vated engine starts up automatically in the fol‐
lowing situations:▷Excessive warming of the car's interior
when the cooling function is switched on.▷The steering wheel is turned.▷Steptronic transmission: change from selec‐
tor lever position D to R, N or M/S.▷Steptronic transmission: change from selec‐
tor lever position P to R, N, D or M/S.▷The vehicle begins rolling.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷The vehicle battery charge is very low.▷Excessive cooling of the car's interior when
the heating is switched on.▷Manual transmission: low brake vacuum
pressure; this can occur, e.g., if the brake
pedal is depressed a number of times in
succession.

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 maximum 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, the kickdown is deactivated.
With the respective transmission version, the
lowest possible gear can be selected by simul‐
taneously operating the kickdown and the left
shift paddle. However, this effect is not pro‐
duced via the shift paddles when switching
briefly from D to manual mode.
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.▷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.
Displays in the instrument cluster The selector lever position is dis‐
played, e.g.: 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:

sition.
Steptronic Sport transmission: Launch
Control
The concept
Launch Control enables optimum acceleration
on surfaces with good traction.
Hints Component wear
Do not use Launch Control too often; oth‐
erwise, this may result in premature wear of
components due to the high stress placed on
the vehicle. ◀
Do not use Launch Control during the break-in,
refer to page 134, 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 94.
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 96.
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.
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.

Flashing and then continuously illuminated: no
flat tire or loss of tire inflation pressure can be
detected.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.▷TPM could not conclude the reset: perform
the reset of the system again.▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.
For additional information, refer to Tire Pres‐
sure Monitor, refer to page 81.
