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 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 Distance Driving
  2. Dusty Conditions
  3. Extended Use Of Brakes
  4. Salt Or Other Corrosive Materials On The Roads
  5. Rough Or Muddy Roads
  6. Extended Idling Or Low Speed Operation
  7. Extended Operation In Extreme Temperatures

CAMSHAFT TIMING BELT

CAUTIONFailure to replace a faulty camshaft timing belt may result in serious engine damage.

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".

Many manufacturers changed their maintenance and warranty schedules in the mid-1980's to reflect timing belt inspection and/or replacement at 50,000-60,000 miles. Most service interval schedules in this manual reflect these changes.

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

Replace camshaft timing belt at 60,000 mile intervals.

SERVICE LABOR TIMES

Note. Labor times are provided, where available, within appropriate SERVICE INTERVAL table in SCHEDULED SERVICES article.

SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)

Note. See the AIR BAG RESTRAINT SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT Section.

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.

WARNINGTo avoid injury from accidental air bag deployment, read and carefully follow all warnings and service precautions. See appropriate AIR BAG RESTRAINT SYSTEM article in the ACCESSORIES/SAFETY EQUIPMENT section.
CAUTIONDisconnect negative battery cable before servicing any air bag system, steering column or passenger side dash component. After any repair, turn ignition key to the ON position from passenger's side of vehicle in case of accidental air bag inflation

AIR CONDITIONING SERVICING

CAUTIONAvoid breathing R-134a refrigerant and PAG lubricant vapors, exposure may irritate eyes, nose and throat. To remove R-134a from system use R-134a recycling equipment that meets SAE J2210 specifications. If accidental system discharge occurs, ventilate work area before resuming service.
WARNINGR-134a service equipment or vehicle A/C systems SHOULD NOT be pressure tested or leak tested with compressed air. Some mixtures of air/R134a have shown to be combustible at elevated pressures. These mixtures are dangerous and may cause fire and/or explosions. See the appropriate A/C SYSTEM GENERAL SERVICING article in the AIR CONDITIONING & HEAT section.

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 the BRAKES Section.
  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

WARNINGWhen battery is disconnected, vehicles equipped with computers may lose memory data. When battery power is restored, driveability problems may exist on some vehicles. These vehicles may require a relearn procedure. See appropriate COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section below.

REPLACING BLOWN FUSES

CAUTIONBefore 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

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

CATALYTIC CONVERTER

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

WARNINGMany solid state electrical components can be damaged by static electricity (ESD). Some will display a warning label, but many will not. Discharge personal static electricity by touching a metal ground point on the vehicle prior to servicing any ESD sensitive component.

ENGINE OIL

CAUTIONNever use non-detergent or straight mineral oil.

FUEL SYSTEM SERVICE

WARNINGRelieve fuel system pressure prior to servicing any fuel system component (fuel injection models).

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.

HEADLIGHT RETRACTOR

CAUTIONIf headlight retractor freezes during cold weather operation, DO NOT attempt to force mechanism. Headlights should be kept raised at all times in cold weather. To raise them, use only headlight retractor switch. DO NOT use headlight switch.

RADIATOR CAP

CAUTIONAlways disconnect the fan motor when working near the radiator fan. The fan is temperature controlled and could start at any time even when the ignition key is in the OFF position. DO NOT loosen or remove radiator cap when cooling system is hot.

RADIATOR FAN

WARNINGKeep 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.
