04 Comfort and driving pleasure Climate system Introduction Air conditioning The vehicle is equipped with Electronic Climate Control (ECC). The climate control system cools, heats or dehumidifies the air in the passenger compartment. NOTE The sunlight sensor monitors which side of the car that is most exposed to sunlight.
