Your vehicle has a battery run-down feature designed to protect your vehicle's battery.

When any interior lamp (trunk, reading lamps, dome lamp or glove box) is left on when the ignition is turned off, the battery run-down protection system will automatically shut the lamp off after 20 minutes. This will avoid draining the battery.

To reactivate the interior lamps, do one of the following:

    • Lift the driver's door handle,
    • open any door or
    • press any remote keyless entry transmitter button,
    • press the power door lock switch,
    • press the remote trunk release or
    • turn the lamp that was left on to off and then to on again.
