The position display in the instrument cluster (A1) is actuated by the ETC [ETC] control unit (N15/3) via the engine compartment CAN.

The program selection display in the instrument cluster (A1) is actuated by the electronic selector lever module control unit (N15/5) likewise via the engine compartment CAN.

The shift pattern display (87) is illuminated when the driving lights are switched on.

Program selection "W/S" 

The program selection performed at the transmission mode switch (S16/5) remains stored after driving for approx. 1 minute and is then displayed again once the engine is started. The driving time required of approx. 1 minute is due to the system.

Program selection "M" 

The program selection "M" (manual program) performed at the transmission mode switch (S16/5) does not remain stored. The standard program "S" is displayed once the engine is started again.
