Theft-Deterrent Systems
This vehicle has theft-deterrent features, however, they
do not make it impossible to steal.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.

illuminated for 30 seconds. After the security light
goes off, the theft‐deterrent system is armed.
Pressing the lock button twice will arm the system
immediately. If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is
open or not closed completely, the security light
will flash for 60 seconds and then turn off. The
theft‐deterrent system is armed but the alarm will
not sound if the trunk lid, hood or door that was not
closed completely is tampered with or opened. The
alarm will sound for the trunk lid, hood or a door
that was completely closed at the time the vehicle
was locked using the keyless access transmitter.
.Exit the vehicle and lock the door with the power
door lock switch or lock button on the keyless
access transmitter. The security light should flash.
Close the door. The security light will stop flashing
and stay on. After 30 seconds the light should turn
off, the theft‐deterrent system is armed.
.If Passive Arming is activated through the vehicle
personalization feature, the system will arm
automatically after you close the door and take
at least one keyless access transmitter with you.
The security light will turn on. After 60 seconds the
light should turn off. The theft-deterrent system is
armed. See
Vehicle Personalization
on page 3‑59.

If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will flash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
The Theft-Deterrent system will not arm if :
.The key is used to turn the key cylinder to the lock
position.
.The driver's door is locked using the power door
lock switch after the doors are closed.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft‐deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. See Vehicle Personalization
on
page 3‑59.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver's door
disarms the theft-deterrent system. Unlocking a door
any other way while the system is armed will activate
the alarm.
Testing the Alarm
1. From inside the vehicle, roll down the window, then get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock the vehicle using the power door lock switch
or the keyless access transmitter and close the
door. Wait about 30 seconds until the security light
goes off.
3. Reach in and open the door using the inside door handle. The horn will sound and the exterior lamps
will flash.
You can turn off the alarm by pressing the unlock button
on the keyless access transmitter or by starting the car.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers
on
page 6‑115. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
Theft-Deterrent system when leaving your vehicle.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, place the transmitter in
the transmitter pocket. See“NO FOBS DETECTED”
under DIC Warnings and Messages
on page 4‑76for
additional information. Check the fuse. See Fuses and
Circuit Breakers
on page 6‑115. If the engine still does
not start with the other transmitter, the vehicle needs
service. If the engine does start, the first transmitter
may be faulty. See your dealer or have a new keyless
access transmitter programmed to the vehicle.
The immobilizer system can learn new or replacement
keyless access transmitters. Up to four keyless access
transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 3‑5.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice: The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
.Do not drive at any one constant speed,
fast or slow, for the first 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake or slow the vehicle.
.Avoid making hard stops for the first
200 miles (322 km) or so. During this time the
new brake linings are not yet broken in. Hard
stops with new linings can mean premature
wear and earlier replacement. Follow this
breaking-in guideline every time you get new
brake linings.
.Do not tow a trailer during break-in. See
Towing a Trailer
on page 5‑31for the trailer
towing capabilities of your vehicle and more
information.
Following break‐in, engine speed and load can be
gradually increased.
