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 Transmission’’ in the Index. A fluid
loss
may indicate a problem. Check the system and repair
if needed.

c
,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.
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.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a
level surface.
2.
3.
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.
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
