Electric Power Management
The vehicle has Electric Power Management (EPM) thatestimates the battery's temperature and state of charge.It then adjusts the voltage for best performance andextended 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 voltagemove up or down. This is normal. If there is a problem,an alert 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 be spinningfast enough at idle to produce all the power that isneeded 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 at highspeed, heated seats, engine cooling fans, trailer loads,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 increaseengine idle speed to generate more power, wheneverneeded. It can temporarily reduce the power demandsof some accessories.
Normally, these actions occur in steps or levels, withoutbeing noticeable. In rare cases at the highest levels ofcorrective action, this action may be noticeable to thedriver. If so, a Driver Information Center (DIC) messagemight be displayed, such as BATTERY SAVERACTIVE, BATTERY VOLTAGE LOW, or LOWBATTERY. If this message is displayed, it isrecommended that the driver reduce the electrical loadsas much as possible. SeeDIC Warnings and Messageson page 4!48.
Battery Run-Down Protection
This feature shuts off the dome lamps if they areleft on for more than 10 minutes when the ignition is inLOCK/OFF. This helps to prevent the battery fromrunning down.

Highbeam On Light
This light comes on whenthe high-beam headlampsare in use.
SeeHeadlamp High/Low-Beam Changero n p a g e 4!5for more information.
Tow/Haul Mode Light
For vehicles with the tow/haul mode feature, thislight comes on when theTow/Haul mode has beenactivated.
For more information, seeTow/Haul Modeonpage 3!36.
Fuel Gage
When the ignition is on,the fuel gage shows abouthow much fuel the vehiclehas left in the tank.
An arrow on the fuel gage indicates the side of thevehicle the fuel door is on.
The gage will first indicate empty before the vehicle isout of fuel, but the vehicle's fuel tank should befilled soon.

APPROACH LIGHTING
This feature allows you to select whether or not to havethe exterior lights turn on briefly during low light periodsafter unlocking the vehicle using the Remote KeylessEntry (RKE) transmitter.
Press the customization button until APPROACHLIGHTING appears on the DIC display. Press the set/reset button once to access the settings for this feature.Then press the customization button to scroll throughthe following settings:
OFF :The exterior lights will not turn on when youunlock the vehicle with the RKE transmitter.
ON (default) :If it is dark enough outside, the exteriorlights will turn on briefly when you unlock the vehiclewith the RKE transmitter.
The lights will remain on for 20 seconds or until the lockbutton on the RKE transmitter is pressed, or the vehicleis no longer off. SeeRemote Keyless Entry (RKE)System Operationo n p a g e 3!4for more information.
NO CHANGE :No change will be made to this feature.The current setting will remain.
To select a setting, press the set/reset button while thedesired setting is displayed on the DIC.

Trailer Wiring Harness
Heavy-Duty Trailer Wiring Harness Package
The vehicle has a seven-pin universal heavy-duty trailerconnector attached to the rear bumper beam next to theintegrated trailer hitch.
The seven-wire harness contains the followingtrailer circuits:
.Yellow: Left Stop/Turn Signal
.Dark Green: Right Stop/Turn Signal
.Brown: Taillamps
.White: Ground
.Light Green: Back-up Lamps
.Red: Battery Feed*
.Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in theunderhood electrical center, but the wires are notconnected. They should be connected by yourdealer/retailer or a qualified service center.
If charging a remote (non-vehicle) battery, press thetow/haul mode button located at the end of the shiftlever. This will boost the vehicle system voltage andproperly charge the battery. If the trailer is too light fortow/haul mode, turn on the headlamps as a second wayto boost the vehicle system and charge the battery.

Headlamp Aiming
The vehicle has a visual optical headlamp aimingsystem. The aim of the headlamps have been preset atthe factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aimof the headlamps may be affected and adjustment maybe necessary.
If oncoming vehicles flash their high beams at you, thismay mean the vertical aim of your headlamps needs tobe adjusted.
It is recommended that the vehicle is taken to yourdealer/retailer for service if the headlamps need to beadjusted. It is possible however, to re-aim theheadlamps as described.
The vehicle should:
.Be placed so the headlamps are 25 ft. (7.6 m) froma light colored wall or other flat surface.
.Have all four tires on a level surface which is levelall the way to the wall or other flat surface.
.Be placed so it is perpendicular to the wall or otherflat surface.
.Not have any snow, ice, or mud on it.
.Be fully assembled and all other work stoppedwhile headlamp aiming is being performed.
.Be normally loaded with a full tank of fuel and oneperson or 160 lbs (75 kg) sitting on the driver seat.
.Have the tires properly inflated.
.Have the spare tire is in its proper location in thevehicle.
Headlamp aiming is done with the vehicle's low-beamheadlamps. The high-beam headlamps will be correctlyaimed if the low-beam headlamps are aimed properly.
To adjust the vertical aim:
1. Open the hood. SeeHood Releaseon page 7!15for more information.
2. Locate the center ofthe projector lens ofthe low!beamheadlamp.
3. Record the distance from the ground to the centerof the projector lens of the low!beam headlamp.

4. At a wall, measure from the ground upward (A) tothe recorded distance from Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall thewidth of the vehicle at the height of the mark inStep 4.
Notice:Do not cover a headlamp to improve beamcut-off when aiming. Covering a headlamp maycause excessive heat build-up which may causedamage to the headlamp.
6. Turn on the low-beam headlamps and place apiece of cardboard or equivalent in front of theheadlamp not being adjusted. This allows only thebeam of light from the headlamp being adjusted tobe seen on the flat surface.
7. Locate the vertical headlamp aiming screws, whichare under the hood near each headlamp assembly.
The adjustment screw can be turned with aE8 Torx®socket.
8. Turn the vertical aiming screw until the headlampbeam is aimed to the horizontal tape line. Turn itclockwise or counterclockwise to raise or lower theangle of the beam.

9. Make sure that the light from the headlamp ispositioned at the bottom edge of the horizontaltape line. The lamp on the left (A) shows thecorrect headlamp aim. The lamp on the right (B)shows the incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the oppositeheadlamp.
Bulb Replacement
For the proper type of replacement bulbs, seeReplacement Bulbs on page 7!56.
For any bulb changing procedure not listed in thissection, contact your dealer/retailer.
High Intensity Discharge (HID)
Lighting
{WARNING:
The low beam high intensity discharge lighting
system operates at a very high voltage. If you try
to service any of the system components, you
could be seriously injured. Have your dealer/
retailer or a qualified technician service them.
The vehicle may have HID headlamps. After an HIDheadlamp bulb has been replaced, you may notice thatthe beam is a slightly different shade than it wasoriginally. This is normal.
