The blue high-beam on light appears
on the instrument cluster when the
high beams are on.
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.

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.
.The vehicle is being driven on
winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.
