2007 Dodge Durango Owners Manual

Fuel Filler Cap (Gas Cap)

The gas cap is behind the fuel filler door. If the gas cap is lost or damaged, be sure the replacement cap is for use with this vehicle. NOTE: To avoid contact between fuel cap and paint, hang tether strap over hook provided on inner fuel door.

CAUTION!

Damage to the fuel system or emission control system could result from using an improper fuel tank filler tube cap (gas cap). A poorly fitting cap could let impurities into the fuel system.

CAUTION!

A poorly fitting gas cap may cause the Malfunction Indicator Light to turn on.

CAUTION!

To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.

NOTE: When the fuel nozzle “clicks” or shuts off, the fuel tank is full.

STARTING AND OPERATING 315

WARNING!

• Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank filled. • Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and will cause the malfunction indi- cator light to turn on.

NOTE: Tighten the gas cap about 1/4 turn until you hear one click. This is an indication that cap is properly tightened. If the gas cap is not tighten properly, the Malfunction Indicator Light will come on. Be sure the gas cap is tightened every time the vehicle is refueled.

316 STARTING AND OPERATING

WARNING!

A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling.

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 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.

CAUTION!

Damage to the fuel system or emission control system could result from using an improper fuel tank filler cap (gas cap). A poorly fitting cap could let impurities into the fuel system.

WARNING!

• Never add fuel when the engine is running. • Never have any smoking materials lit in or near the vehicle when the fuel cap is removed or the tank filled.

FLEXIBLE FUEL

E-85 General Information The information in this section is for Flexible Fuel ve- hicles only. These vehicles can be identified by the unique fuel filler door label that states Ethanol (E-85) or Un- leaded Gasoline Only. This section only covers those subjects that are unique to these vehicles. Please refer to the other sections of this manual for information on features that are common between Flexible Fuel and gasoline only powered vehicles.

STARTING AND OPERATING 317

CAUTION!

Only vehicles with the E-85 fuel filler door label can operate on E-85.

ETHANOL FUEL (E-85) E-85 is a mixture of approximately 85% fuel ethanol and 15% unleaded gasoline.

WARNING!

Ethanol vapors are extremely flammable and could cause serious personal injury. Never have any smok- ing materials lit in or near the vehicle when remov- ing the fuel filler tube cap (gas cap) or filling the tank. Do not use E-85 as a cleaning agent and never use it near an open flame.

318 STARTING AND OPERATING

Fuel Requirements Your vehicle will operate on both unleaded gasoline with an octane rating of 87, or E-85 fuel, or any mixture of these two. For best results, a refueling pattern that alternates be- tween E-85 and unleaded gasoline should be avoided. When you do switch fuels, it is recommended that • you do not switch when the fuel gauge indicates less • you do not add less than 5 gallons when refueling • you operate the vehicle immediately after refueling for

than 1/4 full

a period of at least 5 minutes

Observing these precautions will avoid possible hard starting and/or significant deterioration in drivability during warm up.

NOTE: When the ambient temperature is above 90°F, you may experience hard starting and rough idle follow- ing start up even if the above recommendations are followed. Selection Of Engine Oil For Flexible Fuel Vehicles (E-85) and Gasoline Vehicles Whether operating the vehicle on an E-85 ethanol fuel or unleaded gasoline the engine oil requirements are the same. Refer to the “Maintenance Procedures” section of this manual for the proper quality and viscosity engine oil. Starting The characteristics of E-85 fuel make it unsuitable for use when ambient temperatures fall below 0°F. In the range of 0°F to 32°F, you may experience an increase in the time it takes for your engine to start, and a deterioration in drivability (sags and/or hesitations) until the engine is fully warmed up.

STARTING AND OPERATING 319

Maintenance If you operate the vehicle using E-85 fuel, follow Sched- ule B in the maintenance schedule section of this manual.

CAUTION!

Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect drivability.

Cruising Range Because E-85 fuel contains less energy per gallon than gasoline, you will experience an increase in fuel con- sumption. You can expect your MPG and your driving range to decrease by about 30% compared to gasoline operation. Replacement Parts Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with correct ethanol com- patible parts.

CAUTION!

Replacing fuel system components with non-ethanol compatible components can damage your vehicle.

320 STARTING AND OPERATING

VEHICLE LOADING

Certification Label As required by National Highway Traffic Safety Admin- istration Regulations, your vehicle has a certification label affixed to the driver’s side door.

This label contains the month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR) front and rear, and Vehicle Identification Number (VIN). A Month-Day-Hour (MDH) number is included on this label and shows the Month, Day, and Hour of manufacture. The bar code that appears on the bottom of the label is your Vehicle Identification Number (VIN). Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options, and cargo. The label also specifies maximum capacities of front and rear axle systems. Total load must be limited so that GVWR is not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck can carry including the weight of the driver, all passengers, options, and cargo.

Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded. Each axle GAWR is determined by the component in the system with the lowest load carrying capacity (axle, springs, tires, or wheels). Heavier axles or suspension components sometimes specified by purchasers for increased durability do not necessarily increase the vehicle’s GVWR. Tire Size This is the minimum allowable tire size for your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed.

STARTING AND OPERATING 321

Inflation Pressure (Cold) This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR. Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added. Loading The actual total weight and the weight of the front and rear of your vehicle at the ground can best be determined by weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commer- cial scale to insure that the GVWR has not been exceeded. The weight on the front and rear of the vehicle should

322 STARTING AND OPERATING

then be determined separately to be sure that the load is properly distributed over front and rear axle. Weighing the vehicle may show that the GAWR of either the front or rear axles has been exceeded but the total load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to front as appropriate until the specified weight limitations are met. Store heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving. Improper weight distribution can have an adverse effect on the way your vehicle steers and handles and the way the brakes operate.

WARNING!

Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. This could cause you to lose control. Also, overloading can shorten the life of your vehicle.

A loaded vehicle is shown in the following example. Note that neither GVWR nor GAWR capabilities are exceeded. Overloading can cause potential safety hazards and shorten service life. NOTE: The weights shown in this chart are not the weights for your vehicle. Also, the amount of load added to both the front and rear axles can be computed

after the vehicle has been weighed both in its ⴖcurb weightⴖ condition, and in its ⴖloaded and ready for operationⴖ condition. Gross Vehicle Weight Rating (GVWR) 6500 LBS.

STARTING AND OPERATING 323

TRAILER TOWING In this section you will find safety tips and information on limits to the type of towing you can reasonably do with your vehicle. Before towing a trailer carefully re- view this information to tow your load as efficiently and safely as possible. To maintain warranty coverage, follow the requirements and recommendations in this manual concerning ve- hicles used for trailer towing. Common Towing Definitions The following trailer towing related definitions will assist you in understanding the following information: Gross Vehicle Weight Rating (GVWR) The GVWR is the total allowable weight of your vehicle. This includes driver, passengers, cargo and tongue weight. The total load must be limited so that you do not exceed the GVWR.

324 STARTING AND OPERATING

Gross Trailer Weight (GTW) The gross trailer weight (GTW) is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or temporary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. The recom- mended way to measure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale. Gross Combination Weight Rating (GCWR) The gross combination weight rating (GCWR) is the total permissible weight of your vehicle and trailer when weighed in combination. (Note that GCWR ratings in- clude a 68 kg (150 lbs) allowance for the presence of a driver).

Gross Axle Weight Rating (GAWR) The GAWR is the maximum capacity of the front and rear axles. Distribute the load over the front and rear axles evenly. Make sure that you do not exceed either front or rear GAWR.

WARNING!

It is important that you do not exceed the maximum front or rear GAWR. A dangerous driving condition can result if either rating is exceeded. You could lose control of the vehicle and have an accident.

Tongue Weight (TW) The downward force exerted on the hitch ball by the trailer. In most cases it should not be less than 10% or more than 15% of the trailer load. You must consider this as part of the load on your vehicle.

Frontal Area The maximum height and maximum width of the front of a trailer. TSC (Trailer Sway Control) – If Equipped • Trailer Sway Control – Electronic TSC uses sensors in the vehicle to recognize a swaying trailer and will take the appropriate actions to attempt to stop the sway. The system will reduce engine power and apply individual brakes that will counter act the sway of the trailer. TSC will become active automatically once the swaying trailer is recognized. No driver action is re- quired. TSC can not stop all trailers from swaying. Always use caution when towing a trailer and follow the tongue weight recommendations. Even if your vehicle is equipped with electronic trailer sway control, mechanical sway control is recommended when appropriate for the size of your trailer.

STARTING AND OPERATING 325

• Trailer Sway Control – Mechanical The trailer sway control is a telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the truck. These kind of hitches are the most popular on the market today and they’re commonly used to tow small- and medium-sized trailers. Weight-Distributing Hitch A weight-distributing system works by applying lever- age through spring (load) bars. They are typically used for heavier loads, to distribute trailer tongue weight to the tow vehicle’s front axle and the trailer axle(s). When

326 STARTING AND OPERATING

used in accordance with the manufacturers’ directions, it provides for a more level ride, offering more consistent steering and brake control thereby enhancing towing safety. The addition of a friction / hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distributing (load equalizing) hitch are recommended for heavier Tongue Weights (TW) and may be required depending on Vehicle and Trailer configuration / loading to comply with gross axle weight rating (GAWR) requirements.

WARNING!

An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, braking per- formance, and could result in an accident. Weight Distributing Systems may not be compatible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Recreational Vehicle dealer for additional information.

Trailer Towing Weights (Maximum Trailer Weight Ratings)

Never exceed the maximum tongue weight stamped on your bumper or trailer hitch.

STARTING AND OPERATING 329

NOTE: For additional trailer towing information (maxi- mum trailer weight ratings) refer to the following website addresses: • http:// www.dodge.com/towing. • http:// www.dodge.ca (Canada). Trailer and Tongue Weight Always load a trailer with 60% to 65% of the weight in the front of the trailer. This places 10% to 15% of the Gross Trailer Weight (GTW) on the tow hitch of your vehicle. Loads balanced over the wheels or heavier in the rear can cause the trailer to sway severely side to side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents.

Consider the following items when computing the weight on the rear axle of the vehicle: • The tongue weight of the trailer.

330 STARTING AND OPERATING

put in or on your vehicle.

• The weight of any other type of cargo or equipment • The weight of the driver and all passengers. NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the Tire and Loading Information plac- ard in the Tire Safety Information Section of this manual. Towing Requirements To promote proper break-in of your new vehicle driv- etrain components the following guidelines are recom- mended:

CAUTION!

• Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage your vehicle. • During the first 500 miles (805 km) of trailer

towing, limit your speed to 50 mph (80 km/h).

Perform the maintenance listed in Section 8 of this manual. When towing a trailer, never exceed the GAWR, or GCWR, ratings.

WARNING!

Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that is not fully secured, dynamic load shifts can occur that may be difficult for the driver to control. You could lose control of your vehicle and have an accident. • When hauling cargo or towing a trailer, do not over- load your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, suspension, chas- sis structure or tires.

STARTING AND OPERATING 331

• Safety chains must always be used between your vehicle and trailer. Always connect the chains to the frame or hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. • Vehicles with trailers should not be parked on a grade. When parking, apply the parking brake on the tow vehicle. Put the tow vehicle automatic transmission in P for Park. With a manual transmission, shift the transmission into reverse. And with four-wheel-drive vehicles, make sure the transfer case is not in neutral. Always, block or ⬙chock⬙ the trailer wheels.

• GCWR must not be exceeded. • Total weight must be distributed between the tow vehicle and the trailer such that the following four ratings are not exceeded: 1. GVWR

332 STARTING AND OPERATING

2. GTW 3. GAWR 4. Tongue weight rating for the trailer hitch utilized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight as a percentage of total trailer weight).

Towing Requirements — Tires − Do not attempt to tow a trailer while using a compact

spare tire.

− Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to the Tires–General Information section of this manual on Tire Pressures for proper tire inflation procedures.

− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to the Tires–General Information section of this manual on Tread Wear Indicators for the proper inspection procedure.

− When replacing tires refer to the Tires–General Infor- mation section of this manual on Replacement Tires for proper tire replacement procedures. Replacing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits. Towing Requirements — Trailer Brakes − Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury.

− Also, check the trailer tires for proper tire inflation

pressures before trailer usage.

− An electronically actuated trailer brake controller is required when towing a trailer with electronically

actuated brakes. When towing a trailer equipped with a hydraulic surge actuated brake system, an electronic brake controller is not required.

− Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs (907 kg).

CAUTION!

If the trailer weighs more than 1,000 lbs (454 kg) loaded, it should have its own brakes and they should be of adequate capacity. Failure to do this could lead to accelerated brake lining wear, higher brake pedal effort, and longer stopping distances.

STARTING AND OPERATING 333

WARNING!

Do not connect trailer brakes to your vehicle’s hy- draulic brake lines. It can overload your brake sys- tem and cause it to fail. You might not have brakes when you need them and could have an accident. Towing any trailer will increase your stopping dis- tance. When towing you should allow for additional space between your vehicle and the vehicle in front of you. Failure to do so could result in an accident.

Towing Requirements — Trailer Lights & Wiring Whenever you pull a trailer, regardless of the trailer size, stop lights and turn signals on the trailer are required for motoring safety. The Trailer Tow Package may include a 4 and 7 pin wiring harness. Use a factory approved trailer harness and connector.

334 STARTING AND OPERATING

NOTE: Do not cut or splice wiring into the vehicles wiring harness. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

7- Pin Connector

Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic.

4 - Pin Connector

If using a manual transmission vehicle for trailer towing, all starts must be in FIRST gear to avoid excessive clutch slippage. Towing Tips — Automatic Transmission The “D” range can be selected when towing. However, if frequent shifting occurs while in this range, the “TOW HAUL” feature should be selected. NOTE: Using the “TOW HAUL” feature while operat- ing the vehicle under heavy operating conditions will improve performance and extend transmission life by reducing excessive shifting and heat build up. This action will also provide better engine braking. The automatic transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. See Schedule “B” in section 8 of this manual for transmission fluid change intervals.

STARTING AND OPERATING 335

NOTE: Check the automatic transmission fluid level before towing. Towing Tips — Tow/Haul (If Equipped) To reduce potential for automatic transmission overheat- ing, turn the “TOW HAUL” feature ON when driving in hilly areas or shift the transmission to Drive position 2 on more severe grades. Towing Tips — Electronic Speed Control (If Equipped) − Don’t use in hilly terrain or with heavy loads. − When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you can get back to cruising speed.

− Use speed control in flat terrain and with light loads to

maximize fuel efficiency.

336 STARTING AND OPERATING

Towing Tips — Cooling System To reduce potential for engine and transmission over- heating, take the following actions: − City Driving When stopped for short periods of time, put transmission in neutral and increase engine idle speed. − Highway Driving Reduce speed. − Air Conditioning Turn off temporarily. − refer to Cooling System Operating information in the Maintenance section of this manual for more informa- tion.

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. 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. 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. NOTE: Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated wheel nuts. 6. Using the wheel wrench, finish tightening the nuts in a crisscross pattern. Correct nut tightness is 135 ± 10 ft. lbs. (183 ± 14 N·m) dynamic torque. If in doubt about the

tightness, have them checked with a torque

correct 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, tools and the extra tire and wheel in the places provided.

7. Remove wheel blocks. Do not install chrome or alu- minum wheel center caps on the spare wheel. This may result in cap damage.

It cannot be overtightened. Push against the tire several times to be sure it is firmly in place.

JUMP STARTING PROCEDURES

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.

WHAT TO DO IN EMERGENCIES 353

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.

354 WHAT TO DO IN EMERGENCIES

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!

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.

WARNING!

WARNING!

WHAT TO DO IN EMERGENCIES 355

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. NOTE: For off-road recovery, it is recommended to use both of the front tow hooks to minimize the risk of damage to the vehicle.

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.

356 WHAT TO DO IN EMERGENCIES

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). 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 363

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

364 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 365

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.

366 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 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. 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.

MAINTAINING YOUR VEHICLE 367

CAUTION!

Overfilling or underfilling the crankcase will cause oil aeration or loss of oil pressure. This could dam- age your engine.

368 MAINTAINING YOUR VEHICLE

Change Engine Oil Road conditions and your style 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). • More than 50% of your driving is at sustained high • Trailer towing, Taxi, Police or delivery service (com- • 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. NOTE: Under no circumstances should oil change in- tervals exceed 6,000 miles (10 000 km) or 6 months whichever comes first. 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.

MAINTAINING YOUR VEHICLE 369

American Petroleum Institute (API) Engine Oil Identification Symbol

This symbol means that the oil has been certified by the American Petroleum Institute (API). The manufacture only recommends API Certified engine oils.

Engine Oil Viscosity (SAE Grade) SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low tempera- ture starting and vehicle fuel economy. Your engine oil filler cap also shows the recommended engine oil viscosity for your vehicle. For information on engine oil filler cap location, see the Engine Compartment illustration in this section.

370 MAINTAINING YOUR VEHICLE

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 You may use synthetic engine oils provided the recom- mended oil quality requirements are met, and the recom- mended maintenance intervals for oil and filter changes are followed. 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 Tension 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 371

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.

372 MAINTAINING YOUR VEHICLE

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 373

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.

Intentional tampering with emissions control in civil penalties being assessed

374 MAINTAINING YOUR VEHICLE

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.

Maintenance Free Battery The top of the maintenance free battery is permanently sealed. You will never have to add water, nor is periodic maintenance required.

WARNING!

• Battery fluid is a corrosive acid solution and can burn or even blind you. Don’t allow battery fluid to contact your eyes, skin or clothing. Don’t lean over a battery when attaching clamps. If acid splashes in eyes or on skin, flush the area imme- diately with large amounts of water. • Battery gas is flammable and explosive. Keep flame or sparks away from the battery. Don’t use a booster battery or any other booster source with an output greater than 12 volts. Don’t allow cable clamps to touch each other. • Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.

MAINTAINING YOUR VEHICLE 375

CAUTION!

• 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. • If a “fast charger” is used while battery is in vehicle, disconnect both vehicle battery cables before 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

376 MAINTAINING YOUR VEHICLE

include cleaning of the condenser fins and a performance test. Drive belt tension should also be checked at this time.

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.⬙

MAINTAINING YOUR VEHICLE 377

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.

378 MAINTAINING YOUR VEHICLE

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

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. Always fill the reservoir with wind- shield washer fluid (not radiator 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.

MAINTAINING YOUR VEHICLE 379

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.

380 MAINTAINING YOUR VEHICLE

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.

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

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. Never try to open a cooling system pressure cap when the radia- tor is hot.

Engine Coolant Checks Check the 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 the front of the A/C condenser for any

MAINTAINING YOUR VEHICLE 381

accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the condenser. Check the coolant recovery bottle tubing for brittle rub- ber, cracking, tears, cuts and tightness of the connection at the bottle and radiator. Inspect the entire system for leaks. With the engine at normal operating temperature (but not running), check the cooling system pressure cap for proper vacuum sealing by draining a small amount of coolant from the radiator drain cock. If the cap is sealing properly, the engine coolant (antifreeze) will begin to drain from the coolant recovery bottle. DO NOT RE- MOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT. Cooling System — Drain, Flush and Refill At the intervals shown on the Maintenance Schedules, the system should be drained, flushed and refilled.

382 MAINTAINING YOUR VEHICLE

If the solution is dirty or contains a considerable amount of sediment, clean and flush with a reliable cooling system cleaner. Follow with a thorough rinsing to remove all deposits and chemicals. Properly dispose of old antifreeze solution. Selection Of Coolant Use only the manufacturers recommended coolant, refer to Fluids, Lubricants and Genuine Parts for correct coolant type.

CAUTION!

Mixing of coolants other than specified HOAT en- gine coolants, may result in engine damage and may decrease corrosion protection. If a non-HOAT cool- ant is introduced into the cooling system 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 Propylene Glycol based coolants is not recommended.

Adding Coolant Your vehicle has been built with an improved engine coolant that allows extended maintenance intervals. This coolant can be used up to 5 Years or 100,000 miles before replacement. To prevent reducing this extended mainte- nance period, it is important that you use the same coolant throughout the life of your vehicle. Please review these recommendations for using Hybrid Organic Addi- tive Technology (HOAT) coolant. When adding coolant, a minimum solution of 50% rec- ommended Mopar Antifreeze/ Coolant 5 Year/100,000
Mile Formula HOAT (Hybrid Organic Additive Technol- ogy), or equivalent, in 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.

MAINTAINING YOUR VEHICLE 383

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. Cooling System Pressure Cap The 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 cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.

384 MAINTAINING YOUR VEHICLE

WARNING!

• The warning words “DO NOT OPEN HOT” on the cooling system pressure cap are a safety pre- caution. Never add coolant when the engine is overheated. Do not loosen or remove the cap to cool an overheated engine. Heat causes pressure to build up in the cooling system. To prevent scalding or injury, do not remove the pressure cap while the system is hot or under pressure. • Do not use a pressure cap other than the one specified for your vehicle. Personal injury or engine damage may result.

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. To prevent ingestion by animals or children

do not store ethylene glycol based engine coolant in open containers or allow it to remain in puddles on the ground. If ingested by a child, contact a physician immediately. Clean up any ground spills immediately. Coolant Level The coolant bottle provides a quick visual method for determining that the coolant level is adequate. With the engine cold, the level of the coolant in the coolant recovery bottle should be between the ranges indicated on the bottle. The radiator normally remains completely full, so there is no need to remove the radiator cap unless checking for coolant freeze point or replacing coolant. Advise your service attendant of this. As long as the engine operating temperature is satisfactory, the coolant bottle need only be checked once a month.

When additional coolant is needed to maintain the proper level, it should be added to the coolant bottle. Do not overfill. Points To Remember NOTE: When the vehicle is stopped after a few miles (a few kilometers) of operation, you may observe vapor coming from the front of the engine compartment. This is normally a result of moisture from rain, snow, or high humidity accumulating on the radiator and being vapor- ized when the thermostat opens, allowing hot coolant to enter the radiator. If an examination of your engine compartment shows no evidence of radiator or hose leaks, the vehicle may be safely driven. The vapor will soon dissipate. • Do not overfill the coolant recovery bottle.

MAINTAINING YOUR VEHICLE 385

• Check coolant freeze point in the radiator and in the coolant recovery bottle. If antifreeze needs to be added, contents of coolant recovery bottle must also be protected against freezing. • If frequent coolant additions are required, or if the level in the coolant recovery bottle does not drop when the engine cools, the cooling system should be pres- sure tested for leaks. • Maintain coolant concentration at 50% HOAT engine coolant (minimum) and distilled water for proper corrosion protection of your engine which contains aluminum components. • Make sure that the radiator and coolant recovery bottle overflow hoses are not kinked or obstructed. • Keep the front of the radiator clean. If your vehicle is equipped with air conditioning, keep the front of the condenser clean, also.

386 MAINTAINING YOUR VEHICLE

• Do not change the thermostat for summer or winter operation. If replacement is ever necessary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory coolant performance, poor gas mileage, and increased emissions.

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, 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. 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! Check ventilating hose for indication of damage or plugging with deposits. Replace if necessary. Brake System

the intervals specified.

If

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.

MAINTAINING YOUR VEHICLE 387

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.

388 MAINTAINING YOUR VEHICLE

WARNING!

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.

CAUTION!

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.

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:

MAINTAINING YOUR VEHICLE 389

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

390 MAINTAINING YOUR VEHICLE

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.

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.

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.

MAINTAINING YOUR VEHICLE 391

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.
