• The exterior lamp control is turned to any setting except AUTO. When this occurs, IntelliBeam™ is disabled until the control is turned back to the AUTO position. • The IntelliBeam™ system is turned off at the inside rearview mirror. IntelliBeam™ might not turn off the high-beams if the system cannot detect other vehicle's lamps because of any of the following: • The other vehicle's lamp(s) are missing, damaged, obstructed from view, or otherwise undetected. • The other vehicle's lamp(s) are covered with dirt, snow, and/or road spray. • The other vehicle's lamp(s) cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions. • Your vehicle's windshield is dirty, cracked, or obstructed by something that blocks the view of the IntelliBeam™ light sensor. • Your vehicle's windshield is covered with ice, dirt, haze, or other obstructions. • Your vehicle is loaded such that the front end of the vehicle points upward, causing the IntelliBeam™ sensor to aim high and not detect headlamps and taillamps. • You are driving on winding or hilly roads. You might need to manually disable or cancel the high-beam headlamps by turning the low-beam headlamps on, if any of the above conditions exist.
