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.
ITEM
NO. SERVICE
1. 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.
2. Chassis Lubrication - Lubricate
suspension and steering linkage.
Lubricate the transaxle shift linkage,
and parking brake cable guides,
underbody contact points and
linkage.
3. 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 E.
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 Inspection
- Inspect the drive belt for cracks,
fraying, wear and proper tension.
Replace as needed.
I
Cooling System Servicee - Drain,
flush and refill the system with new
or approved recycled coolant
conforming to GM Specification
I
1825M. Keep coolant at the proper 1
mixture as specified. See Coolant in
the
Index. This provides proper
freeze and boil protection, corrosion
I
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 tht
pressure cap and neck.
To help ensure proper operation, we
recommend
a pressure test of both the
cooling system and the pressure cap.

CHECK
OR SERVICE WHAT TO DO
I Key Lock Cylinders I Lubricate the key lock cylinders with the lubricant specified in Section D.
I
Body Lubrication Lubricate
all body door hinges, including the liftgate.
Also lubricate all hinges and latches,
including those for the hood, sliding door track, rear compartment, glove box door, console door,
and any folding seat hardware. Section
D tells you what to use.
Starter Switch
CAUTION. When you are doing this check, the vehicle could move suddenly\
. If it does, you
or others could be injured. Follow the steps below.
1. Before you start, be sure you have enough room around the vehicle.
2. Firmly apply both the parking brake (see Parking Brake in the Index if necessary) and the
NOTE:
Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter should work only in P (Park) or N (Neutral). If

Mechanism Check
Underbody Flushing
WHAT TO DO
CAUTION: When you are doing this check, your vehicle could begin to move. You or others
could be injured and property could be damaged. Make sure there is room in front
of your
vehicle in case it begins to
roll. Be ready to apply the regular brake at once should the vehicle
begin to move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake: With the engine running and transaxle in N (Neutral), slowly
remove foot pressure from the regular brake pedal.
Do this until the vehicle is held by the
parking brake only.
To check the P (Park) mechanism’s holding ability: Shift to P (Park). Then release all brakes.
At least every spring, use plain water to flush any corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud and other debris can collect.

WHAT SHOULD BE DONE
~ ~~~
Now and then, make sure all your belts, buckles, latch plates, retractors, anchorages and
reminder systems are working properly. Look for any loose parts or damage.
If you see anything
that might keep
a restraint system from doing its job, have it repaired.
Inspect the front and rear suspension
and steering system for damaged, loose or missing parts,
signs of wear, or lack of lubrication. Inspect the power steering lines and hoses for proper
hookup, binding, leaks, cracks, chafing, etc. Clean and then inspect the drive axle boot seals for
damage, tears or leakage. Replace seals if necessary.
Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken,
damaged, missing or out-of-position parts as well
as open seams, holes, loose connections, or
other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes
into the vehicle. See
Engine Exhaust in the Index.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed.
Inspect the complete system. Inspect brake lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Also inspect
drum brake linings for wear and cracks. Inspect other brake parts, including drums, wheel
cylinders, calipers, parking brake, etc. Check parking brake adjustment.
You may need to have
your brakes inspected more often
if your driving habits or conditions result in frequent braking.
NOTE:
A low brake fluid level can indicate worn disc brake pads which may need to be serviced.
Also, if the brake system warning light stays on or comes on, something may be wrong with the
brake system. See the
Index under Brake System Warning Light. If your anti-lock brake system
warning light stays on or comes on, something may be wrong with the anti-lock brake system.
See the
Index under Anti-Lock Brake System Wawing Light.
