This is normal and not an indication of a malfunction. The "AC OFF" function is used to permanently switch off the cooling function of the automatic climate control system. Warning! G If you turn off the cooling function, the vehicle will not be cooled when weather conditions are warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others. Select climate control settings tral climate control menu. Cen- 254
