Inadvertent Power Battery Saver

This feature is designed to protect your vehicle’s battery against drainage from the interior lamps, or garage door opener. When the ignition is turned off, the power to these features will automatically turn off after 10 minutes. Power will be restored for an additional 10 minutes if any door is opened, the trunk is opened or the courtesy lamp switch is turned on.
