Driving with IntelliBeam IntelliBeam only activates the high-beams when driving over 20 mph (32 km/h). The high-beam headlamps remain on, under the automatic control of IntelliBeam, until any of the following situations occur: . . 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. The system detects an approaching vehicle's headlamps. The system detects a preceding vehicle's taillamps. The outside light is bright enough that high-beam headlamps are not required. The vehicle's speed drops below 15 mph (24 km/h). The headlamp stalk is moved forward to the high-beam position or the flash-to-pass feature is used. See Headlamp High/Low-Beam Changer on page 4 ‑ 6 and Flash-to-Pass on page 4 ‑ 10 . When either of these conditions occur, the IntelliBeam feature is disabled and the IntelliBeam light in the mirror turns off until the high-beam stalk is returned to the neutral position. . 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. 4-25 . . . . . . . . If IntelliBeam was using low-beams prior to this action, the IntelliBeam feature is temporarily disabled until the stalk is returned to the neutral position. .
