Brief description of components
The selector lever is built into the center console. The selector-lever cover contains the illuminated display for the selector-lever position. The engaged drive position is backlit on the gearshift diagram. The background light is activated by the wiping contact on the selector lever.
An interlock prevents inadvertent shifts to selector-lever positions "R" and "P". To cancel the interlock, press the button on the front of the selector lever knob.

The selector lever has the positions
P for parking: enables starting of the engine
R for reverse gear
N for neutral: enables starting of the engine
Towing the vehicle is only possible in this selector-lever position.
D for drive: automatic mode
Gears are shifted within the framework of the adaptive transmission control.
M/S "M" for manual operation = Steptronic
or "S"
for Sport program = automatic mode with sporting characteristic curves
- Manual downshifting
+ Manual upshifting
When the selector lever is in the position "M/S", the transmission is in the automatic mode with sports characteristic curves. The display in the instrument cluster change from "D" to "SD".
If the selector lever is now tilted towards "-" or "+" in the gearshift gutter "M/S", the electronics switch to Steptronic. The sustained manual operation via selector lever or rocker switches becomes active. The display in the instrument cluster changes from "SD" to "M1" to "M6".
In the manual mode, the transmission control only executes upshifts or downshifts with the matching engine speed and road speed.
Gearshifts that would lead to non-permitted high or low engine speeds are not permitted.
The M/S position is notified to the transmission control by the Steptronic switch directly via line (signal name: EGS_MGE or EGS_MGA). The Steptronic switch is integrated in the gear selector switch. The selector-lever settings of the Steptronic for shifting the individual gears up and down are notified to the transmission control directly across a line (signal names: EGS_UP; EGS_Down).
