- as of 1.1.00
- with CODE (241) Memory for electrically adjustable left front seat
- with CODE (242a) Memory for electrically adjustable right front seat

The front seat adjustment motor group consists of four DC motors for the various adjustment directions. The direction is changed by reversing the voltage polarity on the motor.
The seat position is sensed by one potentiometer each on the motors for the adjustment functions. The assignment for the direction of rotation from the motor to the potentiometer is accomplished automatically.

Function for individual motors, left front:
M27m1 Forward/back motor
M27m2 Rear raise/lower motor
M27m3 Front raise/lower motor
M27m5 Backrest forward/back motor

Function for individual motors, right front:
M28m1 Forward/back motor
M28m2 Rear raise/lower motor
M28m3 Front raise/lower motor
M28m5 Backrest forward/back motor

Group division
The adjustment functions are divided into two groups. It is only possible to actuate one motor per group simultaneously. When the seat adjustment switch is actuated for more than one adjustment function within one group, actuation is accomplished in the following sequence:

Group 1:
- Rear height adjustment

Group 2:
- Longitudinal adjustment
- Front height adjustment
- Backrest adjustment
