DESCRIPTION - ELECTRICALLY-ADJUSTABLE SEATS - Alfa Romeo 159 1.8 Fino a 12/05

The vehicle can be fitted with electrically adjustable front seats.A multifunction control on each seat includes:- adjustment of the backrest angle;- lengthwise adjustment of the seat;- front and rear height adjustment of the seat (rocker).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") for a few seconds memorizes the position; this can only take place with the TEG inserted (ON).To recall a previously memorized position briefly press the relevant button. When a new seat position is memorized any previously memorized settings on this button are automatically cancelled767Seat position memorization does not include heating start up769The seat is also equipped with a lumbar adjustment knob that makes it possible to improve comfort by altering the backrest support: this adjustment is always mechanical and not controlled by electric motors.The seat moving circuit is protected by two specific fuses located in the luggage compartment fuse box.
