At Least Twice a Year Automatic Transmission Check
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 covers, and
have them repaired or replaced.
(The air bag system
does not need regular maintenance.)
Fluid Level Check
Check the transfer case, axle differential(s) and
automatic
or manual transmission fluid levels and add as
needed. See “Transfer Case,” “Axle, Rear,” “Axle,
Front” and “Automatic Transmission” or “Manual
Transmission”
in the Index. A fluid loss in these systems
could indicate a problem. Have the system inspected and
repaired
at once.
Check the transmission fluid level; add if needed. See
“Automatic Transmission”
in the Index. A fluid IOSS may
indicate
a problem. Check the system and repair if needed.
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 body door hinges. Also lubricate all hinges
and latches, including those for the hood, rear
compartment, glove box door, console door 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 Brake-Transmission Shift Interlock (BTSI) Check
(Automatic Transmission)
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
2. Firmly apply both the parking brake (see “Parking
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.
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.
around the vehicle.
When you are doing this check,
the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
I. 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).
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 ON 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.

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.
