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.
