The vehicle can be fitted with electrically adjustable front seats, in particular:lengthwise movement (forwards/backwards);height adjustment;backrest adjustmentEach of the adjustments is carried out by a specific electric motor.On the versions with "seats with a memory", 4 different positions can be memorized for the driver''s seat:two linked to the remote controls for opening/closing the doors: when the doors are locked using the remote control, the position of the seat and the door mirrors is acquired by the remote control. When the doors are unlocked using the remote control, the seat and the door mirrors resume the position memorized previously;two linked to the memory buttons on the actual seat.767the positions memorized also include the position of the door mirrors.The adjustments can be made with the ignition key in position M and for about 1 minute after the key is turned to position S.This complex logic is managed by the seats/mirrors with memory control unit which converses with the Body Computer via the CAN.The circuit is protected by a specific fuse, located in the additional fuse box.

The control unit for the seats/mirrors with a memory M076 manages the function of adjusting the seats according to the position memorized and also controls the movement of the door mirrors using information transmitted to the body computer node M001 via the CAN.The seats/mirrors with a memory control unit M076 receives a power supply (pins B7 and B8 connector A) from the line protected by fuse F32 located in the additional fuse box B098, and a signal supply (pin A7 connector A) from the Body computer node M001 (pin 3 connector F) with which it communicates (pin A5 and C5 connector A) via the CAN (pins 36 and 38 connector I of M001).The adjustment of the driver''s seat is controlled by switch H066 which converses (pins 1, 2, 4, 3) with control unit M076 (pins A3, B2, C3, B3 connector B respectively).The adjustment signals are managed by the seats/mirrors with memory control unit M076.The left front seat sliding adjustment motor N127, the left front seat front height adjustment motor N126 and the left front seat backrest motor N132 receive the control signals from pins B7 and A7, C8 and A1, B1 and C2 of connector B of control unit M076.The height, sliding and backrest position sensors, located in the respective motor units (N126, N127 and N132), refer the variations in the seat position to the control unit M076 with feedback signals: the three sensors receive a power supply (pin 4) from pin C6, a reference earth (pin 2) from pin C4 and send (pin 3) a signal respectively to pins C5, A5 and B4.The switch unit H068 is connected (pins 1, 3 and 4) to control unit M076 (pins A2, A4 and A6 connector A): it is possible in this way to recall the positions memorized previously.
