150 LIGHTING
: Turns on the headlamps together
with the parking lamps and
instrument panel lights.
®
IntelliBeam System
If equipped, this system turns the
vehicle's main beam headlamps on
and off according to surrounding
traffic conditions.
The system turns the main 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,
with the indicator lever in the neutral
position, turn the exterior lamp
control to AUTO. The blue main beam
on light appears on the instrument
cluster when the main beams are on.
Driving with IntelliBeam
The system only activates the main
beams when driving over 40 km/h
(25 mph).
There is a sensor near the top centre
of the windscreen, which
automatically controls the system.
Keep this area of the windscreen clear
of debris to allow for best system
performance.
The main 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 tail lamps.
The outside light is bright enough
that main beam headlamps are
not required.
The vehicle's speed drops below
20 km/h (12 mph).
The Intellibeam system is 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 system is reactivated.
See Headlamp Main/Dipped-Beam
Changer 0 151 and Flash-to-Pass
0 151.
The main beams may not turn off
automatically if the system cannot
detect other vehicle's lamps because
of any of the following:
The other 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.
