Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Anti-Theft Alarm System
This vehicle may have a content
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 Remote
Keyless Entry (RKE) transmitter.
The security light should flash.
If the delayed locking feature is
active, the alarm will not be
activated until all doors are
closed and the security light
goes off.
3. Close all doors. The security
light will stop flashing and go off
after approximately 30 seconds.
The system is armed when 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. The
vehicle's headlamps will flash and
the horn will sound for about
30 seconds, then will turn off to save
the battery power.
