than 2 seconds.
The selector lever only locks when the is vehi-
cle stationary or driving at a speed lower
than 5 km/h (3 mph). At a higher speed, it au-
tomatically disconnects in the N position.
Interlock button
The interlock button on the selector lever
knob prevents the driver from inadvertently
engaging a gear. Press the button to unlock
the selector lever.
Safety interlock for ignition key 1)
After switching the ignition off, the ignition key
can be removed only when the selector lever
is in position P. If the key is not in the ignition,
the selector lever is locked in position P.
Driving programmes Your vehicle is equipped with an electronical-
ly-contr
oll
ed aut
omatic 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 lat
e as possible, thus increasing driv-
ing 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 automat-
ic gearbox shift down into a lower gear than
the one that would normally apply to the cur-
rent speed, allowing for more rapid accelera-
tion (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
gearbox 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 ev
ent of a f
ault in the gearbox electron-
ics, it will continue to work in one of the corre-
sponding back-up programmes. All segments
of the screen are lit up or switched off.
The fault can be seen as follows:
