Lighting
The system turns the high-beam headlamps
on when it is dark enough and there is no
other traffic present.
This light comes on in the instrument
cluster when the IntelliBeam system is
enabled.
Turning On and Enabling IntelliBeam
To enable the IntelliBeam system, activate
the high/low-beam changer two times
within two seconds while the exterior lamp
control is in AUTO or
2
.
Driving with IntelliBeam
The system only activates the high beams
when driving over 40 km/h (25 mph).
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.
.
The vehicle's speed drops below 20 km/h
(12 mph).
.
The IntelliBeam system can be disabled
by the High/Low-Beam Changer or the
Flash-to-Pass feature. If this happens, the
High/Low-Beam Changer must be
activated two times within two seconds
to reactivate the IntelliBeam system.
The instrument cluster light will come
on to indicate the IntelliBeam is
reactivated. See
and
.
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.
.
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.
