passenger door, side door, rear door, or the
hood is opened without first disarming the
system. When the alarm is activated, the
turn signals flash and the horn sounds for

then re-arm to monitor for the next

not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
IfKis pressed and the horn chirps and the
lights flash three times, the alarm was
activated while the alarm system was
armed.
If the alarm system has been activated, and
allowed to complete an event
(approximately one minute), a message will
appear on the Driver Information Center
(DIC) the next time the vehicle is started.

Keys, Doors, and Windows 17
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.
If the engine does not start and the security
light 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. 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.
It is possible for the PASS-Key III+ decoder to
learn the transponder value of a new or
replacement key. Up to eight 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 alocksmith who can service PASS-Key III+ to
have keys made and programmed to the
system.
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
1stamped
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 ignition off and remove the key.
4. Insert the key to be programmed and turn the ignition on within 10 seconds of
removing the previous key.
The security light will turn off once the
key has been programmed. It may not
be apparent that the security light went
on due to how quickly the key is
programmed.
5. Repeat Steps 1–4 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.Exterior Mirrors
