Sensors
The solar sensor, located in thedefrost grille in the middle of theinstrument panel, monitors the solarheat. Do not cover the solar sensoror the system will not work properly.
There is also an exteriortemperature sensor behind the frontgrille. This sensor reads the outsideair temperature and helps maintainthe temperature inside the vehicle.Any cover on the front of the vehicleincluding a snow plow, could causeafalsereadinginthedisplayedtemperature.

Climate Controls 243
Some vehicles may have theexterior temperature sensor in thepassenger side mirror instead of thefront grille area.
The climate control system uses theinformation from these sensors tomaintain comfort settings byadjusting the outlet temperature, fanspeed, and the air delivery mode.The system may also supply coolerair to the side of the vehicle facingthe sun. The recirculation mode willalso be used as needed to maintaincool outlet temperatures.
Air Vents
Use the air vents in the center andon the side of the instrument panelto direct airflow. Use thethumbwheels near the air vents toopen or close off the airflow.
Air vents blow warm air on the sidewindows in cold weather. If Floor,Defog, or Defrost modes areselected, a small amount of air willcome from the vents close to thewindow. If the airflow is shut offusing the thumbwheels, warm airwill be directed to the otherinstrument panel vents. This isnormal operation.
Use the thumbwheels to turn ventairflow on or off based on the modeselected.
Operation Tips
.Clear away any ice, snow,or leaves from air inlets at thebase of the windshield that couldblock the flow of air into thevehicle.
.Keep the path under the frontseats clear of objects to helpcirculate the air inside of thevehicle more effectively.
.Use of non-GM approved hooddeflectors can adversely affectthe performance of the system.Check with your dealer beforeadding equipment to the outsideof the vehicle.

Service
All vehicles have a label underhoodthat identifies the refrigerant used inthe vehicle. The refrigerant systemshould only be serviced by trainedand certified technicians. The airconditioning evaporator shouldnever be repaired or replaced byone from a salvage vehicle.It should only be replaced by a newevaporator to ensure proper andsafe operation.
During service, all refrigerantsshould be reclaimed with properequipment. Venting refrigerantsdirectly to the atmosphere is harmfulto the environment and may alsocreate unsafe conditions based oninhalation, combustion, frostbite,or other health-based concerns.

{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 snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

For more information about CO,
seeEngine Exhaust0276.
To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See“Rocking the Vehicle to Get ItOut”later in this section.
The Traction Control System (TCS)can often help to free a stuckvehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0295.If TCS cannot free the vehicle, see“Rocking the Vehicle to Get it Out”following.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
For information about using tirechains on the vehicle, seeTireChains0419.

268 Driving and Operating
The switch used to adjust thepedals is on the center stack, belowthe climate controls.
Lift the switch up to move thepedals closer to your body. Pressthe switch down to move thepedals away.
Before you start driving, fully pressthe brake pedal to confirm theadjustment is right for you.
The vehicle may have a memoryfunction, which lets pedal settingsbe saved and recalled. SeeMemorySeats061.
Ignition Positions
The ignition switch has four differentpositions.
To s h i f t o u t o f P ( P a r k ) , t h e i g n i t i o nmust be in ON/RUN or ACC/ACCESSORY and the regular brakepedal must be applied.
0(STOPPINGTHEENGINE/LOCK/OFF) :When the vehicle is stopped,turn the ignition switch to LOCK/OFF to turn the engine off. RetainedAccessory Power (RAP) will remainactive. SeeRetained AccessoryPower (RAP)0271.
This position locks the ignition andsteering wheel. It also locks thetransmission on automatictransmission vehicles. The key canbe removed in LOCK/OFF.
The steering can bind with thewheels turned off center. If thishappens, move the steering wheelfrom right to left while turning thekey to ACC/ACCESSORY. If thisdoes not work, then the vehicleneeds service.
Do not turn the engine off when thevehicle is moving. This will cause aloss of power assist in the brakeand steering systems and disablethe airbags.
If the vehicle must be shut off in anemergency:
1. Brake using a firm and steadypressure. Do not pump thebrakes repeatedly. This maydeplete power assist, requiringincreased brake pedal force.
2. Shift the vehicle to N (Neutral).This can be done while thevehicle is moving. After shiftingto N (Neutral), continue to
