Function Of Manual Drive Mode Selection: Notes

With the selector lever and the transmission mode switch (S16/5) on the floor shift it is possible to adapt the automatic gearshift sequence t suit specific operating conditions.

The shift range can in fact be changed in the forward gears while driving, however the electronic transmission control (ETC) prevents a shift at an unacceptably high engine speed.

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.

In position "M" (manual program) of the transmission mode switch (S16/5) all the forward gears can be engaged directly by means of the selector lever (touch shift "+" or "-") or by operating the left steering wheel gear shifter (S110/2) or right steering wheel gear shifter (S111/2).

A shift is not carried out at an unacceptably high or low RPM.
