This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-theft Alarm System

theft-deterrent alarm system.
This is the security light.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the RemoteKeyless Entry (RKE) transmitter
or the power door lock switch. The security light will come on to
inform the driver the system is
arming. If a door is open when
the doors are locked, the
security light will flash.
If the delayed locking feature is
turned on, the theft‐deterrent
system will not start the arming
process until the last door is
closed and the delay timer has
expired. See
Delayed Locking
on page 2‑8.
3. Close all doors. The security light should go off after about
30 seconds. The alarm is not
armed until the security light
goes off.
If a locked driver door is opened
without using the RKE transmitter, a
10-second pre-alarm will occur. The
horn will chirp and the lights will
flash. If the key is not placed in the
ignition and turned to START or the
door is not unlocked by pressing
the unlock button on the RKE
transmitter during the 10-second
pre-alarm, the alarm will go off. Your vehicle's headlamps will flash
and the horn will sound for about
30 seconds, then will turn off to save
the battery power.
The theft-deterrent system will not
activate if the doors are locked with
the vehicle's key or the manual door
lock. It activates only if you use the
power door lock switch with the door
open or the RKE transmitter. You
should also remember that you can
start your vehicle with the correct
ignition key if the alarm has been
set off.

accident:.If you do not want to activate the
theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock the doors with the
RKE transmitter. Unlocking a
door any other way will set off
the alarm if it is armed.
