The Tiptronic allows the driver to also shift gears manually.
Switching over to manual shifting

gearbox has switched over, 5 4 3 2 1 appears in the display, with the
gear engaged being highlighted.
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position) ⇒fig. 124 . Shifting down gears
– One-touch back of the selector lever (in the Tiptronic position) .
It is possible to switch over to manual both when the car is stationary and also when
driving.
When you accelerate, the gearbox shifts up
automatically in gears 1, 2, 3 and 4 into
the next higher gear just before the maximum permissible engine speed is reached.
If you select a lower gear, the automatic ge arbox does not shift down until there is
no risk of the engine overrevving.
If you operate the kickdown function, the gearbox shifts into a lower gear in line
with the vehicle speed and engine speed.
Emergency programme
An emergency programme exists in th e event of a fault in the system.
The gearbox operates in a corresponding emergency programme if there are func-
tional faults in the gearbox electronics. This is indicated by all of the segments in the
display lighting up or going out.
It is possible to continue to move the selector lever into all the positions. The
gearbox always shifts into 4th gear in the positions D, 4 , 3 and 2. It is also possible
to continue to engage reverse gear in the position R.
The manual shift programme (Tiptronic) is switched off in the emergency mode.
If the gearbox has switched over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.
