Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
the vehicle impossible to steal.
Vehicle Alarm System
This vehicle has an anti-theft alarm
system.
The indicator light, on the instrument
panel near the windshield, indicates
the status of the system.
Off :Alarm system is disarmed.
On Solid : Vehicle is secured during
the delay to arm the system. Fast Flash :
Vehicle is unsecured.
A door, the hood, or the trunk is open.
Slow Flash : Alarm system is armed.
Arming the Alarm System
1. Close the trunk and the hood.
Turn off the vehicle.
2. Lock the vehicle in one of three ways:
.Use the RKE transmitter.
. Use the Keyless Access
system.
. With a door open, press the
inside
Q.
3. After 30 seconds the alarm system will arm, and the
indicator light will begin to
slowly flash indicating the alarm
system is operating. Pressing
Q
on the RKE transmitter a second
time will bypass the 30-second
delay and immediately arm the
alarm system.
The vehicle alarm system will not arm
if the doors are locked with the key. If the driver door is opened without
first unlocking with the RKE
transmitter, the horn will chirp and
the lights will flash to indicate
pre-alarm. If the vehicle is not started,
or the door is not unlocked by
pressing
Kon the RKE transmitter
during the 10–second pre-alarm, the
alarm will be activated.
The alarm will also be activated if a
passenger door, the trunk, or the hood
is opened without first disarming the
system. When the alarm is activated,
the turn signals flash and the horn
sounds for about 30 seconds. The
alarm system will then re-arm to
monitor for the next unauthorized
event.
Disarming the Alarm System
To disarm the alarm system or turn
off the alarm if it has been activated:
. Press
Kon the RKE transmitter.
. Unlock the vehicle using the
Keyless Access system.

40 KEYS, DOORS, AND WINDOWS
To avoid setting off the alarm by
accident:
.Lock the vehicle after all
occupants have left the vehicle
and all doors are closed.
. Always unlock a door with the
RKE transmitter or use the Keyless
Access system.
Unlocking the driver door with the key
will 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, a message will appear on
the DIC. See Security Messages 0141.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed. The vehicle is automatically
immobilized when the vehicle is
turned off.
The immobilization system is
disarmed when the pushbutton start
is activated to enter the ACC/
ACCESSORY mode or the ON/RUN/
START mode and a valid transmitter
is present in the vehicle.
The security light in the instrument
cluster comes on if there is a problem
with arming or disarming the
theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, ON/RUN/
START, OFF), and the RKE transmitter
appears to be undamaged, try another
transmitter. Or, you may try placing
the transmitter in the transmitter
pocket in the center console. See
Key
and Lock Messages 0137.
If the ignition modes will not change
with the other transmitter, your
vehicle needs service. If the ignition
does change modes, the first
transmitter may be faulty. See your
dealer who can service the
theft-deterrent system and have a new
RKE transmitter programmed to the
vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
