L(Vehicle Locator/Panic Alarm):Press and
release this button to locate your vehicle. The turn
signal lamps will ash and the horn will sound
three times. Press and hold this button for more
than two seconds to activate the panic alarm. The
turn signal lamps will ash and the horn will

turn off when the ignition is moved to RUN or
the alarm button is pressed again. The ignition
must be in OFF for the panic alarm to work.
Matching Transmitter(s) to Your
Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to
bring any additional transmitters so they can also
be re-coded to match the new transmitter.Once your dealer has coded the new transmitter,
the lost transmitter will not unlock your vehicle.
The vehicle can have a maximum of eight
transmitters matched to it. See “Relearn Remote
Key” underDIC Operation and Displays (With DIC
Buttons) on page 268orDIC Operation and
Displays (Without DIC Buttons) on page 275for
instructions on how to match RKE transmitters to
your vehicle.
Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about four years.
The battery is weak if the transmitter will not work
at the normal range in any location. If you have
to get close to your vehicle before the transmitter
works, it is probably time to change the battery.

Content Theft-Deterrent
Your vehicle may have a content theft-deterrent
alarm system.
To activate the theft-deterrent system, do the
following:
1. Open the door.
2. Lock the door with the Remote Keyless Entry
(RKE) transmitter. The security light should
come on and ash. The door does not need to
be open.
If the delayed locking feature is active, the
alarm will not be activated until all doors are
closed and the security light goes off.
3. Close all doors. The security light will stop
ashing and go off after approximately
30 seconds. The content theft deterrent alarm
is not armed until the security light goes off.If a door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The
horn will chirp and the lights will ash. 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 ten second pre-alarm, the alarm will go
off. Your vehicle’s headlamps will ash and the
horn will sound for about two minutes, then
will turn off to save the battery power.
The theft-deterrent system will not activate if you
lock the doors with a key, the manual door lock, or
the power door lock switch. It activates only if you
use the RKE transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
Here is how 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.
Unlocking a door any other way will set off the
alarm if the system has been armed.
128

If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE transmitter or
by placing the key in the ignition and turning it
to START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then 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 vehicle’s headlamps ash, check to see if the
horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers
on page 608.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for service.
