Your vehicle may have a theft-deterrent alarm system.
A light located on top of your instrument panel (near the center of the vehicle, next to the windshield) will flash slowly to let you know that the system has been armed.
While armed, the doors will not unlock with the power door lock switch.
Once armed, the alarm will go off if someone tries to enter the vehicle without the optional remote keyless entry transmitter or the key or tries to turn the ignition on without using the correct key. The horn will sound and the headlamps and parking lamps will flash any time the alarm sounds.
To open the liftgate while armed, press the liftgate release button, located on the instrument panel switchbank, or press REAR on the remote keyless entry transmitter.
Your alarm system will arm when you use either power door lock switch to lock the doors while any door or the liftgate is open and the key is removed from the ignition. The security light will start flashing to let you know the system is armed.
Your alarm system will arm after a 30 second delay when you press LOCK on your remote keyless entry transmitter to lock the doors. The security light will come on for 30 seconds and then start flashing to let you know the system is armed.
Your alarm system will disarm when you use your key to unlock the front doors. The security light will stop flashing to let you know the system is no longer armed.
Your alarm system will disarm when you press UNLOCK on your remote keyless entry transmitter to unlock the doors. The security light will stop flashing to let you know the system in no longer armed.
