Steptronic Sport transmission: Launch
Control
The concept
Launch Control enables optimum acceleration
on surfaces with good traction.
General information
The use of Launch Control causes premature
component wear since this function represents
a very heavy load for the vehicle.
Do not use Launch Control during the break-in,
refer to page 166, period.
To increase vehicle stability, activate DSC again
as soon as possible.
An experienced driver may be able to achieve
better acceleration values in DSC OFF mode, re‐
fer to page 122.
Requirements Launch Control is available when the engine is
warmed up, that is, after uninterrupted driving
of at least 6 miles/10 km.

Front-end collision
warning with City Brak‐
ing function
The concept
The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention is done
with limited force and duration.
The system is controlled via a camera in the
base of the mirror.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system reac‐
tions.
General information
The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.Detection range
It responds to objects if they are detected by
the system.
Information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations. ◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g., approach control warning with light brak‐
ing function. There is risk of an accident. Switch
all Intelligent Safety systems off prior to tow-
starting/towing. ◀
