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.
Shifting gears via sh ift paddles* on the
steering wheel
The shift paddles allow yo u to shift gears with-
out taking your hands off of the steering wheel.
> When you use the shift paddles on the
steering wheel to shif t gears in automatic
mode, the transmission switches to
manual 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: pull one of the shift paddles.
> To shift down: press one of the shift
paddles.

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: sequential mode or drive mode
> Automatic downshifting and protection
against selecting the wrong gear, even in
sequential mode
> Launch Control acceleration assistant, refer
to page 58
> Automatic double de-clutch
System limitations
This transmission is equipped with an over-
heating protection system that protects the
clutches against extremely high loads.

situations: >
Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.
> When the vehicle stops, the transmission
automatically shifts down to first gear.
> Shortly before the ve hicle slows down to
below the minimum speed of the gear cur-
rently engaged, the transmission automati-
cally shifts down without requiring your

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, arrow 1, 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
reduced 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, arrow 3.
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
Cruise control is not de activated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the st ored speed is achieved
again and maintained.

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, hi gh 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 syst em while snow chains
are attached. <
iDrive, for operating principle refer to page 16.1.
"Vehicle Info"
2. "Vehicle status"
3. "Reset"
4. Start the engine - do not drive away.
5. Start the initializat ion using "Reset".
6. Start to drive.
The initialization is completed during the trip.
The initialization is comp leted 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 page 195, the stan-
dard equipment by design, do not continue
driving. 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. <
