The knobs that control the optional heating and air conditioning system The heating system in the optional heating and air conditioning system operates the same as the heater only system. See The Heater Only System. To cool your vehicle quickly in warm weather, turn the SELECT knob to MAX A/C, turn the TEMP knob all the way to the end of the blue range (full left) and turn the FAN knob to HI. MAX A/C uses recirculated air and is the most fuel efficient way to cool your vehicle and can also be used in heavy traffic to prevent exhaust fumes from entering the vehicle. MAX A/C can also be used in high humidity areas for more efficient operation. If the interior of your vehicle is very warm, drive for the first few minutes with the windows open. This forces most of the hot, stale air out of the vehicle and allows the air conditioning to work faster. To cool your vehicle using outside air, turn the SELECT knob to NORM A/C, turn the TEMP knob all the way to the end of the blue range (full left) and turn the FAN knob to the desired speed between LO and HI. NORM A/C provides quieter system operation than MAX A/C. 81
