Hummer 2010 H3 - Manual (Page 36)

2-10 Keys, Doors and Windows
To avoid setting off the alarm by
accident:
. Lock the vehicle with the manual
door lock lever, the power door
lock switch, or the key, after the
doors are closed.
. Unlock the doors by pressing
the unlock button on the RKE
transmitter or by contacting
OnStar. Unlocking a door any
other way activates the alarm.
Press unlock on the RKE
transmitter, start the vehicle with
the correct key, or have OnStar
unlock the doors to turn the alarm
off. The alarm does not stop if a
door is unlocked any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lock the
doors with the RKE transmitter.
2. Unlock the door with the manual
door lock and open the door.
The pre-alarm should sound
followed by the full alarm about
10 seconds later.
3. Press the unlock button on the
RKE transmitter or start the
engine to turn the alarm off.
If the alarm does not sound but the
lights flash, check to see if the horn
works. The horn fuse could be
blown. To replace the fuse, see
Fuses and Circuit Breakers on
page 10‑39.
If the alarm does not sound or the
front turn signal lamps do not flash,
see your dealer for service.

Operation (U.S.)
Passlock ® is a passive
theft-deterrent system that enables
fuel if the vehicle is started with a
valid key. If an incorrect key is used
or the ignition lock cylinder is
tampered with, the fuel system is
disabled and the vehicle does not
start.
The security light turns off
approximately five seconds after
the engine is started. See Security
Light on page 5‑17.
