Instruments and controls Seats Operation Driving Instrument cluster display 78 Practical hints Car care Technical data Index Seat ventilation system The buttons are located on each door. Seat ventilation can be activated manually with the electronic key in starter switch positions 1 or 2, or by the summer opening function, see page 45. Notes: When in operation, the seat ventilation system consumes a large amount of electrical power. It is not advisable to use the seat ventilator longer than necessary. The seat ventilators may automatically switch off if too many power consumers are switched on at the same time or if the battery charge is low. In this case, one or more indicator lamps will blink. The seat ventilation switch back on again automatically as soon as sufficient voltage is available. If the blinking of the indicator lamps is distracting to you, the seat ventilators can be switched off. The maximum ventilation level (level 3) is automatically selected if the driver's seat ventilation is activated by the summer opening function, see page 45.
