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
- Driven More Than 10 Miles Daily
- No Operating Conditions From Severe Service Schedule
Severe Service (Unique Driving Conditions)
- Extended Idling Or Low Speed Operation
- Frequent Short Trips Of Less Than 7 Miles
- Extended Operation In Dusty Or Sandy Conditions
- Trailer Towing Operations
- Driving In Mountainous Conditions
CAMSHAFT TIMING BELT (TURBO MODELS)
| CAUTION | Failure 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
- Cracks Or Tears In Belt Surface
- Missing, Damaged, Cracked Or Rounded Teeth
- Oil Contamination
- Damaged Or Faulty Tensioners
- Incorrect Tension Adjustment
Replace timing belt every 50,000 miles.

OXYGEN SENSOR WARNING LIGHT (760 GLE)
- Warning light in the dash will illuminate every 30,000 miles as a reminder to replace the oxygen sensor. After replacing sensor reset mileage counter.
- On 1986 760 GLE models, locate unit under dash (follow wires or small cable from back of speedometer to unit). Remove retaining screw and switch cover. Press reset button. Ensure reminder light is out. Install switch cover.
- On 1987-90 models there is no warning light used for oxygen sensor service intervals.
SERVICE INTERVAL REMINDER LIGHT 1988-90 (IF EQUIPPED)
- Service interval reminder light will come on at 5000 mile intervals to indicate oil and filter change is scheduled. After changing oil and filter, reset mileage counter.
- To reset counter on 1988-90 760, remove rubber grommet to left of odometer. Using a small screwdriver, depress reset knob. (Scheme 8)

BATTERY SPECIFICATIONS
| CAUTION | When 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 COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section. |
Gasoline engine vehicles use batteries with a 66 amp hour rating. Diesel engine vehicles use batteries with a 88 amp hour rating.
SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)
Note. See the AIR BAGS 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.
| WARNING | To avoid injury from accidental air bag deployment, read and carefully follow all warnings and service precautions. See appropriate AIR BAGS article in ACCESSORIES/SAFETY EQUIPMENT. |
| CAUTION | Disconnect 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 |
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAR WARNING
Note. For information on air bag DIAGNOSIS & TESTING or DISPOSAL PROCEDURES, see AIR BAGS article in the ACCESSORIES/SAFETY EQUIPMENT Section.
System circuit is grounded by 2 screws beneath the driver's seat. DO NOT use these screws to ground any other accessory. DO NOT ground any other components near this system.
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
- DO NOT attempt to bleed hydraulic system without first referring to the appropriate ANTI-LOCK BRAKE SYSTEM article in the BRAKES Section.
- 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.
- Use ONLY recommended brake fluids. DO NOT use silicone brake fluids in an ABS-equipped vehicle.
BATTERY WARNING
| WARNING | When 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 COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION section. |
REPLACING BLOWN FUSES
| CAUTION | 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 SYSTEM
| CAUTION | If brake warning light comes on while driving it indicates a low fluid level or failure in one of the braking circuits. If the brake pedal can be depressed further than normal it is an indication that one of the brake circuits is not functioning. Stop vehicle and check brake reservoir fluid level. If level is below MIN mark, DO NOT drive vehicle. Have it towed to a repair shop. If level is between the MIN and MAX marks, proceed cautiously to a repair shop. |
BRAKE PAD WEAR INDICATOR
| CAUTION | Indicator will cause a squealing or scraping noise, warning that brake pads need replacement. |
CATALYTIC CONVERTER
| CAUTION | Continued operation of vehicle with a severe malfunction could cause converter to overheat, resulting in possible damage to converter and vehicle. |
| CAUTION | 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
| WARNING | Many 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
| CAUTION | Never use non-detergent or straight mineral oil. |
FUEL SYSTEM SERVICE
| WARNING | Relieve fuel system pressure prior to servicing any fuel system component (fuel injection models). |
HALOGEN BULBS
| WARNING | 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 CAP
| CAUTION | Always 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
| WARNING | 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. |
TURBOCHARGED MODELS
| CAUTION | Do not race engine immediately after starting. When stopping engine, allow engine to idle for approximately 60 seconds before shutting it off. Failure to do so may cause turbocharger damage due to lack of oil flowing to the turbocharger bearings. |
WHEELS & TIRES
Only wheels tested and approved by the manufacturer should be used on models equipped with Air Dam aerodynamic components.
