Operation
Driving programmes
Your vehicle is equipped with an electronical-
ly-contr
olled automatic gearbox. Shifting up
or down depends on the programme selec-
ted.
For a calm driving style, the gearbox uses the
most economic programme. The gearbox
shifts up as quickly as possible and shifts
down as late as possible, thus increasing
driving economy.
With a sporty driving style, characterised by
sudden acceleration, heavy acceleration,
speeds that often increase and decrease and
maximum speed, the gearbox adapts to this
driving style when the accelerator is pressed
down fully (kick-down) by shifting down as
quickly as possible and can even shift down
by several gears at once.
Selecting the best driving programmes is an
endless job. Regardless of this, the driver can
also make the gearbox switch to a more dy-
namic gear shift programme by pressing the
accelerator quickly. This makes the automatic
gearbox shift down into a lower gear than the
one that would normally apply to the current
speed, allowing for more rapid acceleration
(e.g. to overtake another vehicle) without
having to press the accelerator until the kick-
down position. On shifting up in a corre-
sponding driving style, the gearbox returns to
the original programme.
When driving along mountain roads, the
gearbo
x adapts to the gradients. This avoids
having to frequently change gears when driv-
ing uphill. In Tiptronic mode, it is possible to
shift down manually when driving downhill to
use the braking effect of the engine.
Emergency program
A back-up programme exists in case of faults.
In the event of
a fault in the gearbox electron-
ics, it will continue to work in one of the cor-
responding back-up programmes. All seg-
ments of the screen are lit up or switched off.
The fault can be seen as follows:
●
The gearbox only engages certain gears
●
Reverse gear R cannot be en
gaged
●
The manual gearbox switches off in the
back-up programme
Note
If the gearbox switches to the back-up pro-
gramme, v
isit an Authorised Service as soon
as possible to solve the problem.
Gearbox malfunctions
Gearbox: Fault! Stop the ve-
hicle and place the lever in the
position P.
There is a fault in the gearbox. Stop the vehi-

l
e in a s
afe place and do not continue driv-
ing. Seek specialist assistance.

strictions. Reverse gear disa‐
bled
Take the vehicle to a specialised workshop
and have the fault repaired without delay.
Gearbox: System fault! You
can continue driving in D until
switching off the engine
Stop the vehicle in a safe place well away
from moving traffic. Seek specialist assis-
tance.
Gearbox: too hot. Adapt your
driving accordingly
Continue driving at moderate speeds. When
the warning lamp switches off, you can con-
tinue driving in a normal manner.

If the fault was caused by a gearbox with a
high temperature, this driver message will be
