After 30 seconds the alarm system will arm,
and the indicator light will begin to slowly

operating. Pressing Q on the remote key
asecond time will bypass the 30-second
delay and immediately arm the alarm
system.
The vehicle alarm system will not arm if the
doors are locked with the key.
If the driver door is opened without first
unlocking with the remote key, the horn will
chirp and the lights will flash to indicate pre-
alarm. If the vehicle is not started, or the door
is not unlocked by pressing K on the remote
key during the 10-second pre-alarm, the alarm
will be activated.
The alarm will also be activated if apassenger
door, the liftgate, or the hood is opened
without first disarming the system. When the
alarm is activated, the turn signals flash and the
horn sounds for about 30 seconds. The alarm
system will then re-arm to monitor for the next
unauthorized event.
