Chevrolet Optra 2005 Owner's Manual page 87

To avoid activating the alarm by accident, use one of
the following methods:
•
Unlock the driver's or passenger's door using
the key.
•
Press the unlock button on the remote keyless
entry transmitter.
Unlocking a door any other way will activate the alarm
when a door, the trunk or liftgate is opened.
If you do not want to arm the theft-deterrent system,
lock the vehicle using the key or the manual door locks.
Disarming the System
To disarm the system, use one of the following methods:
•
Unlock the driver's or passenger's door using
the key.
•
Press the unlock button on the transmitter.
− The LED light on the transmitter will
flash once.
− All of the doors will unlock.
− The hazard warning lamps will flash twice.
− The theft-deterrent mode will deactivate.
If the door is not opened or if the engine is not started
within 30 seconds after disarming the system with
the transmitter, all of the doors will automatically lock
and the theft-deterrent mode will reactivate.
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 button 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
reactivate 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, that means the theft-deterrent system
alarm was triggered while you were away, from the
vehicle.
