Controls in detail 4-zone automatic climate control The climate control is a 4-zone intelligent climate control system. Your vehicle interior is divided into 4 zones. With the help of a sun sensor, the climate control determines the relation of the sun to the vehicle and automatically adjusts the inside temperature for every individual zone. You can set the temperature for each of the 4 zones separately. The climate control is operational whenever the engine is running. It cools the vehicle's interior according to the angle and intensity of the sun's rays, the outside temperature and the selected temperature. You can operate the climate control system in either the automatic or manual mode. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. Warning! G When operating the climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burn or frostbite to unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distribution controls ( page 190) or ( page 191) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin. 192
