The delayed lighting feature will continue to illuminate the interior for 25 seconds after all doors have been closed, so that you can find your ignition and buckle your safety belt at night. Delayed lighting will not occur while the ignition is in RUN or ACCESSORY. After 25 seconds have passed, the interior lamps will slowly fade out. The lamps will fade out before the 25 seconds have passed if you do one of the following:

    • Turn the ignition to RUN or ACCESSORY.
    • Lock all doors using the remote keyless entry transmitter.
    • Lock all doors using the power door lock switch or the key.

To turn the delayed lighting feature off or on, see Vehicle Personalization .
