H Fan speed adjustment The H (left) knob on the control is the fan control knob which controls the volume of air flow. Rotate the H knob to the right to increase fan speed and increase the amount of air entering the vehicle. Four fan speed positions are available and are indicated by dots beside the H control knob. The largest dot is high speed position. Airflow selections Q (Panel) Use Q to bring outside air through the instrument panel registers. You can heat the air in this position by rotating the temperature knob into the red area. The air CANNOT be cooled below the outside temperature regardless of the temperature knob setting. Select A/C or MAX A/C to get cool air through the instrument panel registers. A/C Select A/C to get refrigerated outside air through the instrument panel registers. The A/C position is used for cooling except when it is extremely hot or fast cooling of the vehicle is needed. Then, select MAX A/C for fast cooling and return to A/C when you are comfortable. MAX A/C The MAX A/C position produces cool air more rapidly to provide faster cooling of your vehicle. This is possible because cooler air is drawn from inside the passenger area and refrigerated again instead of using warmer outside air. Using inside air will also make the fan sound louder and is normal when using MAX A/C. The air flow will be from the instrument panel registers. 76
