ITEM SERVICE
NO.
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 6
Rotation in the hdex. Check the
tires for uneven wear or damage.
If
you see irregular or premature wear,
check the wheel alignment. Check for

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
parlung 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.

Section C: Periodic Maintenance Inspections
Listed below are inspections and services which should be performed at least twice a year (for instance, each spring and fall).
You should let your GM dealer’s service department or other qualified service center
do these jobs. Make sure any necessary
Bepairs are completed at once.

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 hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other bralte
parts, including calipers, parking brake, etc. Check parking bralte adj\
ustment. 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 bralte system warning light stays on or comes on, something may be wrong with the
brake system. See
Brake System Warning Light in the Index. If your vehicle is equipped with anti-
lock brakes and the anti-lock bralte system warning
light stays on, comes on or flashes, something
may be wrong with the anti-lock brake system. See
Anti-Lock Brake System Warning Light in the Index.
