s diesel electronic 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.

To apply all your parking brakes, pull the yellow knob Out. The parking brakes will set. And the trailer air supply valve (red octagon knob) will automatically pop out, releasing air pressure and setting the trailer brakes.

PART 7: STARTING & OPERATING THE VEHICLE

CAUTION: Do not try to put th e vehicle in motion bef o r e 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).

Manually Re le asing Spr ing B r akes

You may sometime have to release your vehicle’s spring brakes by hand to allow the vehicle to be towed. This could happen if the system air pressure doesn’t reach operating pressure because your engine or compressor is not working properly. You will have to release the spring brakes at the spring brake chambers.

WARNING! Do not operate a vehicle when the spring brakes have been released manually. Driving a vehicle that has had its spring brakes manually released is extremely dangerous. You would probably have no brakes at all. You could have a serious or fatal accident.

WARNING! Releasing the spring brakes on an unsecured vehicle could lead to an accident. The truck could roll, causing severe injury . Always secure the truck with wheel chocks, chains, or other safe means to prevent rolling before manually releasing the spring brakes.

WARNING! Disassembling the spring brake chamber is dangerous and could cause serious injury. These chambers contain a powerful spring that is compressed. Sudden release of t his spring could cause you to be badly injured. Do not disassemble a spring brake chamber.

NOTE: The primary purpose of the manual release feature is to permit the vehicle to be towed to a repair facility.

PB1328 —83— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

To release spring brakes manually:

1. Remove the cap from the spring chamber.

2. Remove the release stud assembly from the side pocket; remove the release nut and washer from the release stud.

Retarders

Various retarders are available which function against the engine,

driveline, or transmission. These are devices that use your engi ne’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 ser vice brakes only for stopping completely. Operating this way will greatly prolong the life of your brakes.

WARNI NG! In an emer gency, the retarder might not stop you fast enough to prevent an accident. You could be badly hurt if you relied only on your retarder. Use the service brakes for quick stops. The retarder is not an emergency brake.

WARNING! The retar der 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.

WARNING! The service brakes must be used in an emergency. The retarder alone might not stop you fast enough to prevent an accident. You could be badly hurt if you relied only on the retarder.

WARNING! Do not use the 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 if the wheels begin to skid, resulting in an accident.

Driving Bobtail or with an Unloaded Trailer

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 bra k in g. You could be

injured. Don’t use your retarder when you are driving bobtail or with an unloaded trailer.

Pyrometer

Maintaining Correct Operating Temperature

The optional pyrometer indicates engine exhaust gas temperature. Because it responds almost immediately to changes in exhaust temperature, the pyrometer is an excellent indicator of engine output.

If you watch engine speed and exhaust temperature ranges, the pyrometer can help you operate your truck more efficiently and avoid sudden changes in engine operating temperature.

CAUTION: Do not allow the pyrometer reading to exceed the specified maximum operating temperature. If the pyrometer has no label specifying the maximum operating temperature for the pyrometer, contact your engine distributor for a recommendation.

NOTE: Different size injectors or changes in altitude may affect engine operating and exhaust temperatures.

Procedure For Reducing High Pyrometer Temperature Readings

1. If the pyrometer indicates excessive temperature, ease up slightly on the throttle.

2. If RPM and speed drop, downshift one gear to help lower the exhaust temperature.

3. Observe the pyrometer reading. If the temperature continues to be high, continue downshifting until acceptable operating temperatures can be maintained.

Stopping The Engine

Before Stopping The Engine

A hot engine stores a great amount of heat, and it doesn’t co ol down immediately after you shut it off. Always cool your engine down before shutti ng it of f. You will g r ea tl y incre ase its ser v ic e li fe.

Idle the engine at 1000 RPM for five minutes. Then low idle for th irty seconds before shutdown. This will allow circulating coolant and lubricating oil to carr y away heat from the cylinder head, valves, pistons, cylinder liners, turbocharger, and bearings. This way you can prevent serious engine damage that may result from uneven cooling.

Turbochargers

This cooling-down practice is especially impor tant on a turbocharged engine. The turbocharger contains bearings and seals that are subjected to hot exhaust gases. While the engine is operating, heat is

PB1328 —87— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

carried away by circulating oil. If you stop the engine suddenly after a hard run, the temperature of the turbocharger could rise as much as

100°F (55°C) above the temperature reached during operation. A sudden rise in temperature like this could cause the bearings to seize or the oil seals to loosen.

Refuel Before the Final Stop

Air space in your fuel tanks a llows water to condense there. To prevent this condensation while you are stopped, fill your tanks to 95% of capacity.

Final Stop

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.

Final Stopping Procedures

1. Set the parking brake before leaving the driver’s seat. To hold your vehicle while it is parked, don’t rely on

•Air Bra kes

•Hand Control Valve for Trailer Brakes

•Engine Compression

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 a serious accident. Someone could be hurt or killed. Always set the parking brakes. Never rely on the trailer hand brake or truck air brakes to hold a parked vehicle.

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. If your vehicle is equipped with a Peterbilt rear air suspension, and if it bec om es necessary to reset the r ide height, you may temporarily set it by following the next procedure. Proper ride height measurement and values are shown in the illustration and table below.

PART 7: STARTING & OPERATING THE VEHICLE

CAUTION:

•

The rear of a vehicle will drop about 3 1/2 inches (88 mm) when the air s prings are deflated. Ensu re that no persons or objects that coul d be injured or dama g e d are under the vehicle before deflating the air springs.

•

To minimiz e risk of damag e or in ju ry, 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.

•

To minimize risk of injury, keep away from air springs as they are being inflated.

NOTE: On dual-valve systems, begin with the LH valve on the next step.

2. Loosen the fasteners mounting a hei ght control valve to its bracket.

NOTE: At least one of the mounting holes in the height control valve bracket will be slotted to permit rotating the valve.

3. Rotate the valve ei ther clockwise or countercl ockwise until air pressure in the air springs provides the ride height specifi ed f or that suspension. Measure the ride height from the bottom of the frame rail to the approxim ate cen terli ne of the rearmost drive ax le hub:

• For tandem axles, make the vertical measurement at the center-

line of the suspension (see illustration on page 91).

• For a single axle, make t he measurement in front of the axle, in the

area forward of the tires but not past the suspension bracket.

4. When at the correct ride height, ensure that the height control valve lev er is in the neutral position, then install either the built-in alignment pin or a 1/8-inch (3 mm) dowel (see page 91).

5. Torque the mounting fasteners to 55 — 75 Lb. in. (6.2 — 8.5 N.m.).

6. Remove the alignment pin or dowel.

7. Repeat Steps 2 through 6 above for the RH valve on vehicles with a dual-valve system.

PART 7: STARTING & OPERATING THE VEHICLE

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! Your brakes could fail if you continue driving with deflated air springs. Air escaping from the system will lower the air pressure, which could cause a spring brake to engage. The spring brake may cause

your brakes to drag and burn up the linings. Don’t continue to operate in this condition.

You can get to a repair facility if you do the following:

• Remove the height control link connected to the axle and to the

suspension air valve control arm. This will cause the air valve control arm to center in the closed position.

• The air system can then be pumped up to normal pressure for

continued operation.

WARNING! Low air pressure could make the brakes unsafe f or driv ing. Before drivin g th e vehi c le, make sure the pressure does pump up to over 100 psi for normal brake operation. If the air pressure does not pump up to at least 100 psi, don’t try to move the vehicle.

Driving Tips And Techniques

This section covers additional driving tips and techniques on h ow to drive your Peterbilt more efficiently. For further information, read the American Trucking Association’s (ATA) will give you more tips on starting, shifting, and driving your vehicle.

Coasting

Truck Driver’s Handbook

WARNING! Do not coast with the transmission in neu-

tral or with the clutch pedal depressed—it is a dangerous practice. Without the use of the retarding power of the drivetrain, your vehicle can reach dangerous speeds. At very high speeds you may not be able to put the transmission in any gear. At high speeds you could seriously damage your vehicle or cause an accident when you put the transmission in gear. The engine speed could exceed the maximum governed speed and cause a serious accident due to mechanical failures.

Do not coast with the transmission in neutral or with the clutch pedal depressed. Besides being illegal and dangerous, coasting is also expensive. It causes premature failure or damage to the c lutch and transmission and overloads the brake system.

Coasting with the transmission in n eutral also prevents proper transm ission component lubrication. During coasting the transmission is driven by the rear wheels, and the countershaft g ear (which lubricates the tr ansmission components by oil splash) will only be turning at idle speed.

Descending a Grade

. It

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 personal injury and/or an accident, before going down a steep or long grade, reduce speed and shift the transmission into a lower gear to help control your vehic le speed. F ailure to f ollow procedures f or proper downhill operation could result in loss of vehicle control.

PB1328 —94— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

Engine Overspeed

CAUTION: To avoid engine damage, do not let the engine

rpm go beyond the maximum governed rpm—valve damage could result if overspeed conditions occur.

NOTE: Often these recommendations are secondary to maintaining an adequate and safe speed relative to the surrounding traffic and road conditions.

• Operate the engine within the optimum engine rpm range and do

not allow the rpm’s to exceed the maximum governed speed. See

Engine Operation and Maintenance manual

your regarding engine rpm. When the engine is used as a brake to control vehicle speed (e.g., while driving down a grade), do not allow the engine rpm to exceed maximum governed speed.

• Under normal load and road conditions operate the engine in the

lower end of the range.

Use of Tachometer

The tachometer is an instrument that aids in obtaining the best performance of the engine and manual transmission, se rving as a guide for shifting gears. Refer to the

for optimum engine rpm.

ual

If the engine rpm moves beyond the maximum governed speed, indicating an overspeed condition, ap ply the service brake or shi ft to a higher gear to bring engine rpm within the optimum speed range.

Engine Operation and M aintenance m an-

• 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. However, the governor has no control over the engine r pm when it is being driven by the vehicle’s transmission, for example, on steep downgrades. Apply service brakes or shift to a higher gear.

Fuel economy and engine performance is also directly related to driving habits:

• The best results in trip time and fuel economy are obtained while

driving the vehicle at a steady speed.

• Shift into higher or lower gears (or apply the service brake) to keep

engine rpm near the lower end of the optimum operating range.

• Avoid rapid acceleration and braking.

PART 7: STARTING & OPERATING THE VEHICLE

Warning Alarms

A warning alarm occurs when some condition in the vehicle requires attention. A warning alarm cannot be turned off or manually reset. Once triggered, an alarm wi ll continue to exist until the unacceptable condition or fault in a function is corrected. Warning alarms can be generated by two main sources in a Model 387: the multiplex instrumentation system and (if equipped) the digital message center.

Multiplex Instrumentat ion System Alarms

NOTE: In addition to the warning messages mentioned in this part - if any of the following conditions occur after startup and self-test, the multiplex instrumentation system should be serviced:

•The speedometer-message center (SMC) pointer exhibits windshield wiper-like motion and the display reads NO DATA.

•One or more gauge pointers exhibit wiper-like motion.

•A gauge pointer stays at zero with its red light flashing.

•A gauge pointer goes to and remains at a 2:00 position with its red light on steady .

A multiplex instrumentation system alar m can be signalled by up to four indicators:

• A warning message will appear on the SMC display (all alarms).

• The light-emitting diode (LED) warning light in the function’s gauge

will go on (all alarms except ABS and multiplex instrumentation system faults).

• An audible alarm will sound.

• A light bar icon will light.

NOTE:

•

Warning messages from system alar ms with an audible alarm can be temporarily overridden by pressing the Reset switch. You can then press the Select switch to scroll through other functions - but the message will reappear in 60 seconds. The audible alarm will always be on.

•Warning messages from system alarms without an audible alarm can be dismissed by pressing the Reset switch. To view dismissed active messages, turn the ignition off and back on.

An alarm’s warning message on the SMC will pr eem pt all other SMC displays until the condition that is causing the alarm is corrected. This preemption includes other warning messages from earlier alarms and some of these alarms may not have other indicators. Therefore, it

PB1328 —96— 22-02011 (R02/02)

PART 7: STARTING & OPERATING THE VEHICLE

is very impor tant that you check the SMC to be aware of all alarm

conditions that may exist in your vehicle’s systems - especially during the start-up proc edure. A summar y of alar ms and indicators is at th e end of this part. Follow this procedure to check all SMC warning messages.

1. Observe the first message displayed after the SMC comes on.

• If the odometer is displayed, continue with the start-up procedure.

• If a warning message is displayed instead of the odometer, it is

being generated by the multiplex instrumentation system:

-Look in the summary on page 98 to identify the alarm (gauge).

-Go to the description of that gauge in PART 4: CONTRO LS A ND

DISPLAYS and take the actions indicated to correct the condi-

tion.

2. Continue to check and act on all warning messages until the odometer is displayed.

Digital Message Center Alarms (Faults)

If so equipped, the digital message center (DMC) in a vehicle will detect preselected faults during operations. When a new fault is

detected, a LED next to the DIAG key on the DMC’s keypad will illuminate. All faults are either active or inactive (active faults are conditions that still exist within the vehicle).

• Active faults cannot be erased until they become inactive. They

should be investigated as soon as possible.

• Inactive faults can be erased by using the CANCEL key on the

DMC.

Refer to the DMC operator’s manual that came with your vehicle for more information.
