Turning on the air conditioner
Press the heater fan switch handle, the indicator light in the center of the handle will come on.
Ventilation with outside air
In dry, warm weather, set the fan switch knob to the outside air ventilation position, the air temperature control knob to the stop counterclockwise, and the air flow distribution knob to any position desired.
Maximum cooling
Turn on the air conditioner and set the fan switch handle to the counterclockwise position. Fully open the side and central ventilation nozzles. When the desired temperature is reached, set the fan mode and air flow direction as desired.
When the air conditioner is on, the humidity in the car's interior decreases faster and fogged windows dry faster. Therefore, it is recommended to turn on the air conditioner when the air temperature is above +4°C and in humid weather.
