“Section D: Recommended Fluids and Lubricants” lists some
products
GM recommends to help keep your vehicle properly
maintained. These products,
or their equivalents, should be
used whether you do the work yourself or have it done.
‘Section E: Maintenance Record” provides a place for you to
record the maintenance performed on your vehicle. Whenever
any maintenance is performed,
be sure to write it down in this
section. This will help you determine when your next
maintenance should be done. In addition, it
is a good idea to
keep your maintenance receipts. They may be needed to
qualify your vehicle for warranty repairs.
Section A: Scheduled Maintenance
Sewices
Using Your Maintenance Schedule
This section tells you the maintenance services you should
have done and when you should schedule them.
Your Pontiac
dealer knows your vehicle best and wants you to be happy with
it. If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will perform the
work using genuine
GM parts.
These schedules are for vehicles that:
carry passengers and cargo within recommended limits.
You will find these limits on your vehicle’s Tire-Loading
Information Label. S’ee “Loading Your Vehicle” in the
Index.
are driven on reasonable road surfaces within legal driving
limits.
use the recommended unleaded fuel. See “Fuel” in the
Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is right
for your vehicle. Here’s how to decide which schedule to
follow:
Schedule I
Is any one of these true for your vehicle?
Most trips are less than 4 miles (6 km).
Most trips are less than 10 miles (16 km) when outside
temperatures are below freezing.
The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
You operate your vehicle in dusty areas.
You tow a trailer. (With some models, you shouldn’t ever
tow a trailer. See “Towing a Trailer” in the Index.)
If any one (or more) of these is true for your driving, follow
Schedule I.
Schedule I1
Follow Schedule I1 only if none of the above conditions is true.

Maintenance Schedule
Explanation of Scheduled Maintenance
Services
Following are explanations of the services listed in Schedule I
and Schedule 11.
The proper fluids and lubricants to use are listed in Section D.
Make sure whoever services your vehicle uses these. All parts
should be replaced and all necessary repairs done before you or
anyone else drives the vehicle.
NOTE: To determine your engine’s displacement and code, see
“Engine Identification”
in the Index.
1.
2.
Engine Oil and Filter Change* -- Always use SH or SG
Energy Conserving I1 oils of proper viscosity. The “SH” or
“SG” designation may be shown alone or in combination
with others, such as “SH/CD,” “SH, SG, CD,” “SG/CD,”
etc. To determine the preferred viscosity for your vehicle’s
engine (e.g., SAE 5W-30 or SAE 10W-30), see “Engine
Oil”
in the Index.
Chassis Lubrication -- Lubricate suspension and steering
linkage. Lubricate the transaxle shift linkage, underbody
contact points and linkage.
3.
4.
5.
Tire and Wheel Rotation and Inspection -- For proper
wear and maximum tire life, rotate your tires following the
instructions
in this manual. See “Tires, Inspection &
Rotation” in the Index. Check the tires for uneven wear or
damage. If you see irregular or premature wear, check the
wheel alignment, Check for damaged wheels also.
Engine Accessory Drive Belt(s) Inspection -- Inspect the
belt(s) for cracks, fraying, wear and proper tension. Replace
as needed. (Belts can have many small cracks
in individual
ribs without affecting performance.)
Cooling System Service* -- Drain, flush and refill the
system with new or approved recycled coolant conforming
to
GM Specification 1825M. Keep coolant at the proper
mixture as specified. See “Coolant”
in the Index. This
provides proper freeze and boil protection, corrosion
inhibitor level and maintains proper engine operating
temperature.
Inspect hoses and replace if they are cracked, swollen or
deteriorated. Tighten screw-type hose clamps. Clean the
outside of the radiator and air conditioning condenser. Wash
the pressure cap and neck.
To help ensure proper operation, we recommend a pressure
test of both the cooling system and the pressure cap.
