VIN Code ID Explanation. Scheme 3
SHORT TRIP/CITY & LONG TRIP/HIGHWAY SERVICE DEFINITIONS
Note. 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
Service is recommended at mileage intervals based on vehicle operation, emission classification, and Gross Vehicle Weight Rating (GVWR, VIN Position 4). Emission classification is identified by engine VIN code (except diesel-powered vehicles). Manufacturer's Schedules identify items to be serviced based on type of operation. Service schedules are based on the following primary operating conditions
Normal Service/Long Trip/Highway
- No Severe Service Operating Conditions
Severe Service/Short-Trip/City
Note. Use the Severe Service schedule if the vehicle to be serviced is operated under ANY (one or more) of these conditions
- Most Trips Are Less Than 5 To 10 miles (8 To 10 km). This is particularly important when outside temperatures are below freezing.
- Most Trips Include Extensive Idling (Such As Frequent Stop-And-Go Traffic)
- Most Trips Are Through Dusty Areas
- The Vehicle Frequently Tows A Trailer Or Uses A Carrier On Top Of The Vehicle
- The Vehicle Is Used For Delivery Service, Police, Taxi, Or Other Commercial Application

TIRE INFLATION
The tire specification decal is located on rear of the driver's door.
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.
| WARNING | To avoid injury from accidental air bag deployment, read and carefully follow all warnings and service precautions. See appropriate AIR BAG RESTRAINT SYSTEM article in ACCESSORIES/SAFETY EQUIPMENT. |
Modification to the air bag system component or wiring can adversely affect system performance and possibly cause injury.
| CAUTION | The Diagnostic Energy Reserve Module (DERM) can maintain enough voltage to cause a deployment of the inflator module for up to 10 minutes after the ignition switch is turned off and the battery is disconnected. Many of the service procedures require disconnection of the inflator module to avoid an accidental deployment. |
| 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 |
AIR CONDITIONING SERVICING
| WARNING | Avoid 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. |
| WARNING | R-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 AIR CONDITIONING SERVICE article in GENERAL INFORMATION section. |
ANTI-LOCK BRAKE SYSTEM
| CAUTION | 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»(ref-32966) 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.
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 PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning that brake pads need replacement.
CATALYTIC CONVERTER
| CAUTION | To prevent catalytic converter overheating, DO NOT allow engine to idle for more than 20 minutes. |
COOLANT
| CAUTION | All models have DEX-COOL engine coolant installed at the factory. DEX-COOL coolant is a silicate-free coolant that is orange in color. |
Note. It should not be mixed with regular ethylene-glycol coolant. To avoid possible damage to vehicle cooling system, visually check engine coolant color before adding and/or changing engine coolant. Vehicle should have an identification label placed under the hood stating what type coolant is installed.
| WARNING | Do NOT add only plain water to the cooling system. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. The vehicle's coolant warning system is set for the proper coolant mix only. With plain water or the wrong mix, the engine could get too hot, but the overheat warning may not appear. The engine could catch fire and passengers in the vehicle could be seriously injured. |
Use a 50/50 mixture of distilled water and DEX-COOL engine coolant.
ELECTROSTATIC DISCHARGE SENSITIVE (ESD) PARTS
| CAUTION | 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. |
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 FAN
| WARNING | Keep hands away from radiator fan. |

| CAUTION | Due to the different warranties offered in various regions and the variety of after-market extended warranties available, please refer to the warranty package that came with the vehicle to verify all warranty options. |
