The security light will turn on to indicate that
arming has been initiated. Once the system is
armed, the security light will flash once every
three seconds.
If the security light is flashing twice per second,
this means that a door is open.
If you do not want to arm the system, you may
lock the car with the manual lock knobs on
the doors.

You can disarm the system by doing any one of
the following:
•
Press the remote keyless entry transmitter
unlock button.
•

Once the system is disarmed, the security light will
stop flashing.

How the System Alarm is Activated
If the system is armed, it can be activated
by either:
•
Opening the driver's door or tailgate. This will
cause a ten second pre-alarm chirp followed
by a thirty second full alarm of horn and lights.
•
Opening any other door. This will immediately
cause a full alarm of horn and lights for
thirty seconds.
When an alarm event has finished, the system will
re-arm itself automatically.
How to Turn Off the System Alarm
To turn off the system alarm, do one of the
following:
•
Press the lock button on the remote keyless
entry transmitter. The system will then
re-arm itself.
•
Press the unlock button on the remote keyless
entry transmitter. This will also disarm the
system.
•
Insert the key in the ignition and turn it on.
This will also disarm the system.
