IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entiresection before using it.
IntelliBeam is an enhancement to the vehicle’sheadlamp system. Using a digital light sensor on therearview mirror, this system turns the vehicle’shigh-beam headlamps on and off according tosurrounding traffic conditions.
The IntelliBeam system turns the high-beam headlampson when it is dark enough, there is no other trafficpresent, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam button on the insiderear view mirror. The IntelliBeam indicator on themirror turns on to indicate the system is on. Once thesystem has been turned on, it remains on each time thevehicle is started, but the IntelliBeam system must beenabled.
To enable the IntelliBeam system, turn the exterior lampcontrol to AUTO, with the turn signal/multifunctionlever in its neutral position. The High-Beam On Lightappears on the instrument panel cluster when thehigh-beams are on. SeeHighbeam On Light onpage 4-61.

Reading Lamps
The reading lamps are located on the overhead consoleon the headliner and in the rear door opening. Theselamps come on automatically when any door is openedand it is dark outside.
For manual operation, press the button to turn them on.Press it again to turn them off.
If the reading lamps are left on, they automatically shutoff 10 minutes after the ignition has been turned off.
Footwell Lamps
For vehicles with footwell lamps, they are located underthe instrument panel and at the rear of the frontseats. These lamps provide soft light to the front andrear floor areas. They dim with the instrument panelcluster lights.
Footwell lighting brightness can be adjusted with theinstrument panel brightness control located belowthe exterior lamps control. SeeInstrument PanelBrightness on page 4-31. The footwell lights will turn offbefore the instrument panel lights are at their lowestlevel of brightness.
Battery Load Management
This feature monitors the vehicle’s electrical load anddetermines when the battery is in a heavy dischargecondition. During times of high electrical loading,the engine may idle at a higher revolutions per minute(rpm) setting than normal to make sure the batterycharges. High electrical loads may occur when severalof the following are on: headlamps, high beams, foglamps, rear window defogger, the climate control fan athigh speeds, heated seats and engine cooling fans.
If the battery continues to discharge, even withthe engine idling at a higher rpm setting, some electricalloads will automatically be reduced. When this occurs,the rear window defogger may take slightly longerto clear the glass, the heated seats may not get as warmas they usually do and the climate control fan may cutback to a lower speed. For more battery savinginformation, see “Battery Saver Active Message” underDIC Warnings and Messages on page 4-67.

Electric Power Management
The vehicle has Electric Power Management (EPM) thatestimates the battery’s temperature and state ofcharge. It then adjusts the voltage for best performanceand extended life of the battery.
When the battery’s state of charge is low, the voltage israised slightly to quickly bring the charge back up.When the state of charge is high, the voltage is loweredslightly to prevent overcharging. If the vehicle has avoltmeter gage or a voltage display on the DriverInformation Center (DIC), you may see the voltage moveup or down. This is normal. If there is a problem, analert will be displayed.
The battery can be discharged at idle if the electricalloads are very high. This is true for all vehicles. This isbecause the generator (alternator) may not bespinning fast enough at idle to produce all the powerthat is needed for very high electrical loads.
A high electrical load occurs when several of thefollowing are on, such as: headlamps, high beams, foglamps, rear window defogger, climate control fan athigh speed, heated seats, engine cooling fans, trailerloads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of thebattery. It does this by balancing the generator’s outputand the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, wheneverneeded. It can temporarily reduce the power demands ofsome accessories.
Normally, these actions occur in steps or levels, withoutbeing noticeable. In rare cases at the highest levelsof corrective action, this action may be noticeable to thedriver. If so, a Driver Information Center (DIC)message might be displayed, such as BATTERYSAVER ACTIVE, BATTERY VOLTAGE LOW, orLOW BATTERY. If this message is displayed, it isrecommended that the driver reduce the electrical loadsas much as possible. SeeDIC Warnings and Messageson page 4-67.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s batteryagainst drainage from the interior lamps, trunk lamp,glove box lamp, or the garage door opener. When theignition is turned off, the power to these features willautomatically turn off after 10 minutes. Power willbe restored for an additional 10 minutes if any door ortrunk is opened, or the courtesy lamp switch isturned on.

0(Defrost):This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshieldand side window outlets. When selected, the systemautomatically turns off recirculation and runs theair conditioning compressor, unless the outsidetemperature is at or below freezing. Recirculation cannotbe selected while in the defrost mode. Do not drivethe vehicle until all the windows are clear.
For professional vehicles, air will be allowed to flowthrough the rear outlets. For quicker defrost, press theAUX button on the front climate control system sothat the light is not lit.
#(Air Conditioning):Press to turn the air
conditioning system on or off and override the automaticsystem. When in AUTO, the air conditioning compressorcomes on automatically, as necessary. To avoidwindow fogging on rainy and humid days attemperatures above freezing, run the air conditioning.
The air conditioning system removes moisture fromthe air, so a small amount of water may drip under thevehicle while idling or after turning off the engine.This is normal.
:(Outside Air):Press to turn the outside air mode
on or off. An indicator light comes on to show it ison. Air is pulled from outside the vehicle.
Pressing?will cancel this mode.
?(Recirculation):Press to turn the recirculation
mode on or off. An indicator light below the buttoncomes on to show that this mode is on. This moderecirculates and helps to quickly cool the air inside thevehicle. It can be used to prevent outside air andodors from entering the vehicle. This mode cannot beselected while in the defog or defrost modes. If you try toselect the recirculation mode, the indicator lightflashes three times and turns off.
Operation in this mode during periods of high humidityand cool outside temperatures may result in increasedwindow fogging. If window fogging is experienced, selectthe defrost mode.
AUX:For vehicles with a rear climate control system,press to turn the rear climate control fan on for automaticoperation. After the AUX button is pressed, the indicatorlight comes on. Press the button again to turn theauxiliary fan off. SeeRear Climate Control System onpage 4-42.

Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something iswrong before it becomes serious enough to causean expensive repair or replacement. Paying attention tothe warning lights and gages could prevent injury.
Warning lights come on when there might be or there isa problem with one of the vehicle’s functions. Somewarning lights come on briefly when the engine is startedto indicate they are working.
Gages can indicate when there might be or there is aproblem with one of the vehicle’s functions. Often gagesand warning lights work together to indicate a problemwith the vehicle.
When one of the warning lights comes on and stays onwhile driving, or when one of the gages shows therecould be a problem, check the section that explains whatto do. Follow this manual’s advice. Waiting to dorepairs can be costly and even dangerous.
