Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned to LOCK/OFF and a door has been opened. This protects against draining the battery if the headlamps or parking lamps are accidentally left on. If you need to leave the lamps on for more than 10 minutes, use the exterior lamp control to turn the lamps back on after the ignition is turned to LOCK/OFF and any door is opened.
