Operating Instructions for End ustomer Please remove page and add to the vehicle operating instructions. Note: We recommend matching the heating time to the driving time. Heating time = driving time Example: For a driving time of approx. 0 min. (in one direction), we recommend not exceeding a switch-on time of 0 min. If the summer/winter switch option has been installed, this must be switched in accordance with the time of year. The heater unit will then only switch on the vehicle fan to ventilate the vehicle interior in the position Winter heat and in the position Summer. Before parking the vehicle, make the following settings: Air outlet to windshield Set fan to level "", or possibly "" Set temperature to "max." limatic 7 Air outlet faces upward Set temperature on both sides to "HI". limatronic 74 904070_EN 6
