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.
•
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.
