1996 Ford F 150 Owners Manual

R (Reverse) With the gearshift in the R (Reverse) position, the vehicle will move backward. You should always come to a complete stop before shifting into or out of R (Reverse). Driving When to use D (Drive) This is the normal driving position. As the vehicle picks up speed, automatic upshifts from First gear to Second and Second to Third will occur. The transmission automatically downshifts as speed decreases. When to use 2 (Second) Use 2 (Second) to drive up moderately steep grades, to start-up on slippery roads or to provide engine braking on downgrades. Do not go faster than 55 mph (88 km/h) in this gear.

When to use 1 (Low) Use 1 (Low) to drive up steep grades and to provide maximum engine braking on hilly roads. Upshifts from 1 (Low) can be made by manually shifting to 2 (Second) or D (Drive). Selection of 1
(Low) gear provides only First gear operation at start-up. When driving, manually shifting to 1
(Low) will result in downshifts to Second gear or First gear depending on vehicle speed. NOTE: Do not drive faster than 30 mph

(48 km/h) in this gear.

P (Park) Always come to a complete stop before you shift into P (Park). This position locks the transmission and prevents the rear wheels from turning. To securely latch the gearshift in the P (Park) position, pull it toward you, push it completely counterclockwise against the stop, and then push it toward the instrument panel. The gearshift is securely latched in P (Park) if you cannot rotate it in a clockwise direction without lifting it toward you.

RWARNING

Always set the parking brake fully and make sure that the gearshift is securely latched in P (Park).

RWARNING

Never leave your vehicle unattended while it is running.

When the transfer case is in the N (Neutral) position, the engine and transmission are disconnected from the rest of the driveline. Therefore, the vehicle is free to roll even if the automatic transmission is in P (Park) or the manual transmission is in gear.

Forced Downshifts

To gain added acceleration in D (Drive) (when passing another vehicle) push the accelerator to the floor. The transmission will downshift to Second gear at speeds from about 35 to 55 mph (56 to 88 km/h) or to either First or Second gear at speeds under 35 mph (56 km/h). Power Braking

Increasing the engine speed above idle without vehicle movement (such as holding the brake) in a forward or reverse gear causes transmission stall. Continued operation in the stall condition can result in transmission overheat, malfunction or fluid expulsion. Automatic Transmission Operation (E4OD and 4R70W) The E4OD and 4R70W transmissions are electronically controlled four speed automatic transmissions with overdrive. Transmission operation is controlled by the Powertrain Control Module (PCM).

The PCM will automatically adjust transmission operation to make up for varying conditions. Several sensors located on the engine and transmission such as Throttle Position, Engine

[DR08745( ALL)04/95]

*[DR08750( ALL)01/95] *[DR08800( ALL)03/94]

Speed, Vehicle Speed and Transmission Temperature are used by the PCM to shift the transmission into a higher or lower gear when required for the best performance and fuel economy. For example, you may notice that the transmission will upshift to a higher gear more quickly when the vehicle is first driven and has not reached normal operating temperature.

The PCM also controls the transmission’s Torque Converter Clutch to further raise vehicle performance and fuel economy. The Torque Converter Clutch will engage when the transmission operating temperature and other conditions determined by the PCM have been met. Engagement of the clutch may be noted as a decrease in engine speed after an upshift has completed or when the driver has depressed the throttle while driving at a steady road speed.

To help in troubleshooting, the PCM continually performs self-tests on the electronic control system and if any faults are detected, will store them in memory. The Transmission Control Indicator Light (TCIL), which is located on the gearshift lever, may flash steadily if a malfunction has been detected. If the TCIL is flashing, contact your Ford dealer as soon as possible. If this condition persists, damage to the transmission could occur.

NOTE: The word “OFF” located on the end of

the gearshift lever is the transmission control indicator light (TCIL).

Putting Your Vehicle in Gear

Your vehicle’s gearshift is on the steering column. The Transmission Control Switch and indicator light are located on the end of the gearshift lever. You can put the gearshift in any of the several positions.

NOTE: Your vehicle is equipped with a

brake-shift interlock feature. This feature prevents you from shifting from P (Park) unless you have the brake pedal depressed. (The ignition must be in the ON position.) If you cannot shift from P (Park) with the brake pedal depressed:

1. Apply the parking brake.

2. Remove the key.

3.

Insert the key and rotate one position clockwise (ignition in the OFF position).

4. Apply the brake pedal and shift to N

(Neutral). (If the vehicle is shifted to P (Park), you must repeat the previous steps.)

5. Start the vehicle.

If you need to shift out of P (Park) by using the alternate procedure described above, it is possible that a fuse has blown and that your brakelamps may also not be functional. Please refer to the chapter titled Servicing Your F-Series in this Owner Guide for instructions on checking and replacing fuses.

RWARNING

DO NOT DRIVE YOUR VEHICLE UNTIL YOU VERIFY THAT THE BRAKELAMPS ARE WORKING.

R (Reverse)

With the gearshift in the R (Reverse) position, the vehicle will move backward. You should always come to a complete stop before shifting into or out of R (Reverse).

Driving When to use j (Overdrive)

This is the normal driving position. As the vehicle picks up speed, automatic upshifts to second, third and fourth gears will occur when j Overdrive is chosen on the selector and the transmission control switch has not been pressed. The transmission will shift into the correct gear when the right speed is achieved, for the accelerator pedal position you have chosen.

When to use Drive

You will note that there isn’t a drive position on your gearshift indicator. However, you will find a Transmission Control Switch and an indicator light labeled “Overdrive” located on the end of the gearshift lever. Press this switch and the word “OFF” will illuminate on the shift lever knob. With the word “OFF” illuminated, the transmission will operate in gears one through three. Operating in the Overdrive “OFF” mode gives more engine braking than Overdrive and is useful for descending hills or when towing.

To return the transmission to the normal j Overdrive operation, press the transmission control switch again. The Transmission Control Indicator Light will not be illuminated when Overdrive operation resumes. This switch may be used to select O/D ON or O/D OFF any time the vehicle is being driven.

When starting your vehicle, the overdrive system will automatically be in the normal overdrive mode.

If the Transmission Control Indicator Light is flashing on and off steadily, a transmission system malfunction was detected. The transmission will operate in a failure management mode and may have harsh engagements, firm shift feel, or abnormal shift schedule. If this condition persists, damage to the transmission could occur. Contact your dealer as soon as possible.

When to use 2 (Second)

Use 2 (Second) to start-up on slippery roads or to provide additional engine braking on downgrades. This position provides 2 (Second) gear operation only.

When to use 1 (Low)

Use 1 (Low) to provide maximum engine braking on steep downgrades. Upshifts from 1
(Low) can be made by manually shifting to 2
(Second) or j (Overdrive). Selection of 1 (Low) gear provides only low gear operation from start-up. Selection of 1 (Low) while at higher speeds provides a shift to second gear, and a shift to first gear will occur after the vehicle decelerates to the proper speed.

Forced Downshifts To gain extra acceleration in j Overdrive or Drive (O/D OFF), push the accelerator to the floor. The transmission will automatically downshift to the appropriate gear: third, second or first. Power Braking Increasing the engine speed above idle without vehicle movement (such as holding the brake) in a forward or reverse gear causes transmission stall. NOTE: Continued operation in the stall

condition can result in transmission overheat, malfunction or fluid expulsion.

Driving with a Manual Transmission Using the Clutch Make sure the gearshift lever is in the N (Neutral) position and your right foot is holding down the brake pedal. Then press the clutch pedal to the floor with your left foot. Manual transmission vehicles have a starter interlock switch. The starter will not crank until the clutch pedal is fully depressed. Start the engine and allow it to idle for a few seconds. Move the gearshift into 1 (First) or R (Reverse). To move the vehicle, release the clutch slowly and at the same time press down slowly on the accelerator so that the vehicle accelerates. Do not drive with your foot resting on the clutch pedal and do not use the clutch to hold your vehicle at a standstill while waiting on a hill. These actions will seriously reduce clutch life.

Driving with your foot resting on the clutch may cause the vehicle to jerk sharply when pressing or removing your other foot from the accelerator. Shifting the Gears

The gearshift for a manual transmission is mounted on the floor. The gearshift pattern consists of seven positions: Neutral, five forward gears, and Reverse.

5-Speed Overdrive manual transmission shift pattern

Backing up

To shift into R (Reverse):

1. Push the clutch pedal in all the way to the

floor and hold it. If you do not hold the clutch pedal in all the way, you may hear a grinding noise when you shift.

2. Bring your vehicle to a complete stop.

Failure to do so may cause synchronizer teeth damage, reducing the useful life of your transmission.

3. Put the gearshift in Neutral and wait at least 3 seconds before shifting into R (Reverse) to prevent a grinding noise. Do not release the clutch.

4. Push the gearshift all the way to the right

and pull it back into Reverse.

With the 5-speed transmission you can engage R (Reverse) only by moving the gearshift from the left of 3 (Third) and 4 (Fourth) gears before you shift into R (Reverse). This is a special lockout feature that protects you from accidentally shifting into R when you downshift from 5
(Fifth) gear.

5. Once R (Reverse) is engaged, slowly release

the clutch pedal from the floor.

If R (Reverse) is not engaged, continue to push the clutch pedal in while you put the gearshift back into Neutral. Then, release the clutch pedal for a moment and repeat steps 2 through 5.

Upshifting/downshifting

Upshift and Downshift at the speeds that are specified in the charts available for your engine and transmission.

NOTE: Refer to the Diesel Engine Owner’s

Guide Supplement for shift speed information on vehicles equipped with 7.3L diesel engines.

When you slow down or climb a steep hill, always downshift before the engine starts to lose power. Downshifting reduces the chance of stalling and gives your vehicle better acceleration to increase speed again.

When you drive down steep hills, downshifting helps you keep a safe speed and helps prevent unnecessary wear on the brakes.

When you come to a stop, do not downshift through each gear. Disengage the clutch and use the brake as necessary. Downshifting through the gears decreases your vehicle’s fuel economy.

RWARNING

Continued use of a damaged or worn clutch, prolonged clutch slippage or downshifting at excessive speeds can result in a failure of the engine, transmission or clutch components.

Transmission Function

Upshift at the speeds specified in the chart available for your engine and transmission. All forward gears are synchronized allowing you to shift into them with your vehicle in motion. The clutch pedal should be fully depressed when shifting.

NOTE: Shifting during extremely low rpm’s

can result in a momentary audible rattle which disappears as vehicle rpm’s are increased. Shifting at higher speeds will eliminate this sound.

Parking

To park your vehicle, apply the service brake pedal, and shift into N (Neutral) while still maintaining pressure on the service brake. Set the parking brake fully. Shift into first and turn off the ignition.

RWARNING

Do not park your vehicle in Neutral, it may move unexpectedly and injure someone. Use 1 (First) gear and set the parking brake fully.

When the transfer case is in the N (Neutral) position, the engine and transmission are disconnected from the rest of the driveline. Therefore, the vehicle is free to roll even if the automatic transmission is in P (Park) or the manual transmission is in gear.

RWARNING

Do not leave the vehicle unattended with the transfer case in the N (Neutral) position. Always set the parking brake fully and turn off the ignition when leaving the vehicle.

Steering Your Vehicle Your vehicle comes with power steering. Power steering uses energy from the engine to help steer your vehicle. If the amount of effort needed to steer your vehicle changes at a constant vehicle speed, have the power steering system checked. If the power steering system breaks down (or if the engine is turned off), you can steer the vehicle manually but it takes more effort. Never hold the steering wheel to the extreme right or left for more than five seconds if the engine is running. This can damage the power steering pump. NOTE: After any severe impact such as

striking large potholes, sliding into curbs on icy roads, or a collision involving the front end, observe the steering wheel alignment. If the spokes of the steering wheel seem to be in a different position while going straight down the road, have the front suspension and steering checked for possible damage.

Four-Wheel Drive (4WD) System (If equipped) When you select the 4WD mode, your light truck uses all four wheels to power itself. This increases traction, enabling you to drive your 4x4 over terrain and road conditions two-wheel drive vehicles cannot.

Power is supplied to all four wheels through a transfer case that allows you to select four-wheel drive when necessary. Methods for engaging and disengaging 4WD and low range will depend on which system your vehicle has. 4x4 Systems — Lever Operated

The lever operated transfer case can be placed into four positions. The 2H position is the two-wheel drive position in which power is delivered only to the rear axle. The 4H position provides four-wheel drive with power delivered to the front and rear axles for increased traction. The 4L position provides four-wheel drive with power delivered to the front and rear axles when the above average power is required at reduced speeds. In the N (neutral) position, there is no power delivered to either axle.

When the transfer case is in the N (Neutral) position, the engine and transmission are disconnected from the rest of the driveline. Therefore, the vehicle is free to roll even if the automatic transmission is in P (Park) or the manual transmission is in gear.

Four-wheel drive operation (4H or 4L) on dry pavement is not recommended. Operating the vehicle in four-wheel drive on dry pavement will increase tire wear, decrease fuel economy, and make four-wheel drive disengagement difficult for the transfer case.

NOTE: All transfer cases on F-350 4x4 trucks

are equipped with an opening for a power take-off (PTO). If this opening is used for a transfer case mounted PTO, additional transfer case lubricant is required. Refer to the Refill Capacities section for lubricant fill requirements. Vehicles equipped with an E4OD automatic transmission and a 7.3L diesel engine will require exhaust modification for PTO clearance. For vehicles equipped with an E4OD automatic transmission: If a transfer case mounted PTO is operated with the transfer case shift lever in neutral, a Vehicle Speed Sensor Self-test error may be set in the Powertrain Control Module (PCM) causing the transmission to function abnormally, and the Transmission Control Indicator Light (TCIL) may flash on and off repeatedly. Normal transmission function should return when the transfer case has been engaged and the vehicle is driven. If the TCIL continues to flash or the transmission continues to operate abnormally contact your Ford dealer as soon as possible.

To shift from 2H to 4H:

Stop the vehicle and move the transfer case shift lever straight back to the 4H position, the automatic locking hubs will engage when the vehicle is driven. When the automatic locking hubs are engaged, shifts between 2H and 4H may take place at any speed. q The automatic locking hubs may disengage in

2H if the vehicle’s direction is momentarily reversed, or the vehicle is allowed to roll slightly in the opposite direction. If a grinding noise occurs when shifting from 2H to 4H while the vehicle is moving, one or both of the automatic locking hubs have been disengaged and the transfer case shift lever should be switched back to the 2H position. To shift back into 4H, stop the vehicle and move the transfer case shift lever straight back to the 4H position.

q When the vehicle is stopped while in 4H and

the vehicle’s direction is reversed from the previous direction, the automatic locking hubs momentarily disengage and then re-engage. The automatic locking hubs may click as they automatically engage in the new direction.

To shift from 4H to 2H: Move the transfer case shift lever straight forward to the 2H position. This can be done at any speed. To disengage the automatic locking hubs, operate the vehicle in 2H in the opposite direction for approximately 10 feet (3 meters). For example:

If you were driving the vehicle forward in 4H, the automatic locking hubs will disengage the next time the vehicle is driven in reverse in 2H for approximately 10 feet (3
meters). If you were driving the vehicle in reverse in 4H, the automatic locking hubs will disengage the next time the vehicle is driven forward in 2H for approximately 10 feet (3
meters).

If it is difficult to shift into either 4H or 4L, it may be necessary to let the vehicle roll slightly and/or turn off the engine (particularly on vehicles equipped with automatic transmissions). 4x4 SYSTEMS-TOUCH DRIVE The Touch Drive 4x4 system functions in three modes. In Two Wheel Drive mode, power is delivered only to the rear axle at normal road speed. The 4H position provides four-wheel drive with power delivered to the front and rear axles for increased traction. The 4L position provides four-wheel drive with power delivered to the front and rear axles when the above average power is required at reduced speeds. Four wheel drive operation (4x4 or 4x4 LOW RANGE) on dry pavement is not recommended. Operating the vehicle in four-wheel drive on dry pavement will increase noise, vibration, tire wear, decrease fuel economy, and make four-wheel drive disengagement difficult for the transfer case.

— The initial shift from two-wheel drive to 4x4
while the vehicle is moving can cause some momentary clunk and ratcheting sounds. This is the front drivetrain coming up to speed and the automatic locking hubs engaging and is not a cause for concern.

— Because of possible damage to powertrain components, never shift from Two-Wheel Drive to 4x4 with the rear wheels slipping.

To shift from 4x4 to Two-Wheel Drive:

Push the 4x4 button; the 4x4 lamp on the instrument cluster will go out indicating the vehicle is in Two-Wheel Drive. This can be done at any speed. To disengage the automatic locking hubs, operate the vehicle in Two-Wheel Drive in the opposite direction for approximately 10 feet (3 meters) in a straight line.

For example:

If you were driving the vehicle forward in 4x4, the automatic locking hubs will disengage the next time the vehicle is driven in reverse in Two-Wheel Drive for approximately 10 feet (3 meters) in a straight line. If you were driving the vehicle in reverse in 4x4, the automatic locking hubs will disengage the next time the vehicle is driven forward in Two-Wheel Drive for approximately 10 feet (3 meters) in a straight line.

Operating in two-wheel drive mode with the hubs locked increases fuel consumption, noise, vibration, and wear. For prolonged two-wheel drive operation on dry pavement, disengagement of the automatic locking hubs, which is not required for two-wheel drive operation, stops all

Driving Off Road with 4-Wheel Drive Most vehicles with four-wheel drive are especially equipped for driving on sand, snow, mud, or rough terrain and have operating characteristics that are somewhat different from conventional vehicles, both off and on the road. The driving tips below will help you learn to use four-wheel drive. q Do not use 4WD LOW on dry, hard-surfaced

roads.

Special maintenance procedures are necessary after operating with drive components in water.

q Manual locking hubs must be in LOCK

position before shifting into four-wheel drive. When using four-wheel drive, maintain steering wheel control at all times, especially in rough terrain. Since sudden changes in terrain can result in abrupt steering wheel motion, make sure you grip the steering wheel rim from the outside. Do not grip the spokes. Drive cautiously to avoid vehicle damage from concealed objects such as rocks and stumps. Know the terrain or examine maps of the area in question before driving. Map out your route beforehand. To maintain steering and braking control of your vehicle, you must have all four tires on the ground, and they must be rolling, not sliding or spinning. Transmission upshift in 4x4 with transfer case in 4L may be quite firm due to large total gear reduction. This condition is normal. Sand When driving over sand, try to keep all four wheels of the vehicle on the most solid area of the trail. Do not reduce the tire pressures but shift to a lower gear and drive steadily through the terrain. Apply accelerator slowly and avoid spinning the wheels. Mud and Water When driving through water, determine the depth; avoid water higher than the bottom of the hubs (if possible) and proceed slowly. If the ignition system gets wet, the vehicle may stall. Once through water, always try the brakes. Wet brakes do not stop the vehicle as effectively as dry brakes. Drying can be improved by moving your vehicle slowly, while applying light pressure on the brake pedal.

After driving through mud, clean off residue stuck to rotating driveshafts and tires. Excess mud stuck on tires and rotating driveshafts causes an imbalance which could damage drive components.

NOTE: If the transmission and transfer case is submerged in water, their fluids should be checked and changed, if necessary.

NOTE: Refer to the Diesel Engine Owner’s

Guide Supplement for driving through deep water information.

Additional Special Driving Instructions for 4-Wheel Drive Vehicle Operators Driving on Hill or Slope Terrain

When driving on a hill, it may be necessary to travel diagonally up or down. Avoid driving crosswise or turning on steep slopes, you could lose traction and slip sideways. Drive straight up, straight down or avoid the hill completely. Know the conditions on the other side of a hill before driving over the crest.

When climbing a steep hill, start in a lower gear, rather than finding it necessary to downshift from a higher gear after the ascent has started. This reduces strain on the engine and the possibility of stalling.

When descending a steep hill avoid sudden braking. Rapid pumping of the brake pedal will help slow the vehicle and still maintain steering control.

Driving on Snow or Ice

A four-wheel drive vehicle has advantages over two-wheel drive vehicles in snow and ice but can skid like any other vehicle. If so equipped, keep the vehicle in four-wheel drive if icy or slippery conditions exist.

Avoid sudden applications of power and quick changes of direction on snow or ice. Apply the accelerator slowly and steadily when starting from a full stop.

All utility-type and Four-Wheel Drive vehicles have special design and equipment features to make them capable of performing in a wide variety of off-road applications. Specific design characteristics give them higher centers of gravity than ordinary passenger cars.

RWARNING

All utility and four-wheel drive vehicles are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns or abrupt maneuvers in these vehicles.

Brakes Front Disc Brakes

Rear Drum Brakes

The rear drum brakes are self-adjusting. Automatic adjustment occurs when the brakes are applied while “backing up.” If normal operation does not include much backing, adjust the brakes when they seem “low,” using the procedure under If Brakes Do Not Grip Well or Pedal is Low in this chapter. Rear Disc Brakes (F-Super Duty and F-Series Stripped Chassis Only)

The rear disc brakes are self-adjusting. They do not require service other than periodic lubrication of the caliper slide rails and inspection for pad wear. Hydraulic Power Brakes

The hydraulic brake system is made up of two independent hydraulic circuits. One hydraulic circuit supplies fluid to the front disc brakes and the other hydraulic circuit supplies fluid to the rear drum brakes. These two circuits are supplied by a common hydraulic brake fluid reservoir, with a fluid level sensor.

The brake light in the instrument cluster will light for low brake fluid in the common brake fluid reservoir.

RWARNING

An increase in pedal travel will result in reduced braking capability. The brake system should be checked immediately.

Rear Anti-lock Brakes

Except for F-Super Duty and F-Series Commercial and Motorhome Stripped Chassis, F-Series Light Trucks are equipped with a Rear Antilock Brake System. This system prevents at least one and often both rear wheels from locking up when the brakes are applied in a panic stop, for example.

Even with the Anti-lock Brake System, you should be careful when braking. Front brake lock up on any surface, even on smooth pavement causes loss of steering control. Heavy braking on roads with loose surfaces such as snow or gravel, or severe pavement irregularities could also cause you to lose steering control of your vehicle.

RWARNING

If the anti-lock brake system warning light remains on or comes on while driving, have the braking system checked by a qualified service technician as soon as possible.

NOTE: If a fault occurs in the anti-lock

system, and the brake warning light is not lit, the anti-lock system is disabled but normal brake function remains operational.

If Brakes Do Not Grip Well or Pedal is “Low” (F-150/350 Only)

If brakes do not grip well, it may indicate the rear drum brakes need adjustment. To do this, drive the vehicle in reverse at 5 mph (8 km/h) on level, dry pavement. Stop the vehicle by firmly applying the brakes. Repeat this procedure four or five times.

If during normal operation the brake pedal seems “low”, it may indicate the need for a brake system inspection and/or service. You should have your brakes checked as soon as possible.

Occasional brake squeal during light to moderate stops does not affect the function of the brake system and is normal. However, if the squeal becomes annoyingly loud or increases significantly in frequency of occurrence, return the vehicle to your dealer for inspection.

RWARNING

Modifications to the suspension spring rates and/or vehicle ride height may adversely affect vehicle stopping ability.

If Brakes Pull q Check tire pressure q Perform the self-adjustment procedure

described under If Brakes Do Not Grip Well or Pedal is “Low.”

If pull occurs during the first 500 miles (800 km), make 10 moderately fast stops from 40 mph (65 km/h) and then perform the self-adjustment procedure above. It may be necessary to repeat this operation to properly seat new brake linings and pads. Stopping Distances

Stopping distances vary with different loads and driving conditions. Use caution when encountering new conditions and acquaint yourself with vehicle performance. Take full advantage of engine braking power when slowing down.

Applying the Brakes

Apply the brake pedal gradually. Use the “squeeze” technique — push on the brake pedal with a steadily increasing force. This allows the wheels to continue to roll while you are slowing down, which lets you steer properly.

RWARNING

Do not drive with your foot resting on the brake pedal. This will increase your vehicle’s stopping distance and may also cause brake damage.

RWARNING

If you are driving down a long or steep hill, shift to a lower gear. Do not apply your brakes continuously, as they may overheat and become less effective.

Using the Parking Brake The parking brake should be used whenever you park your vehicle.

The parking brake pedal is suspended just below the bottom of the instrument panel to the left of service brake and/or clutch pedals. To set the parking brake while parking your vehicle, press the brake pedal with your right foot and hold it while you push the parking brake pedal down firmly and fully with your left foot.

Parking Brake

RWARNING

When parking, do not use the gearshift in place of the parking brake. Turn the key to LOCK whenever you leave your vehicle. Always set the parking brake fully and make sure that the gearshift is securely latched in P (Park) (automatic transmission) or in 1 (First) (manual transmission). Never leave your vehicle unattended while it is running. If you do not take these precautions, your vehicle may move unexpectedly and injure someone.

When the transfer case is in the N (Neutral) position, the engine and transmission are disconnected from the rest of the driveline. Therefore, the vehicle is free to roll even if the automatic transmission is in P (Park) or the manual transmission is in gear.

RWARNING

Do not leave the vehicle unattended with the transfer case in the N (Neutral) position. Always set the parking brake fully and turn off the ignition when leaving the vehicle.

To release the parking brake, press the service brake pedal with your right foot and pull the parking brake release lever.

RWARNING

If the parking brake is fully released, but the Brake System light remains on, have the brakes checked immediately. They may not be working properly.

The parking brake is not designed to stop a moving vehicle, but you can use the parking brake to stop your vehicle in an emergency if the normal brakes fail. However, since the parking brake applies only the rear brakes, the stopping distance will increase greatly and the handling of your vehicle will be adversely affected. Driving Under Special Conditions Tips for Safe Driving

As with any new vehicle, yours may drive and handle differently from your previous vehicle. Use care until you become accustomed to its various features and driving characteristics.

Operate your vehicle within reasonable limits. Sudden acceleration, deceleration, turning, or combinations of these maneuvers can cause a vehicle to behave differently than anticipated.

Speed limiter

All models are equipped with an electronic engine control system (EEC) which limits the maximum engine speed and thus road speed in top gear. Vehicle operation is normal since the controlled maximum speed is above posted highway speeds in North America. Driving in Bad Weather

Slippery roads

Drive cautiously on wet or snowy roads: q Do not quickly move the steering wheel

unless necessary.

q Drive slower than you normally would. q Give your vehicle more distance to stop. q To stop on ice, shift to Neutral below 10 mph

(16 km/h) and gently pump brakes. (Except with 4WAL)

q Consider using one of the lower gears.

For 4x4 vehicles, engage 4WD, and try to drive slowly away.

RWARNING

To avoid losing control on slippery roads, do not downshift into Low with the automatic transmission when moving faster than 20 mph (32 km/h). Do not downshift into First with the manual transmission when moving faster than 5 mph (8 km/h).

RWARNING

The rear antilock brake system may not prevent brake lock-up on extremely slippery surfaces. Rear brake lock-up may also occur while driving in four-wheel drive because the transfer case couples the front and rear axles together.

Traction-Lok Rear Axle (If equipped)

This axle provides added drive away traction on slippery surfaces, particularly when one or more wheels are on a surface with poor traction.

Extended use of other than matching size tires on a Traction-Lok rear axle could result in a permanent reduction in effectiveness. This loss of effectiveness does not affect normal driving and should not be noticeable to the driver.

RWARNING

To avoid injury, never run the engine with one wheel off the ground, such as when changing a tire.

High water

Never attempt to cross water that is fast flowing or of unknown depth.

Do not drive through flooded areas unless you are sure that the water is below the bottom of the wheel hubs.

If you must drive through high water, drive slowly. You may have limited traction or wet brakes, so allow extra stopping distance because your vehicle will not stop as quickly as usual.

*[DR27975( ALL)05/95]

After you drive through the standing water, apply your brakes gently several times as your vehicle moves slowly. This helps to dry the brakes.

NOTE: If the transmission and transfer case is submerged in water, their fluids should be checked and changed, if necessary.

NOTE: All rear axle lube quantities must be

replaced every 100,000 miles (160,000 km) or if the axle has been submerged in water. Otherwise, the lube should not be checked or changed unless a leak is suspected or repair required.

Rocking the vehicle

For 4x4 vehicles, engage 4WD LOW, when the vehicle gets stuck and try to drive away.

If your vehicle gets stuck (for example, in mud or snow), you may rock it out of the spot. Shift in a steady rhythm between forward and reverse gears. Allow the transmission to fully engage, then press lightly on the accelerator. Do not rock the vehicle for more than a few minutes. This may overheat the engine and transmission, causing damage to both. In addition, other vehicle systems and components may also be damaged.

RWARNING

Do not spin the wheels at over 35 mph (56 km/h). The tires may fail and injure a passenger or bystander.

Driving With a Heavy Load There are limits to the amount of weight your vehicle can carry or tow. The total weight of your vehicle, plus the weight of the passengers and cargo, should never be more than the Gross Vehicle Weight Rating (GVWR). Also, the weight that your vehicle carries over the front axle and rear axle should never be more than the Gross Axle Weight Rating (GAWR) for the respective axle. The weight limits of your vehicle’s tires affect the GVWR or GAWR limitations. Usage of replacement tires with higher weight limit than originals does not increase GVWR or GAWR. Usage of lower capacity replacement tires may lower GVWR and GAWR limitations.

RWARNING

If the GVWR or the GAWR specified on the Safety Compliance Certification Label is exceeded, your vehicle may be damaged or you may lose control and injure someone.

Heavy duty front suspension package (option) This optional front suspension package is designed to handle the additional loads that will be imposed on the vehicle by adding aftermarket equipment, such as a snowplow. Refer to the Safety Compliance Certification Label for details. Securing loads in cargo area To prevent damage to the pickup box and cab, secure any movable cargo pieces using ropes or straps and the tie down holes in the stake pockets of the steel pickup box or the tie-down bars in the flareside pickup box.

Vehicle/Trailer Loads All vehicles may tow a Class I trailer provided the Gross Combined Weight (GCW) is less than or equal to the GVWR shown on the Safety Compliance Certification Label. For heavier trailer applications, refer to the towing information found later in this chapter. Trailer Towing (may require trailer tow option package) Towing a trailer puts additional loads on your vehicle’s engine, transmission, axle, brakes, tires and suspension. For your safety and for the good of your vehicle, use the right equipment for the type of trailer you tow. If your trailer is equipped with electric brakes, auxiliary battery, or back-up lamps, the optional 7 wire trailer towing electrical hook-up will be required on the vehicle. Your trailer towing capability will vary based on the standard and optional equipment on your vehicle. Refer to the following Vehicle Loading/Towing Information and the Trailer Towing Tables to determine the specific towing capability of your vehicle.

Stay within the load limits when you tow.

q Carefully and thoroughly prepare your

vehicle for towing, making sure to use the right equipment and to attach it properly. (See Preparing to Tow in this chapter.)

q Use extra caution when driving your vehicle while you tow. (See Driving while you tow in this chapter.) Service your vehicle more frequently if you tow a trailer. (See Servicing your vehicle if you tow in this chapter.)

Do not tow a trailer until your vehicle has been driven at least 500 miles (800 km). Vehicle Loading/Towing Information Your vehicle’s load capacity is designated by weight, not volume, so you cannot necessarily use all available space with large or heavy loads. Maximum safe vehicle weights as well as tire, rim sizes and inflation pressures are specified for your vehicle at the assembly plant on the Safety Compliance Certification Label. The Certification Label is located on the left front door lock facing or the door latch post pillar.

Trucks, unlike passenger cars, are basically custom vehicles designed to carry a load. Most owners start with a base vehicle and add production and dealer installed and/or aftermarket components to suit their tastes and purposes. Even trucks that are purchased for personal transportation only are likely to have considerable optional equipment, such as step bumpers and light bars, for example.

RWARNING

Passengers should not be allowed to ride in the cargo area. Persons not riding in a seat with a fastened seat belt are much more likely to suffer serious injury in a collision. Cargo should always be secured to prevent it from shifting and causing damage to the vehicle or harm to passengers.

Each additional item of equipment affects how much cargo a vehicle can carry. If a vehicle is overloaded, performance will suffer and service concerns may arise.

q GAWR (Gross Axle Weight Rating) q GCWR (Gross Combined Weight Rating) q Maximum Trailer Weight Rating q Maximum Trailer Weight q Trailer Weight Range Base Curb Weight

The Base Curb Weight is the weight of the vehicle including fuel, coolants, lubricants, emergency tools, spare wheel and tire. It also includes any equipment that is standard on that model. It does not include passengers, cargo or optional equipment installed by factory, dealer, aftermarket supplier or customer.

Payload

Payload is the combined, maximum allowable weight of cargo, occupants and optional equipment that the truck is designed to carry. It is Gross Vehicle Weight Rating minus the base curb weight.

Gross Vehicle Weight (GVW)

If you add base curb weight and the weight of a load (including passengers, cargo and optional equipment) being carried at a particular time, you get the Gross Vehicle Weight (GVW).

It is important to remember that GVW is not a limit or a specification. If an owner loads up a vehicle and weighs it, that’s the GVW at that moment. If the owner piles on more of a load and weighs it again, that becomes the GVW...until such time as the vehicle is unloaded.
