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.

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.

Blizzard Conditions
Being stuck in snow can be in a serious situation.Stay with the vehicle unless there is help nearby.If possible, use theRoadside Service on page 8-7.To get help and keep everyone in the vehicle safe:
•Turn on theHazard Warning Flashers on page 4-3.
•Tie a red cloth to an outside mirror.
{WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
•Clear away snow from around the base of
your vehicle, especially any that is blockingthe exhaust pipe.
•Check again from time to time to be sure
snow does not collect there.
WARNING: (Continued)
WARNING: (Continued)
•Open a window about 5 cm (two inches) on
the side of the vehicle that is away from thewind to bring in fresh air.
•Fully open the air outlets on or under the
instrument panel.
•Adjust the Climate Control system to a setting
that circulates the air inside the vehicle andset the fan speed to the highest setting.See Climate Control System in the Index.
For more information about carbon monoxide, seeEngine Exhaust on page 3-34.
Snow can trap exhaust gases under your vehicle.This can cause deadly CO (carbon monoxide) gasto get inside. CO could overcome you and kill you.You cannot see it or smell it, so you might notknow it is in your vehicle. Clear away snow fromaround the base of your vehicle, especially anythat is blocking the exhaust.
To save fuel, run the engine for only short periods asneeded to warm the vehicle and then shut the engine offand close the window most of the way to save heat.

If No Steam Is Coming From The
Engine Compartment
If an engine overheat warning is displayed but no steamcan be seen or heard, the problem may not be tooserious. Sometimes the engine can get a little too hotwhen the vehicle:
•Climbs a long hill on a hot day.
•Stops after high-speed driving.
•Idles for long periods in traffic.
•Tows a trailer.
If the overheat warning is displayed with no sign ofsteam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature andto the highest fan speed. Open the windows asnecessary.
3. In heavy traffic, let the engine idle in N (Neutral) whilestopped. If it safe to do so, pull off the road, shift toP (Park) or N (Neutral) and let the engine idle.
If the temperature overheat gage is no longer in theoverheat zone or an overheat warning no longer displays,the vehicle can be driven. Continue to drive the vehicleslow for about 10 minutes. Keep a safe vehicle distancefrom the car in front of you. If the warning does not comeback on, continue to drive normally.
If the warning continues, pull over, stop, and park thevehicle right away.
If there is no sign of steam, idle the engine for threeminutes while parked. If the warning is still displayed, turnoff the engine until it cools down. Also, see!OverheatedEngine Protection Operating Mode!next in this section.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and themessage ENGINE OVERHEATED STOP ENGINE isdisplayed, an overheat protection mode which alternatesfiring groups of cylinders helps prevent engine damage.In this mode, you will notice a loss in power andengine performance. This operating mode allows yourvehicle to be driven to a safe place in an emergency.Driving extended miles (km) and/or towing a trailer in theoverheat protection mode should be avoided.
Notice:After driving in the overheated engineprotection operating mode, to avoid engine damage,allow the engine to cool before attempting anyrepair. The engine oil will be severely degraded.Repair the cause of coolant loss, change the oil andreset the oil life system. SeeEngine Oil onpage 6-13.
