PART 1: INTRODUCTION HOW TO FIND WHAT YOU WANT

PART 1: INTRODUCTION

This manual contains useful information for the safe and

efficient operation of your P eterbilt 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 functions, controls, and operation - and to present it as clearly as possible. We hope you’ll find this manual easy to use.

Please remember -- 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 th e 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 you need quickly and easily.

First is the Quick Table of Contents. Located at the front of the manual, this lists the main subjects covered and gives page numbers where you can find these subjects. Use the Quick Table of Contents to find information on a large subject like “Maintenance.”

Cross-referenced citations also help you get the information you need. If some other part of the manual contains further information o n the subject you are reading about, we’ll indicate that in a cross-reference like this: (See “PART 6: DRIVER’S CHECKLIST”). You won’t have to go searching for more information.

Finally you’ll find a helpful Subject Index. It’s in the back of the manual and alphabetically lists the subjects covered. So if you want information on brakes, for example, just look under Brake in the Subject Index. You’ll find all the pages listed where brakes or braking are discussed.

PART 2: CAB AND FRAME ACCESS DOOR LOCK AND KEYS

Remote Keyless Entry (optional)

This vehicle may be equipped with a Remote Keyless Entry (RKE) system that adds security and convenience to your vehicle. The system will lock or unlock the driver’s door and passenger’s door with the key fob and alert you with parking lights when the selected door’s are locked or unlocked. The system includes two key fobs that provide secure rolling code technology that prevents someone from recording the entry signal.

Operation

To Unlock The Driver’s Door

Press the UNLOCK button once. The driver's door will unlock and the parking lights will come on for 40 seconds.

To Unlock The Passenger’s Door

Press the UNLOCK button once and press again within 5 seconds. The passenger door will unlock.

To Lock Both Doors

Press the LOCK button. The doors will lock and the parking lights will come on for 2 seconds. If the doors are open they will not lock. The range of the RKE sys-

tem should be approximately 30 ft. This will be reduced if it is operated close to other RF sources such as TV/radio transmitters and cell tow ers.

Batteries

The key fob uses one CR2032, 3V battery. Batteries should last approximately three years, depending on use. Consistently reduced range is an indicator that the battery needs replacement. Batteries are available at most discount, hardware and drug stores.

To Replace The Battery

1. Remove rear cover from key fob.

2. Remove the battery.

3. Install new battery.

4. Reinstall cover.

5. Synchronize the key fob.

PART 2: CAB AND FRAME ACCESS CLIMBING ONTO THE DECK PLATE

Climbing Onto the Deck Plate

When you are climbing onto and off the deck plate, maintain at least three points of contact with your hands on the grab handles and your feet on the steps.

WARNING!

• You can be hurt if you aren’t careful climbing onto and off the deck plate. You can slip and fall, especially if the surfaces are wet or icy, or if you step in oil, fuel, or grease. Keep steps clean. Always maintain at least three points of contact between your hands and feet and the steps and deck plate.

• Do not climb onto and off the dec kplate–use steps and grabhandle provided. If there is no deck plate, or if proper steps and grab handles aren’t provided, don’t c limb onto the area behind the cab. Peterbilt did not intend for the area to be a step if handrails or proper steps are not provided.

WARNING! Do not step on vehicle components without antiskid surfaces or use components not designed for entry-and-exit use. You could fall and injure yourself if you step on a slippery surface. For example:

• You could fall and injure yourself if you step onto a fuel tank surface. A fuel tank is not a step. The tank surface can get very slippery, and you might not be able to prevent a fall. Don’t step onto the surface of a fuel tank. Use only the steps and handholds provided, not chain hooks, quarter fenders, etc.

• Always reinstall steps before entering the cab or accessing the deck plate. Without steps, you could sli p and fall, resulting in possible injury to yourself.

NOTE: Any alteration (adding bulkheads, headache racks, tool boxes, etc.) behind the cab or sleeper that affects the utilization of grab handles , deck plates, or frame access steps installed by Peterbilt must comply with FMCSR 399.

The pictures on the next page show you the right way to get on and off the area behind your cab.

Engine Oil Pressure Gauge

It is important to maintain oil pressure within acceptable limits. Your engine manual will give normal operating pressures for your engine.

CAUTION: Continuing to operate your vehicle with insufficient oil pressure will cause serious engine damage.

• If your oil pressure fails to rise within 10 seconds after your engine starts, stop the engine and determine the cause.

• If your oil pressure suddenly drops while you are driving, bring the vehicle to a stop as soon as possible in a safe location off the road and turn off the engine. Wait a f ew min utes to allow oil to dr ain into the oil pan, and then check the oil le v el. Add oil if necessary. If the problem persists, contact an authorized service center.

Check the engine manufacturer’s manual for the correct oil pressure ranges for your engine.

Water Temperature Gauge

The water temperature gauge shows the temperature of the engine coolant. Under normal operating conditions the

(08/06) Y53-6004 – 37 –

STANDARD GAUGES PART 4: CONTROLS AND DISPLAYS

water temperature gauge should register between 16 5° and 205°F (74° and 90°C). Under cer tain conditions, somewhat higher temperatures may be acceptable. But the maximum allowable temperature is 210°F (99°C) with the cooling system pressurized, except for cer tain special engines. Check your engine manual to be sure.

Engine Overheating

WARNING! Do not remove the radiator fill cap while the engine is hot. Scalding steam and fluid under pressure may escape and cause serious personal injuries. You could be badly burned.

• Wait until the coolant temperature is below 122°F (50°C).

• Protect face, hands, and arms by covering the cap with a large, thick rag to protect against escaping fluid and steam.

• Carefully and slowly turn the cap one-quarter of a turn or until it reaches the first stop— allowing excess pressure to escape—push down and turn for final removal.

Wait until the coolant temperature is below 122° F (50°C). Protect your face, hands, and arms by covering the cap with a large, thick rag to protect y ou aga inst escaping fluid and steam. Before you completely remove the cap, carefully and slowly turn the cap part way to allow excess pressure to escape. Then push down and turn for final removal.

The cooling system may overheat if the coolant level is below normal or if there is a sudden lo ss of co olant (s uch as a worn hose splitting). It may also temporarily overheat during severe operating conditions such as climbing a long hill on a hot day or stopping after high-speed driving.

If the “Engine Coolant Temperature” warning light comes on, or you have any other reason to suspect the engine may be overheating:

• Stop the vehicle, but DO NOT TURN OFF THE ENGINE unless a low water warning device indicates a loss of coolant.

• With the transmission in neutral, check to be cer tain the oil pressure gauge reads nor mal. Increase the engine speed to about 1100 - 1200 RPM, maximum. Return the idle speed to normal after 2 or 3 minutes. If

tion of moisture in the tanks. This moisture can damage your engine.

Primary (Secondary) Air Pressure Gauge (Air Reservoir)

The air pressure gauge indicates the amount of air pressure in the brake system in pounds per square inch (psi).

• The primary gauge shows front reservoir air pressure.

• The secondary gauge shows pressure in the rear reservoir.

Ensure the air pressure registers more than 100 psi in both service systems before you move the vehicle. If the pressure in either circuit is too low for normal brake operation, the warning light will glow and the audible alarm will sound.

– 40 – Y53-6004 (08/06)

PART 4: CONTROLS AND DISPLAYS OPTIONAL GAUGES

WARNING! The air pressure warning light and the audible alarm indicate a dangerous situation. There is not enough air pressure in the reservoirs for repeated braking and the brake system has failed. If air pressure falls below 60 psi (414 kPa) the spring brakes could suddenly apply, causing a wheel lockup, loss of control, or your vehicle to be overtaken by following vehicles. You could be in an accident and severely injured. If these alarms come on while you are driving, bring your vehicle to a safe stop right away. If the light and alarm do not turn off at start-up, do not try to drive the vehicle until the problem is found and fixed.

SEAT BELTS AND THEIR PROPER USE PART 5: SEAT AND RESTRAINT SYSTEMS

WARNING!

• Always wear your seat belt low over your pelvic bones.

• 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 can result in serious internal injuries.

• Do not drive with your seat belt loose. A seat belt that is too loose 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 1 in. (25mm) of slack.

• Do not wear the shoulder belt under your arm or otherwise out of pos ition. In a crash your body wo uld mo ve too far f orward, increasing the chance of head and neck injury. Also, the belt would apply too much f or ce 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.

• Do not twist the belt in the process of putting it on. A twisted belt will not work as well to protect you. In a crash, the full width of the belt would not be protecting you. A twisted belt could cut into your body and cause serious injuries. Straighten the belt before buckling it. If you are unable to wear it without twisting it, have your dealer or service person repair it as soon as possible.

Komfort-Lok® Feature

Your Peterbilt contains a feature designed to eliminate cinching and 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 feature increases with rough road conditions, particularly over long distances.

To eliminate cinching simply activate the Komfort-Lok feature at the appropriate time:

1. Fasten your seat belt according to the directions.

Sleeper Bunk Restraints

If your cab is equipped with a sleeper, be sure to use the restraint device. You may have belts which either are over the bunk or cov er the opening. Of course, y ou do not need to use a restraint if you sleep in a parke d vehicle. But anyone using the sleeper while the truck is in motion should be restrained in a safety device.

You will notice that if your Peterbilt has an upper bunk, it has no restraint device. This is because no one should ever be in an upper bunk when the vehicle is moving.

WARNING!

• In an accident an unrestrained person lying in a sleeper bunk could be serious ly inju r e d . He or she could be thrown fr om the bunk. Be sure anyone occupying the sleeper is restrained while a vehicle is mo v i n g .

• 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 to it that e v eryone in the v ehicle rides safely - and that means with a seat belt.

Some Other Safety Restraint Tips:

• Don’t wear belts over rigid or breakab le objects in or on your clothing. Such things might be eyeglasses, pens, keys, etc. These could cause injury in an accident.

PART 5: SEAT AND RESTRAINT SYSTEMS SEAT BELTS AND THEIR PROPER USE

• 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.

• Never 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.

Do not remove, modify, or replace

Tether Adjustment

WARNING!

• 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.

• 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 b uc kle on each side.

• To lengthen the tether, turn the buckle to a right angle to the webbing. Then pull the buckle. To shor ten the tether, pull on the strap.

INSPECTION OF THE RESTRAINT SYSTEM PART 5: SEAT AND RESTRAINT SYSTEMS

Inspection of the Restraint System

WARNING! Failure to properly inspect and maintain restraint systems can lead to seriou s injury or loss of life. Without periodic inspection and maintenance to detect unsafe conditions, seat restraint components can we ar 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, b ut ther e are some k e y differences that all users of this system should be aware of:

• In typical passenger vehicle automotive seat belt applications, the normal life of the v ehicles 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 short 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 movement 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 mo v ement of the w ebbing in the seat belt system when the belt in 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 he a vy duty and specialty vehicles. Unlike the automotive environment, heavy duty and specialty vehicles may be ver y 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 associated with heavy duty v ehicles 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 three-

PART 5: SEAT AND RESTRAINT SYSTEMS INSPECTION OF THE RESTRAINT SYSTEM

point 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 sev ere en vironmental conditions. An y seat belt system that shows cuts, fraying, extreme or 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 th e seat belt webbing. Constant movement of the belt actually 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 i ndicate that belt rep lacement is necessary.

1. Check the web wear in the system. The we bbing m ust be closely examined to determine if it is co ming into contact with any sharp or rough surfaces on the seat or other parts of the cab interior. T hese ar ea s ar e typical places where the web will experience cutting or abrasion. Cuts, fraying, or excessive wear would indicate the need for replacement of the seat belt system.

(08/06) Y53-6004 – 81 –

INSPECTION OF THE RESTRAINT SYSTEM PART 5: SEAT AND RESTRAINT SYSTEMS

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 Komfort Latch™ 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 f or 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.

WARNING! 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 t he seat is

03004A

in its most upward and forward position.

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

– 82 – Y53-6004 (08/06)

PART 5: SEAT AND RESTRAINT SYSTEMS INSPECTION OF THE RESTRAINT SYSTEM

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.

WARNING!

(retractor and buckle side) if replacement of any one part is necessary. Une xposed damage to one or more components could prevent the system from functioning properly the next time it is needed, which could result in severe injury or even death.

Replace the entire belt system

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 replacement belt. This set of instructions is entitled “THREE-POINT SEAT BELT INSTALLATION GUIDE.” There are separate seat belt 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 recommended replacement seat belt. The occupant restraint system has been dev eloped and tested specifically f or this vehicle. If the vehicle was originally equipped with a lap belt, it cannot be replaced with a three-poin t sh oulder harness system, because the cab mounting points are not structurally designed for a three-point seat belt.

NORMAL TEMPERATURE STARTING PROCEDURE PART 7: STARTING & OPERATING THE VEHICLE

PART 7: STARTING & OPERATING THE VEHICLE

Since each vehicle is custom-equipped, all engine operation instructions in this manual are general. You will want to consult the manual for your engine to find out details about your specific engine’s needs. You may need to use a slightly different procedure from the one outlined here.

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 normal-temperature starting and cold-weather starting.

Normal Temperature Starting Procedure

When the outside temperature is abov e 50° F (10° C) , yo u 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. Turn the key switch to ON.

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

NOTE:

protection. Check the “Engine Operation and Maintenance Manual” for details.

5. Turn the ignition key to the START position. If the engine does not start within 30 seconds, release the starter button. To av oid ov ertaxing the starter motor or the batteries, don’t use the starter for more than 30 seconds. Let the starter motor cool and the batteries recover for two minutes before trying again.

If the engine still won’t start after a couple of tries, check the manual override shutdown valve and fuel lines for possible fuel starvation or air leaks. Star ting 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

Some starters are equipped with overcrank

pressure doesn’t rise within a few seconds, stop the engine. Find out what is wrong before restar ting the engine.

7. Slowly engage (release) the clutch after the engine has started.

8. Wait until normal engi ne oil pressure register s on the gauge before idling or acceler ating the en gine be y ond 1000 RPM.

Cold Temperature 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 sta rting. If you follo w a f ew simple guidelines , y ou will e xtend 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.

Ether Metering Equipment

WARNING! The fluid in ether starting systems is extremely flammable and poisonous. If ignited, it could burn you badl y. If you swallow it, it can be harmful or fatal.

• Do not smoke when testing, installing, or servicing an ether starting unit. Service it in a well-ventilated area away from heat, open flames, or sparks.

• If swallowed, do not induce vomiting. Call a physician immediately.

• Wear goggles to avoid getting fluid in your eyes. Avoid getting it on your skin and avoid breathing the fumes. If fluid does get in your eyes or fumes irritate your eyes, flush for 15 minutes with large amounts of clean water. Contact an eye specialist.

• Do not move or relocate the ether cylinder or tubing from its original installation. It must be mounted to protect it from engine exhaust heat and from moving parts which could damage it.

• Do not store the spare cylinder in the cab.

(08/06) Y53-6004 – 89 –

ENGINE WARMUP PART 7: STARTING & OPERATING THE VEHICLE

• In warm weather, when y ou will not need the ether starting system, remove the ether bottle from your truck and store it safely. Return the protective cap to the bottle mounting connector.

In cold weather the engine will start faster and the star ter motor will work more easily if ether is injected into the engine cylinder while the engine is being cranked.

Automatic System

When you turn the ignition switch to the START position, the cranking motor and the ether system are engaged. When needed, starting fluid is released from a pressurized cylinder , flows through a v alve and tubing, and spr a ys from a nozzle in you engine’s air intake system.

For more helpful starting information, refer to the engine manual that came with your vehicle.

Engine Warmup

The purpose 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

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 warms, reducing oil available for the bearings. Watch the engine oil temperature or pressure gauge for a warmin g trend before increasing engine idle speed (RPM).

– 90 – Y53-6004 (08/06)

PART 7: STARTING & OPERATING THE VEHICLE ENGINE WARMUP

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) be fore operating at full throttle.

WARNING!

tain carbon monoxide, a colorless and odorless gas. Do not breathe the engine exhaust gas. A poorly maintained, damaged or corroded exhaust system can allow carbon monoxide to enter the cab or sleeper. Entry of carbon mono xide into the cab is also possible from other vehicles nearby. Failure to properly maintain your vehicle could cause carbon monoxide to enter the cab/sleeper and causes serious illness.

Exhaust fumes from the engine con-

CAUTION: Never idle your vehicle for prolonged periods of time if you sense that exhaust fumes are entering the cab or sleeper. Investigate the cause of the fumes and cor rect it as soon as possible. If the vehicle must be driven under these conditions, drive only with the windows slightly open. Failure to repair the source of the exhaust fumes may lead to personal harm.

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 damage. If you must use a winterfront

• Refer to the “Engine Operation and Maintenance Manual” for operating restrictions and recommendations.

• Use only a winterfront available from your Peterbilt dealer that is compatible with a 2002 EPA-compliant engine cooling system. These winterfronts are specifically designed for use with new grill snap patterns.

NOTES:

• 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

ENGINE WARMUP PART 7: STARTING & OPERATING THE VEHICLE

NOTES:

• If other vehicles are parked next to you idling, move your vehicle or do not stay in your vehicle for prolonged periods of time.

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.

WARNING!

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 serious engine damage or a fire.

To reduce the chance of personal

CAUTION: Do not allow your engine to idle, at low rpm's (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.

During the time it takes you to drink a cup of coffee, your engine can cool as much as 60° F (33° C) below normal operating temperature. To keep the engine warm during a short break, turn it off. And don’t allow your engine to idle longer than five minutes.

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. Refer 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 may 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

Do not carry loose objects in your

lubricant to circulate and coat the contacting surfaces of the gears. Metal contacting metal in moving parts may seriously damage your transmission. So don’t driv e in one gear for long until the transmission lubricant has had a chance to coat those contacting surfaces.

Operating the Clutch

“Riding” the Clutch

The clutch pedal is not a footrest. Driving with y our f oot 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 down on the clutc h 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

(08/06) Y53-6004 – 93 –

PUTTING THE VEHICLE IN MOTION PART 7: STARTING & OPERATING THE VEHICLE

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 f ew hundred miles. As your clutch lining wears and high spots get worn smooth, you will get less free travel.

Always start out in a low gear with a ceramic-faced clutch. Starting in higher gears, even with a light load, will cause a very jumpy start and excessive wear.

And don’t allow your vehicle to roll in the opposite direction at all during clutch engagement. If you need to start up on an incline, apply your service brakes before you release the parking brake. Then release your ser vice 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 foot off the pedal). This helps preven t u nne ces-

sary wear of your clutch release bearing. And it is less tiring for you, too.

Clutch Adjustment

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

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 reverse, depress the clutch pedal until contact with the clutch brake is ma de to stop transmission gear rotation.

If you have a butt-tooth con di tion and ca n’t shift the transmission, gradually release the clutch. Then the drive gear

– 94 – Y53-6004 (08/06)

PART 7: STARTING & OPERATING THE VEHICLE PUTTING THE VEHICLE IN MOTION

can roll enough to allow the teeth to line up properly and complete the shift.

CAUTION: Be careful not to apply the clutch brake while the vehicle is moving. The purpose of the clutch brake is to stop the transmission so that you can shift into a starting gear without grinding. 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 clashfree 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 y ou 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 ne xt gear. Use the tachometer to determine optimum RPM for gear engagement.

Downshifts - Press accelerator to increase engine and gear speed to the RPM required in the lo wer g ear . 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.

Interaxle Differential

On vehicles with tandem rear axles, the inter axle differential allows each axle to turn independently. Differential action between the tandems relieves stress on the rear axles and tires and provides better performance. When operating normally on paved, dry surfaces, keep your truck’s interaxle differential in the UNLOCK position.

• Do not use the differential lock during downhill operation or at sp eeds abo ve 25 mph (40 km/h). When it is engaged under these conditions, your vehicle will exhibit “understeer” handling characteristics. This “un dersteer” 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 on the drive train, ease up on the throttle pedal whenever 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 tr ucking. The Low range provides maximum 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.

RANGE SELECTOR

Range Selector

How to use your dual range axle:

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 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 te rrain 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.

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

A. Be sure the differential is UNLOCKED.

B. Keep the accelerator down and move the Range

Selector lever to HIGH.

C. Keep driving with the accelerator down until you

want the axle to shift.

D. Then release the accelerator until the axle has

shifted.

(08/06) Y53-6004 – 97 –

PUTTING THE VEHICLE IN MOTION PART 7: STARTING & OPERATING THE VEHICLE

E. You are now in the HIGH axle range on the high-

way. Shift the transmission normally to reach your desired cruising speed.

5. If you need to downshift the axle for more power A. Keep the accelerator down & move the Range

Selector lever to LOW.

B. Keep driving with the accelerator down until you

want to downshift the axle.

C. Then release and depress the accelerator pedal

quickly to increase the engine RPM.

D. The axle will shift to the LOW range.

Important Tips on Operating Your Dual Range Axle
