SEVERE & NORMAL SERVICE DEFINITIONS

Note. Use the Severe Service schedule if the vehicle to be serviced is operated under ANY (one or more) of these conditions

Service is recommended at mileage intervals based on vehicle operation. Service schedules are based on the following primary operating conditions

Normal Service

1. Driven More Than 10 Miles Daily
2. No Operating Conditions From Severe Service Schedule

Severe Service (Unique Driving Conditions)

1. Repeated Short Trips (Less Than 10 Miles)
2. Severe Dust
3. Severe Cold Weather
4. Areas Using Road Salt (Or Similar Materials)
5. Driving On Rough And/Or Muddy Roads

CAMSHAFT TIMING BELT

The condition of camshaft drive belts should always be checked on vehicles which have more than 50,000 miles. Although some manufacturers do not recommend belt replacement at a specified mileage, others require it at 60,000-100,000 miles. A camshaft drive belt failure may cause extensive damage to internal engine components on most engines, although some designs do not allow piston-to-valve contact. These designs are often called "Free Wheeling".

Belts or components should be inspected and replaced if any of the following conditions exist

1. Cracks Or Tears In Belt Surface
2. Missing, Damaged, Cracked Or Rounded Teeth
3. Oil Contamination
4. Damaged Or Faulty Tensioners
5. Incorrect Tension Adjustment

WHEEL & TIRE SPECIFICATIONS

Wheel and tire information can be found on the label attached to the edge of the driver's door. Tire information can also be found on the label inside the glove compartment.

WHEEL TIGHTENING

Tighten wheel lug nuts to 80 ft. lbs. (110 N.m).

BATTERY SPECIFICATIONS

If battery is replaced, new battery should be of same group number as shown on original battery's label.

SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)

Note. See the AIR BAGS article in ACCESSORIES/SAFETY EQUIPMENT.

Modifications or improper maintenance, including incorrect removal and installation of the Supplemental Restraint System (SRS), can adversely affect system performance. DO NOT cover, obstruct or change the steering wheel horn pad in any way, as such action could cause improper function of the system. Use only plain water when cleaning the horn pad. Solvents or cleaners could adversely affect the air bag cover and cause improper deployment of the system.

AIR CONDITIONER

Ensure the air conditioning system is sufficiently charged before using. Prolonged use of an under-charged system may damage the compressor.

AIR CONDITIONING SERVICING

ANTI-LOCK BRAKE SYSTEM

The anti-lock brake system contains electronic equipment that can be susceptible to interference caused by improperly installed or high output radio transmitting equipment. Since this interference could cause the possible loss of the anti-lock braking capability, such equipment should be installed by qualified professionals.

On models equipped with anti-lock brake systems, ALWAYS observe the following cautions

1. DO NOT attempt to bleed hydraulic system without first referring to the appropriate ANTI-LOCK BRAKE SYSTEM article in BRAKES.
2. DO NOT mix tire sizes. As long as tires remain close to the original diameter, increasing the width is acceptable. Rolling diameter must be identical for all 4 tires. Some manufacturers recommend tires of the same brand, style and type. Failure to follow this precaution may cause inaccurate wheel speed readings.
3. Use ONLY recommended brake fluids. DO NOT use silicone brake fluids in an ABS-equipped vehicle.

BATTERY WARNING

REPLACING BLOWN FUSES

Before replacing a blown fuse, remove ignition key, turn off all lights and accessories to avoid damaging the electrical system. Be sure to use fuse with the correct indicated amperage rating. The use of an incorrect amperage rating fuse may result in a dangerous electrical system overload.

BRAKE PAD WEAR INDICATOR

Indicator will cause a squealing or scraping noise, warning that brake pads need replacement.

CATALYTIC CONVERTER

Continued operation of vehicle with a severe malfunction could cause converter to overheat, resulting in possible damage to converter and vehicle.

Any modification to the exhaust system on turbo models, which reduces exhaust backpressure, will lead to lean fuel mixtures and excessive spark advance. This could cause serious engine damage.

ELECTROSTATIC DISCHARGE SENSITIVE (ESD) PARTS

ENGINE OIL

FUEL SYSTEM SERVICE

HALOGEN BULBS

Halogen bulbs contain pressurized gas which may explode if overheated. DO NOT touch glass portion of bulb with bare hands. Eye protection should be worn when handling or working around halogen bulbs.

RADIATOR & CONDENSER FINS

Radiator and condenser fins are very thin and easily damaged. Exercise extreme care when working around them.

RADIATOR CAP

RADIATOR FAN

Keep hands away from radiator fan. Fan is controlled by a thermostatic switch which may come on or run for up to 15 minutes even after engine is turned off.

WASHER FLUID RESERVOIR

DO NOT use a vinegar/water combination in the windshield washer; it will damage the pump. Prolonged operation of the washer without fluid may damage the pump.

WARRANTY INFORMATION

FUSE PANEL LOCATION

The fuse box is located under dashboard on driver's side. Underhood fuse panel is located in engine compartment beside battery. Cars equipped with anti-lock brake system have a third fuse box for ABS in front of the engine compartment on passenger's side.
