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.)

inserts that appear worn or damaged or that streak or
miss areas
of the windshield. Also see “Wiper Blades,
Cleaning” in the Index.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
“Manual Transmission’’ in the Index. Check for leaks.
A fluid loss may indicate a problem. Have the system
inspected and repaired if needed. 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

Downloaded from www.Manualslib.com manuals search engine 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.
1.
2.
3.
Brake-Transmission Shift Interlock (BTSI) Check (Automatic Transmission)
Before you start, be sure you have enough room
around the vehicle.
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.
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.
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).
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.

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

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 all brakes.
Underbody Flushing Service
At least every spring, use plain water
to flush any
corrosive materials from the underbody. Take
