The temperature can be adjusted between +16 °C (+60 °F) and +28 °C (+84 °F) by turning the rotary controls -1-. Outside this range, LO or HI will appear on the air conditioner display. In the two extreme settings the air conditioner operates continuously with maximum cooling or heating output, and the temperature is not regulated automatically.

The controls in the rear console Fig. 97► are used to regulate the temperature in the rear cabin.

You can adjust the blower speed manually using the rocker switch -4-.
