GMC 2005 Canyon - Manual (Page 97)

If a locked door is not opened using the remote keyless
entry transmitter, or by OnStar
® , the alarm will go off.
The front turn signal lamps will flash for two minutes,
and the horn will sound for two minutes, then will turn off
to save the battery power.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key, the manual door lock,
or power door lock switch. The system can only
be activated using the remote keyless entry transmitter,
or by OnStar
® . You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
• If you don’t 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 remote keyless entry
transmitter. Unlocking a door any other way will set
off the alarm.
If you set off the alarm by accident, you can turn off the
alarm by pressing unlock 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, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
3. To turn the alarm off, press the unlock button
on the remote keyless entry transmitter or start
the engine.
If the alarm does not sound when it should but the lights
flash, check to see if the horn works. The horn fuse
may be blown. To replace the fuse, see Fuses
and Circuit Breakers on page 5-99.
If the alarm does not sound or the headlamps do not
flash, see your dealer for service.
