8. After the Neutral (N) button has been released the transfer case will shift to the position identified by the selector switch. 9. Shift automatic transmission into P (Park). Items 1 through 5 are requirements that must be NOTE: met prior to depressing the Neutral (N) selection button, and must continue to be met until 1 second elapses and the shift has been completed. If any of these requirements (with the exception of 3 - key ON) are not met prior to depressing the Neutral (N) button or are no longer met during the 1 second time, then all of the mode position indicator lights will flash continuously until all require- ments are met or until the Neutral (N) button is released. NOTE: The ignition key must be ON for a shift to take place and for the position indicator lights to be operable. If the key is not ON, the shift will not take place and no position indicator lights will be on or flashing.
316 STARTING AND OPERATING
NOTE: Flashing neutral (N) position indicator light indicates that shift requirements have not been met.
WARNING!
You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move despite the transmission position. The parking brake should always be applied when the driver is not in the vehicle.
CAUTION!
• Do not use a bumper mounted clamp-on tow bar on your vehicle. The bumper face bar will be damaged. • Do not disconnect the rear driveshaft because fluid will leak from the transfer case and fluid loss will damage internal parts.
DRIVING OFF-ROAD Care should be taken when attempting to climb steep hills or driving diagonally across a hill or slope. If natural obstacles force you to travel diagonally up or down a hill, choose a mild angle and keep as little side tilt as possible. Keep the vehicle moving and make turns slowly and cautiously. If you must back down a hill, back straight down using REVERSE gear. Never back down in NEUTRAL, or diagonally across the hill. When driving over sand, mud, and other soft terrain, shift to low gear and drive steadily. Apply the accelerator slowly to avoid spinning the wheels. DO NOT REDUCE the tire pressures for this type of driving.
STARTING AND OPERATING 317
NOTE: After off-road usage, particularly in sand or mud, inspect the underside of the vehicle for accumu- lated dirt at the propeller shaft, axles, U-joints, brake rotors and calipers. Use a hose to clean off any accumulation of dirt or mud. Check the exhaust system and all exposed components for any sign of damage. If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for im- pacted material. Impacted foreign material can cause a wheel imbalance. Removing the foreign material from the wheels will correct the situation.
318 STARTING AND OPERATING
TRACTION When driving on wet or slushy roads, it is possible for a wedge of water to build up between the tire and road surface. This is known as hydroplaning and may cause partial or complete loss of vehicle control and stopping ability. To reduce this possibility, the following precau- tions should be observed: 1. Slow down during rainstorms or when roads are slushy. 2. Slow down if road has standing water or puddles. 3. Replace tires when tread wear indicators first become visible. 4. Keep tires properly inflated. 5. Maintain sufficient distance between your vehicle and the car in front to avoid a collision in a sudden stop.
EQUIPMENT IDENTIFICATION PLATE The equipment Identification Plate is located on the hood inner surface. The following information about your vehicle is dis- played on this plate: Model, Wheelbase, Vehicle Identifi- cation Number, Truck Order Number, and code numbers with descriptions of all production and special equip- ment on the truck as shipped from the factory. NOTE: Always refer to the Equipment Identification Plate When Ordering Parts.

HAZARD WARNING LIGHTS The Hazard Warning switch is mounted on the top of the steering column as shown in the illustration.
To engage the Hazard Warning lights, depress the button on the top of the steering column. When the Hazard Warning switch is activated, all directional turn signals
will flash off and on to warn oncoming traffic of an emergency. Push the button a second time to turn off the flashers. This is an emergency warning system and should not be used when the vehicle is in motion. Use it when your vehicle is disabled and is creating a safety hazard for other motorists. When you must leave the vehicle to seek assistance, the Hazard Warning lights will continue to operate even though the ignition switch is OFF. NOTE: With extended use, the Hazard Warning lights may discharge your battery.
ADDING FUEL The fuel tank filler tube has a restricting door about 2
inches (50 mm) inside the opening. If using a portable fuel container, it should have a flexible nozzle long enough to force open the restricting door.WARNING!
A fire may result if gasoline is pumped into a portable container that is in a vehicle or on a truck bed. You could be burned. Always place gas contain- ers on the ground while filling.
WHAT TO DO IN EMERGENCIES 321
WARNING!
Remove the gas cap slowly to prevent fuel spray from the filler neck which may cause injury. The volatility of present gasolines may cause a build up of pressure in the fuel tank that may increase while you drive. This pressure can result in a spray of gasoline and/or vapors when you remove the cap from a hot vehicle. Removing the cap slowly allows the pressure to vent and prevents fuel spray. Never allow any lit smoking materials near the vehicles while removing the cap or filling the tank. Never add fuel to the vehicle when the engine is running.

CHANGING A FLAT TIRE
Removing The Spare Tire Remove the spare tire before attempting to jack the truck. Attach the wheel wrench to the jack extension tube. Insert the tube through the access hole between the lower tailgate and the top of the bumper and into the winch mechanism tube. Rotate the wheel wrench handle coun- terclockwise until the spare tire is on the ground with enough cable slack to allow you to pull it out from under the vehicle. When the spare is clear, tilt the retainer at the end of the cable and pull it through the center of the wheel.
It is recommended that you stow the flat or spare to avoid tangling the loose cable. NOTE: The winch mechanism is designed for use with the jack extension tube only. Use of an air wrench or other power tools is not recommended and can damage the winch.
Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a vehicle that is on a jack. Never start or run the engine while the vehicle is on a jack. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift.
Do not raise this vehicle using a bumper jack. The jack is designed as a tool for changing tires on this vehicle only. It is not recommended that the jack be used for service purposes or to lift more than one wheel at a time.
WHAT TO DO IN EMERGENCIES 327
Preparations Park the vehicle on a firm level surface, avoiding ice or slippery areas. Set the parking brake and place the gear selector in PARK (automatic transmission) or REVERSE (manual transmission). On four-wheel drive vehicles, shift the transfer case to the “4L” position.
WARNING!
Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid the danger of being hit when operating the jack or changing the wheel.
328 WHAT TO DO IN EMERGENCIES
• Turn on the Hazard Warning Flasher.

• Connect the jack tube extension and wheel wrench. Before raising the wheel off the ground, make sure that the jack will not damage surrounding truck parts and adjust the jack position as required.
332 WHAT TO DO IN EMERGENCIES
If the 2500/3500 bottle jack will not lower by NOTE: turning the dial (thumb wheel) by hand, it may be necessary to use the jack drive tube in order to lower the jack. 4. By rotating the wheel wrench clockwise, raise the vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make the vehicle unstable and cause an accident. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install the spare wheel and wheel nuts with the cone shaped end of the nuts toward the wheel on 2500/3500 single rear wheel (SRW) models. On 3500 dual rear wheel models (DRW) the lug nuts are a two piece assembly with a flat face. Lightly tighten the nuts. To avoid risk of forcing the vehicle off the jack, do not fully tighten the nuts until the vehicle has been lowered. 6. Using the wheel wrench, finish tightening the nuts using a crisscross pattern. Correct nut tightness is 135 ft. lbs. (183 N·m) torque for 2500/3500 single rear wheel (SRW) models and 145 ft. lbs. (197 N·m) for 3500 dual rear wheel models. If in doubt about the correct tightness, have them checked with a torque wrench by your dealer or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or hard stop could injure someone in the vehicle. Always stow the jack parts and the extra tire and wheel in the places provided.
7. Install wheel center cap and remove wheel blocks. Do not install chrome or aluminum wheel center caps on the spare wheel. This may result in cap damage. 8. Lower the jack to its fully closed position. If the bottle jack will not lower by turning the dial (thumb wheel) by hand, it may be necessary to use the jack drive tube in order to lower the jack. Stow the replaced tire, jack, and tools as previously described. 9. Adjust the tire pressure when possible.
WHAT TO DO IN EMERGENCIES 333
NOTE: Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated wheel nuts. Hub Caps The hub caps must be removed before raising the vehicle off the ground. For 2500/3500 single rear wheel (SRW) models, use the blade on the end of the lug wrench to pry the cap off. On 3500 models with dual rear wheels (DRW), you must first remove the hub caps. The jack handle driver has a hook at one end that will fit in the pry off notch of the rear hub caps. Position the hook and pull out on the ratchet firmly. The cap should pop off. The wheel skins can now be removed. For the front hub cap on 3500
models use the blade on the end of the lug wrench to pry the caps off. The wheel skin can now be removed.334 WHAT TO DO IN EMERGENCIES
You must use the flat end of the lug wrench to pry off the wheel skins. Insert the flat tip completely and using a back and forth motion, loosen the wheel skin. Repeat this procedure around the tire until the skin pops off. Replace the wheel skins first using a rubber mallet. When replacing the hub caps, tilt the cap retainer over the lugnut bolt circle and strike the high side down with a rubber mallet. Be sure that the hub caps and wheel skins are firmly seated around the wheel. 8-Stud — Dual Rear Wheels Dual wheels are flat mounted, center piloted. The lug nuts are a two piece assembly. When the tires are being rotated or replaced, clean these lug nuts and add 2 drops of oil at the interface between the hex and the washer.
Slots in the wheels will assist in properly orienting the inner and outer wheels. Align these slots when assem- bling the wheels for best access to the tire valve on the inner wheel. The tires of both dual wheels must be completely off the ground when tightening to insure wheel centering and maximum wheel clamping.
Dual wheel models require a special heavy-duty lug nut tightening adapter (included with the vehicle) to cor- rectly tighten the lug nuts. Also, when it is necessary to remove and install dual rear wheels, use a proper vehicle lifting device. NOTE: When installing a spare tire as part of a dual rear wheel end combination, the tire diameter of the two individual tires must be compared. If there is a significant difference, the larger tire should be installed in a front location. Correct direction of rotation for dual tire instal- lations must also be observed. These dual rear wheels should be tightened as follows:
WHAT TO DO IN EMERGENCIES 335
336 WHAT TO DO IN EMERGENCIES
1. Tighten the wheel nuts in the numbered sequence to a snug fit. 2. Retighten the wheel nuts in the same sequence to the torques listed in the table. Go through the sequence a second time to verify that specific torque has been achieved. Retighten to specifications at 100 miles (160
km) and after 500 miles (800 km). It is recommended that wheel stud nuts be kept torqued to specifications at all times. Torque wheel stud nuts to specifications at each lubrication interval. Wheel Nuts All wheel nuts should be tightened occasionally to elimi- nate the possibility of wheel studs being sheared or the bolt holes in the wheels becoming elongated. This is especially important during the first few hundred miles of operation to allow the wheel nuts to become properly set. All nuts should first be firmly seated against thewheel. The nuts should then be tightened to recom- mended torque. Tighten the nuts to final torque in increments. Progress around the bolt circle, tightening the nut opposite to the nut just previously tightened until final torque is achieved. Recommended torques are shown in the following chart. Disc Wheels

JUMP-STARTING You should not try to start your vehicle by pushing or towing. Vehicles equipped with an automatic transmis- sion cannot be started this way and pushing or towing a vehicle equipped with a manual transmission may over- heat and damage the catalytic converter. Also, there is a greater risk of an accident when a vehicle is being pushed or towed. If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly, so follow this procedure carefully.
Attach the wheel wrench to the extension tube. Rotate the winch mechanism until the wheel is drawn into place against the underside of the vehicle. Continue to rotate until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire several times to be sure it is firmly in place.HOISTING A conventional floor jack may be used at the jacking locations, refer to the graphics that show jacking loca- tions. However, a floor jack or frame hoist must never be used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential housing of a loaded truck or damage to your vehicle may result.
338 WHAT TO DO IN EMERGENCIES
WARNING!
Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or clothing. Don’t lean over battery when attaching clamps or allow the clamps to touch each other. If acid splashes in eyes or on skin, flush contaminated area immedi- ately with large quantities of water. A battery generates hydrogen gas which is flam- mable and explosive. Keep flame or spark away from the vent holes. Do not use a booster battery or any other booster source that has a greater than 12 volt system, i.e. Do not use a 24 volt power source.
Check the Battery Test Indicator (If Equipped). If a yellow or bright colored dot is visible in the indicator (if equipped), DO NOT jump-start the battery.
If the indicator (if equipped) is dark or shows a green dot, proceed as follows: 1. Remove all metal jewelry such as watch bands or bracelets which might make an unintended electrical contact. 2. Park the booster vehicle within cable reach but with- out letting the vehicles touch. Set the parking brake on
both vehicles, place the automatic transmission in Park or the manual transmission in Neutral, and turn the ignition OFF. 3. Turn off the heater, radio, and all unnecessary electri- cal loads. 4. Connect one end of a jumper cable to the positive terminal of the booster battery. Connect the other end of the same cable to the positive terminal of the discharged battery.
WARNING!
Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result.
WHAT TO DO IN EMERGENCIES 339
340 WHAT TO DO IN EMERGENCIES
5. Connect the other cable, first to the negative terminal of the booster battery and then to the engine of the vehicle with the discharged battery. Make sure you have a good contact on the engine.
WARNING!
• Do not connect the cable to the negative post of the discharge battery. The resulting electrical spark could cause the battery to explode. • During cold weather when temperatures are be- low freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump starting because the battery could rupture or explode. The battery temperature must be brought up above freezing point before attempting jump start.
6. Start the engine in the vehicle which has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery. 7. When removing the jumper cables, reverse the above sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in: 1. Personal injury caused by electrolyte squirting out the battery vent; 2. Personal injury or property damage due to battery explosion; 3. Damage to charging system of booster vehicle or of immobilized vehicle.
FREEING A STUCK VEHICLE If vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the gear selector rhythmically between DRIVE and REVERSE, while applying slight pressure to the accelerator. In general, the least amount of accelerator pedal pressure to maintain the rocking motion without spinning the wheels or racing the engine is most effective. Racing the engine or spinning the wheels, due to the frustration of not freeing the vehicle, may lead to transmission over- heating and failure. Allow the engine to idle with the transmission selector in NEUTRAL for at least one minute after every five rocking-motion cycles. This will minimize overheating and reduce the risk of transmis- sion failure during prolonged efforts to free a stuck vehicle.
WHAT TO DO IN EMERGENCIES 341
EMERGENCY TOW HOOKS — IF EQUIPPED Your vehicle may be equipped with emergency tow hooks.
WARNING!
Chains are not recommended for freeing a stuck vehicle. Chains may break, causing serious injury or death.
WARNING!
Stand clear of vehicles when pulling with tow hooks. Tow straps and chains may break, causing serious injury.
342 WHAT TO DO IN EMERGENCIES
CAUTION!
4-Wheel- Drive Vehicles
Tow hooks are for emergency use only, to rescue a vehicle stranded off road. Do not use tow hooks for tow truck hookup or highway towing. You could damage your vehicle.
CAUTION!
To avoid damage to the transfer case while towing, always use one of the following methods.
TOWING A DISABLED VEHICLE Proper towing or lifting equipment is required to prevent damage to your vehicle. Use only tow bars and other equipment designed for the purpose, following equip- ment manufacturer’s instructions. Use of safety chains is mandatory. Attach a tow bar or other towing device to the main structural members of the vehicle—not to bumpers or associated brackets. State and local laws applying to vehicles under tow must be observed.
The manufacturer recommends towing with all wheels OFF the ground. Acceptable methods are to tow vehicle on a flatbed or with one end of vehicle raised and the opposite end on a towing dolly. 2–Wheel- Drive Vehicles Provided that the transmission is operable, tow with the transmission in Neutral and the ignition key in the OFF position along with the front wheels raised and the rear wheels on the ground. Speed must not exceed 30 mph (50
km/h) and distance must not exceed 15 miles (25 km).CAUTION!
Towing faster than 30 mph (50 km/h) or for more than 15 miles (25 km) can cause severe damage to the transmission.
WHAT TO DO IN EMERGENCIES 343
If the vehicle is to be towed more than 15 miles (25 km) the vehicle must be towed with the rear wheels raised and the front wheels on the ground. It may also be towed on a flatbed or with the front wheels raised and the rear wheels on a dolly.

ONBOARD DIAGNOSTIC SYSTEM (OBD II) Your vehicle is equipped with a sophisticated onboard diagnostic system called OBD II. This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions well within current government regulations. If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light.” It will also store diagnostic codes and other information to assist your service technician in making repairs. Al- though your vehicle will usually be driveable and not need towing, see your dealer for service as soon as possible.
CAUTION!
Prolonged driving with the “Malfunction Indicator Light” on could cause further damage to the emis- sion control system. It could also affect fuel economy and driveability. The vehicle must be serviced before any emissions tests can be performed. If the “Malfunction Indicator Light” is flashing, severe catalytic converter damage and power loss will soon occur. Immediate service is required.
EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system. Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and Maintenance) requirement, this check verifies the following: the MIL (Malfunction Indicator Lamp) is functioning and is not on when the engine is running, and that the OBD (On Board Diagnostic) system is ready for testing. Normally, the OBD system will be ready. The OBD system may not be ready if your vehicle was recently serviced, if you recently had a dead battery, or a battery replacement. If the OBD system should be determined not ready for the I/M test, your vehicle may fail the test.
MAINTAINING YOUR VEHICLE 351
Your vehicle has a simple ignition key actuated test which you can use prior to going to the test station. To check if your vehicle’s OBD system is ready, you must do the following: 1. Insert your ignition key into the ignition switch. 2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over. 4. As soon as you turn your key to the ON position, you will see your MIL symbol come on as part of a normal bulb check.
352 MAINTAINING YOUR VEHICLE
5. Approximately 15 seconds later, one of two things will happen:
a. The MIL light will blink for approximately 5 sec- onds and then remain on until the first engine crank or the key is turned off. This means that your vehicle’s OBD system is not ready and you should not proceed to the I/M station. b. The MIL light will remain fully illuminated until the first engine crank or the key is turned off. This means that your vehicle’s OBD system is ready and you can proceed to the I/M station.
If your OBD system is not ready, you should see your dealer or repair facility. If your vehicle was recently serviced or had a battery failure or replacement, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD system to update. A recheck with the above test routine may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD system is ready or not ready, if the MIL symbol is illuminated during normal vehicle operation, you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL symbol is on with the engine running.
DEALER SERVICE Your dealer has the qualified service personnel, special tools and equipment to perform all service operations in an expert manner. Service manuals are available which include detailed service information for your vehicle. Refer to these manuals before attempting any procedure yourself. NOTE: systems can result against you.

WARNING!
You can be badly injured working on or around a motor vehicle. Do only that service work for which you have the knowledge and the proper equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.
REPLACEMENT PARTS Use of genuine Mopar威 parts for normal/scheduled maintenance and repairs is highly recommended to in- sure the designed performance. Damage or failures caused by the use of non-Mopar parts for maintenance and repairs will not be covered by the manufacturer’s warranty.
MAINTAINING YOUR VEHICLE 353
MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides the maintenance items for which there are fixed maintenance intervals, there are other items that should operate satisfactorily without periodic maintenance. However, if a malfunction of these items does occur, it could adversely affect the engine or vehicle performance. These items should be inspected if a malfunction is observed or suspected. Engine Oil
Checking Oil Level To assure proper lubrication of your vehicle’s engine, the engine oil must be maintained at the correct level. The best time to check the engine oil level is about 5 minutes after a fully warmed up engine is shut off or before starting the engine after it has sat overnight.
354 MAINTAINING YOUR VEHICLE
Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings. Always maintain the oil level within the SAFE zone on the dipstick. Adding one quart of oil when the reading is at the bottom of the SAFE zone will result in a reading at the top of the safe zone on these engines.
Change Engine Oil
CAUTION!
Overfilling or underfilling the crankcase will cause oil aeration or loss of oil pressure. This could dam- age your engine.
Road conditions as well as your kind of driving affect the interval at which your oil should be changed. Check the following to determine if any apply to you: • Day or night temperatures are below 32°F (0°C). • Stop and go driving. • Extensive engine idling. • Driving in dusty conditions • Short trips of less than 10 miles (16.2 km)
speeds during hot weather, above 32°C (90°F)
• More than 50% of your driving is at sustained high • Trailer towing • Heavy Loading • Taxi, Police or delivery service (commercial service) • Off-road or desert operation • If equipped for and operating with E-85 (ethanol)
fuel.
If ANY of these apply to you then change your NOTE: engine oil every 3,000 miles (5 000 km) or 3 months, whichever comes first and follow schedule “B” of the ⬙Maintenance Schedules⬙ section of this manual. If none of these apply to you, then change your engine oil at every interval shown on schedule ⬙A⬙ of the ⬙Mainte- nance Schedules⬙ section of this manual.
MAINTAINING YOUR VEHICLE 355
Dusty Conditions Driving through dust-laden air increases the problems of keeping abrasive materials out of the engine. Under these conditions, special attention should be given to the engine air cleaner, the crankcase inlet air cleaner and the crankcase ventilation system. Make sure that these units are clean at all times. This will tend to reduce to a minimum the amount of abrasive material that may enter the engine. Engine Oil Selection For best performance and maximum protection under all types of operating conditions, the manufacture only recommends engine oils that are API certified and meet the requirements of DaimlerChrysler Material Standard MS-6395. Use Mopar or an equivalent oil meeting the specification MS-6395.
356 MAINTAINING YOUR VEHICLE
Engine Oil Identification (API) Symbol There is a symbol to aid you in selecting the proper engine oil.
This symbol means that the oil has been certified by the American Petroleum Institute (API). The manufacture only recommends API Certified engine oils that meet of DaimlerChrysler Material Stan- dard MS-6395. Use Mopar or an equivalent oil meeting the specifi-
requirements
the
cation MS-6395. Engine Oil Viscosity (SAE Grade) For 3.7L/4.7L engines SAE 5W-30 engine oil is recom- mended for all operating temperatures. For 5.7L en- gines SAE 5W-20 engine oil is recommended for all operating temperatures.These engine oils improve low
temperature starting and vehicle fuel economy. Refer to your engine oil filler cap for the recommended engine oil viscosity for your vehicle. For information on engine oil filler cap location, see the Engine Compartment illustration in this section. Lubricants which do not have both, the engine oil certi- fication mark and the correct SAE viscosity grade num- ber should not be used. Synthetic Engine Oils There are a number of engine oils being promoted as either synthetic or semi-synthetic. If you chose to use such a product, use only those oils that are API Certified and meet the SAE viscosity standard. Follow the service schedule that describes your driving type. Materials Added to Engine Oil The manufacture strongly recommends against the addi- tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and it’s performance may be impaired by supplemental ad- ditives. Disposing of Used Engine Oil And Oil Filters Care should be taken in disposing of used engine oil and oil filters from your vehicle. Used oil and oil filters, indiscriminately discarded, can present a problem to the environment. Contact your dealer, service station, or governmental agency for advice on how and where used oil and oil filters can be safely discarded in your area. Engine Oil Filter The engine oil filter should be replaced at every engine oil change. Engine Oil Filter Selection The manufacturer’s engines have a full-flow type oil filter. Use a filter of this type for replacement. The quality of replacement filters varies considerably. Only high
MAINTAINING YOUR VEHICLE 357
quality filters should be used to assure most efficient service. Mopar Engine Oil Filters are a high quality oil filter and are recommended. Drive Belts — Check Condition and Tensioner Belt tension is controlled by means of an automatic tensioner. No belt tension adjustments are required. However, belt and belt tensioner condition should be inspected at the specified intervals and replaced if re- quired. See your authorized dealer for service. At the mileage indicated in the maintenance schedule, all belts and tensioner should be checked for condition. Improper belt tension can cause belt slippage and failure. Belts should be inspected for evidence of cuts, cracks, glazing or frayed cords and replaced if there is indication of damage which could result in belt failure. Low gen- erator belt tension can cause battery failure.
358 MAINTAINING YOUR VEHICLE
Also check belt routing to make sure there is no interfer- ence between the belts and other engine components. Spark Plugs Spark plugs must fire properly to assure engine perfor- mance and emission control. New plugs should be in- stalled at the specified mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug, malfunctioning spark plugs can damage the cata- lytic converter. For proper type of replacement spark plugs, refer to the “Vehicle Emission Control Informa- tion” label in the engine compartment. Engine Air Cleaner Filter Under normal driving conditions, replace the air filter at the intervals shown on Schedule “A”. If, however, you drive the vehicle frequently under dusty or severe con- ditions, the filter element should be inspected periodi- cally and replaced if necessary at the intervals shown on Schedule “B”.
WARNING!
The air induction system (air cleaner, hoses, etc) can provide a measure of protection in the case of engine backfire. Do not remove the air induction system (air cleaner, hoses, etc) unless such removal is necessary for repair or maintenance. Make sure that no one is near the engine compartment before starting the vehicle with the air induction system (air cleaner, hoses, etc) removed. Failure to do so can result in serious personal injury.
Engine Fuel Filter A plugged fuel filter can cause stalling, limit the speed at which a vehicle can be driven or cause hard starting. Should an excessive amount of dirt accumulate in the fuel tank, frequent filter replacement may be necessary.
Catalytic Converter The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effectiveness of the catalyst as an emission control device. Under normal operating conditions, the catalytic con- verter will not require maintenance. However, it is im- portant to keep the engine properly tuned to assure proper catalyst operation and prevent possible catalyst damage.
MAINTAINING YOUR VEHICLE 359
CAUTION!
Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involv- ing engine misfire or other apparent loss of perfor- mance, have your vehicle serviced promptly. Contin- ued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and the vehicle.
NOTE: systems can result against you.

If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to Recommended Fluids, Lubricants, and Genuine Parts for correct fluid type.
if the seals on the ball
4 x 2 Models The ball joints and seals should be inspected whenever the vehicle is serviced for other reasons. The ball joints originally supplied with the vehicle are permanently lubricated at the factory and do not require service. However, joints are damaged, the joints should be replaced. Serviceable replacement ball joints are available. Front suspension ball joints should be replaced only by a qualified service technician using tools specially de- signed for this purpose. Damage to the joints and/or suspension components may result if improper replace- ment procedures are used. If seals are damaged the ball joints should be replaced to prevent leakage or contamination of the grease.
Steering Linkage — Inspection Whenever the vehicle is hoisted, all steering linkage joints should be inspected for evidence of damage. If seals are damaged, parts should be replaced to prevent leakage or contamination of the grease. Lubricate the steering linkage regularly according to the “Maintenance Schedule” in this manual. Half-shaft Constant Velocity Joints All four- wheel- drive 1500 models are equipped with four constant velocity joints. Periodic lubrication of these joints is not required. However, the joint boots should be inspected for external leakage or damage periodically. If external leakage or damage is evident, the joint boot and grease should be replaced immediately. Continued op- eration could result in failure of the joint due to water and dirt contamination of the grease. This would require complete replacement of the joint assembly. Refer to the Service Manual for the detailed replacement procedure.

Body Lubrication Locks and all body pivot points, including such items as seat tracks, doors, tailgate and hood hinges, should be lubricated periodically to assure quiet, easy operation and to protect against rust and wear. Prior to the appli- cation of any lubricant, the parts concerned should be wiped clean to remove dust and grit; after lubricating excess oil and grease should be removed. Particular attention should also be given to hood latching compo- nents to insure proper function. When performing other underhood services, the hood latch, release mechanism and safety catch should be cleaned and lubricated. The external lock cylinders should be lubricated twice a year, preferably in the fall and spring. Apply a small amount of a high quality lubricant such as Mopar威 Lock Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades The rubber edges of the wiper blades and the windshield should be cleaned periodically with a sponge or soft cloth and a mild nonabrasive cleaner. This will remove accu- mulations of salt or road film. Operation of the wipers on dry glass for long periods may cause deterioration of the wiper blades. Always use washer fluid when using the wipers to remove salt or dirt from a dry windshield. Avoid using the wiper blades to remove frost or ice from the windshield. Keep the blade rubber out of contact with petroleum products such as engine oil, gasoline, etc. Windshield Washers The fluid reservoir is located under the hood and should be checked for fluid level at regular intervals. Fill the reservoir with windshield washer solvent only (not ra- diator antifreeze).
To prevent freeze-up of your windshield washer system in cold weather, select a solution or mixture that meets or exceeds the temperature range of your climate. This rating information can be found on most washer fluid containers.
WARNING!
Commercially available windshield washer solvents are flammable. They could ignite and burn you. Care must be exercised when filling or working around the washer solution.
After the engine has warmed, operate the defroster for a few minutes to reduce the possibility of smearing or freezing the fluid on the cold windshield. Mopar All Weather Windshield Washer Solution, used with water as

Exhaust System The best protection against carbon monoxide entry into the vehicle body is a properly maintained engine exhaust system. Whenever a change is noticed in the sound of the exhaust system, when exhaust fumes can be detected inside the vehicle, or when the underside or rear of the vehicle is damaged, have a competent mechanic inspect the com- plete exhaust system and adjacent body areas for broken, damaged, deteriorated, or mispositioned parts. Open seams or loose connections could permit exhaust fumes to seep into the passenger compartment. In addition, inspect the exhaust system each time the vehicle is raised for lubrication or oil change. Replace as required.
368 MAINTAINING YOUR VEHICLE
WARNING!
Cooling System
Exhaust gases can injure or kill. They contain carbon monoxide (CO) which is colorless and odorless. Breathing it can make you unconscious and can eventually poison you. To avoid breathing CO, fol- low the preceding safety tips.
Exhaust System Rubber Isolator and Loop-Type Hanger — If Equipped Inspect surfaces whenever the vehicle is hoisted for rubber to metal separation or deep cracks. SLIGHT CRACKING DUE TO WEATHERING DOES NOT AD- VERSELY AFFECT PERFORMANCE. If, however, exces- sively deep localized cracks are present, or any part of the exhaust system abnormally contacts the underbody hard- ware, the isolator and/or hanger should be replaced.
Cooling System Maintenance At the intervals shown in the Maintenance Schedules Section of the manual, the system should be drained, flushed and filled. Inspection Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where applicable). If coolant is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh coolant as specified. Inspect the entire cooling system for leaks. Check the face of the radiator for any accumulation of bugs, leaves, or other foreign matter. If dirty, clean the radiator core with a garden hose. With the engine OFF, gently spray water from the back of the radiator core.For 3.7L, 4.7L, and 5.7L engines, check the coolant bottle hoses for condition and tightness of the connections at both the coolant bottle and radiator. Coolant Level ( 3.7L, 4.7L, 5.7L Engines) The coolant reserve system provides a quick visual method of determining that the coolant level is adequate. With the engine idling, and warmed to the normal operating temperature, the level of the coolant in the coolant bottle should be between the fluid level marks. Check the coolant level whenever the hood is raised. The radiator normally remains completely full, so there is no longer a need to remove the coolant pressure cap except for checking coolant freeze point or replacement with new antifreeze coolant.
MAINTAINING YOUR VEHICLE 369
WARNING!
Never add coolant to the radiator when the engine is overheated. Do not loosen or remove pressure cap to cool an overheated engine! The coolant is under pressure and severe scalding could result.
Drain, Flush And Refill At intervals shown on the Maintenance Schedules, the system should be drained, flushed and refilled. Refer to your dealer or consult a service manual for proper procedures. Adding Coolant When adding coolant, or refilling the system, a minimum solution of 50% recommended HOAT ethylene glycol engine coolant (antifreeze) and distilled water should be used. Use higher concentrations (not to exceed 70%) if temperatures below ⫺34°F (⫺37°C) are anticipated.
370 MAINTAINING YOUR VEHICLE
Use only high purity water such as distilled or deionized water when mixing the water/engine coolant solution. The use of lower quality water will reduce the amount of corrosion protection in the engine cooling system. It is the owner’s responsibility to maintain the NOTE: proper level of protection against freezing according to the temperatures occurring in the area where the vehicle is operated. NOTE: Mixing coolant types will decrease the life of the engine coolant and will require more frequent coolant changes. When additional coolant is needed to maintain the proper level, add the recommended concentration of antifreeze and water to the coolant bottle. Do not overfill.
NOTE: Failure to follow the antifreeze concentration and replacement recommendations, or failure to use antifreeze formulated to prevent corrosion of all cooling system metals, may result in radiator plugging, overheat- ing, or cooling system leaks such as in core hole plugs.
WARNING!
Never add coolant to the radiator when the engine is overheated. Do not loosen or remove pressure cap to cool an overheated engine. The coolant is under pressure and severe scalding could result.
Recommended Engine Coolant Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type.
CAUTION!
• Mixing of coolants other than specified engine coolant, may result in engine damage. If a non- HOAT coolant is introduced into the cooling sys- tem in an emergency, it should be replaced with the specified coolant as soon as possible. • Do not use plain water alone or alcohol base engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the radiator engine coolant and may plug the radiator. • This vehicle has not been designed for use with Propylene Glycol based coolants. Use of Propy- lene Glycol based coolants is not recommended.
MAINTAINING YOUR VEHICLE 371
Disposal Of Used Engine Coolant Used ethylene glycol based engine coolant is a regulated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. Do not store ethylene glycol-based engine coolant in open containers or allow it to remain in puddles on the ground. Prevent ingestion by animals and children. If ingested by a child, contact a physician immediately. Clean up any ground spills immediately. Coolant Pressure Cap The coolant pressure cap must be fully tightened to prevent the loss of coolant and to insure that the coolant will return to the radiator from the coolant bottle. The pressure cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.
372 MAINTAINING YOUR VEHICLE
WARNING!
The warning words “DO NOT OPEN HOT” on the radiator pressure cap are a safety precaution. Heat causes pressure to build up in the cooling system. To prevent scalding or injury, do not remove the pres- sure cap.
Hoses And Vacuum/Vapor Harnesses Inspect surfaces of hoses and nylon tubing for evidence of heat and mechanical damage. Hard or soft spots, brittle rubber, cracking, tears, cuts, abrasions, and exces- sive swelling indicate deterioration of the rubber. Pay particular attention to those hoses nearest to high heat sources such as the exhaust manifold. Inspect hose routing to be sure hoses do not come in contact with any heat source or moving component which may cause heat damage or mechanical wear.
Insure nylon tubing in these areas has not melted or collapsed. Inspect all hose connections such as clamps and cou- plings to make sure they are secure and no leaks are present. Components should be replaced immediately if there is any evidence of wear or damage that could cause failure. Brake System
Power Disc Brakes (front and rear) Disc brakes do not require periodic adjustment. Brake Master Cylinder The fluid level of the master cylinder should be checked when performing under the hood service, or immedi- ately if the brake system warning lamp indicates system failure.
The brake master cylinder has a translucent plastic reservoir. On the outboard side of the reservoir, there is a “MAX” dot and an “MIN” dot. The fluid level must be kept within these two dots. Do not add fluid above the MAX mark, because leakage may occur at the cap. With disc brakes the fluid level can be expected to fall as the brake linings wear. However, an unexpected drop in fluid level may be caused by a leak and a system check should be conducted. Refer to Recommended Fluids, Lubricants and Genuine Parts for the correct Fluid type.
WARNING!
Use of a brake fluid that may have a lower initial boiling point, or is unidentified as to specification, may result in sudden brake failure during hard prolonged braking. You could have an accident.
MAINTAINING YOUR VEHICLE 373
WARNING!
Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire.
Use only brake fluid that has been in a tightly closed container to avoid contamination from foreign matter or moisture.
CAUTION!
Do not allow a petroleum-base fluid to contaminate the brake fluid. Seal damage may result.
374 MAINTAINING YOUR VEHICLE
Brake Hoses Inspection should be performed whenever the brake system is serviced or at intervals specified. Inspect hy- draulic brake hoses for surface cracking, scuffing or worn spots. If there is any evidence of cracking, scuffing, or worn spots, the hose should be replaced immediately! Eventual deterioration of the hose can take place with possible burst failure. Clutch Hydraulic System
The clutch hydraulic system is a sealed maintenance-free system. In the event of leakage or other malfunction, the system must be replaced. Clutch Linkage If the clutch pedal linkage begins to squeak or grunt, the clutch pedal pivot bushings should be lubricated. Refer to Recommended Fluids, Lubricants and Genuine Parts for the correct lubricant type.
Rear Axle And 4x4 Front Driving Axle Fluid Level Refer to Recommended Fluids, Lubricants and Genuine Parts for the correct Fluid type. For normal service, periodic fluid level checks are not required. When the vehicle is serviced for other reasons the exterior surfaces of the axle assembly should be inspected. If gear oil leakage is suspected inspect the fluid level. This inspection should be made with the vehicle in a level position. The fluid level should be even with the bottom of the fill hole for the Manufacturer’s C205F HD Front Axles. The fluid level should be 5/8” (16 mm) below on 9 1/4” Manufacturer’s Rear Axles. For all 2500/3500 Model axles, the fluid level should be 1/4” ± 1/4” (6.4 mm ± 6.4 mm) below the fill hole on the 9.25” Front and 3/4”± 1/4” (19 mm ± 6.4 mm) on 10.5” Rear axles. The 11.5” Rear Axle level should be 1/4” ± 1/4” (6.4 mm ± 6.4 mm) below the fill hole.
Drain and Refill Vehicles operated in normal service do not have regularly scheduled oil changes. If fluid has become contaminated with water or to provide the correct viscosity grade, drain and refill. Lubricant Selection Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. NOTE: The presence of water in the gear lubricant will result in corrosion and possible failure of differential components. Operation of the vehicle in water, as may be encountered in some off-highway types of service, will require draining and refilling the axle to avoid damage.

Lubricant Selection Getrag G56 (6-Speed Manual Transmission — If Equipped) This transmission is filled with manual transmission fluid at the factory. This fluid does not require periodic changing. If it is necessary to add or change fluid in this transmission refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. This is the only lubricant recommended for use in the Getrag G56 trans- mission. Automatic Transmission
Fluid Level Check The fluid level should be checked when the engine is fully warmed up and the fluid in the transmission is at normal operating temperature. Operation of the trans- mission with an improper fluid level will greatly reduce the life of the transmission and of the fluid. Check the fluid level whenever the vehicle is serviced.
MAINTAINING YOUR VEHICLE 377
Fluid Level Check – 45RFE/545RFE Check the fluid level while the transmission is at normal operating temperature 82°C (180°F). This occurs after at least 15 miles (25 km) of driving. At normal operating temperature the fluid cannot be held comfortably be- tween the fingertips. To check the automatic transmission fluid level properly, the following procedure must be used: 1. Operate the engine at idle speed and normal operating temperature. 2. The vehicle must be on level ground. 3. Fully apply the parking brake and press the brake pedal. 4. Place the gear selector momentarily in each gear position ending with the lever in P (Park).

5. Remove the dipstick, wipe it clean and reinsert it until seated. 6. Remove the dipstick again and note the fluid level on both sides. The fluid level should be between the “HOT” (upper) reference holes on the dipstick at normal operat- ing temperature. Verify that solid coating of oil is seen on both sides of the dipstick. If the fluid is low, add as required into the dipstick tube. Do not overfill. After adding any quantity of oil through the oil fill tube, wait a minimum of two (2) minutes for the oil to fully drain into the transmission before rechecking the fluid level. If it is necessary to check the transmission below NOTE: the operating temperature, the fluid level should be between the two “COLD” (lower) holes on the dipstick with the fluid at approximately 70°F (21°C) (room tem- perature). If the fluid level is correctly established at it should be between the “HOT” room temperature,
(upper) reference holes when the transmission reaches 180°F (82°C). Remember it is best to check the level at the normal operating temperature.
CAUTION!
Be aware that if the fluid temperature is below 50°F (10°C) it may not register on the dipstick. Do not add fluid until the temperature is elevated enough to produce an accurate reading.
7. Check for leaks. Release parking brake. To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is properly reseated. It is normal for the dipstick cap to spring back slightly from its fully seated position, as long as its seal remains engaged in the dipstick tube.
Selection Of Lubricant Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. It is important that the transmission fluid be maintained at the prescribed level using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac- turers recommended fluid may cause deterioration in transmission shift quality and/or torque converter shudder. Using a transmission fluid other than the manufacturers recommended fluid will result in more frequent fluid and filter changes. Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type.

Automatic Transmission Fluid and Filter Change It is important that proper lubricant is used in the transmission. Refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type. The fluid and filter(s) should be changed as specified in the Maintenance Schedule (Section 8). NOTE: reason, the fluid and filter(s) should be changed. Special Additives The manufacturer strongly recommends against the ad- dition of any additives to the transmission. Exception to this policy is the use of special dyes to aid in detecting fluid leaks. The use of transmission sealers should be avoided, since they may adversely affect seals.

Front Wheel Bearings Front wheel bearings for all Dodge Ram Trucks are sealed-for-life. They do not require greasing or seal replacement. these bearings will “purge” excess grease and the bearing will look slightly wet. This is normal. Periodic inspection for excess play is recommended. Rear Wheel Bearings — Manufacturer’s Axles These bearings are normally considered permanently lubricated. Cleaning and repacking is required only when axle shafts are removed or in case of extreme water or dust contamination. Selection of Lubricating Grease The National Lubricating Grease Institute (NLGI) has developed a symbol (Certification Mark) to aid the vehicle owner in the proper selection of grease for the lubrication of wheel bearings and chassis components.
This symbol (an example is shown below) is located on the grease container and identifies the application and quality of the grease.

Appearance Care and Protection from Corrosion
Protection of Body and Paint from Corrosion Vehicle body care requirements vary according to geo- graphic locations and usage. Chemicals that make roads passable in snow and ice, and those that are sprayed on trees and road surfaces during other seasons, are highly corrosive to the metal in your vehicle. Outside parking, which exposes your vehicle to airborne contaminants, road surfaces on which the vehicle is operated, extreme hot or cold weather and other extreme conditions will have an adverse effect on paint, metal trim, and under- body protection. The following maintenance recommendations will enable you to obtain maximum benefit from the corrosion resistance built into your vehicle. What Causes Corrosion? Corrosion is the result of deterioration or removal of paint and protective coatings from your vehicle.
MAINTAINING YOUR VEHICLE 385
The most common causes are: • Road salt, dirt and moisture accumulation. • Stone and gravel impact. • Insects, tree sap and tar. • Salt in the air near seacoast localities. • Atmospheric fallout/industrial pollutants. Washing • Wash your vehicle regularly. Always wash your ve- hicle in the shade using a mild car wash soap, and rinse the panels completely with clear water.

Do not attempt to fold the 7 x 10 inch trailer towing mirrors forward. The 7 x 10 inch trailer towing mirrors are not designed to be folded forward and doing so will damage the mirrors and/or vehicle. • If insects, tar or other similar deposits have accumu- • Use Mopar威 auto polish to remove road film and stains and to polish your vehicle. Take care never to scratch the paint. • Avoid using abrasive compounds and power buffing that may diminish the gloss or thin out the paint finish.
Do not use abrasive or strong cleaning materials such as steel wool or scouring powder, which will scratch metal and painted surfaces.
Special Care • If you drive on salted or dusty roads or if you drive near the ocean, hose off the undercarriage at least once a month. • It is important that the drain holes in the lower edges of the doors, rocker panels and tailgate be kept clear and open. • If you detect any stone chips or scratches in the paint, touch them up immediately. The cost of such repairs is considered the responsibility of the owner.
• If your vehicle is damaged due to an accident or similar cause which destroys the paint and protective coating have your vehicle repaired as soon as possible. The cost of such repairs is considered the responsibil- ity of the owner. • All wheels and wheel trim, especially aluminum and chrome plated wheels should be cleaned regularly with mild soap and water to prevent corrosion. To remove heavy soil, select a nonabrasive, non-acidic cleaner. Do not use scouring pads, steel wool, a bristle brush or metal polishes. Only Mopar cleaners are recommended. Do not use oven cleaner. Avoid auto- matic car washes that use acidic solutions or harsh brushes that may damage the wheels’ protective fin- ish. • If you carry special cargo such as chemicals, fertilizers, de-icer salt, etc., be sure that such materials are well packaged and sealed.

and Mopar威 Total Clean. Care should be taken to avoid soaking your leather upholstery with any liquid. Please do not use polishes, oils, cleaning fluids, solvents, deter- gents, or ammonia based cleaners to clean your leather upholstery. Application of a leather conditioner is not required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes. Many are potentially flammable, and if used in closed areas they may cause respiratory harm.
Glass Surfaces All glass surfaces should be cleaned on a regular basis with any commercial household-type glass cleaner. Never use an abrasive type cleaner. Use caution when cleaning inside rear windows equipped with electric defrosters or windshields equipped with a windshield wiper de-icer. Do not use scrapers or other sharp instru- ments which may scratch the elements. When cleaning the rear view mirror, spray cleaner on the towel or rag that you are using. Do not spray cleaner directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses The lenses in front of the instruments in this vehicle are molded in clear plastic. When cleaning the lenses, care must be taken to avoid scratching the plastic. 1. Clean with a wet soft rag. A mild soap solution may be used, but do not use high alcohol content or abrasive cleaners. If soap is used, wipe clean with a clean damp rag. 2. Dry with a soft tissue. Seat Belt Maintenance Do not bleach, dye or clean the belts with chemical solvents or abrasive cleaners. This will weaken the fabric. Sun damage will also weaken the fabric. If the belts need cleaning, use a mild soap solution or lukewarm water. Do not remove the belts from the car to wash them.
