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

power door lock switch while the door is open, or
with the remote keyless entry 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.

While the alarm is set, the power door unlock switch is
not operational.

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
Instrument Panel Fuse Block on page 5-106 and
Underhood Fuse Block on page 5-109.

If the alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your dealer.

Passlock

®

Your vehicle is equipped with the Passlock

®

theft-deterrent system.

Passlock

®

is a passive theft-deterrent system. Passlock

®

enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, the fuel system is
disabled and the vehicle will not start.

During normal operation, the security light will turn off
approximately five seconds after the key is turned
to RUN.

If the engine stalls and the security light flashes, wait
about 10 minutes until the light stops flashing before
trying to restart the engine. Remember to release
the key from START as soon as the engine starts.

If the engine does not start after three tries, the vehicle
needs service.

If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock

®

system is

not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock

®

at this

time. You may also want to check the fuse. See
Fuses and Circuit Breakers on page 5-105. See your
dealer for service.

In an emergency, call the Roadside Assistance Center.
See Roadside Assistance Program on page 7-6.
