Wiper Blade Check
Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades,
if contaminated. Replace wiper blades that are worn
or damaged. SeeWindshield Wiper Blade Replacement
on page 5-49andWindshield and Wiper Blades on
page 5-84for more information.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. SeePart D: Recommended Fluids and
Lubricants on page 6-23.
Manual Transmission Check
It is not necessary to check the transmission fluid level.
Check for leaks. A fluid leak is the only reason for fluid
loss. Have the system inspected and repaired if needed.
Automatic Transmission Check
Check the transmission fluid level; add if needed.
A fluid loss may indicate a problem. Check the
system and repair if needed.
Hydraulic Clutch System Check
Check the fluid level in the brake/clutch reservoir.
SeeHydraulic Clutch on page 5-21. A fluid loss in
this system could indicate a problem. Have the
system inspected and repaired at once.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part D.
Body Lubrication Service
Lubricate all hood latch assemblies, secondary latch,
pivots, spring anchor, release pawl, hood and body
door hinges, rear compartment, and any folding
seat hardware. Part D tells you what to use.
More frequent lubrication may be required when
exposed to a corrosive environment.

Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. SeeParking Brake on page 2-26if necessary.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transmission vehicles, try to start the
engine in each gear. The starter should work only
in PARK (P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever
in NEUTRAL, push the clutch pedal down halfway
and try to start the engine. The starter should
work only when the clutch pedal is pushed down
all the way to the floor. If the starter works when the
clutch pedal is not pushed all the way down, your
vehicle needs service.
Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. SeeParking Brake
on page 2-26if necessary.
Be ready to apply the regular brake immediately
if the vehicle begins to move.
3. With the engine off, turn the ignition to ON/RUN,
but do not start the engine. Without applying the
regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle needs service.
6-20

Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition to LOCK/OFF in each shift lever position.
•With an automatic transmission, the ignition
should turn to LOCK/OFF only when the shift
lever is in PARK (P).
•With a manual transmission, the ignition should
turn to LOCK/OFF only when you press the key
release button.
On all vehicles, the ignition key should come out only
in LOCK/OFF.
Turn the steering wheel to the left and to the right.
It should only lock when turned to the right.

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’s holding ability: 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: With the engine running, shift to PARK (P).
Then release the parking brake followed by the
regular brake.
Underbody Flushing Service
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care

Vehicle Data Recording
and Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the vehicle’s
performance and how it is driven. For example,
your vehicle uses computer modules to monitor
and control engine and transmission performance,
to monitor the conditions for airbag deployment
and deploy airbags in a crash and, if so equipped,
to provide antilock braking to help the driver control the
vehicle. These modules may store data to help your
dealer/retailer technician service your vehicle. Some
modules may also store data about how you operate
the vehicle, such as rate of fuel consumption or average
speed. These modules may also retain the owner’s
personal preferences, such as radio pre-sets, seat
positions, and temperature settings.
