a 10 second pre-alarm will occur.
The horn will chirp and the lights
will flash. If the key is not placed
in the ignition and turned to START
or the door is not unlocked by
pressing the unlock button on
the RKE transmitter during the
10 second pre-alarm, the alarm
will go off. The vehicle's headlamps
will flash and the horn will sound
for about 30 seconds, then will turn
off to save the battery power.
The theft-deterrent system will not
activate if the doors are locked with
the key or the manual door lock.
It activates only if you use the
power door lock switch or the RKE
transmitter. The vehicle can be
started with the correct key if the
alarm is set off.To avoid setting off the alarm by
accident:
.If you do not want to activate
the theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock a door with the
RKE transmitter.
If the alarm is set off, press unlock
on the RKE transmitter or place the
key in the ignition and turn it to
START.
Testing the Alarm
To test the alarm:
1. Lower the driver window and open the driver door.
2. Press lock on the RKE transmitter. 3. Close the door and wait for the
security light to go out.
4. Reach in through the window, unlock the door with the manual
door lock, and open the door.
This should set off the alarm.
If the alarm does not sound when
it should but the headlamps flash,
check to see if the horn works. The
horn fuse may be blown. To replace
the fuse, see Fuses and Circuit
Breakers on page 10‑48.
If the alarm does not sound or the
headlamps do not flash, see your
dealer for service.

Immobilizer Operation
This vehicle has 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.
The system is automatically
disarmed when the key is turned
to ON/RUN, ACC/ACCESSORY
or START from the LOCK/OFF
position. 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 prevents the vehicle
from starting. 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 light on the instrument
panel cluster comes on when trying
to start the vehicle, there may be
a problem with the theft-deterrent
system. 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 fuse. See
Fuses and
Circuit Breakers
on page 10‑48.
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 who can service
the PASS-Key
®III+ to have a new
key made. In an emergency, contact
Roadside Assistance.
It is possible for the PASS-Key
®III+
decoder to learn the transponder
value of a new or replacement key.
