1-28 Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
air bag systems. To purchase a service manual, see
ªService and Owner Publicationsº in the Index.
CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag systems. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag systems do not need regular maintenance.

2-9 Rear-Door Child Security Locks
Your vehicle is equipped with rear-door child security
locks that help prevent passengers from opening the rear
doors of your vehicle from the inside. To use one of
these locks:
1. Open one of the rear doors.
2. On the inside of the rear
door will be a lock.
Insert your door key into
this lock and turn it
upward. This will
engage the safety lock.
To disengage the feature,
turn the lock downward.
3. Close the door.
4. Do the same thing to the other rear door lock.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on, unlock
the door from the inside and then open the door from
the outside.
Lockout Protection Feature
This feature prevents a driver who has left the key in the
vehicle's ignition from locking the doors by using the
power door locks while any door is open. The feature

You may override the lockout protection feature by
holding the power door lock switch in the lock position
for more than three seconds while the key is in the
ignition and any door is open.
Remember, this feature can't guarantee that you'll
never be locked out of your vehicle. If you use the
manual door lock or if you don't leave the key in the
ignition, you could still lock your keys inside your
vehicle. Always remember to take your keys with you.
Leaving Your Vehicle

door and set the locks from inside. Then get out and
close the door. (Also see ªDelayed Lockingº in this
