{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 the part of this manual called ªOlder
Childrenº or ªInfants and Young Children.ºThere is an 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 3-25for more information.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
PASS-KeyžII
Your vehicle is equipped
with the PASS-KeyžII
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
žII is a passive
theft-deterrent system.
It works when you insert or
remove the key from the
ignition.PASS-Key
žII uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS-Key
žII system senses that someone is
using the wrong key, it shuts down the vehicle's
starter and fuel systems. For about three minutes, the
starter won't work and fuel won't go to the engine.
If someone tries to start your vehicle again or uses
another key during this time, the vehicle will not start.
This discourages someone from randomly trying different
keys with different resistor pellets in an attempt to
make a match.
The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY warning
light on the instrument panel is ¯ashing, the key may be
dirty or wet. Turn the ignition off.
2-17

Clean and dry the key. Wait about three minutes and try
again. If the starter still won't work, and the key
appears to be clean and dry, wait about three minutes
and try another ignition key. At this time, you may
also want to check the fuse. See
Fuses and Circuit
Breakers on page 5-89. If the starter won't work with the
other key, your vehicle needs service. If your vehicle
does start, the ®rst ignition key may be faulty. See your
dealer or a locksmith who can service the PASS-Key
žII.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY warning light on the instrument panel will
then come on. But you don't have to wait three minutes
before trying another ignition key.
See your dealer or a locksmith who can service the
PASS-Key
žII to have a new key made.If you're ever driving and the SECURITY warning light
comes on, you will be able to restart your engine if
you turn it off. Your PASS-Key
žII system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
PASS-Key
žII system.
If you lose or damage a PASS-Key
žII ignition key, see
your dealer or a locksmith who can service
PASS-Key
žII to have a new key made. Also, seeRoadside Assistance Program on page 7-6for more
information.
