IntelliBeam® System

If equipped, this system turns the vehicle's high-beam headlamps on and off according to surrounding traffic conditions.

The system turns the high-beam headlamps on when it is dark enough and there is no other traffic present.

This light comes on in the instrument cluster when the IntelliBeam system is enabled.

Turning On and Enabling IntelliBeam

To enable the IntelliBeam system, press on the turn signal lever when it is dark outside and the exterior lamp control is in AUTO or . The blue high-beam on light appears 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).

There is a sensor near the top center of the windshield that automatically controls the system.

Keep this area of the windshield clear of debris to allow for best system performance.

The high-beam headlamps remain on, under the automatic control, until one of the following situations occurs:

• 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 IntelliBeam system is disabled by the button on the turn signal lever. If this happens, press on the turn signal lever when the exterior lamp control is in the AUTO or position to reactivate the IntelliBeam system. The instrument cluster light will come on to indicate the IntelliBeam system is reactivated.
• The IntelliBeam system will turn off if the fog lamps are turned on.

The high beams may not turn off automatically if the system cannot detect another 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 lamps are covered with dirt, snow, and/or road spray.
• The other vehicle's lamps cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions.
• The vehicle's windshield is dirty, cracked, or obstructed by something that blocks the view of the light sensor.
• The vehicle is loaded such that the front end points upward, causing the light sensor to aim high and not detect headlamps and taillamps.
• The vehicle is being driven on winding or hilly roads.

The IntelliBeam system may need to be disabled if any of the above conditions exist.
