Steering Column Lock Check
While parked, and with the parking brake set, try to turn
the
key to LOCK in each shift lever position.
With an automatic transmission, the key should turn
to LOCK only when the shift lever is in PARK (P).
With a manual transmission, the key should turn to
LOCK only if you push the key in farther, while
turning it towards
LOCK.
On vehicles with a key release lever, try to turn the key
to LOCK without pressing the lever. The key should
turn to LOCK only when you press the key lever.
On all vehicles, the key should come out only in LOCK.
Parking Brake and Automatic Transmission
PARK (P) Mechanism Check
/d 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 transmission in NEUTRAL (N), slowly remove
foot pressure from the regular brake pedal.
Do this
until the vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding ability:
Shift to
PARK (P). Then release all brakes. If your
vehicle is four-wheel
drive, be sure the transfer case
is not in NEUTRAL (N).
Underbody Flushing Service
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.

Part 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 repairs are
completed at once.
Proper procedures to perform these services may be
found
in a Geo service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front- Wheel-Drive
Axle
Boot and Seal Inspection
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.
Exhaust System Inspection
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.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.

Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts as
needed. Replace any cables that have high effort
or
excessive wear. Do not lubricate accelerator and cruise
control cables.
Rear Axle (All) and Front Axle
(Four-wheel Drive) Service
Check the gear lubricant level and add if needed. See
“Rear
Axle” and “Four-wheel Drive” in the Index.
A fluid loss may indicate a problem. Check the
system(s), and repair
the system(s) if needed. Refer
to “Scheduled Maintenance Services,” earlier in this
section, to determine when to change the lubricant.
Brake System Inspection
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.
Clutch System Service
Check clutch pedal free travel and adjust as necessary.
See “Clutch Adjustment”
in the Index.
