If the right front door control unit receives the message "Reverse gear engaged" via CAN B bus by the central gateway control unit, the right outside mirror is moved to park position stored for the transmitter key (A8/1).

Aborting the function
The right outside mirror is automatically returned to the original position, when:
- the reverse gear signal is not recognized after 10 s or
- the vehicle speed is greater than 10 km/h or
- the left/right outside mirror adjustment switch is switched to driver's mirror position

It is also then returned to the original position if the right outside mirror is adjusted manually in the park position via the outside mirror adjustment switch. If the right outside mirror is located in the park position with circuit 15 OFF, it is returned after 10 s when c. 15 is switched back on and the transmission no longer shifted to reverse. If reverse gear is recognized with circuit 15 ON, the mirror moves to the associated park position for the transmitter key in use after 0.6 s.

Store park position

Function requirements
- Circuit 15 ON or circuit 15R ON
- Valid memory block number recognized

In order to store the park position of the passenger mirror, select right outside mirror adjustment selection switch with LED function in the driver power window and outside mirror adjustment switch group

Then it is necessary to adjust the desired park position for the right outside mirror manually with the outside mirror adjustment raise/ lower, in/out rocker switch on the driver power window switch and outside mirror adjustment.

The park position is stored by the left front seat adjustment switch group.
After shortly pressing the memory switch for min. 40 ms, the momentary outside mirror position in the right door control unit is stored as park position.

The storage request is transmitted to the left front door control unit by the driver power window and outside mirror adjustment switch group and from there, relayed to the right front door control unit via the CAN B bus The position and storage data is stored in the right front door control unit.

If the desired park position is not yet correct, it can be corrected afterwards by adjusting the rearview mirror manually even when the "park position" function is activated.
