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 your vehicle’s
headlamp system. Using a digital light sensor on your
rearview mirror, this system will turn the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam™ system will turn your 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 turn on
to let you know the system has been turned on.
Once the system has been turned on, it will remain 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
will appear on the instrument panel cluster when
the high-beams are on. SeeHighbeam On Light on
page 3-72. Your vehicle is equipped with variable
intensity high-beams. The high-beam indicator on the
instrument panel will illuminate as soon as the
high-beams start to come on, and will remain on until
the high-beams have completely turned off. All
IntelliBeam™ equipped vehicles, however, will quickly
turn off the high-beams if the system detects the sudden
presence of vehicle lights ahead.
3-32

Driving with IntelliBeam™
IntelliBeam™ will only activate your high-beams when
driving over 20 mph (32 km/h).
The high-beam headlamps will 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 3-8and
Flash-to-Pass on page 3-12.
When either of these conditions occur, the
IntelliBeam™ feature will be 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 will be disabled and the
IntelliBeam™ light in the mirror will turn off.
The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam™ will be disabled until
the control is turned back to the AUTO position and
the AUTOMATIC LIGHTS ON message is displayed
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.
3-33

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 may need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
Disabling and Resetting IntelliBeam™ at
the Rearview Mirror
IntelliBeam™ can be disabled and reset to the original
factory setting by using the controls on the inside
rearview mirror.
AUTO
3(IntelliBeam™ On/Off):To disable the
system, press this button on the inside rearview mirror.
The IntelliBeam™ indicator will turn off and the will
not come back on until the IntelliBeam™ button
is pressed again.
When IntelliBeam™ has turned on the high-beams, pull
or push the high-beam stalk. This will disable
IntelliBeam™. The IntelliBeam™ indicator on the mirror
will turn off. To re-enable IntelliBeam™, press the
IntelliBeam™ button on the mirror.A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding this
button for 20 seconds until the light ashes three times.
If you accidentally activate this, the vehicle’s setting
will automatically be reset each time the ignition
is turned off and then on again; otherwise, refer to
the text above for resetting the system.
Cleaning the IntelliBeam™ Light Sensor
The light sensor is located
on the inside of the vehicle
in front of the inside
rearview mirror.
Clean the light sensor window, periodically, using glass
cleaner on a soft cloth. Gently wipe the sensor
window. Do not spray glass cleaner directly on the
surface of the sensor window.

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 3-31
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 3-71for 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 your front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. Your instrument panel will not be lit.
3-35

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 you start your vehicle in a dark
garage, the automatic headlamp system will come on
immediately. Once you leave the garage, it will take
about one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
lever is in the full bright position. SeeInstrument
Panel Brightness on page 3-39.
To operate your vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking lamp
position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to off and
back to AUTO.
An AUTOMATIC LIGHTS OFF message will appear on
the DIC, showing that automatic lighting has been
disabled.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Light Sensor
The light sensor for the DRL is located on top of the
instrument panel. If you cover the sensor, it will
read dark, and the exterior lamps may come on when
you do not need them.
3-36

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 front 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 you turn on the
high-beam headlamps, the fog lamps will also turn off.
They’ll 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.
3-37

With Twilight Sentinel®you will see the following
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.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-39
for more information.
You can idle the vehicle with the lamps off, even when it
is dark outside. First set the parking brake while the
ignition is in OFF/ACC. Then start the vehicle. The lamps
will stay off until you release the parking brake.Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, your lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
a delay time that you select has elapsed.
SeeVehicle Personalization on page 2-53to select the
delay time that you want. You can also select no
delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off
as soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after the
ignition is turned off. This protects against draining
the battery in case you have accidentally left the
headlamps or parking lamps on. The battery saver does
not work if the headlamps are turned on after the
ignition is turned off.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on.
