Sport automatic 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;
otherwise, this may result in premature wear of
components due to the high stress placed on
the vehicle.◀
Did not use Launch Control during the break-
in, refer to page 166, period.
To increase vehicle stability, activate DSC
again as soon as possible.
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 controlWhile the engine is running:1. Press button or select with the
Driving Dynamics Control Sport+.TRACTION is displayed in the instrument
cluster and the indicator lamp for DSC OFF
lights up.2.Engaging the transmission position S3.With the left foot, forcefully press down on
the brake.4.Press and hold down the accelerator pedal
beyond the resistance point at the full
throttle position.
A flag symbol appears 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.
Launch Control adjusts to the surrounding
conditions, e.g., wet pavement, when used
again.

vers.2.Check whether the vehicle is fitted with

is correct, it is possible that a reset was not
carried out for the Tire Pressure Monitor.

MalfunctionThe yellow warning lamp flashes andthen lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire pressure can be detected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Disturbance by systems or devices with
the same radio frequency: after leaving the
area of the disturbance, the system auto‐
matically becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the
level to trigger illumination of the TPMS low
tire pressure telltale. Your vehicle has also
been equipped with a TPMS malfunction indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning prop‐
erly. Always check the TPMS malfunction tell‐
tale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement
or alternate tires and wheels allow the TPMS
to continue to function properly.
FTM Flat Tire Monitor The conceptThe system detects a pressure loss on the ba‐sis of speed differences between the individual
wheels while driving.
In the event of a pressure loss, the diameter
and therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
The system does not measure the actual infla‐
tion pressure in the tires.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable signaling of a flat tire is not en‐Seite 102ControlsSafety102
Online Edition for Part no. 01 40 2 926 810 - X/13
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
Status display The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.
1."Vehicle Info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive away.5.Start the initialization with "Perform reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.

driving resumes.
Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with

Run-flat tires, refer to page 197, are la‐
beled with a circular symbol containing the

Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.Seite 103SafetyControls103
