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 into the higher gear just
before the maximum permissible engine speed is reached.
If you select a lower gear, the automatic gearbox 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 the 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.
A functional fault can have the following effect:
The gearbox only shifts into certain gears.
The reverse gear R cannot be used.
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.
