the selector lever.
Gear change in drive mode
The shift paddles can be used to change gears
in drive mode as well.
Afterwards, if the shift paddles are not used for
some time and vehicle acceleration is insuffi-
cient, the forward gears are changed again
automatically.
Launch Control
Launch Control enables you to drive off with an
optimal vehicle acceleration on a high grip road
surface.
Do not use Launch Control too often, as
the higher loads on the vehicle lead to
premature component wear.<
Launch Control is available when the engine is
at operating temperature, i.e., after driving con-
tinuously for at least 6 miles/10 km.
1.With the engine running, depress the brake
pedal with your left foot.
2.Activate the SPORT+ program of the
Dynamic Driving Control, refer to page79.
3.With the vehicle stationary, activate manual
mode and select first gear.
4.Press the accelerator all the way down. The
engine speed when driving off is controlled.
A flag symbol appears in the instrument
cluster.
5.The vehicle accelerates when you release
the brake pedal. Keep the accelerator
pressed all the way down.
6.The transmission shifts up automatically as
long as the accelerator is pressed all the
way down.Launch Control only becomes available again
after a certain distance has been driven.
Launch Control can only be used after the
break-in phase, refer to page112.
To maintain driving stability, activate DSC
whenever possible.<
Manually releasing and engaging the
transmission lock
If a power failure occurs, e.g., if the battery
is discharged or disconnected or if there
is an electrical malfunction, the transmission
lock must be released manually; otherwise, the
rear wheels are blocked and the vehicle cannot
be towed.<
Release the transmission lock manually for tow-
ing only and set the parking brake beforehand
to prevent the vehicle from rolling. After parking
the vehicle, lock the transmission lock again
manually, refer to page59.

assistant will not hold the car in place after
approx. 2 seconds, the car would otherwise
start to roll backwards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period
of time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<1."Vehicle Info"
2."Vehicle status"
3."Reset"
4.Start the engine - do not drive away.
5.Start the initialization using "Reset".
6.Start to drive.
The initialization is completed during the trip.
The initialization is completed during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.
If the car is not equipped with run-flat
tires, refer to page199, the standard
equipment by design, do not continue driv-
ing. Otherwise, a severe accident could
result if you continue driving.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.<
