Radio readiness and ignition off
All indicator and warning lamps as well as dis-
plays in the instrument cluster go out.
Starting the engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral and forcefully
apply the parking brake to prevent the car from
moving.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter.<
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
Manual transmission
Remote control in the ignition lock or, with con-
venient access, inside the vehicle, refer to

Reverse gear
Select this only when the vehicle is stationary.
When the gearshift lever is pressed to the left, a
slight resistance has to be overcome.
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 page60
>Shift Lights, refer to page61
>Automatic downshifting and protection
against selecting the wrong gear even in
sequential mode
>Launch Control, refer to page62
>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
58 >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
page56.<
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.

Driving
66 On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If engine braking power is
insufficient on a downhill grade, the stored
speed may be exceeded.
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 lightly to the
resistance 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
Accelerate slightly, increase speed steadily:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.
Accelerate strongly, increase speed in intervals
of 10:
Press the lever beyond the resistance point,
arrow 1, 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 or 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Deactivating cruise control
Tap the lever upwards or downwards, arrow3.
The displays on the speedometer disappear.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you shift or depress the clutch
>When you deactivate DSC
>When DSC or ABS is intervening
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.
Resuming a speed stored beforehand
Press the button, arrow4.
The stored speed is resumed and maintained.
When the ignition is switched off, the stored
speed value is cleared and can no longer be
called up.
