Climate Controls Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle. @ FAN: Move this lever to select the speed of the fan. Moving the lever between LOW and HIGH will decrease or increase the fan speed. The fan will be off when the system is off. To change the current mode, select one of the following: REGIRC (Recirculation): This mode keeps outside air from coming in the vehicle. It can be used to prevent outside air and odors from entering your vehicle or to help heat or cool the air inside your vehicle more quickly. Press this button to turn the recirculation mode on or off. When the button is pressed, an indicator light will come on. You may not use RECIRC with FRONT defrost or BLEND. VENT: This mode directs air to the instrument panel outlets. HTR (Heater): This mode directs most of the air to the floor outlets with some air directed to the outboard outlets (for the side windows) and some air directed to the windshield. BLEND: This mode splits the airflow between the windshield and the floor outlets. The air conditioning compressor will be operating. TEMPERATURE: This lever is used to adjust the temperature of the air coming through the system. Moving the lever between COOL and WARM will change the temperature of the air coming through your outlets. 3-23
