The high-beam headlamps remain on, under the control of IntelliBeam™, until any of the following situations occur: • The IntelliBeam™ system is turned off at the inside rearview mirror. • The system detects an approaching vehicle's headlamps. • The vehicle's speed drops below 15 mph (24 km/h). IntelliBeam™ may not turn off the high-beams if the system cannot detect other vehicle's lamps because of any of the following: • The others 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. 3-35 • The system detects a preceding vehicle's taillamps. • The outside light is bright enough that high-beam headlamps are not required. • The high-beam headlamps are manually turned on or you use the flash-to-pass feature. See Headlamp High/Low-Beam Changer on page 3-9 and Flash-to-Pass on page 3-13. When either of these conditions occur, the IntelliBeam™ feature is temporarily disabled until the high-beam stalk is returned to the neutral position. If either of these conditions occur and IntelliBeam™ already has the high-beam headlamps on, the IntelliBeam™ feature is disabled and the IntelliBeam™ light in the mirror turns off. • 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 and the AUTOMATIC LIGHTS ON message displays on the DIC.
