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. IntelliBeam might not turn off the high-beams if the system cannot detect other vehicle's lamps because of any of the following: • 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 other vehicle's lamp(s) are missing, damaged, obstructed from view, or otherwise undetected. • 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. • 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. • 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. 4-27
