IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entire
section before using it.
IntelliBeam is an enhancement to the vehicle's
headlamp system. Using a digital light sensor on the
rearview mirror, this system turns the vehicle's
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam system turns the high-beam headlamps
on when it is dark enough, there is no other traffic
present, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam button on the inside
rear view mirror. The IntelliBeam indicator on the
mirror turns on to indicate the system is on. Once the
system has been turned on, it remains on each time the
vehicle is started, but the IntelliBeam system must be
enabled.
To enable the IntelliBeam system, turn the exterior lamp
control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On Light
appears on the instrument panel cluster when the
high-beams are on. See Highbeam On Light on
page 4-61.
