GMC 2007 Automobile User Manual


 
Disarming the System
To disarm the system, do one of the following:
Unlock the driver’s or passenger’s front
door using the key.
Press the unlock button on the remote keyless
entry transmitter.
The LED light on the transmitter will
flash once.
All of the doors will unlock.
The hazard warning lamps will
flash twice.
If the door is not opened or if the engine is not
started within 30 seconds after disarming the
system using the transmitter, all of the doors will
automatically lock and the theft-deterrent mode will
rearm.
How the System Alarm is Activated
If a door or the trunk or liftgate is opened without
using the key or the remote keyless entry
transmitter, the horn will sound and the lamps will
flash for up to 30 seconds.
How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated
using one of the following methods:
Press the lock or unlock buttons on the
remote keyless entry transmitter.
Unlock the driver’s or passenger’s front door
using the key.
Otherwise, the alarm will automatically stop after
30 seconds. The system will then lock the
doors and rearm the theft-deterrent system.
How to Detect a Tamper Condition
If the hazard warning lamps flash once when you
press the lock or unlock buttons on the remote
keyless entry transmitter, the theft-deterrent
system alarm was activated while you were away.
