Cadillac 2008 STS, Owner'S Manual, Page: 189 / 500

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 the neutral
position. If either of these conditions occur and
IntelliBeam™ already has the high-beam headlamps
on, the IntelliBeam™ feature is disabled and the
IntelliBeam™ 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.
