6-4 Lighting
The headlamp stalk is moved
forward to the high-beam
position.
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.
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 may need to manually disable
or cancel the high-beam headlamps
by turning the low-beam headlamps
on, if any of the above conditions
exist.
