;(Parking Lamps):Turn the control to this position
to turn on the parking lamps together with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
5(Headlamps):Turn the control to this position to
turn on the headlamps, together with the previously
listed lamps and lights.
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.

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 turns off and does
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 disables
IntelliBeam™ and the IntelliBeam™ indicator on the
rearview mirror turns 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
automatically resets 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 at the
back of the 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 3-33
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

During that delay, the instrument panel cluster may
not be as bright as usual. Make sure the instrument
panel brightness lever is in the full bright position.
SeeInstrument Panel Brightness on page 3-41.
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. SeeDIC Warnings and Messages
on page 3-80.
The regular headlamp system should be turned
on when needed.
Light Sensor
The light sensor for the DRL is located on top of
the instrument panel. If the sensor is covered, it will
read dark, and the exterior lamps may come on
when they are not needed.
3-38

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.
3-39

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, the instrument panel
cluster might not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-41
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/ACCESSORY. Then start the
vehicle. The lamps will stay off until the parking brake
is released.
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,
the lamps will remain on until:
The exterior lamp switch is moved from off to
the parking lamp position.
A delay time that you select has elapsed.SeeVehicle Personalization on page 2-60to select
the delay time that you want. You can also select
no delay time.
If the ignition is turned off 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, the regular headlamp system
should be turned on when needed.
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.
3-40

Instrument Panel Brightness
Press the center knob on the DIC control panel until
the knob pops out. Then turn the knob clockwise
to brighten the lights or counterclockwise to dim
them. If the knob is turned completely clockwise,
the interior lamps turn on.
Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the
remote keyless entry transmitter unlock button.
If activated by the transmitter, the lighting will remain
active for about 25 seconds. The entry lighting system
uses the light sensor; it must be dark outside in order
for the lamps to turn on. The lamps turn off about
25 seconds after the last door is closed. They will dim
to off if the ignition is on, or immediately deactivate if
the power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument panel
displays can be adjusted by turning the instrument panel
brightness knob. SeeInstrument Panel Brightness
on page 3-41for additional information. Base Level Shown,

Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle
at a higher revolutions per minute (rpm) setting
than normal to make sure the battery charges.
High electrical loads may occur when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, the climate control fan at
high speeds, heated seats and engine cooling fans.If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass and the fan may cut back to a lower
speed. For more battery saving information, see
“Battery Saver Active Message” underDIC Warnings
and Messages on page 3-80.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly put the charge back in.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
