a downshift that would cause the engine to
overrev will not be executed by the system. The
gear selected is briefly displayed in the instru-
ment cluster, followed by the gear actually
in use.
Shifting gears via shift paddles* on the
steering wheel
The shift paddles allow you to shift gears with-
out taking your hands off the steering wheel.
>When you use the shift paddles on the
steering wheel to shift gears in automatic
mode, the transmission switches to man-
ual mode.
>If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode.
If the selector lever is in the M/S gear
plane, manual mode remains active.<
>To shift up: press one of the shift paddles
back, arrow 1.
>To shift down: press one of the shift pad-
dles forward, arrow 2.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The
gear selected is briefly displayed in the instru-
ment cluster, followed by the gear actually
in use.
Overriding selector lever lock
Should the selector lever refuse to move out of
position P although the button on the selector
lever is pressed, the selector lever lock can be
overridden:
1.Unclip the sleeve of the selector lever.
2.Pull the sleeve up over the selector lever
until the sleeve is inside out.
3.Using the screwdriver from the onboard
vehicle tool kit, refer to page212, press the
red lever while moving the selector lever to
the desired position.
7-gear sport automatic
transmission with dual
clutch*
The concept
This transmission is an automated manual
transmission with two clutches and two gear-
box components in which the gears are
changed without loss of torque.
You operate the transmission using the selector
lever and two shift paddles on the steering
wheel.
It offers the following functions:
>Selection between manual and automatic
operation: manual mode or drive mode
>Automatic downshifting and protection
against selecting the wrong gear, even in
manual mode
>Launch Control acceleration assistant, refer
to page58
>Automatic double declutch

Driving
58 >To shift down: press one of the shift pad-
dles forward, arrow2.
Gears can be shifted using the shift paddles in
drive mode or in manual mode.
Gear change in manual mode:
When manual mode is active, refer to page57,
gears can be changed using the shift paddles or
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.
Manual release
1.Unclip the sleeve of the selector lever.
2.Pull the sleeve up over the selector lever
until the sleeve is inside out.
3.Insert the Allen wrench from the onboard
vehicle tool kit, refer to page212, into
the cap.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
>Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
reduc ed by up to 5 mph o r 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Interrupting the system
Tap the lever upwards or downwards, arrow3.
The displays in the speedometer change color.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you switch gears very slowly or shift
to neutral in cars with a manual trans-
mission
>When you engage selector lever position N
in cars with an automatic transmission
>When you engage transmission position N
in 7-gear sport automatic transmissions
with a dual clutch
>When you activate the DTC Dynamic Trac-
tion Control or deactivate DSC
>When DSC or ABS is intervening

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.<
