2009 Cadillac STS-V Owner's Manual - Page 188

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 control of IntelliBeam, until any of the following situations occur: • 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 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 its starting position. If either of these conditions occur and IntelliBeam already has the high-beam headlamps on, the feature is disabled and the 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. 3-34 • The IntelliBeam system is turned off at the inside rearview mirror. • 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.
