M dual clutch transmission
with Drivelogic*
The concept
The M dual clutch transmission with Drivelogic
is an automated manual transmission with two
clutches and a partial transmission in which an
electro-hydraulic system takes over clutch
action and shifting.
With the M dual clutch transmission, gears are
changed without interruption of the traction
force.
The M dual clutch transmission is operated
using the selector lever and two shift paddles
on the steering wheel.
The transmission offers you the following func-
tions:
>Selection between manual and automatic
operation: sequential mode or drive mode
>Selection between different drive pro-
grams, Drivelogic, refer to page52
>Shift Lights, refer to page52
>Automatic downshifting and protection
against selecting the wrong gear even in
sequential mode
>Launch Control, refer to page53
>Automatic throttle blip
>Low Speed Assistant
System limitations
The M dual clutch transmission is equipped
with an overheating protection system that pro-
tects the clutch against extreme loads.
The indicator lamp lights up yellow
when the transmission becomes too
warm. Avoid high engine loads and
driving off frequently. When the transmission is
overheated, the indicator lamp lights up red and
the fuel supply to the engine is cut off. You can-not continue driving until the transmission has
cooled down.
Avoid driving off frequently with high accelera-
tion and do not hold the vehicle on inclines by
pressing lightly on the accelerator while letting
the clutch slip, as this may cause the transmis-
sion to overheat.
In traffic congestion or at very low speeds, use
the Low Speed Assistant, refer to the informa-
tion below.
Low Speed Assistant
The Low Speed Assistant supports you when
driving at very low speeds: the vehicle moves at
walking speed and automatically controls the
engine speed. You can also use the Low Speed
Assistant when rocking the vehicle out of deep
snow. To do so, shift between reverse gear and
the forward position without pressing the brake.
Activating
1.Engage a drive position.
2.Briefly tap the accelerator.
The vehicle rolls at the minimum speed. Do not
press the brake continuously as this may cause
the transmission to overheat.
Deactivating
Brake the vehicle to a stop to deactivate the
Low Speed Assistant.
Selector lever positions
>R: reverse gear

Driving
50 >Β: middle position
>N: neutral
>+: shift up manually
>–: shift down manually
>D/S: change between drive mode and
sequential mode
The selector lever locks in position R. In other
transmission positions, it stays in the middle
position; the gear positions are engaged by
pressing lightly in the desired direction.
The gear position currently engaged is indi-
cated by LEDs in the selector lever.
Shiftlock
When the vehicle is stationary, press the brake
pedal before shifting out of N, otherwise the
desired gear will not be engaged.
R Reverse
Select this only when the vehicle is stationary.
N Neutral
If the driving situation demands, e.g. when
downshifting on a slippery road, the M dual
clutch transmission automatically disengages
and engages the clutch, i.e. it is not necessary
to manually engage the neutral position.
N engages when you open the driver's
door while the engine is running, your
safety belt is not fastened and you activate nei-
ther the brake pedal nor the accelerator. To
drive off after closing the driver's door and fas-
tening your safety belt, move the selector lever
to position N first and then to the desired drive
position.<
N remains engaged even after the engine
is switched off if you leave the remote
control in the ignition lock. Use this function in
an automatic car wash, for example, refer to
page48.<
S sequential mode
Shift up or down using the shift paddles or the
selector lever. You do not need to lift your foot
off the accelerator when doing so.Shift from sequential mode to drive mode:
Press the selector lever to the right in the D/S
direction.
Shift back to sequential mode: shift using the
shift paddles or the selector lever, or press the
selector level to the right in the D/S direction
again.
On a level road, you can drive off in second gear,
e.g. on slippery roads.
The M dual clutch transmission assists you in
the following 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 vehicle slows down to
below the minimum speed of the gear cur-
rently engaged, the transmission automati-
cally shifts down without requiring your
intervention.
Rapid downshifting: in sequential mode, you
can skip several gears to achieve optimal accel-
eration. To do so, press the accelerator past the
resistance point and pull the left shift paddle
once or press the selector lever forward once.
D drive mode
In drive mode, all forward gears are shifted auto-
matically.
Shift from drive mode to sequential mode: shift
using the shift paddles or the selector lever, or
press the selector level to the right in the D/S
direction.
Shift back to drive mode: press the selector
lever to the right in the D/S direction again.
Kick-down: to accelerate rapidly, e.g. when
passing, press the accelerator down past the
resistance point. This provides maximum accel-
eration.

automatically while the engine is running or the
ignition is switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Therefore, keep it away from ignition
sources and only store it in the closed original
container that is kept out of reach of children,
otherwise there is a risk of personal injury.
Comply with the instructions on the con-
tainer.<
Washer fluid filler neck
Only refill washer fluid when the engine is
cool to avoid contact with hot engine
parts. Otherwise, fluid spills constitute a fire
hazard and a risk to personal safety.<
All washer nozzles are supplied with washer
fluid by the same reservoir.
Fill with water and, if required, with a washer
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 4.8USquarts/4.5liters.
Cruise control
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g., snow, rain, ice
or loose surfaces. Otherwise you could lose
control of the vehicle and cause an accident as a
result.<
