184 LIGHTING
Turning On and Enabling IntelliBeam
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
2
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 high/low-beam changer or
the flash-to-pass feature. If this
happens, press the button on the
end of the turn signal lever when
the exterior lamp control is in the
AUTO or
2position. The
instrument cluster light will come
on to indicate the IntelliBeam is
reactivated.
See Headlamp High/Low-Beam
Changer 0185 and Flash-to-Pass
0 185. 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.

2. High-Beam Headlamps
3. Night Vision System
By selecting a view on the instrument
cluster, the Night Vision image can be
displayed.
SeeInstrument Cluster (Base Level)
0 127 orInstrument Cluster (Uplevel)
0 130. The Night Vision system can
operate only if:
. The ignition is on.
. The vehicle is in P (Park) or a
forward gear.
. It is dark enough outside.
. The headlamps are on. Adjust the instrument panel
brightness to make the image no
brighter than necessary. Turn the
image off by selecting another view
on the instrument cluster.
Warm objects, such as pedestrians,
animals, and other moving vehicles,
should appear whiter on the Night
Vision display. Cold objects, such as
the sky, signs, and parked vehicles,
should appear darker. Night Vision
only shows objects that are warmer or
colder than the surroundings. It does
not detect brake lamps, turn signals,
emergency flashers, traffic lights,
or sign information.
Use this system as an aid by
occasionally glancing at the image. Do
not stare at the image or use the
image under well-lit conditions.
{Warning
Do not stare at the image while
driving as this might cause
important objects ahead not to be
seen. You could crash, and you or
others could be injured.
When a pedestrian or large animal is
detected, an amber box displays
around the pedestrian or animal on
the Night Vision display and an amber
pedestrian icon,
~, or animal icon,
!, displays on the instrument
cluster. This pedestrian icon is also
shown on the Head-Up Display (HUD).
When the system detects the vehicle
is approaching a pedestrian much too
quickly, the amber box turns red, and
a red flashing icon,
~, displays on the
HUD with rapid beeping or pulsing of
the Safety Alert Seat, if equipped.
System pedestrian icons, beeps, and
(if equipped) Safety Alert Seat pulses
can be set to Off through vehicle
personalization by turning off the
Front Pedestrian Braking system. See
“Front Pedestrian Detection ”in
“Collision/Detection Systems” under
Vehicle Personalization 0170.
