This feature allows the driver to delay the locking of the vehicle. It will not operate with the key in the ignition. See Lockout Protection .

Press the driver power door lock switch or the Remote Keyless Entry (RKE) transmitter lock button once. With the key removed from the ignition and the driver door open, the following occurs:

    • Three chimes sound to signal the delay.
    • All doors will lock and the turn signals flash once five seconds after the last door has been closed.
    • The horn chirps if the horn chirp feature is enabled. See DIC Vehicle Personalization .

If a door is opened before the five seconds has elapsed, the doors do not lock until five seconds after all doors are closed.

If the power door lock switch or the transmitter lock button is pressed twice when leaving the vehicle, the doors lock immediately.

If the power door unlock switch or the transmitter unlock button is pressed, the doors unlock immediately and do not lock automatically after the doors are closed.

This feature is turned on at the factory but may be turned off through the Driver Information Center (DIC). See DIC Vehicle Personalization .
