The cooling effect increases as the air in the passenger compartment becomes cooler. The ventilation is controlled by the ECC system, which takes into account the seat temperature, sunlight in the passenger compartment, and the ambient temperature. The ventilation can be used at the same time as seat heating. The ventilation system can be activated when the engine is running. There are three comfort levels that produce different cooling and dehumidification effects: Level three: press the button once for maximum output - three indicator lights come on. Level two: press the button twice for a lower output - two indicator lights come on. Level one: press the button three times for the lowest output - one indicator light comes on. Press the button a fourth time to switch off the function - the indicator light will go out.
