IntelliBeam™ Intelligent High-Beam
Headlamp Control System
If your vehicle has this feature, be sure to read this
entire section before using it.
IntelliBeam™ is an enhancement to the vehicle’s
headlamp system. Using a digital light sensor located
on the back of the rearview mirror, this system turns
the high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam™ system turns the high-beam
headlamps on when it is dark enough, there is no other
traffic present, and the IntelliBeam™ system is enabled.
Turning On and Enabling IntelliBeam™
AUTO3(IntelliBeam™ On/Off):Press and release
the IntelliBeam™ button on the inside rear view mirror.
The IntelliBeam™ indicator on the mirror turns on.
Once the system has been turned on, it remains on each
time the vehicle is started. Additionally, the IntelliBeam™
system must be enabled.
To enable the IntelliBeam™ System, turn the exterior
lamp control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On
Light appears on the instrument panel cluster when
the high-beams are on. SeeHighbeam On Light
on page 3-72. Your vehicle has variable intensity
high-beams. The high-beam indicator on the instrument
panel cluster comes on as soon as the high-beams
start to come on, and remains on until the high-beams
have completely turned off. All vehicles that have
IntelliBeam™, however, quickly turn off the high-beams
if the system detects the sudden presence of vehicle
lights ahead.
Driving with IntelliBeam™
IntelliBeam™ only activates the high-beams when
driving over 20 mph (32 km/h).
3-34

The high-beam headlamps remain on, under the
control of IntelliBeam™, until any of the following
situations occur:
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 high-beam headlamps are manually
turned on or you use the ash-to-pass feature.
SeeHeadlamp High/Low-Beam Changer on
page 3-9andFlash-to-Pass on page 3-13.
When either of these conditions occur, the
IntelliBeam™ feature is temporarily disabled until
the high-beam stalk is returned to the neutral
position. If either of these conditions occur and
IntelliBeam™ already has the high-beam headlamps
on, the IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off.
The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam™ is disabled until
the control is turned back to the AUTO position
and the AUTOMATIC LIGHTS ON message
displays on the DIC.
The IntelliBeam™ system is turned off at the inside
rearview mirror.
The vehicle’s speed drops below 15 mph (24 km/h).
IntelliBeam™ may not turn off the high-beams if the
system cannot detect other vehicle’s lamps because
of any of the following:
The others 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.
Your vehicle’s windshield is dirty, cracked,
or obstructed by something that blocks the view
of the IntelliBeam™ light sensor.
Your vehicle’s windshield is covered with ice,
dirt, haze, or other obstructions.
Your vehicle is loaded such that the front end of
the vehicle points upward, causing the IntelliBeam™
sensor to aim high and not detect headlamps
and taillamps.
You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
about six seconds. For this feature to work, automatic
lighting must be enabled. SeeHeadlamps on page 3-33
for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off if the windshield wiper control is turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
SeeLights On Reminder on page 3-72for additional
information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will make the turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is on,
the automatic lights are enabled, and
the transmission is not in PARK (P).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. The instrument panel will not be lit.
When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it is bright enough
outside, the low-beam headlamps will go off, and the
DRL will turn back on. If the vehicle is started in a
dark garage, the automatic headlamp system will
come on immediately. Once the vehicle leaves the
garage, it will take about one minute for the automatic
headlamp system to change to DRL if it is light outside.
3-37

Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
The fog lamp controls are located on the turn
signal/multifunction lever.
-(Fog Lamps):The band with this symbol is used to
turn the fog lamps on and off.
The parking lamps must be on for the fog lamps to work.
To turn the fog lamps on, turn the fog lamp band on
the lever up to the dot and release it. The band
will return to its original position.
To turn the fog lamps off, turn the fog lamp band up
to the dot and release it. The band will return to
its original position, and the fog lamps will turn off.
If the high-beam headlamps are turned on, the
fog lamps will also turn off. They will turn back on
again when you switch back to low-beam headlamps.
Some localities have laws that require the headlamps
to be on along with the fog lamps.
Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel®the following will happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch
is in the off position.
