When the selector lever is pressed forward or
back, the manual mode is activated and the
Steptronic shifts the gear. The instrument clus-
ter shows M1 through M6.
Upshifts and downshifts are only carried out at a
suitable engine and vehicle speed, e.g. a down-
shift is not carried out at excessively high
engine speeds. The selected gear is briefly dis-
played in the instrument cluster, followed by the
current gear.
To use the automatic function again, move the
selector lever to the right into position D.
