Carbon Monoxide Warnings

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning:

† Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas, which can kill. Never run the engine in a closed area, such as a garage, and never sit in a parked vehicle with the engine running for an extended period. If the vehicle is stopped in an open area with the engine running for more than a short period, adjust the ventilation system to force fresh, outside air into the vehicle.

† Guard against carbon monoxide with proper mainte- nance. Have the exhaust system inspected every time the vehicle is raised. Have any abnormal conditions repaired promptly. Until repaired, drive with all side windows fully open. † Keep the trunk closed when driving your vehicle to prevent carbon monoxide and other poisonous ex- haust gases from entering the vehicle.

ADDING FUEL

Fuel Filler Cap (Gas Cap) The gas cap is located behind the fuel filler door on the left side of the vehicle. If the gas cap is lost or damaged, be sure the replacement cap is designed for use with this vehicle.

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 or pillar. 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 indicates the Month, Day, and Hour of manufacture. The bar code that appears on the bottom of the label is your Vehicle Identification Number (VIN).

362 STARTING AND OPERATING

Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options, trailer tongue weight, and cargo. The label also specifies maxi- mum capacities of front and rear axle systems (GAWR). Total load must be limited, so GVWR, and front and rear GAWR are 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 components in the system with the lowest load carrying capacity (axle, springs, tires, or wheels). Heavier axles or suspension components sometimes specified by purchasers for in- creased durability does not necessarily increase the vehi- cle’s GVWR. Tire Size The tire size on the Label represents the actual tire size on 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. Inflation Pressure 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 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

STARTING AND OPERATING 363

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 the heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving. Improper weight distributions can have an adverse effect on the way your vehicle steers and handles and the way the brakes operate.

CAUTION!

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.

364 STARTING AND OPERATING

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 review 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 Gross Vehicle Weight Rating (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.

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 9loaded and ready for operation9 condition. The recommended 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.

WARNING!

it

If the Gross Trailer Weight (GTW) is 3,500 lbs. (1 587
kg) or more, is mandatory to use a weight- distributing hitch to ensure stable handling of your vehicle. If you use a standard weight- carrying hitch, you could lose control of your vehicle and cause an accident.

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 150 lbs (68 kg) allowance for the presence of a driver). Gross Axle Weight Rating (GAWR) The Gross Axle Weight Rating (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.

STARTING AND OPERATING 365

Tongue Weight (TW) Tongue weight (TW) is 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 Frontal area is the maximum height and maximum width of the front of a trailer. Trailer Sway Control — Electronic Refer to “TSC (Trailer Sway Control)” under “Electronic Brake Control System” in this section for information on this system. 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.

366 STARTING AND OPERATING

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

STARTING AND OPERATING 371

Consider the following items when computing the weight on the rear axle of the vehicle: † The tongue weight of the trailer. † The weight of any other type of cargo or equipment † The weight of the driver and all passengers.

put in or on your vehicle.

372 STARTING AND OPERATING

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” placard for the maximum combined weight of occupants and cargo for your vehicle. Towing Requirements To promote proper break-in of your new vehicle drivetrain components the following guidelines are recommended:

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 that is will not shift during travel. When traile- ring 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 overload your vehicle or trailer. Overloading can cause a loss of control, poor performance, or damage to brakes, axle, engine, transmission, steering, suspen- sion, chassis structure, or tires. † 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” (Park). With a manual transmission, shift the transmission into “R” (Reverse). Always, block or 9chock9 the trailer wheels.

† GCWR must not be exceeded.

STARTING AND OPERATING 373

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

374 STARTING AND OPERATING

− Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires–General Information” in this section for infor- mation on tire pressures and for proper tire inflation procedures.

− Also, check the trailer tires for proper tire inflation

pressures before trailer usage.

− Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires–General Infor- mation” in this section for information on tread wear indicators and for the proper inspection procedure.

− When replacing tires, refer to “Tires–General Informa- tion” in this section for information on replacement tires and for the 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.

− 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).

STARTING AND OPERATING 375

Towing Requirements — Trailer Lights & Wiring Whenever you pull a trailer, regardless of the trailer size, stoplights 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. NOTE: Do not cut or splice wiring into the vehicles wiring harness.

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.

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.

376 STARTING AND OPERATING

The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

4 - Pin Connector

7- Pin Connector

Towing Tips Before setting out on a trip, practice turning, stopping, and backing the trailer in an area located away from heavy traffic. 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, you will want to activate the TOW/HAUL feature. Refer to “Au- tomatic Transmission” in this section for additional in- formation. NOTE: Using the TOW/HAUL feature while operating the vehicle under heavy operating conditions will im- prove performance and extend transmission life by re- ducing excessive shifting and heat build up. This action will also provide better engine braking.

STARTING AND OPERATING 377

If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the auto- matic transmission fluid and filter according to the interval specified for “police, taxi, fleet, or frequent trailer towing” in the “Maintenance Schedule” in this manual. Towing Tips — TOW/HAUL To reduce potential for automatic transmission overheat- ing, press the “TOW HAUL” button when driving in hilly areas or shift the transmission to Drive position “2” on more severe grades. Refer to “Automatic Transmis- sion” in this section for additional information. 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.

378 STARTING AND OPERATING

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

maximize fuel efficiency.

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” under “Maintenance Pro- cedures” in Section 7 of this manual for more informa- tion.

RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)

Towing – 2WD Models Recreational towing is not allowed.

CAUTION!

Towing with the rear wheels on the ground can result in severe transmission damage.

Towing — 4WD Models The transfer case must be shifted into Neutral (N) for recreational towing. The Neutral (N) selection button is located at the top 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.

CAUTION!

† The Automatic Transmission must be in “P” (Park) position for recreational towing. The Manual Transmission (if equipped) must be in gear (for example, 4th gear) for recreational towing. Failure to follow these procedures can cause severe trans- mission and/or transfer case damage. † Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is used when recreational towing. † Before recreational towing, perform the procedure outlined under “Shifting into Neutral” to be cer- tain that the transfer case is fully in Neutral (N). Otherwise, internal damage will result. † Do not use a bumper mounted clamp-on tow bar on your vehicle. The bumper face bar will be damaged.

384 WHAT TO DO IN EMERGENCIES

IF YOUR ENGINE OVERHEATS In any of the following situations, you can reduce the potential for overheating by taking the appropriate ac- tion. † On the highways — Slow down. † In city traffic — While stopped, put transmission in N

(Neutral), but do not increase engine idle speed.

NOTE: There are steps that you can take to slow down an impending overheat condition. If your air conditioner is on, turn it off. The air conditioning system adds heat to the engine cooling system and turning off the A/C removes this heat. You can also turn the Temperature Control to maximum heat, the Mode Control to floor, and the Fan Control to High. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system.

CAUTION!

Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads “H,” pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on the “H,” and you hear continuous chimes, turn the engine off immediately, and call for service.

JACKING AND TIRE CHANGING

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. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift. † The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas.

WHAT TO DO IN EMERGENCIES 385

Jack Location The scissor-type jack and tire changing tools are located in the cargo compartment behind a trim cover on the left rear trim panel. The latch is located at the bottom of the trim cover.

3.7L ENGINE COMPARTMENT

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 399

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.

400 MAINTAINING YOUR VEHICLE

Loose Fuel Filler Cap Message If the vehicle diagnostic system determines that the fuel filler cap in loose, improperly installed, or damaged, a “gASCAP” message will display in the instrument clus- ter. Tighten the gas cap until a “clicking” sound is heard. This is an indication that the gas cap is properly tight- ened. Press the trip odometer reset button to turn off the message. 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 Light) is functioning and is not on when the engine is running, and that the OBD (On Board Diagnostic) system is ready for testing. Normally, the OBD system will be ready. The OBD system may not be ready if your vehicle was recently serviced, if you recently had a dead battery, or a battery replacement. If the OBD system should be determined not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key actuated test, which you can use prior to going to the test station. To check if your vehicle’s OBD system is ready, you must do the following: 1. Insert your ignition key into the ignition switch.

2. Turn the ignition to the ON position, but do not crank or start the engine. 3. If you crank or start the engine, you will have to start this test over. 4. As soon as you turn your key to the ON position, you will see your MIL symbol come on as part of a normal bulb check. 5. Approximately 15 seconds later, one of two things will happen:

a. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn off the ignition key or start the engine. This means that your vehicle’s OBD system is not ready and you should not proceed to the I/M station.

MAINTAINING YOUR VEHICLE 401

b. The MIL will not flash at all and will remain fully illuminated until you turn off the ignition key or start the engine. 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 authorized dealer or repair facility. If your vehicle was recently serviced or had a battery failure or replacement, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD system to update. A recheck with the above test routine may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD system is ready or not ready, if the MIL symbol is illuminated during normal vehicle operation, you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL symbol is on with the engine running.

402 MAINTAINING YOUR VEHICLE

REPLACEMENT PARTS Use of genuine Mopart 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-Mopart parts for maintenance and repairs will not be covered by the manufacturer’s warranty.

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. Only do 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 engine lubrication, 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 403

CAUTION!

Do not overfill the engine. Overfilling the engine will cause oil aeration, which can lead to loss of oil pressure and an increase in oil temperature. This could damage your engine. Also, be sure the oil fill cap is replaced and tightened after adding oil.

404 MAINTAINING YOUR VEHICLE

Change Engine Oil The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Refer to “Maintenance Schedule” in Section 8 of this manual for information on this system. NOTE: Under no circumstances should oil change intervals exceed 6,000 miles (10 000 km) or 6 months, whichever occurs first.

Engine Oil Selection For best performance and maximum protection under all types of operating conditions, the manufacturer recom- mends engine oils that are API Certified and meet the requirements of DaimlerChrysler Material Standard MS- 6395.

American Petroleum Institute (API) Engine Oil Identification Symbol

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

Engine Oil Viscosity SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your engine. For information on engine oil filler cap location, refer to the “Engine Com- partment” illustration in this section.

Lubricants, which do not have both, the engine oil certification mark and the correct SAE viscosity grade number 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 Oil The manufacturer strongly recommends against the ad- dition of any additives (other than leak detection dyes) to the engine oil. Engine oil is an engineered product and its performance may be impaired by supplemental addi- tives.

MAINTAINING YOUR VEHICLE 405

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 All of this manufacturer’s engines have a full-flow type disposable oil filter. Use a filter of this type for replace- ment. The quality of replacement filters varies consider- ably. Only high quality filters should be used to assure most efficient service. Mopart Engine Oil Filters are high quality oil filters and are recommended.

406 MAINTAINING YOUR VEHICLE

Drive Belts — Check Condition and Tension Belt tension is controlled by means of an automatic tensioner. Therefore, no belt tension adjustments are required. However, belt and belt tensioner condition should be inspected periodically and replaced if re- quired. Improper belt tension can cause belt slippage and failure. Low generator belt tension can cause battery failure. Inspect belts for evidence of cuts, cracks, glazing, or frayed cords and replaced if there is indication of dam- age, which could result in belt failure. Also, check belt routing to make sure there is no interference between the belts and other engine components. See your authorized dealer for service.

Spark Plugs Spark plugs must fire properly to assure engine perfor- mance and emission control. New plugs should be in- stalled at the specified mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Malfunctioning spark plugs can damage the cata- lytic converter. Refer to “Fluids, Lubricants, and Genuine Parts” in this section for the proper type of spark plug for use in your vehicle. Engine Air Cleaner Filter Refer to the “Maintenance Schedule” in Section 8 of this manual for engine air cleaner filter maintenance inter- vals. NOTE: Be sure to follow the “dusty or off-road condi- tions” maintenance interval if applicable.

WARNING!

The air induction system (air cleaner, hoses, etc) can provide a measure of protection in the case of engine backfire. Do not remove the air induction system (air cleaner, hoses, etc) unless such removal is necessary for repair or maintenance. Make sure that no one is near the engine compartment before starting the vehicle with the air induction system (air cleaner, hoses, etc) removed. Failure to do so can result in serious personal injury.

MAINTAINING YOUR VEHICLE 407

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. See your authorized dealer for service. 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.

408 MAINTAINING YOUR VEHICLE

CAUTION!

WARNING!

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

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 exhaust system. Do not park or operate your vehicle in areas where your exhaust system can contact anything that can burn.

In unusual situations involving grossly malfunctioning engine operation, a scorching odor may suggest severe and abnormal catalyst overheating. If this occurs, safely bring the vehicle to a complete stop, turn off the engine, and allow it to cool. Service, including a tune up to manufacturer’s specifications, should be obtained imme- diately.

To minimize the possibility of catalytic converter dam- age: † 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 the engine by pushing or towing the † Do not idle the engine with any ignition coil connec- † Do not idle the engine for prolonged periods during very rough idle or malfunctioning operating condi- tions.

† Do not allow vehicle to run out of fuel.

MAINTAINING YOUR VEHICLE 409

Crankcase Emission Control System Proper operation of this system depends on freedom from sticking or plugging due to deposits. As vehicle mileage builds up, the PCV valve and passages may accumulate deposits. If a valve is not working properly, replace it with a new valve. DO NOT ATTEMPT TO CLEAN THE OLD PCV VALVE! Check ventilation hose for indication of damage or plugging deposits. Replace if necessary. Maintenance-Free Battery Your vehicle is equipped with a maintenance-free battery. You will never have to add water, nor is periodic main- tenance required.

410 MAINTAINING YOUR VEHICLE

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.

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 posi- tive (+) and negative (-) and identified on the battery case. Cable clamps should be tight on the terminal posts and free of corrosion. † If a “fast charger” is used while the battery is in the vehicle, disconnect both vehicle battery cables before connecting the charger to battery. Do not use a “fast charger” to provide starting voltage as battery damage can result.

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.

MAINTAINING YOUR VEHICLE 411

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 additional 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 technician.

412 MAINTAINING YOUR VEHICLE

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. NOTE: Use only manufacturer approved A/C System Sealers, Stop Leak Products, Seal Conditioners, Compres- sor Oil, and Refrigerants. A/C Air Filter — If Equipped Refer to the “Maintenance Schedule” in Section 8 of this manual for A/C Air Filter service intervals.

WARNING!

Do not remove the A/C Air Filter while the blower is operating or personal injury may result.

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 manufacturer’s 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” in this section for the correct fluid type. NOTE: Upon initial start-up in cold weather, the power steering pump may make noise for a short period of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and does not in any way damage the steering system. Driveline and Steering Component Lubrication All driveline and steering components are sealed and do not require lubrication. Driveshafts are not serviceable. Body Lubrication Locks and all body pivot points, including such items as seat tracks, doors, tailgate and hood hinges, should be lubricated periodically to assure quiet, easy operation and to protect against rust and wear. Prior to the appli- cation of any lubricant, the parts concerned should be

MAINTAINING YOUR VEHICLE 413

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 Mopart Lock Cylinder Lubricant directly into the lock cylinder. Windshield Wiper Blades Clean the rubber edges of the wiper blades and the windshield periodically with a sponge or soft cloth and a mild non-abrasive cleaner or use the washer solvent. This will remove accumulations of salt, waxes, or road film and help reduce streaking and smearing.

414 MAINTAINING YOUR VEHICLE

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. Make sure that they are not frozen to the glass before turning them on to avoid damaging the blade. Keep the blade rubber out of contact with petroleum products such as engine oil, gasoline, etc. NOTE: Always refer to the wiper blade packaging for specific installation instructions. Many wiper blade re- placements fit multiple vehicles.

Windshield & Rear Window Washers The windshield and rear window washers share the same fluid reservoir. The fluid reservoir is located in the front of the engine compartment. Be sure to check the fluid level in the reservoir at regular intervals. Fill the reservoir with windshield washer solvent (not radiator antifreeze) and operate the system for a few seconds to flush out the residual water. When refilling the washer fluid reservoir, take some washer fluid and apply it to a cloth or towel and wipe clean the wiper blades, this will help blade performance. 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 415

fumes to seep into the passenger compartment. In addi- tion, 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. Refer to “Exhaust Gas” in the “Safety Tips” section of this manual.

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.

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 an authorized technician inspect the complete exhaust system and adjacent body areas for broken, damaged, deteriorated, or mispositioned parts. Open seams or loose connections could permit exhaust

† When working near the radiator cooling fan, dis- connect the fan motor lead or turn the ignition switch to the LOCK position. The fan is tempera- ture controlled and can start at any time the ignition switch is in the ON position. † 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 radiator is hot.

Coolant Checks 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 the front of the A/C condenser (if equipped) or radiator for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the A/C con- denser (if equipped) or the back of the radiator core. Check the engine cooling system hoses for brittle rubber, cracking, tears, cuts, and tightness of the connection at the coolant recovery 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 coolant will begin to drain from the coolant recovery bottle. DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT. Cooling System — Drain, Flush, and Refill The system should be drained, flushed, and refilled at the intervals shown in the “Maintenance Schedule” in Sec- tion 8 of this manual. 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 manufacturer’s recommended coolant. Re- fer to “Fluids, Lubricants, and Genuine Parts” in this section for the correct fluid type.

CAUTION!

† Mixing of coolants other than specified HOAT engine coolants, may result in engine damage and may decrease corrosion protection. If a non-HOAT coolant 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.

418 MAINTAINING YOUR VEHICLE

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 (160
000 km) before replacement. To prevent reducing this extended maintenance period, it is important that you use the same coolant throughout the life of your vehicle. Please review these recommendations for using Hybrid Organic Additive Technology (HOAT) coolant. When adding coolant: † The manufacturer

recommends using Mopart Antifreeze/Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology). † Mix a minimum solution of 50% HOAT engine coolant and distilled water. Use higher concentrations (not to exceed 70%) if temperatures below 234°F (237°C) are anticipated.

† Use only high purity water such as distilled or deion- ized 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. 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.

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 scald- ing 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 en- gine damage may result.

MAINTAINING YOUR VEHICLE 419

Disposal of Used 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 idling, and warm to normal operating tempera- ture, the level of the coolant in the 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

420 MAINTAINING YOUR VEHICLE

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 (kilometers) of operation, you may observe vapor coming from the front of the engine compartment. This is nor- mally 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 bottle. † Check coolant freeze point in the radiator and in the coolant recovery bottle. If coolant needs to be added, contents of coolant recovery bottle must also be pro- tected 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 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. † 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 cooling performance, poor gas mileage, and increased emissions.

Hoses and Vacuum/Vapor Harnesses Inspect surfaces of hoses and nylon tubing for evidence of heat and mechanical damage. Hard or soft spots, brittle rubber, cracking, tears, cuts, abrasions, and exces- sive swelling indicate deterioration of the rubber. Pay particular attention to those hoses nearest to high heat sources such as the exhaust manifold. Inspect hose routing to be sure hoses do not touch any heat source or moving component that may cause heat damage or mechanical wear.

MAINTAINING YOUR VEHICLE 421

Insure nylon tubing in these areas has not melted or collapsed. Inspect all hose connections such as clamps and cou- plings to make sure they are secure and no leaks are present. Components should be replaced immediately if there is any evidence of wear or damage that could cause failure. Fuel System The Electronic Fuel Injection high-pressure fuel system’s tubes, special connectors, connections, and clamps have unique material characteristics that provide adequate sealing and resist attack by deteriorated gasoline. You are urged to use only the manufacture specified tubes, connections, and clamps, or their equivalent in material and specification, in any fuel system servicing.

422 MAINTAINING YOUR VEHICLE

Brake System In order to assure brake system performance, all brake system components should be inspected periodically. Suggested service intervals can be found in the “Mainte- nance Schedule” in Section 8 of this manual.

WARNING!

Riding the brakes can lead to brake failure and possibly an accident. Driving with your foot resting or riding on the brake pedal can result in abnormally high brake temperatures, excessive lining wear, and possible brake damage. You wouldn’t have your full braking capacity in an emergency.

Brake and Power Steering System Hoses When servicing the vehicle for scheduled maintenance, inspect the surface of the hoses and nylon tubing for evidence of heat and mechanical damage. Hard and

brittle rubber, cracking, tears, cuts, abrasions, and exces- sive swelling suggest deterioration of the rubber. Particu- lar attention should be made to examining those hose surfaces nearest to high heat sources, such as the exhaust manifold. 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: † Often, 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 a hose is replaced based on leakage.

† Inspect the brake hoses whenever the brake system is serviced and at every engine oil change. 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 resulting in a possibility of a burst failure.

WARNING!

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

Master Cylinder - Brake Fluid Level Check Check the fluid level in the master cylinder immediately if the brake system warning light indicates system fail- ure.

MAINTAINING YOUR VEHICLE 423

Check the fluid level in the master cylinder when per- forming underhood services. Clean the top of the master cylinder area before removing the cap. If necessary, add fluid to bring the fluid level up to the requirements described on the brake fluid reser- voir. Overfilling of fluid is not recommended because it may cause leaking in the system. Fluid level can be expected to fall as the brake pads wear. Brake fluid level should be checked when pads are replaced. However, low fluid level may be caused by a leak and a checkup may be needed. Use only manufacturer’s recommended brake fluid. Re- fer to “Fluids, Lubricants, and Genuine Parts” in this section for the correct fluid type.

424 MAINTAINING YOUR VEHICLE

WARNING!

† Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. † Use of a brake fluid that has a lower initial boiling point than the recommended product or a brake fluid that is unidentified as to FMVSS specifica- tion may result in sudden brake failure during hard prolonged braking. You could have an accident.

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

CAUTION!

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

Clutch Hydraulic System — Manual Transmission (If Equipped) The clutch hydraulic system is fed by a segregated volume of fluid within the brake system master cylinder reservoir. In the event of leakage or wear, use only manufacturer’s recommended brake fluid. Refer to “Flu- ids, Lubricants, and Genuine Parts” in this section for the correct fluid type.

Automatic Transmission

Fluid Level Check Your vehicle is equipped with a capped dipstick tube that is sealed and it should not be tampered with. Your authorized dealer has the proper tools to ensure that the fluid level is set properly.

CAUTION!

Using a transmission fluid other than the manufac- turer’s recommended fluid may cause deterioration in transmission shift quality and/or torque converter shudder. Using a transmission fluid other than that recommended by the manufacturer will result in more frequent fluid and filter changes. Refer to “Fluids, Lubricants, and Genuine Parts” in this sec- tion for the correct fluid type.

MAINTAINING YOUR VEHICLE 425

Fluid and Filter Changes Change the automatic transmission fluid and filter at the intervals shown in the “Maintenance Schedule” in Sec- tion 8 of this manual. In addition, change the fluid and filter if the transmission is disassembled for any reason. NOTE: Be sure to follow the “police, taxi, fleet, off-road, or frequent trailer towing” maintenance interval if appli- cable. Special Additives Automatic Transmission Fluid (ATF) is an engineered product and its performance may be impaired by supple- mental additives. Therefore, do not add any fluid addi- tives to the transmission. The only exception to this policy is the use of special dyes to aid in detecting fluid leaks. In addition, avoid using transmission sealers as they may adversely affect seals.

426 MAINTAINING YOUR VEHICLE

Manual Transmission — If Equipped

Fluid Level Check Check the fluid level by removing the fill plug. The fluid level should be between the bottom of the fill hole and a point not more than 3/16” (4.76 mm) below the bottom of the hole. Add fluid, if necessary, to maintain the proper level. Lubricant Selection Use only manufacturer’s recommended manual trans- mission fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in this section for the correct fluid type.

Frequency of Fluid Change Under normal operating conditions, the fluid installed at the factory will give satisfactory lubrication for the life of the vehicle. Fluid changes are not necessary unless the fluid becomes contaminated with water. Change the fluid immediately if contaminated with water. NOTE: Be sure to follow the “trailer tow, snow plow, heavy load, taxi, police, commercial service, off-road, desert, or sustained high speeds during hot weather” maintenance interval if applicable. Transfer Case

Fluid Level Check The fluid level should be to the bottom edge of the fill hole (1) when the vehicle is in a level position.

NOTE: Be sure to follow the “police, taxi, fleet, off-road, or frequent trailer towing” maintenance interval if appli- cable. 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.
