Vehicle Security
This vehicle has theft-deterrent
features; however, they do not
make it impossible to steal.
Immobilizer
SeeRadio Frequency Statement on
page 13‑22 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized
Automotive Security System)
theft-deterrent system.
PASS-Key III+ is a passive
theft deterrent system.
The system is automatically armed
when the key is removed from the
ignition. You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using the
wrong key, it shuts down the
vehicle's starter and fuel systems.
The starter will not work and fuel will
stop being delivered to the engine.
Anyone using a trial-and-error
method to start the vehicle will be
discouraged because of the high
number of electrical key codes.
If the engine does not start and the
security message comes on, the
key may have a damaged
transponder. Turn the ignition off
and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. At this time,
you may also want to check the
instrument panel PASS KEY fuse.
If the engine still does not start with
the other key, the vehicle needs
service. If the vehicle does start, the
first key may be faulty. See your
dealer or a locksmith who can
service the PASS-Key III+ to have a
new key made. See
Fuses and
Circuit Breakers on page 10‑41.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. This procedure is for
learning additional keys only. If all
the currently programmed keys are
lost or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.

Keys, Doors, and Windows 2-13
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank that is cut exactly as
the ignition key that operates the
system.
To program the new key:
1. Verify the new key has
1
stamped on it.
2. Insert the original, already programmed key into the ignition
lock cylinder and start the
engine. If the engine will not
start, see your dealer for service.
3. After the engine has started, turn the key to LOCK/OFF and
remove the key. 4. Insert the key to be programmed
and turn it to ON/RUN within
10 seconds of removing the
previous key.
The security message will turn
off once the key has been
programmed. It may not be
apparent that the security
message went on due to how
quickly the key is programmed.
5. Repeat Steps 1 through 4 if additional keys are to be
programmed. If you lose or damage a
PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to have a new
key made.
Do not leave the key or device
that disarms or deactivates the
theft-deterrent system in
the vehicle.
