Shift paddles for Steptronic Sport
transmission
The shift paddles on the steering wheel allow
you to shift gears quickly while keeping both
hands on the steering wheel.
▷Shift up: briefly pull right shift paddle.▷Shift down: briefly pull left shift paddle.▷With the respective transmission version,
the lowest possible gear can be selected by
pulling and holding the left shift paddle.
Gears will only be shifted at appropriate engine
and road speeds, for example downshifting is
not possible if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
If the shift paddles on the steering wheel are
used to shift gears in automatic mode, the
transmission temporarily switches to manual
mode.
If the selector lever is still in selector lever posi‐
tion D with the respective transmission version,
it is possible to switch back into the automatic
mode:
▷Pull and hold right shift paddle.
or▷In addition to the briefly pulled right shift
paddle, briefly pull the left shift paddle.
In the manual mode, after conservative driving
for a certain amount of time or if there has
been no acceleration or shifting of the shift
paddles within a certain amount of time, the
transmission switches back to automatic mode.

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 136, 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 97.
Requirements Launch Control is available when the engine is
warmed up, that is, after uninterrupted driving
of at least 6 miles/10 km.
To start with Launch Control do not steer the
steering wheel.
Start with launch control
While the engine is running:1. Press button and select SPORT with
Driving Dynamics Control, refer to
page 99.
The instrument cluster displays TRACTION

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
from the personal responsibility. Due to system
limits, warnings or reactions of the system may
not be output or they may be output too late or
incorrectly. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective 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. ◀

PrewarningThis warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a relatively high dif‐
ferential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking intervention The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake booster
is sufficiently quick and sufficiently hard step‐
ping on the brake pedal. The system can assist
with some braking intervention if there is risk of
a collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by actively
moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.System limits
Detection range The system's detection potential is limited.
Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐ tected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the
front windshield are dirty or covered.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
the more warnings are displayed. However,
there may also be an excess of false warnings.
