items, refer to

The following text and illustrations describe the details of the required
scheduled maintenance services.

Engine Oil and Filter Change
For the engine oil and filter changing procedure, refer to
Engine Oil and Oil Filter Replacement
in Engine
Mechanical - 2.2 L or
Engine Oil and Oil Filter Replacement
in Engine Mechanical - 4.3 L.
For information on the correct engine oil quality and viscosity, refer
to the following.
Engine Oil Quality, United States and Canada
Important: When adding to, or changing the engine oil, use ONLY oils of the proper
quality.
Oils of the proper quality for the vehicle can be identified by looking
for the STARBURST symbol. The STARBURST symbol indicates that the oil has
been certified by the American Petroleum Institute (API), and
is preferred for use in gasoline engines.
Engine Oil Viscosity, United States and Canada
Notice: Using oils of any viscosity other than those recommended
could result in engine damage. When choosing an oil, consider the range of
temperatures the vehicle will be operated in before the next oil change.
Then, select the recommended oil viscosity.
The recommended oil viscosity for all vehicles is SAE 5W-30.
Engine oil viscosity (thickness) has an effect on the fuel economy and
the cold-weather operation (starting and oil flow). Lower viscosity engine
oils can provide better fuel economy and cold-weather performance.
However, higher temperature weather condition require higher viscosity
engine oils for satisfactory lubrication. When the temperature is
consistently above -18°C (0°F), SAE
10W-30 can be used. SAE 20W-50 or oils of other viscosity rating
or quality designations are NOT recommended for use in any
GMC vehicle at any time.
Chassis Lubrication
Notice: Do not lubricate the parking brake cables. Lubrication destroys the
plastic coating on the cable.
Lubricate transaxle shift linkage. Lubricate the park brake
guides, underbody contact points and linkage.
