Scheme 8: VIN Code ID Explanation

SHORT TRIP/CITY & LONG TRIP/HIGHWAY SERVICE DEFINITIONS

Note. Starting in the 1996 model year, General Motors has renamed their maintenance schedules; One is referred to as the Short-Trip/City and the other is the Long Trip/Highway schedule. These schedule requirements are similar to the familiar Severe Service and Normal schedules and can be used in place of one another.

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

Severe Service

  1. Short Trips (4 Miles Or Less)
  2. When Most Trips Are Less Than 10 Miles And Outside Temperatures Remain Below Freezing.
  3. Towing Or Heavily Loaded
  4. Severe Dust Conditions
  5. Hot Weather, Stop-And-Go Driving
  6. Extensive Idling Conditions (Taxi Or Delivery Type Service)

Normal Service

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

Note. For more information regarding cooling system service, refer to the 5.7L V8 - VIN [P] article in the ENGINE MECHANICAL section.

SERVICE LABOR TIMES

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

TIRE INFLATION

Tire pressure specification decal is attached to rear face of driver's door. Inflation pressures listed on decal are always cold pressures and must never exceed maximum values molded into tire side wall. These pressures should be used for all driving conditions, as they provide the best balance of fuel economy, tire life, riding comfort and handling.

Note. When using compact spare tire, it must be inflated to 60 psi, and vehicle must not be driven faster than 50 MPH.

WHEEL TIGHTENING

ApplicationFt. Lbs. (N.m)
All100 (140)
(1) Always tighten wheel lug nuts in a crisscross pattern. All wheel lug nuts have right-hand threads.

TIGHTENING SPECIFICATIONS (1)

BATTERY SPECIFICATIONS

CAUTIONWhen 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.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR BAG SYSTEM

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

The SRS has no user-servicable parts. Always have servicing done by an authorized dealer.

When performing maintenance on air bag equipped vehicles always observe proper safety precautions.

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

ANTI-LOCK BRAKE SYSTEM (ABS)

CAUTIONNever mix different diameter tires. On loose or uneven surfaces, the ABS system may require longer stopping distances than conventional brake systems. Exercise caution when removing mud or snow from the wheels so as not to damage the ABS wiring or speed sensors.

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

Indicator 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.

COOLANT (PROPYLENE-GLYCOL FORMULATIONS)

CAUTIONTo avoid possible damage to vehicle use only ethylene-glycol based coolants with a mixture ratio from 44-68% anti-freeze. DO NOT use 100% anti-freeze as it will cause the formation of cooling system deposits. This results in coolant temperatures of over 300° F (149°C) which can melt plastics. 100% anti-freeze has a freeze point of only -8° F (-22°C).
CAUTIONPropylene-Glycol Mixtures has a smaller temperature range than Ethylene-Glycol. The temperature range (freeze-boil) of a 50/50 Anti-Freeze/Water Mix is as follows: Propylene-Glycol -26° F (-32°C) - 257° F (125°C) or Ethylene-Glycol -35° F (-37°C) - 263° F (128°C).
CAUTIONPropylene-Glycol/Ethylene-Glycol Mixtures can cause the destabilization of various corrosion inhibitors. Also Propylene-Glycol/Ethylene-Glycol has a different specific gravity than Ethylene-Glycol coolant, which will result in inaccurate freeze point calculations.

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

WARNINGHalogen 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

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.

RADIATOR FAN WITH TOW PACKAGE

WARNINGKeep hands away from mechanical (fan-clutch) radiator fan.

SPARK PLUGS

Note. Allow engine to cool before removing spark plugs from aluminum cylinder heads.

TAILGATE

WARNINGDO NOT drive vehicle with tailgate open, as carbon monoxide can enter vehicle.

TRACTION CONTROL SYSTEM (IF EQUIPPED)

CAUTIONIf tires are allowed to spin at high speeds when TRACTION OFF light is on, tires can explode. Also, spinning the tires with the warning light on can cause the transaxle to overheat. DO NOT spin wheels above 35 MPH.
