Driving with IntelliBeam™
IntelliBeam only activates the high-beams when drivingover 20 mph (32 km/h).
The high-beam headlamps remain on, under theautomatic control of IntelliBeam, until any of thefollowing 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 vehicle’s speed drops below 15 mph (24 km/h).
•The headlamp stalk is moved forward to the
high-beam position or the flash-to-pass feature isused. SeeHeadlamp High/Low-Beam Changeron page 4-6andFlash-to-Pass on page 4-10.
When either of these conditions occur, theIntelliBeam feature is disabled and the IntelliBeamlight in the mirror turns off until the high-beam stalk isreturned to the neutral position.
•If IntelliBeam was using low-beams prior to this
action, the IntelliBeam feature is temporarilydisabled until the stalk is returned to theneutral position.
•The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam is disabled until thecontrol is turned back to the AUTO position.
•The IntelliBeam system is turned off at the inside
rearview mirror.
IntelliBeam might not turn off the high-beams if thesystem cannot detect other vehicle’s lamps because ofany of the following:
•The other 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 theIntelliBeam light sensor.
•Your vehicle’s windshield is covered with ice, dirt,
haze, or other obstructions.

Wiper Activated Headlamps
This feature activates the headlamps and parking lampsafter the windshield wipers are turned on and havecompleted eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, thewiper-activated headlamps immediately turn off. Thewiper-activated headlamps also turn off if the windshieldwipers are turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp controlis left on in either the headlamp or parking lamp positionand the driver’s door is opened with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier forothers to see the front of your vehicle during theday. Fully functional daytime running lamps are requiredon all vehicles first sold in Canada.
The DRL system makes the turn signal lamps come onwhen the following conditions are met:
•It is still daylight and the ignition is on.
•The exterior lamp control is in the off position.
•The transmission is not in P (Park)
(United States only).
•The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control Systemon page 4-36.
When DRL are on, no other exterior lamps such as theparking lamps, taillamps, etc. will be on when theDRL are being used. The instrument panel will not be litup either.
When automatic lighting is on and it is dark enoughoutside, the turn signal lamps turn off and normallow-beam headlamp operation occurs.
When automatic lighting is on and it is bright enoughoutside, the regular lamps go off, and the DRLtakes over. If the vehicle is started in a dark garage, theautomatic headlamp system comes on immediately.Once you leave the garage, it will take approximatelyone minute for the automatic headlamp system tochange to DRL if there is light outside. During that delay,the instrument panel cluster may not be as bright asusual. Make sure the instrument panel brightness knobis in the full bright position. SeeInstrument PanelBrightness on page 4-31.
Turning on automatic lighting or the headlamps willdeactivate the DRL. If the parking lamps or thefog lamps were turned on instead, the DRL will stilldeactivate.

turn the fog lamps on or off. A light comes on inthe instrument panel cluster when the fog lamps are inuse. SeeInstrument Panel Cluster on page 4-47.The ignition must be in the ON/RUN position for thefog lamps to work.
The fog lamps will go off when the headlamps arechanged to high-beam.
Some localities have laws that require the headlamps tobe on along with the fog lamps.
Cornering Lamps
The cornering lamps come on when the headlamps orparking lamps are on and you signal a turn with themultifunction lever. They provide more light forcornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exteriorlamps will turn off about 10 minutes after the ignitionis turned to LOCK/OFF and a door has been opened.This protects against draining the battery if theheadlamps or parking lamps are accidentally left on.If you need to leave the lamps on for more than10 minutes, use the exterior lamp control to turn thelamps back on after the ignition is turned to LOCK/OFFand any door is opened.

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.
