Dodge Durango Models

STARTING AND OPERATING 307

WARNING!

Snowplows, winches, and other aftermarket equip- ment should not be added to the front end or your vehicle. The airbag crash sensors may be affected by the change in the front end structure. The airbags could deploy unexpectedly or could fail to deploy during a collision resulting in serious injury or death.

NOTE: Do not use Dodge Durango Models for snow- plow applications.

CAUTION!

Using this vehicle for snowplow applications can cause damage to the vehicle.

308 STARTING AND OPERATING

WARNING!

Recreational Towing 4WD Models

CAUTION!

Vehicles equipped with an NV 144 Transfer Case (which has no neutral position) may NOT be used for recreational towing.

Attaching a snowplow to this vehicle could ad- versely affect performance of the airbag system in an accident. Do not expect that the airbag will perform as described earlier in this manual

RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)

Recreational Towing 2WD Models Recreational towing of 2WD models is not allowable. Towing the vehicle with the transmission in Neutral can cause severe transmission damage. Removal of the drive- shaft for towing is not recommended since this allows transmission fluid to leak out.

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!

Internal damage to the transfer case will occur if a front or rear wheel lift is used when recreational towing.

STARTING AND OPERATING 309

NOTE: The NV 244 Generation II transfer case must be shifted into Neutral (N) for recreational towing. The Neutral (N) selection button is located on the lower left hand corner of the 4WD Control Switch. Shifts into and out of transfer case Neutral (N) can take place with the selector switch in any mode position. Shifting into Neutral (N) Use the following procedure to prepare your vehicle for recreational towing.

CAUTION!

It is necessary to follow these steps to be certain that the transfer case is fully in Neutral (N) before recreational towing to prevent damage to internal parts.

1. Bring vehicle to a complete stop.

310 STARTING AND OPERATING

312 STARTING AND OPERATING

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 are not met prior to depress- ing the Neutral (N) button or are no longer met during the 1 second time, then all of the position indicator lights will flash continuously until all requirements 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. NOTE: Flashing neutral (N) position indicator light indicates that shift requirements have not been met.

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 damage internal parts.

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.

STARTING AND OPERATING 313

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.

CHANGING A FLAT TIRE

Jack Location In the Durango, the scissor jack and tire changing tools are stowed under the second row seat. The jack is secured in place with a winged stud and a fixed stud. It is very important to secure the jack tightly in place by engaging the slot in the base to the fixed stud under the middle seat. The winged stud inserts through the eyelet in the end of the jack’s worm screw.

318 WHAT TO DO IN EMERGENCIES

WARNING!

The jack is designed as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes, unless suitable supports are placed under the vehicle as a safety measure. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas.

Removing The Spare Tire The spare tire on the Dodge Durango is located under- neath the vehicle in the rear.

WHAT TO DO IN EMERGENCIES 319

Remove the spare tire before attempting to jack the truck. 1. Remove the rubber plug from the floor in the cargo area.

2. Engage the jack wrench extension to the spare tire winch through the hole in the floor. 3. Turn the wrench counterclockwise to lower the spare tire. Continue to turn the wrench until the spare tire can be pulled out from under the vehicle.

320 WHAT TO DO IN EMERGENCIES

It is recommended that you stow the flat or spare to avoid tangling the loose cable.

Tire Changing Procedure

CAUTION!

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.

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 scissor 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.

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). 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. • Turn on the Hazard Warning Flasher.

WHAT TO DO IN EMERGENCIES 321

• Block both the front and rear of the wheel diagonally oppo- site the jacking position. For example, front wheel is being changed, block the left rear wheel. • Passengers should not remain in the vehicle when the

To Stow The Flat Or Spare Turn the wheel so that the valve stem is down. Slide the wheel retainer through the center of the wheel and position it properly across the wheel opening. For convenience in checking the spare tire inflation, stow with the valve stem toward the rear of the vehicle. 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 2 times. It cannot be overtightened. Push against the tire several times to be sure it is firmly in place.

WHAT TO DO IN EMERGENCIES 325

JUMP STARTING

WARNING!

• Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or cloth- ing. 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 the con- taminated area immediately 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 with an output that exceeds 12 volts.

326 WHAT TO DO IN EMERGENCIES

Check the Battery Test Indicator (if equipped). If a light 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. Wear eye protection and 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, place the automatic transmission in PARK and turn the ignition OFF on both vehicles. 3. Turn OFF heater, radio and all unnecessary electrical 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.

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!

WARNING!

WHAT TO DO IN EMERGENCIES 327

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 below 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.

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.

EMERGENCY TOW HOOKS — IF EQUIPPED Your vehicle may be equipped with emergency tow hooks.

328 WHAT TO DO IN EMERGENCIES

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.

CAUTION!

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.

TOWING A DISABLED VEHICLE Proper towing or lifting equipment is required to prevent damage to your vehicle. Use of safety chains is recom- mended. Attach towing device to main structural mem- bers of the vehicle — not to bumpers or associated brackets. State and local laws applying to vehicles under tow must be observed.

Four-Wheel Drive Vehicles The manufacturer recommends towing with all wheels OFF the ground. Acceptable methods are to tow the vehicle on a flatbed or with one end of the vehicle raised and the opposite end on a towing dolly. Two-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. The speed must not exceed 30
mph (50 km/h) and the distance must not exceed 15
miles (25 km).

WHAT TO DO IN EMERGENCIES 329

If the vehicle is to be towed more than 15 miles (25 km ) or faster than 30 mph, it must be towed on a flatbed, or with the rear wheels raised and the front wheels on the ground, or with the front end raised and the rear wheels on a towing dolly. NOTE: Towing the vehicle, with the rear wheels on the ground, at more than 30 mph (50 km/h) or for more than 15 miles (25 km ) can cause severe transmission damage.

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 drivable and not need towing, see your dealer for service as soon as possible.

MAINTAINING YOUR VEHICLE 337

CAUTION!

• Prolonged driving with the “Malfunction Indica- tor Light” on could cause further damage to the emission control system. It could also affect fuel economy and driveability. The vehicle must be serviced before any emissions tests can be per- formed. • If the “Malfunction Indicator Light” is flashing while the engine is running, severe catalytic con- verter damage and power loss will soon occur. Immediate service is required.

Loose Fuel Filler Cap Message After fuel is added, the vehicle diagnostic system can determine if the fuel filler cap is loose, improperly installed, or damaged. A loose fuel filler cap message will be displayed in the instrument cluster. Tighten the gas

338 MAINTAINING YOUR VEHICLE

cap until a ⬙clicking⬙ sound is heard. This is an indication that the gas cap is properly tightened. Press the odometer reset button to turn the message off. If the problem persists, the message will appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the Malfunction Indicator Light (MIL). Resolving the problem will turn the MIL light off.

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 is determined not ready for the I/M test, your vehicle may fail the test. 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. If you crank or start the engine, you will have to start this test over.

3. 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. 4. 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

MAINTAINING YOUR VEHICLE 339

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.

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威 parts for maintenance and repairs will not be covered by the manufacturer’s warranty.

340 MAINTAINING YOUR VEHICLE

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.

Intentional tampering with emissions control in civil penalties being assessed

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.

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 Engine 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.

1. Position the vehicle on a level surface. 2. Turn Off the engine and allow approximately 5 min- utes for the oil to settle to the bottom of the crankcase. 3. Remove the engine oil level indicator (dipstick). 4. Wipe the engine oil level indicator (dipstick) clean. 5. Install the engine oil level indicator (dipstick) and make sure it is seated in the tube. 6. Remove the engine oil level indicator (dipstick), keep- ing the handle above the tip, and read the oil level on the engine oil level indicator (dipstick). 7. Add oil only if the level is below the “SAFE” range (at or below the “ADD” mark) on the engine oil level indicator (dipstick). Adding one quart of oil when the reading is at the ADD mark will result in a reading at the top of the SAFE range.

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. 4x4 Models, If Used Primarily For Off-Road Operation Every 50 hours of use. 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 and the crankcase inlet air cleaner. The crankcase ventilation system should also be checked

periodically. Make sure that these units are always clean. 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. Engine Oil Identification (API) Symbol There is a symbol to aid you in selecting the proper engine oil.

MAINTAINING YOUR VEHICLE 343

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 the 5.7L engine SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. Your engine oil filler cap also shows the recommended engine oil viscosity for your vehicle.

344 MAINTAINING 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 meet the Ameri- can Petroleum Institute (API) and SAE viscosity stan- dard. Follow the service schedule that describes your driving type. Materials Added to Engine Oils 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 quality filters should be used to assure most efficient service. Mopar威 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 generator belt tension can cause battery failure. Also check belt routing to make sure there is no interference between the belts and other engine components.

MAINTAINING YOUR VEHICLE 345

Spark Plugs Spark plugs must fire properly to assure proper engine performance and emission control. The plugs installed in your vehicle should operate satisfactorily in normal service for the mileage indicated in the Maintenance Chart. New plugs should be installed at this mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Check the Vehicle Emissions Control Information label for the proper type of spark plug for your vehicle.

CAUTION!

When replacing plugs, do not overtighten. You could damage them and cause them to leak.

346 MAINTAINING YOUR VEHICLE

Ignition Cables Replace the ignition cables (5.7L engines only) at the mileage interval shown in the maintenance charts. 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 cleaner can provide a measure of protection in the case of engine backfire. Do not remove the air cleaner 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 cleaner 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 347

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.

WARNING!

A hot exhaust system can start a fire if you park over materials that can burn. Such materials might be grass or leaves coming into contact with your ex- haust system. Do not park or operate your vehicle in areas where your exhaust system can contact any- thing that can burn.

In unusual situations involving grossly malfunctioning engine operation, a scorching odor may indicate severe and abnormal catalyst overheating. If this occurs, the vehicle should be stopped, the engine shut off and the vehicle allowed to cool. Thereafter, service, including a tune-up to manufacturer’s specifications, should be ob- tained immediately.

To minimize the possibility of catalyst damage: • Do not shut off the engine or interrupt the ignition when the transmission is in gear and the vehicle is in motion. • Do not try to start engine by pushing or towing the • Do not idle the engine with any spark plug wires disconnected or removed, such as when diagnostic testing, or for prolonged periods during very rough idling or malfunctioning operating conditions.

Battery posts, terminals, and related accessories con- tain lead and lead compounds. Always wash hands after handling the battery.

To determine the battery charge, check the battery test indicator (if equipped) on top of the battery. Refer to the illustration.

It is essential when replacing the cables on the battery that the positive cable is attached to the positive post and the negative cable is attached to the negative post. Battery posts are marked (+) positive and negative (-) and identified on the battery case. Also, if a “fast charger” is used while battery is in the vehicle, disconnect both vehicle battery cables be- fore connecting the charger to battery. Do not use a “fast charger” to provide starting voltage.

Air Conditioner Maintenance For best possible performance, your air conditioner should be checked and serviced by an Authorized Dealer at the start of each warm season. This service should include cleaning of the condenser fins and a performance test. Drive belt tension should also be checked at this time.

350 MAINTAINING YOUR VEHICLE

WARNING!

• Use only refrigerants and compressor lubricants approved by the manufacturer for your air condi- tioning system. Some unapproved refrigerants are flammable and can explode, injuring you. Other unapproved refrigerants or lubricants can cause the system to fail, requiring costly repairs. Refer to Section 3 of the Warranty Information book for further warranty information. • The air conditioning system contains refrigerant under high pressure. To avoid risk of personal injury or damage to the system, adding refrigerant or any repair requiring lines to be disconnected should be done by an experienced repairman.

Refrigerant Recovery and Recycling R-134a Air Conditioning Refrigerant is a hydrofluorocar- bon (HFC) that is endorsed by the Environmental Pro- tection Agency and is an ozone-saving product. How- ever, the manufacturer recommends that air conditioning service be performed by dealers or other service facilities using recovery and recycling equipment. Power Steering — Fluid Check Checking the power steering fluid level at a defined service interval is not required. The fluid should only be checked if a leak is suspected, abnormal noises are apparent, and/or the system is not functioning as antici- pated. Coordinate inspection efforts through a certified DaimlerChrysler Dealership.⬙

WARNING!

Fluid level should be checked on a level surface and with the engine off to prevent injury from moving parts and to insure accurate fluid level reading. Do not overfill. Use only manufacturers recommended power steering fluid.

If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to Fluids, Lubricants, and Genuine Parts for correct fluid type. Front Suspension Ball Joints The ball joints and seals should be inspected whenever the vehicle is serviced for other reasons. Damaged seals should be replaced to prevent leakage or contamination of the grease.

MAINTAINING YOUR VEHICLE 351

Drive Shaft Constant Velocity Joints All four wheel drive models are equipped with four constant velocity joints. Periodic lubrication of these joints is not required. However, the joint boot 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,liftgate 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

352 MAINTAINING YOUR VEHICLE

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 should be checked for fluid level at regular intervals. When freezing weather is anticipated, flush out the water in the reservoir by operating the system. Fill the reservoir with windshield washer anti- freeze (not radiator antifreeze), and operate the system for a few seconds to flush out the residual water. 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威 All Weather Windshield Washer Solution used with water as directed on the container, aids cleaning action, reduces freezing point to avoid line clogging, and is not harmful to paint or trim.

MAINTAINING YOUR VEHICLE 353

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.

354 MAINTAINING YOUR VEHICLE

WARNING!

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.

Cooling System

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. Check face of radiator for any accumulation of bugs, leaves, etc. If dirty, clean the radiator core by gently spraying water from a garden hose at the back of the core.

Check the coolant bottle tubing for condition and tight- ness of connection at coolant bottle and radiator. Inspect the entire system for leaks. With the engine at normal operating temperature (but not running), check the coolant pressure cap for proper vacuum sealing by draining a small amount of coolant from the radiator drain cock. If the cap is sealing prop- erly, the coolant will begin to drain from the coolant bottle. Do not remove the pressure cap when the cooling system is hot.

WARNING!

You or others can be badly burned by hot coolant or steam from your radiator. If you see or hear steam coming from under the hood don’t open the hood until the radiator has had time to cool. If you open the hood and see steam or hot coolant escaping from the radiator, don’t touch anything. Get away quickly. Never try to open a pressure cap when the radiator is hot.

Cooling System Maintenance At the intervals shown in the Maintenance Schedules section of this manual, the system should be drained, flushed and refilled. See your authorized dealer for proper cooling system maintenance.

MAINTAINING YOUR VEHICLE 355

Cooling System — Drain, Flush And Refill If the solution is dirty and contains a considerable amount of sediment, it should be cleaned and flushed. See your authorized dealer for proper draining, flushing and refilling of your vehicle’s cooling system. 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.

356 MAINTAINING YOUR VEHICLE

Recommended Engine Coolant This vehicle has been factory filled with an Ethylene Glycol based engine coolant with long life corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology). Follow the “Maintenance Schedule” for the recommended coolant change intervals. Refer to Fluids, Lubricants and Genuine Parts for correct fluid type.

CAUTION!

• Mixing of coolants other than specified engine coolant, may result in engine damage, and de- crease corrosion protection. If a non-HOAT cool- ant is introduced into the cooling system in an emergency, it should be replaced with the speci- fied 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.

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. 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. Please note that it is the owner’s responsibility to main- tain the proper level of protection against freezing ac- cording 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.

MAINTAINING YOUR VEHICLE 357

WARNING!

Never add coolant to the radiator when the engine is overheated. Do not loosen or remove pressure cap to cool overheated engine. The coolant is under pres- sure and severe scalding could result.

Coolant Pressure Cap The coolant pressure cap must be fully tightened to prevent loss of coolant, and to insure that coolant will return to the radiator from the coolant recovery bottle. The pressure cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.

358 MAINTAINING YOUR VEHICLE

WARNING!

The warning words “DO NOT OPEN HOT” on the coolant 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 when the system is hot or under pressure.

Coolant Level The coolant bottle system provides a quick visual method for determining that the coolant level is adequate. With the engine idling, and warmed to normal operating temperature, remove the cap from the bottle, remove the dipstick and wipe the excess coolant from it. Reinsert the dipstick and remove. Observe the dipstick checking the holes along the stem for coolant. Check the coolant level whenever the hood is raised.

The radiator normally remains completely full, so there is no need to remove the pressure cap except checking coolant freeze point or replacement with new antifreeze coolant. Your service attendant should be advised of this. When additional coolant is needed to maintain the proper level, it should be added to the coolant bottle. Do not overfill. Points To Remember A. Do not overfill the coolant bottle. B. Check coolant freeze point in the radiator and in the coolant bottle. If antifreeze needs to be added, contents of coolant bottle also must be protected against freezing. C. If frequent coolant additions are required, or if the level in the coolant bottle does not drop when the engine cools, the cooling system should be pressure tested for leaks.

D. Maintain coolant concentration at 50% HOAT ethyl- ene glycol engine coolant (minimum) and distilled water for proper corrosion protection of your engine. E. Make sure that the radiator and coolant bottle over- flow hoses are not kinked or obstructed. F. Keep the front of the radiator clean. If your vehicle is equipped with air conditioning, keep the front of the condenser clean also. G. The thermostat should not be changed for summer or winter operation. If replacement is ever necessary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory cooling performance. Emission Related Components

Fuel System Hoses And Vapor/Vacuum Harnesses When the vehicle is serviced for scheduled maintenance, inspect surface of hoses and nylon tubing for evidence of heat and mechanical damage. Hard and brittle rubber,

MAINTAINING YOUR VEHICLE 359

cracking, checking, tears, cuts, abrasions, and excessive swelling suggest deterioration of the rubber. Particular attention should be given to examining hose surfaces nearest to high heat sources, such as the exhaust mani- fold. Insure nylon tubing in these areas has not melted or collapsed. Inspect all hose clamps and couplings to make sure they are secure and no leaks are present. NOTE: Fluids such as oil, power steering fluid, and brake fluid are used during assembly plant operations to ease the assembly of hoses to couplings. Therefore, oil wetness at the hose-coupling area is not necessarily an indication of leakage. Actual dripping of hot fluid when systems are under pressure (during vehicle operation), should be noted before hose is replaced based on leakage.

360 MAINTAINING YOUR VEHICLE

You are urged to use only the manufacturer’s specified hoses and clamps, or their equivalent in material and specification, in any fuel system servicing. It is manda- tory to replace all clamps that have been loosened or removed during service. Care should be taken in install- ing new clamps to insure they are properly torqued. Positive Crankcase Ventilation (PCV) Valve Proper operation of the crankcase ventilation system requires that the PCV valve be free of sticking or plug- ging because of deposits. Deposits can accumulate in the PCV valve and passage with increasing mileage. Have the PCV valve, hoses, and passages checked for proper operation at the valve is plugged or sticking, replace with a new valve – Do not attempt to clean the PCV valve!

Brake System

Power Disc Brakes (Front and Rear) Disc brakes do not require adjustment; however, several hard stops during the break-in period are recommended to seat the linings and wear off any foreign material. Brake Master Cylinders The fluid level in the master cylinders should be checked whenever the vehicle is serviced, or immediately if the brake system warning light is on. If necessary, add fluid to bring level to the full mark on the side of the reservoir of the brake master cylinder. Be sure to clean the top of the master cylinder area before removing the cap. With disc brakes, fluid level can be expected to fall as the brake pads wear. Brake fluid level should be checked when pads are replaced. If the brake fluid level is abnormally low, check system for leaks. Refer to Fluids, Lubricants and Genuine Parts for correct fluid type.

WARNING!

CAUTION!

MAINTAINING YOUR VEHICLE 361

Use of brake fluid that may have a lower initial boiling point, or is unidentified, as to specifications may result in sudden brake failure during hard prolonged braking. You could have an accident.

WARNING!

Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching on fire.

Use only brake fluid that has been in a tightly closed container to avoid contamination from foreign matter or moisture.

Do not allow a petroleum-base fluid to contaminate the brake fluid. Seal damage may result.

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.

362 MAINTAINING YOUR VEHICLE

WARNING!

Worn brake hoses can burst and cause brake failure. You could have an accident. If you see any sign of cracking, scuffing, or worn spots, have the brake hoses replaced immediately.

Automatic Transmission

Fluid Level Check Check the fluid level while the transmission is at normal operating temperature 180°F (82°C). This occurs after at least 15 miles (24 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 temperature). If the fluid level is correctly established at room temperature, it should be between the “HOT” (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.

MAINTAINING YOUR VEHICLE 363

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. Automatic Transmission Fluid And Filter Change It is important that proper lubricant is used in the transmission. Refer to 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.

364 MAINTAINING YOUR VEHICLE

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 Fluids, Lubricants and Genuine Parts for correct fluid type.

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.

Transfer Case Inspect the transfer case for fluid leaks. If a fluid leak is evident the transfer case fluid level may be low. Have the transfer case serviced immediately.

CAUTION!

Damage may result from operation of the vehicle with low transfer case fluid.

The transfer case fluid should be drained and refilled at the intervals specified. Lubricant Selection Refer to Fluids, Lubricants and Genuine Parts for correct fluid type.

Axles Refer to Fluids, Lubricants and Genuine Parts for correct fluid type. The manufacturer does not recommend regularly sched- uled oil changes for axles in vehicles whose operation is classified as normal truck service. 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. Rear Axle Rear Axle fluid levels should be 7/8⬙ (22 mm) below the fill hole for 8 1/4⬙ axles, and 1 1/4⬙ (31 mm) below the fill hole for 9 1/4⬙ axles.

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.

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. • 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.

lated on your vehicle, wash it as soon as possible.

MAINTAINING YOUR VEHICLE 367

• Avoid using abrasive compounds and power buffing that may diminish the gloss or thin out the paint finish.

CAUTION!

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 liftgate be kept clear and open.

368 MAINTAINING YOUR VEHICLE

• 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威 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. • If a lot of driving is done on gravel roads, consider • Use Mopar威 touch up paint on scratches as soon as possible.

Stubborn soils can be removed easily with a soft cloth 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.

370 MAINTAINING YOUR VEHICLE

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. Replace the belts if they appear frayed or worn or if the buckles do not work properly.

POWER DISTRIBUTION CENTER (FUSE/RELAY) Your vehicle is equipped with two electrical power distribution centers located next to each other in the left side of the engine compartment. The power distribution centers house new plug-in “Maxi” fuses which replace all the in-line fusible links previously used. The power distribution centers also contain “Mini”fuses and plug-in “ISO” relays. A label inside the latching cover of the Power Distribution Cen- ters identifies each component for ease of replacement, if necessary. These fuses and relays can be obtained from your dealer.

FUSE BLOCK

CAUTION!

When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it suggests a problem in the circuit that must be corrected.

If you are leaving your vehicle dormant for NOTE: longer than 21 days you may want to take steps to protect your battery. You may do this by disconnecting the battery or by disconnecting the two ignition-off draw (I.O.D.) fuses located in the Auxiliary Power Distribution Center (PDC) located in the engine compartment. The I.O.D. cavities include a snap-in retainer that allows the

MAINTAINING YOUR VEHICLE 371

fuse to be disconnected, without removing it from the fuse block. Pressing the I.O.D. fuse back into the cavity reconnects it. Interior Fuses The fuse block contains blade-type mini-fuses, relays, and circuit breakers for high-current circuits. It is located in the left kick panel. It is accessible through a snap-in cover.
