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, 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
Severe Service
- Short Trips (4 Miles Or Less)
- Freezing Temperatures
- Towing Or Heavily Loaded
- Severe Dust Conditions
- Hot Weather, Stop-And-Go Driving
- Extensive Idling Conditions (Taxi Or Delivery Type Service)
Normal Service
- No Severe Service Operating Conditions

AIR CONDITIONING SERVICING
| 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 AIR CONDITIONING & HEATING section. |
| CAUTION | 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. |
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.
AXLE FLUID
| CAUTION | Axle lubricant should be changed whenever the axle has been submerged in water. Water can enter through the axle vent hole and contaminate the lubricant. |
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.
BATTERY WARNING
| 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 the COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section. |
BRAKE PAD WEAR INDICATOR

CATALYTIC CONVERTER
To prevent catalytic converter overheating, DO NOT allow engine to idle for more than 20 minutes.
COOLANT (DEX-COOL 1995 MODELS)
| CAUTION | Some 1995 build-out models may have DEX-COOL engine coolant installed at the factory. DEX-COOL coolant is orange in color and 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. |
COOLANT (PROPYLENE-GLYCOL FORMULATIONS)
| CAUTION | Propylene-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); Ethylene-Glycol -35° F (-37°C) - 263° F (128°C). |
| CAUTION | Propylene-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. |
To 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. Full strength anti-freeze has a freeze point of only -8° F (-22°C).
DIESEL FUEL ANTI-FUNGAL ADDITIVES
| CAUTION | If fuel contamination due to fungi or other microorganisms is suspected a fuel additive with a biocide may be used. Follow the manufacturers dosage as recommended on product label. Use biocides ONLY when necessary, excessive use can may cause other fuel system problems. |
DIESEL FUEL CONTAMINATION
| WARNING | Diesel fuel system may be contaminated with fungi or other microorganisms. Keep contaminated fuel away from open skin cuts or sores to prevent skin irritation or infection. |
DIESEL FUEL REQUIREMENTS
| CAUTION | All diesel engines are to use Diesel Fuel #2 when the outside temperature is above 20°F (-7°C). In temperatures that are below 20°F (-7°C) use Diesel Fuel #1, this will reduce the chance of the fuel thickening and forming wax. |
Note. A Diesel Fuel #1 & #2 combination (Blended Fuel) may be used, and is recommended for mild winter driving.
JUMP STARTING (TURBO DIESEL)
| WARNING | DO NOT USE a booster battery or power source that has more than 12 volts of power. NEVER USE a 24 volt power source. |
STARTING FLUID USE (TURBO DIESEL)
| WARNING | DO NOT USE starting fluids (ether) or flammable liquids to aid the starting of a Diesel engine. NEVER pour diesel fuel, flammable liquids or starting fluids into the air cleaner canister, air intake or turbocharger housing in an attempt to start the vehicle. A flash fire may result causing personal injury. |
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. |
