For 1990-2009 cars only

Your vehicle is equipped with a battery saver feature designed to protect your vehicle's battery.

When any interior lamp (trunk, reading, dome, etc.) is left on and the ignition is turned off, the battery rundown protection system will automatically turn the lamp off after 20 minutes. This will avoid draining the battery. This system does not protect against leaving on the headlamps or parking lamps.

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

    • Turn the ignition on.
    • Turn the activated interior lamp off, then on.
    • Open any door.

The battery rundown protection feature will also be activated when any door is left open.
