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.

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.
4-33

Battery Run-Down Protection
This feature helps prevent the battery from beingdrained, if the interior courtesy lamps, reading/maplamps, visor vanity lamps or trunk lamp are accidentallyleft on. If any of these lamps are left on, theyautomatically turn off after 10 minutes, if the ignition isoff. The lamps will not come back on again untilone of the following occurs:
•The ignition is turned on.
•The exterior lamps control is turned off, then on
again.
The headlamps will timeout after 10 minutes, if they aremanually turned on with the ignition on or off.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug inelectrical equipment, such as a cellular telephone.
If the vehicle has a center console, the power outlet islocated inside the lower storage area. Some vehiclesmay have an outlet on the right front lower part ofthe driver’s seat and under the climate control systemnext to the ashtray. SeeCenter Console Storageon page 3-55.
There are two accessory power outlets in the rear seatarea located on the door armrests next to theashtrays.
There may be a small cap that must be removed toaccess the accessory power outlet. When not using theoutlet be sure to cover it with the protective cap.
The accessory power outlet can be used at any time.
Notice:Leaving electrical equipment plugged in foran extended period of time while the vehicle is offwill drain the battery. Power is always suppliedto the outlets. Always unplug electrical equipmentwhen not in use and do not plug in equipmentthat exceeds the maximum 20 ampere rating.
Certain accessory power plugs may not be compatibleto the accessory power outlet and could result inblown vehicle or adapter fuses. If you experience aproblem see your dealer/retailer for additionalinformation on the accessory power outlets.
Notice:Adding any electrical equipment to thevehicle can damage it or keep other componentsfrom working as they should. The repairs would notbe covered by the vehicle warranty. Do not useequipment exceeding maximum amperage rating of20 amperes. Check with your dealer/retailer beforeadding electrical equipment.

Automatic Operation
AUTO9(Automatic Fan):When this position is
selected on the fan control, the system adjusts the fanspeed. If the OnStar®system is activated when thisposition is selected, the climate control fan speedwill lower.
AUTO (Automatic Mode):
1. Turn the fan control to the AUTO position.
2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable settingbetween 21°C (68°F) and 26°C (78°F).
Choosing the coldest or warmest temperature settingwill not cause the system to heat or cool any faster.In cold weather, the system will start at reduced fanspeeds to avoid blowing cold air into the vehicle untilwarmer air is available. The system starts outblowing air at the floor but may change modesautomatically as the vehicle warms up to maintain thechosen temperature setting. The length of timeneeded to warm the interior depends on the outsidetemperature and temperature of the vehicle.
4. Wait 20 to 30 minutes for the system to stabilize inorder for the system to regulate automatically. Thenadjust the temperature as necessary to find yourcomfort setting.
Do not cover the solar sensor located in the center ofthe instrument panel near the windshield. For moreinformation on the solar sensor, see “Sensors” later inthis section.
After the vehicle is started, the display shows the interiortemperature settings and the outside temperature.
If the AUTO position is selected on the fan or modecontrol, the system automatically controls the airconditioning compressor. The A/C compressor will runautomatically even at cool outside temperatures in orderto dehumidify the air. The A/C indicator light is lit whenthe system is operating automatically, even at near
freezing outside temperatures. Press#on the fan
control to turn off the A/C. For improved window clearingperformance in defog or defrost modes, the A/Ccompressor runs automatically.
h(AUTO RECIRCULATION):If the AUTO position
is selected on either the fan or mode control, thesystem automatically controls the air inlet to supplyfresh outside air or recirculate the interior air to cool thecar faster. The light on the recirculation button willcome on when the system changes to recirculation.
Outside air can be forced by pressinghwhen
the light is lit. For vehicles without rear climate controls,
press:to force outside air. The next time AUTO
fan or mode is selected, the air inlet will reset back toAUTO operation.

Manual Operation
9(Off):Turns the entire climate control system off.
Outside air still enters the vehicle and is directed to thefloor. The airflow direction and temperature can beadjusted, as indicated below.
If the temperature is adjusted while the system is off,the display will light to show the current settings.
wx(Driver’s Temperature Controls):Press the up
or down buttons next to the fan control to manuallyincrease or decrease the temperature inside the vehicle.
wx(Passenger’s Temperature Controls):Press
the up or down buttons next to the air deliverymode control to manually increase or decrease thetemperature for the front passenger. If the passengerclimate control system is off, pressing one of thesebuttons turns it on.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. Turning thiscontrol completely counterclockwise will turn onthe automatic fan operation. If the airflow seems lowwhen the fan speed is at the highest setting, thepassenger compartment air filter may need to bereplaced. SeePassenger Compartment Air Filter onpage 4-44.
Air Delivery Mode Control:Turn clockwise orcounterclockwise to change the current airflow mode.
Select one of the following:
AUTO:Turns on the automatic delivery mode operation.
F(Vent):Air is directed to the instrument panel
outlets.
*(Bi-Level):Air is divided between the instrument
panel and the floor outlets. In automatic operation,cooler air is directed to the upper outlets and warmer airto the floor outlets.
7(Floor):Air is directed to the floor outlets with some
air directed to the side window outlets and thewindshield.
If recirculation is selected, it only stays on for threeminutes to reduce windshield fogging.
W(Floor/Defog):This mode clears the windows of
fog or moisture. Air is directed to the floor outlets, withsome air going to the side window outlets andwindshield. When selected, the system turns offrecirculation and runs the air conditioning compressorunless the outside temperature is at or below freezing.The recirculation mode cannot be selected while inthe floor/defog mode.
4-38

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.

There is also an interiortemperature sensorlocated next to the steeringwheel that measures thetemperature of the airinside the vehicle.
There is also an exterior temperature sensor locatedbehind the front grille. This sensor reads the outside airtemperature and helps maintain the temperatureinside the vehicle. Any cover on the front of the vehiclecould cause a false reading in the displayedtemperature.
In order to prevent false temperature readings atstartup, the displayed temperature will not change untilthe following occurs:
•Vehicle speed is above 16 km/h (10 mph) for
5 minutes.
•Vehicle speed is above 51 km/h (32 mph) for 2 and
a half minutes.
The climate control system uses the information fromthese sensors to maintain your comfort setting byadjusting the outlet temperature, fan speed, and the airdelivery mode. The system may also supply coolerair to the side of the vehicle facing the sun. Therecirculation mode will also be used as needed tomaintain cool outlet temperatures.
Outlet Adjustment
For the front outlets, use the thumbwheel located beloweach outlet to change the direction of the airflow. Use thethumbwheel located next to the outlets to shut the airflowor to open the outlets and re-direct the air.
For the rear outlets, slide the lever left or right and up ordown to change the direction of the airflow.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that mayblock the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle moreeffectively.
