{CAUTION:
Anyone who is up against, or very close to,
any air bag when it in¯ates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle's safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see
Older Children on page 1-28 and Infants
and Young Children on page 1-31.
There is a air bag
readiness light on the
instrument panel, which
shows the air bag symbol.The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See
Air Bag Readiness Light on page 3-26.
Where Are the Air Bags?
The driver's air bag is in the middle of the steering
wheel.

Lockout Protection
Lockout protection is intended to provide enhanced
security and convenience. This feature prevents a driver
who has left the key in the ignition from locking the
doors, using the power door locks while any door
is open.
To override this feature, when the key is in the ignition
and any door is open, press and hold down the
power door lock switch for three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle. If you don't leave the key in
the ignition, or if you use the manual door lock or
the remote keyless entry transmitter, you could still lock
your key inside your vehicle. Always remember to
take your key with you.
Leaving Your Vehicle
If you are leaving your vehicle, open your door and set
the locks from the inside, then get out and close the door.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder. When closing the trunk
lid, close from the center to ensure it fully latches.
{CAUTION:

come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the trunk lid open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªClimate Control
Systemº in the Index.
·If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
