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 257. 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).
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.
213

The high-beam headlamps are manually
turned on or you use the ash-to-pass feature.
SeeHeadlamp High/Low-Beam Changer on
page 183andFlash-to-Pass on page 188.
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.

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 256for 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.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 220.
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.
216

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.
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.
217

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 264.
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 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.
221

The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 264.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s
battery against drainage from the interior
lamps, trunk lamp, glove box lamp, or the garage
door opener. When the ignition is turned off,
the power to these features will automatically turn
off after 10 minutes (three minutes if a new car
has 15 miles (24 km) or less). Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy
lamp switch is turned on.
222

Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high
in your eld of view, it may take you more
time to see things you need to see when it
is dark outside. Be sure to keep the HUD
image dim and placed low in your eld
of view.
If equipped, the Head-Up Display (HUD) allows
you to see some of the driver information that
appears on your instrument panel cluster on the
windshield.
The information may be displayed in English or
metric units and appears as an image focused out
toward the front of your vehicle. To change
from English to metric units, seeDIC Controls and
Displays on page 258.
The HUD consists of the following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Driver Shift Control Transmission Feature,

Highbeam On Light
This light comes on
whenever the
high-beam headlamps
are on.
See “Intellibeam™ Intelligent High-Beam
Headlamp Control System” underHeadlamps on
page 211andHeadlamp High/Low-Beam
Changer on page 183for more information.
Fuel Gage
The fuel gage shows
approximately how
much fuel is in the tank.
It works only when
the engine is on.If the fuel supply gets low, the Fuel Level Low
message will appear on the DIC and a single
chime will sound. SeeDIC Warnings and
Messages on page 264for more information.
Here are a few concerns some owners have had
about the fuel gage. All of these situations are
normal and do not indicate that anything is wrong
with the fuel gage:
At the gas station the gas pump shuts off
before the gage reads full.
The gage may change when you turn, stop
quickly or accelerate quickly.
It takes a little more or less fuel to ll the tank
than the gage indicated. For example, the gage
may have indicated that the tank was half full,
but it actually took a little more or less than half
the tank’s capacity to ll the tank.
