At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles,
latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system
parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does
not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning” in the Index.
Air Cleaner Filter Restriction Indicator Check
Your vehicle has an indicator on the engine that lets you
know when the air cleaner filter is dirty and needs
to be
changed. Check indicator at least twice a year or when
your oil is changed. See “Air Cleaner” in
the Index for
more information. Inspect your air cleaner filter restriction indicator more often
if the vehicle is used in
dusty areas or under off road conditions.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
“Manual Transmission” in
the Index. Check the system for
leaks. A fluid loss may indicate a problem. Have the
system inspected and repaired if needed.
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
“Automatic Transmission” in the Index.
A fluid loss
may indicate a problem. Check the system and repair
if needed.
Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
“Hydraulic Clutch Fluid” in the Index. 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 fuel doors, body hood and body door
hinges, tailgate and tailgate handle pivot points, latches,
locks and 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
’ A 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.
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 (N), push the clutch down halfway
and try
to start the engine. The starter should work
only when the clutch
is pushed down all the way to
the floor. If the starter works when the clutch isn’t
pushed all the way down, your vehicle needs service.
1. Before you start, be sure you have enough room
2. Firmly apply both the parking brake (see “Parking
around the vehicle.
Brake” in
the Index if necessary) and the
regular brake.
NOTE: Do not use the accelerator pedal, and be
ready
to turn off the engine immediately if it starts.
Brake-’Ikansmission Shift Interlock (BTSI) Check
(Automatic Transmission)
I A 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. It should be parked on a
level surface.

2. Firmly apply the parking brake (see “Parking Brake”
in the Index if necessary). Parking Brake and Automatic Transmission
PARK (P) Mechanism Check
NOTE: Be ready to apply the regular brake
immediately
if the vehicle begins to move.
3. With the engine off, turn the key to the RUN position,
but don’t 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’s BTSI needs service.
Ignition Transmission Lock Check
While parked, and with the parking brake set, try to turn
the ignition 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 when the shift lever is in REVERSE (R).
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 when you press the key button.
On all vehicles, the key should come out only in LOCK.
I
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’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.
0 To check the PARK (P) mechanism’s holding ability:
With the engine running, shift
to PARK (P). Then
release all brakes.
