If a door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. Your
vehicle?s lamps will ?ash and the horn will sound
for 30 seconds. The lamps and horn will then turn off to
save battery power.
Remember, the theft-deterrent system won?t activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct key if the
alarm has been set off.
Here?s 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 a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm.
If you set off the alarm by accident, unlock any door
with your key. You can also turn off the alarm by
pressing the unlock button on the remote keyless entry
transmitter. The alarm won?t stop if you try to unlock
a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down the driver?s
window and open the driver?s door.
2. Activate the system by locking the doors using the
power door lock switch while the door is open, or
using the remote keyless entry transmitter.
3. Get out of the car, 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 lamps ?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 5-92.
If the alarm does not sound or the vehicle?s lamps do
not ?ash, the vehicle should be serviced by a GM dealer.
