Hummer 2007 H3 - Manual (Page 99)

The system can only be activated using the
remote keyless entry transmitter, or by OnStar
® .
See OnStar ® System on page 129 for additional
information. You should also remember that
you can start your vehicle with the correct 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 arm the theft-deterrent
system, the vehicle should be locked with
the manual door lock lever, the power
door lock switch, or the key, after the doors
are closed.
• If the content theft-deterrent system is armed,
unlock the doors by pressing the unlock
button on the remote keyless entry transmitter
or by OnStar
® . Unlocking a door any other
way will activate the alarm.
If you set off the alarm by accident, you can turn it
off by pressing unlock on the remote keyless
entry transmitter, starting the vehicle with
the correct key, or by having OnStar
® unlock the
doors. The alarm will not 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
pre-alarm. Wait 10 seconds for the full alarm
to activate.
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 417.
If the alarm does not sound or the front turn signal
lamps do not flash, see your dealer for service.
