With the selector lever and the transmission mode switch (S16/5) it is possible to adapt the automatic sequence of the shift to particular operating conditions.

Although the shift range can be changed in the forward gears while driving, the electronic transmission control prevents a gearshift if the engine speed is too high.

In position "C" (comfort program) of the transmission mode switch (S16/5) a lower overall ratio and therefore a lower output torque is available when driving backwards and forwards. This allows the vehicle to move off more gently. In addition, the gears are not driven to maximum revs.
