urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.

At Least Twice a Year At Least Once
a Year
Restraint System Check Key Lock Cylinders
Service
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.) Lubricate the key lock
cylinders with the lubricant
specified in Part
D.
Body Lubrication Service
Lubricate all hood hinges, hood prop rod pivot, fuel
filler door, rear compartment hinges, latches, locks and
any moving seat hardware.
Part D tells you what to use.
More frequent lubrication may be required when
exposed
to a corrosive environment.
Wiper Blade Check Starter Switch 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.
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.
I
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

3.
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.
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-Transmission Shift Interlock (BTSI) Check
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 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.
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.
0 The key should turn to LOCK only when the shift
lever is in PARK (P).
The key should come out only in LOCK.
