In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.
▷On uphill grades or on a slope, also secure
the vehicle, for example with a wheel
chock.◀

▷Shift down: briefly pull left shift paddle.▷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.
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.
It is possible to switch 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.
Displays in the instrument cluster
The selector lever position is dis‐
played, for example: P.
Manually release the transmission lock
Should the selector lever be blocked in selector
lever position P despite the ignition being
turned on, the brake being depressed and the
unlock button being pressed, the transmission
lock can be manually canceled:
Before unlocking the transmission lock man‐
ually, set the parking brake to prevent the vehi‐
cle from rolling away.
1.Loosen the selector lever sleeve together
with the lower retaining ring and possibly
the Driving Dynamics Control from the cen‐
ter console. For this purpose, pull the re‐
taining ring and possibly the Driving Dy‐
namics Control upward on the rear edge.
2.Lift the sleeve. Unplug the cable connector
if needed.
3.Using the screwdriver from the onboard ve‐
hicle tool kit, refer to page 203, press the
yellow release lever downward, arrow.
4.Move the selector lever slightly toward the
rear; to do this press the unlock button on
the front of the selector lever.
Release the release lever.
5.Bring the selector lever into the desired po‐
sition.
Steptronic Sport transmission: Launch
Control
The concept
Launch Control enables optimum acceleration
on surfaces with good traction.
Seite 77DrivingCONTROLS77
Online Edition for Part no. 01 40 2 964 571 - X/15

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 162, 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 117.
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 119.
The instrument cluster displays TRACTION
in combination with SPORT. The DSC OFF
indicator lamp lights up.
2.Engage selector lever position S.3.With the left foot, forcefully press down on
the brake.
4.Step on the accelerator pedal beyond the
resistance point at the full throttle position,
kickdown.
A flag symbol is displayed in the instrument
cluster.
5.The starting engine speed adjusts. Within
3 seconds, release the brake.
Before using Launch Control, allow the trans‐
mission to cool down for approx. 5 minutes.

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,
for example approach control warning with
light braking function. There is risk of an acci‐

SymbolMeasureSymbol lights up red: prewarning.
Brake and increase distance.
Symbol flashes red and an acoustic
signal sounds: acute warning.
You are requested to intervene by
braking or make an evasive maneu‐
ver.
Prewarning
This warning is issued, for example, 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 high differential
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
Information
WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
system limits and actively interfere if needed.◀
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, for example DSC OFF.
▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.
