v
er is in
the positions P, D, N and S in addition to when
in Tiptronic mode. With the selector lever in P,
the engine will also remain switched off when
you take your foot off the brake pedal. In or-
der to start the engine up again the accelera-
tor must be pressed, or another gear engag-
ed or the brake released.
If the selector lever is placed in R while stop-

Change from D to P to prevent the engine
from accidentally starting when passing
through R.
Additional information about vehicles with
Adaptive Cruise Control (ACC)
In vehicles with ACC function, the engine will
start up again in certain operating conditions
if the radar sensor detects that the vehicle
ahead drives off again.
WARNING
●
Never switch the engine off until the vehi-
cle is st
ationary. The operation of the brake
and steering will not be fully guaranteed.
More force will be needed to turn the steer-
ing wheel or to brake. You could suffer an
accident and even serious injuries.
●
To avoid injury, make sure that the Start
-
Stop system is switched off when working
in the engine compartment

Note
●
In vehicles with an automatic gearbox,
you can control whether the engine should
s
witch off or not by reducing or increasing
the brake force applied. While the vehicle
remains stopped, the engine will not stop if
the brake pedal is slightly pressed, in traffic
jams with frequent stopping and starting
for example. As soon as strong pressure is
applied to the brake pedal, the engine will
stop.
●
When stopped, the brake pedal must be
kept pressed to ensure that the vehicle
does not move.
●
If the engine “stalls” with a manual gear-
box, it can be directly started up again by
immediately pressing the clutch pedal.
●
With an automatic gearbox, if the lever is
placed in position D, N or S after engaging
reverse gear, 10 km/h (6 mph) in a forwards
direction must be reached for the system to
be in a status to stop the engine.
