Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air conditioning
system
in your vehicle needs refrigerant, be sure the proper refrigerant is
used.
If you’re not sure, ask your GM dealer. For additional information, see
your “Warranty and Owner Assistance Information’’ booklet.
NOTICE:
R-134A refrigerant is not compatible with R-12 refrigerant in
an air conditioning system. R-12 in an R-134A system will cause
compressor failure, refrigerant oil sludge, or poor air
conditioning system performance.

Protection
Have you purchased the GM Protection Plun? The Plun supplements your
new vehicle warranties. See your GM dealer for detui1.s.
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your vehicle in good
working condition, but also helps
the environment. All recommended
maintenance procedures are important. Improper vehicle maintenance or the
removal
of important components can significantly affect the quality of the
air we breathe. Improper fluid levels or even
the wrong tire inflation can
increase the level
of emissions from your vehicle. To help protect our
environment, and
to help keep your vehicle in good condition, please
maintain your vehicle properly.

If your engine has more than one emissions classification, the classification
is determined by the Gross Vehicle Weight Rating (GVWR) of your vehicle
as shown on the Certification Label. See “Loading Your Vehicle” in the
Index.
Once you’ve determined your engine type and,
if necessary, emissions
classification, you’ll need
to decide which of the two schedules is right for
your vehicle. See Definitions for Maintenance Schedule I and Maintenance
Schedule I1 following.
Schedule I Definition - Gasoline Engines With Light Duty
Emissions
Follow Maintenance Schedule I if any one of these is true for your vehicle:
0 Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly
important when outside temperatures are below freezing.

Maintenance Schedule I - Gasoline Engines With
Light Duty Emissions
The services shown in this schedule up to 60,000 miles (100 000 km) should
be performed after
60,000 miles (100 000 km) at the same intervals.
Footnotes
The California Air Resources Board has determined that the failure to
perform this maintenance item will
not nullify the emission warranty or
limit recall liability prior
to the completion of vehicle useful life. We,
however, urge that all recommended maintenance services be performed at
the indicated intervals and the maintenance be recorded.
** Drive axle service:
0 Locking Differential - Drain fluid and refill at first engine oil change.
At subsequent oil changes, check fluid level and add fluid as needed. If
driving
in dusty areas or towing a trailer, drain fluid and refill every
15,000 miles (25 000 km).
Standard Differential - Check fluid level and add fluid as needed at
every
oil change. If driving in dusty areas or towing a trailer, drain
fluid and refill every
15,000 miles (25 000 km).
More frequent lubrication may be required for heavy-duty or off-road
use.
