Arming the system
When armed, the perimeter alarm will notify you of an unauthorized
entry. When unauthorized entry occurs, the system will flash the park
lamps and will sound the horn.
The system is ready to arm whenever the key is out of the ignition. Any
of the following actions will arm the alarm system:
•Press the remote transmitter lock control one time to arm the system.
•Lock all doors using the keypad.
•Lock all doors using the interior power lock switch while the driver or
passenger door is open and then closed.
If all the closures (doors, trunk, hood) are closed, the park lamps will
flash once and the horn will chirp once when the
on the remote
entry transmitter is pressed a second time within five seconds.
If any closure is not properly closed, the park lamps will not flash and
the horn will chirp twice.
The system will wait 20 seconds after one of the arming actions is
performed before allowing the alarm to become armed. After the
20–second pre-arm phase, the interior trim remote trunk release control
and the power door unlock control are disabled, in order to further
protect your vehicle.

•Unlock the doors by using the remote entry transmitter.
•Unlock the doors using a valid code on the keypad.
