Description - ELECTRICALLY-ADJUSTABLE SEATS - Fiat STILO 1.4 16v da 01/04


The car may have electrically-adjustable front seats.The controls located on each seat include:knob for adjusting the backrest angleknob for lengthwise and height adjustmentknob for lumbar adjustment (makes it possible to alter the support, improving comfort)The system also makes it possible to memorize and recall three different positions for the driver''s seat (and the door mirrors): after the position of the seat and the door mirrors has been adjusted, pressing one of the buttons (''1'', ''2'' or ''3'') memorizes the position. (this can only be done with the igntion switched ON).If the button is pressed later on, with the door open, the seat moves automatically and stops in the position memorized.767The memorizing of the seat positions does not include lumbar adjustment or switching on the heating.The electrical adjustment of the seats can only be carried out with the ignition ON or for around 1 minute with the key turned OFF or extracted

The three door version is equipped with an Easy Entry function to facilitate access to the rear seats; when the front seat backrest is moved forwards, the entire seat automatically slides forward to the end of travel position to faciliate access to the rear seats; when the backrest is returned to its normal position, the seat automatically moves backwards.767if the seat encounters an obstacle during this operation (the legs of the rear passenger), the travel is interrupted and the seat stops and then moves slightly forwards.The seat movement system is operated by a special relay and protected by two specific fuses, located in the luggage compartment fuse box.
