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.
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, see
Fuses and Circuit Breakers on page 5-85.
If the alarm does not sound or the vehicle's headlamps
do not ¯ash, the vehicle should be serviced by an
authorized service center.
Passlockž
Your vehicle is equipped with the
Passlockžtheft-deterrent system.
Passlock
žis a passive theft-deterrent system.
Passlockženables 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, fuel is disabled.
During normal operation, the SECURITY light will
go off approximately ®ve seconds after the key is turned
to RUN.
If the engine stalls and the SECURITY light ¯ashes,
wait about 10 minutes until the light stops ¯ashing 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 message
comes on, you will be able to restart the engine if
you turn the engine off. However, your
Passlock
žsystem is not working properly and must be
serviced by your dealer. Your vehicle is not protected
by Passlock
žat this time. You may also want to check
the fuse. SeeFuses and Circuit Breakers on page 5-85.
See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-6.
