We’ve all been there: driving down a poorly-lit road, you activate the car’s high beams for better visibility of what’s ahead. Miles later, you realize that you’re the idiot with high-beams still on, blinding everyone and everything in sight. GM’s IntelliBeam system to the rescue.
Available on all Cadillacs on sale today, IntelliBeam automatically turns the vehicle’s high-beam headlamps on and off according to surrounding traffic conditions. The concept behind IntelliBeam is relatively simple: the system turns the high-beam headlamps on when it is dark enough and there is no other traffic present, and then turns them off when conditions change.
To enable the automatic IntelliBeam system, place the turn signal lever in the neutral position, then turn the exterior lamp control to AUTO. The blue high-beam on light will appear on the instrument cluster when the high beams are on.
Driving with IntelliBeam
The system only activates the high beams when driving over 40 km/h (25 mph). The system works via a sensor located at the top center of the windshield, which automatically controls the system. As such, keeping this area of the windshield clear of debris to allow for best system performance.
Under automatic control, the high-beam headlamps remain on until one of the following situations
- 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 20 km/h (12 mph)
- The turn signal lever is moved forward to the high-beam position or the Flash-to-Pass feature is used
The IntelliBeam system can be disabled by the High/Low-Beam Changer or the Flash-to-Pass feature. If this happens, the High/Low-Beam Changer must be activated two times within five seconds to reactivate the IntelliBeam system. The instrument cluster light will come on to indicate the IntelliBeam is reactivated.
The high beams may not turn off automatically if the system cannot detect other vehicle’s lamps because of any of the following:
- The other vehicle’s lamps are missing, damaged, obstructed from view, or otherwise undetected
- The other vehicle’s lamp 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 light sensor
- Your vehicle’s windshield is covered with ice, dirt, haze, or other obstructions
- Your vehicle is loaded such that the front end points upward, causing the light sensor to aim high and not detect headlamps and taillamps
- You are driving on winding or hilly roads
If any of the above conditions exist, you may need to manually disable or cancel the high-beam headlamps by turning the low-beam headlamps on.
