Locks and Security
Triggering the anti-theft system
The armed system will be triggered if any door, liftgate or the hood is
opened without using the key, the keypad or the remote entry
transmitter.
To deactivate the triggered alarm state:
• Unlock the doors by pressing the
transmitter.
• Unlock the doors with a key. Turn the key full travel (toward the front
of the vehicle) to ensure the alarm disarms.
• Unlock the doors using the keypad.
• Press
on the remote entry transmitter to disable the alarm; the
alarm will be disabled, but the vehicle will remain in an armed state.
• Turning the key in the ignition to the 3 (RUN) or 4 (START) position.
Note: The key must be a valid, programmed, coded key.
