Your vehicle has a content theft-deterrent alarm system.

The remote keyless entry transmitter is used to arm/disarm the content theft-deterrent system. See Remote Keyless Entry (RKE) System Operation . Your vehicle's theft-deterrent system can be programmed to three different modes.

Active Arming: The system will arm when the lock button on the remote keyless entry transmitter is pressed. The security system light will come on steady for thirty seconds. During this time you can still get back into the vehicle without triggering the alarm. Once the light starts flashing the system is armed. The system will disarm when the unlock button on the transmitter is pressed.

Passive Arming: The system will arm itself one minute after the ignition is turned off and the driver's door has been opened and closed. If the lock button on the transmitter is pressed before the minute has passed, the system will arm immediately. The system will disarm when the unlock button is pressed.

Security System Disable: The system will not arm.

Content Theft-Deterrent Personalization

To change the mode that your vehicle is programmed to, do the following:

  1. Turn the ignition to RUN or ACC (Accessory).
  2. Press the panic alarm button on the transmitter slowly four times within five seconds.
  3. You must complete one of the following within three seconds to change the mode.
  4. • To select the active arming mode, press the lock button on the transmitter once within three seconds. A chime will sound two times to acknowledge that the active arming mode has been selected.
    • To select the passive arming mode, press the lock button on the transmitter twice within three seconds. A chime will sound three times to acknowledge that the passive arming mode has been selected.
    • To select the security system disable mode, press the unlock button on the transmitter once within three seconds. A chime will sound one time to acknowledge that the security system disabled mode has been selected.

If you accidentally set off the alarm when entering or exiting the vehicle, you can shut it off by pressing either the lock or unlock button once on the remote keyless entry transmitter. The panic alarm button needs to be pressed twice to turn off the alarm. There is a ten second pre-alarm grace period indicated by a rapid beeping. By pressing the transmitter buttons as indicated above, you can disarm the system before the horn begins to sound and the exterior lights begin to flash.

If you hear three horn chirps when you press the unlock button on the transmitter, that means the vehicle's alarm was triggered while you were away.
