Exterior Lamps Off Reminder; Headlamp High/Low-Beam; Changer - GMC Cadillac XT4 2019 Owner's Manual

156 LIGHTING
To enable the IntelliBeam system,
press the button on the end of the
turn signal lever when the exterior
lamp control is in the AUTO or
position. 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 the
button on the end of the turn
signal lever when the exterior
lamp control is in the AUTO or
position. The instrument cluster
light will come on to indicate the
IntelliBeam is reactivated.
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.
Driving on winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.
