ation. All gears for forward travel are activated
automatically.
R Reverse Select only when the vehicle is stationary.
N Neutral
The vehicle may roll. Use in automatic car
washes, for example.
P Park
Select only when the vehicle is stationary. The
drive wheels are blocked.
Before exiting the vehicle, make sure that se‐
lector lever position P is set. Otherwise, the ve‐
hicle may begin to move.
Kickdown
Kickdown is used to achieve maximum driving
performance. Step on the accelerator pedal be‐
yond the resistance point at the full throttle po‐
sition.
Engaging selector lever positions
General information To prevent the vehicle from creeping after you
select a gear, maintain pressure on the brake
pedal until you are ready to start.
The selector lever can only be taken out of se‐
lector lever position P if the ignition is on or the
engine is running.
With the vehicle stationary, depress the brake
pedal before shifting out of selector lever posi‐
tion P or N; otherwise, the shift block will not be
deactivated and the shift command will not be
executed.
Releasing the selector lever lock A lock prevents the inadvertent switching to se‐
lector lever position R or the inadvertent
change from selector lever position P.
Releasing the lock: press unlock button on the
front of the selector lever, see arrow.

Activating the M/S manual mode1.Press the selector lever to the left out of se‐
lector lever position D.2.Push the selector lever forward or back‐
ward.
Manual mode M/S becomes active and the gear
is changed.
The engaged gear is displayed in the instru‐
ment cluster, for example, M1.
If the situation requires, the Steptronic trans‐
mission continues to shift automatically.
Example: once maximum engine speed is at‐
tained, M/S manual mode is automatically up‐
shifted as needed.
Switching to manual mode
▷To shift down: press the selector lever for‐
ward.▷To shift up: pull the selector lever rear‐
wards.
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 currently se‐
lected gear.
Manual mode M/S: prevent automatic
upshifting
Once a particular engine speed is attained, M/S manual mode is automatically upshifted as
needed.
For vehicles with Steptronic Sport transmission,
automatic shift operations are not performed if
one of the following conditions is met:
▷DSC is deactivated.▷TRACTION is activated.
In addition, there is no downshifting for kick‐
down.
With the respective transmission version, the
lowest possible gear can be selected by simul‐
taneously operating the kickdown and the left
shift paddles. This is not possible, when switch‐
ing briefly via the shift paddles from selector
lever position D to manual mode M/S.
Ending the sport program/manual mode
Push the selector lever to the right.
D is displayed in the instrument cluster.
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.▷The lowest possible gear can be selected by
pulling and holding the left shift paddles.
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 switches to manual mode tempo‐
rarily in selector lever position D and perma‐
nently in selector lever position S.
In selector lever position D, after conservative
driving for a certain amount of time in manual
mode 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.

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, engage the parking brake forcefully to
prevent the vehicle 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 208, press the
yellow release lever downward, see 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.
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.

General information Depending on the vehicle's features and coun‐
try version of the vehicle, the gear shift indica‐
tor is active in the manual mode of the Step‐
tronic transmission and with manual

Speed limit detection
The concept
Speed limit detection
Speed limit detection shows the current maxi‐
mum permitted speed in the instrument clus‐
ter. The camera at the base of the interior mir‐
ror detects traffic signs at the edge of the road
as well as variable overhead sign posts. Traffic
signs with extra symbols for wet road condi‐
tions, etc. are also detected and compared with
the vehicle's onboard data, such as for the rain
sensor, and will be displayed depending on the
situation.
With the navigation system, the system takes
into account the information stored in the navi‐
gation data and also displays speed limits pres‐
ent on routes without signs.
Without a navigation system, the system is sub‐
ject to limitations imposed by technology. Traf‐
fic signs with speed limitations are detected
and displayed only. Speed limitations due to
entering or exiting towns, highway signs, etc.
are not displayed. Speed limits with extra text
characters are always displayed.
Information
Speed limits when towing a trailer are not
shown.
