IntelliBeam Intelligent High-Beam Headlamp Control System

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

IntelliBeam is an enhancement to your vehicles headlamp system. Using a digital light sensor on the rearview mirror, the system will turn the vehicles high beam headlamps ON and OFF according to surrounding traffic conditions. The IntelliBeam system will turn ON the high-beam headlamps when it is dark enough, there is no other traffic present, and the IntelliBeam system is enabled. When the conditions are met, the inside rearview mirror will send a GMLAN serial data message to the BCM requesting high beam headlamp operation.

Driving with IntelliBeam

IntelliBeam will only activate the high-beams when driving over 32 km/h (20 mph). The high beam headlamps will remain ON, under the automatic control of IntelliBeam, until any of the following situations occur:

The system detects an approaching vehicles headlamps.
The system detects a preceding vehicles tail lamps.
The outside light is bright enough that the high-beam headlamps are not required.
The vehicles speed drops below 24 km/h (15 mph).
The headlamp stalk is moved forward to the high-beam position or the flash-to-pass feature issued. See when either of these conditions occur, the IntelliBeam feature will be disabled and the IntelliBeam light in the mirror will turn OFF until the high-beam stalk is returned to the neutral position.
If IntelliBeam was using low-beams prior to this action, the IntelliBeam feature will be temporarily disabled until the stalk is returned to the neutral position.
The exterior lamp control is turned to any setting except AUTO. When this occurs, IntelliBeam will be disabled until the control is turned back to the AUTO position.
The IntelliBeam system is turned OFF at the inside rearview mirror.

The high beam headlamps may need to manually disabled or canceled by turning the low beam headlamps ON, if any of the above conditions exist.

IntelliBeam can be disabled by using the controls on the inside rearview mirror.
