Manual drive mode selection, function - GF27.60-P-3011NQL

TRANSMISSION 722.9 in MODEL 209 with CODE (428) Steering wheel shift buttons 

By means of the selector lever and the transmission modes switch (S16/5) (except code P98 Black Series) or the automatic transmission program selection button (S16/12) (with code P98 Black Series) it is possible to adapt the automatic sequence of the circuit to particular operating conditions.

The shift range can in fact be changed in the forward gears while driving, however the fully electronic transmission control (VGS) prevents the engine from over-revving by way of upshifts close to the maximum governed engine speed.

In transmission mode "C" (except code P98 Black Series), a shorter shift range (shifting at lower engine speed) and thus a lower output torque is available when starting off in the forwards and reverse gears. This allows the vehicle to move off more gently. In addition, the gears are not driven to maximum revs.

In manual transmission mode "M" all the forwards gears can be shifted by means of the selector lever or left steering wheel gear shifter (S110/2) and right steering wheel gear shifter (S111/2) (up to 31.5.06) or steering wheel gear shifter MINUS (S110/1) and steering wheel gear shifter PLUS (S111/1) (as of 1.6.06).

Gear changes required which would result in unacceptably high or low engine speeds are not executed.
