Mechanism Check
WHAT TO DO
While parked, and with the parking brake set, try to turn the key to LOCK in each shift lever
position.
With an automatic transaxle, the key should turn to LOCK only when the shift lever is in P
(Park) .
With a manual transaxle, the key should turn to LOCK only when the shift lever is in R
(Reverse).
On vehicles with a key release button, try to turn the key to
LOCK without pressing the button.
The key should turn to
LOCK only with the key button depressed. On all vehicles, the key
should come out only in
LOCK.
Turn the steering wheel to the left and to the right. It should only lock when turned to the right.
~~ ~~ ~
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 ther\
e 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.

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
Jour
GM dealer’s service department or other qualified service center \
do these jobs. Make sure any necessary repairs are completed at once.

and Front-Wheel-

WHAT SHOULD BE DONE
Now and then, make sure all your belts, bucltles, latch plates, retractors, anchorages and
reminder systems are worlting 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 hook-
up, 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.
.-
Check the transaxle fluid level; add if needed. See Manual Transaxle in the Index. A fluid loss
may indicate a problem. Check the system and repair if 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 rot\
ors 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 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 brake 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 anti-lock brake 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.
