HUMMER H3 2007 Owners Manual

Battery Replacement
Under normal use, the battery in the remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter
will not work at the normal range in any location.
If you have to get close to your vehicle before
the transmitter works, it is probably time to change
the battery.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.To replace the battery, do the following:
1. Insert a coin, or similar object, in the slot
between the covers of the transmitter
housing. Gently pry the transmitter apart.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

Programmable Automatic
Door Locks
If your vehicle has an automatic transmission, it is
programmed from the factory to lock the doors
automatically when the shift lever is moved out of
PARK (P). All the doors will unlock when the
shift lever is moved back into PARK (P).
If your vehicle has a manual transmission, it is
programmed from the factory to lock the
doors automatically when the vehicle speed is
greater than 15 mph (24 km/h). The doors
will unlock when the key is removed from the
ignition.
To personalize the automatic door locks, see
“Automatic Door Locks” underDIC Controls and

Theft-Deterrent Systems
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put on it can make it impossible to steal.
Content Theft-Deterrent
Your vehicle has a
content theft-deterrent
alarm system.To activate the content theft-deterrent system, do
the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
If the lock button on the remote keyless entry
transmitter is pressed, but a door is open,
the doors will lock, the lights may ash and the
horn may sound. Close the open door and
the alarm system will arm.
If a locked door is not opened using the remote
keyless entry transmitter, or by OnStar
®, the alarm
will go off. First, a pre-alarm will sound the horn
at reduced intensity for 10 seconds. Then, the front
turn signal lamps will ash for two minutes, and
the horn will sound for two minutes. The alarm will
then turn off to save battery power.
Starting the engine with the correct key will shut
off the pre-alarm or alarm at any time.
Remember, the theft-deterrent system will not
activate if you lock the doors with the key,
the manual door lock, or power door lock switch.
98

The system can only be activated using the
remote keyless entry transmitter, or by OnStar®.
SeeOnStar®System on page 129for 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 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 417.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer for service.
99

Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned 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 will not start.
During normal operation, the security light will turn
off approximately ve seconds after the engine
is started. SeeSecurity Light on page 190.
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 light
comes on, you will be able to restart the engine if
you turn the engine off. However, your Passlock
®
system is not working properly and must be
serviced by your dealer. Your vehicle is not
protected by Passlock
®at this time. See your
dealer for service.
In an emergency, call the Roadside Assistance
Center. SeeRoadside Assistance Program
on page 454.
