Abstract

A vehicle heating and/or air-conditioning system has an automatic heating and air-conditioning function. In a manual control mode, corresponding to an air quantity settable by the user with a first setting device and a desired interior temperature settable by a second setting device, a manual control of the actual interior temperature and the air quantity takes place. In an automatic-function control mode, corresponding to the desired interior temperature settable by the user and a selected air-conditioning style, an automatic-function control of the actual interior temperature takes place by controlling fans and air distribution flaps corresponding to the selected air-conditioning style. A characteristic fan curve and/or a characteristic air distribution curve is assigned to each air-conditioning style. A display unit, in which at least the air quantity manually selected by the user in the manual mode, and the air-conditioning style selected in the automatic mode uses identical illuminated symbols as its display.
