At Least Twice a Year
Restraint System Check
Make sure the safety belt warning 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.)
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
“Automatic Transaxle” in the Index. A fluid loss
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, and any folding
seat hardware. Part
D tells you what to use. More
frequent lubrication may be required when exposed to
a corrosive environment.

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.
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. 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.
Brake-Transaxle Shift Interlock (BTSI) 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. 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.

A C A UTION:
-
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 transaxle 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.
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.
