What to Do Right Now

Turn off all non-essential electrical loads (AC, heated seats, audio system). Drive directly to the nearest repair shop — you have approximately 30-60 minutes of driving before the battery is depleted and the engine stalls. If the A/C or infotainment system starts behaving erratically, the battery is critically low — pull over and call for a tow. The Aviator's electrical system is complex due to the 48V mild hybrid system, so diagnosis should be done by a Lincoln-certified technician.
