WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
When a remote unlock is requested and the vehicle is off, doors locked, and a low ambient light is present, then the high beams, park lamps and backup lamps will come on for about 20 seconds or until a door is open, the key is turned to ACC or run, or a remote lock actuation.
