If a locked door is opened without using the key in the
driver’s door key cylinder or 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 the doors
are locked with the vehicle’s key or the manual door
lock. It activates only if you use the power door
lock switch with the door open or 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.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
To test the alarm:
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 5-100.
If the alarm does not sound or the vehicle’s headlamps
do not ash, see your dealer/retailer for service.

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, seeFuses
and Circuit Breakers on page 5-100. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer/retailer who can service the

loosen or thaw them. Damaged wiper blades may
not clear the windshield well, making it harder to see

install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-47.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
