The folding function of the rearscreen blind consists of an up/down movement of the actual blind, used to shield the passengers in the rear seats from the sun.The device is entirely managed by the luggage compartment control unit: in addition to acquiring the command from a special switch, it determines the movement of the blind by means of a single motor which, depending on the polarity, moves it up or down. This movement finishes in the end of travel position; the blind cannot be placed in intermediate positions: it is either fully raised or fully lowered.If, the blinds have been operated at least four times within 25 seconds, the control unit inibits the operation for a period of 30 seconds, bringing the last movement, which is always the opposite of the starting movement, to an end.The electrical movement of the blind can only be activated with the ignition switched ON (INT). he device is excluded temporarily during start-up (INT/A).
