Preventing automatic engine stop
with M double clutch transmission
Principle To enable the vehicle to move off particularly
swiftly, for example at a junction, the automatic
engine stop can be actively prevented.
Preventing automatic engine stop
using the brake pedal
The engine stop can be actively prevented
within a second of the vehicle coming to a
standstill:▷Press the brake pedal down firmly as soon
as the vehicle has come to a standstill.▷Then immediately brake again with normal
braking force.
Manually deactivating/activating the
system
Using the button
Press the button.
▷LED illuminates: Auto Start Stop function
is deactivated.
During an automatic engine stop, the en‐
gine is started.
The engine can be started or stopped only
by means of the start/stop button.▷LED goes out: Auto Start Stop function is
activated.Parking the vehicle during automatic
engine stop
With automatic engine stop, the vehicle can be
parked safely, for example in order to leave it.1.Press the start/stop button. The ignition is
switched off. The Auto Start Stop function
is deactivated.
P is engaged automatically.2.Apply the parking brake.
Start engine as usual, using the start/stop but‐
ton.
Automatic deactivation
In certain situations the Auto Start Stop func‐
tion is deactivated automatically for safety's
sake, for example if the absence of the driver is
detected.
Malfunction
The Auto Start Stop function no longer shuts
down the engine automatically. A Check Con‐
trol message is displayed. It is possible to keep
driving. Have the system checked.
Parking brake
Applying The lever engages itself after pulling up.
The indicator light illuminates red. The
parking brake is engaged.
If it must be used while driving by way of ex‐
ception, slightly engage the parking brake
while pressing and holding the button.
To avoid corrosion and one-sided braking ef‐
fect, slightly pull on the parking brake from
time to time when moving away, if traffic condi‐
tions allow.
The brake lights do not illuminate when the
parking brake is applied.

Reverse gear
Engage this position only when the vehicle is
stationary.
To overcome the resistance of the selector
lever move in a dynamic movement towards
the left and engage the reverse gear.
M double clutch
transmission with Drivelogic
General The M double clutch transmission with Drive‐
logic is an automated manual gearbox with two
clutches and partial gears, by which the gears
are changed without interrupting traction.
It is operated using the selector lever or two
paddles on the steering wheel.
Functions▷Drive mode or sequential mode.▷Various drive programs, Drivelogic.▷Shift Lights, see page 96▷Automatic downshift and protection
against shifting even in sequential mode.▷Launch Control.▷Low Speed Assistant.
Selector lever, selector lever position
Overview
▷R: reverse.▷N: neutral, idling.▷ Centre position, forward setting.▷+: manually change up.▷-: manually change down.▷D/S: change between drive mode and se‐
quential mode.
Engaging selector lever position
Press the brake pedal and push or pull the se‐
lector lever in the appropriate direction.
As soon as the selector lever is released, it re‐
turns to the central position. The selector lever
engages into position R.
The engaged selector lever position is shown
in the instrument cluster and on the selector
lever.
After a selector lever position has been en‐
gaged, the vehicle can roll away when the
brake is released, for example on a downhill
slope. As a result, drive away immediately after
releasing the brake.
Use the Low Speed Assistant when manoeu‐
vring or in stop-and-go traffic.
Low Speed Assistant
Principle
The Low Speed Assistant provides support at
very low speeds. The vehicle drives at walking
pace.
Can also be used for rocking out on snow. To
do that, shift between reverse gear and for‐
ward position, without apply the brakes.
Note ATTENTION
The transmission can overhead when us‐
ing the function and depressing the brake
pedal at the same time for an extended time.
Danger of damage to property. Do not brake
for an extended time when using the func‐
tion.◀

Activating1.Engage a drive position.2.Briefly tap on the accelerator pedal.
The vehicle rolls at minimum speed.
This is possible in 1st and 2nd gear and in re‐
verse.
Deactivating
Brake the vehicle until it comes to a stop.
Flashing display on selector lever of
double clutch transmission
In some situations, the actually engaged gear‐
box setting may be different from the selector
lever position, and the display in the selector
lever flashes.
In these cases, refer to the display in the in‐
strument cluster, see page 75.
D Drive mode
In drive mode, all forward gears are automati‐ cally changed.
Kick-down: for maximum acceleration, for ex‐
ample, when overtaking. To do that, depress
the accelerator pedal beyond the resistance
point.
Change to sequential mode: shift using the
shift paddles or push the selector lever in the
D/S direction.
S sequential mode Change up or change down using the shift
paddle or selector lever without coming off the
gas.
▷Shortly before a minimum speed depend‐
ing on the gear, it automatically down‐
shifts.▷The gears are only shifted up or down with
the appropriate engine speed and road
speed.
For example, there is no downshift at too
high an engine speed.▷Kick-down: by operating the kick-down
and the left shift paddle or selector lever at
the same time, you can change down to
the lowest possible gear.▷Driving off is possible even in 2nd gear on a
level carriageway, for example, when it is
smooth.
To change to Drive mode: press selector lever
in the D/S direction.
R Reverse Engage this position only when the vehicle is
stationary.
For rocking out, even up to 10 km/h, approxi‐
mately 6 mph is possible. To do that, shift be‐
tween forward and reverse gear without apply‐
ing the brakes.
N Neutral, idling Select this in a car wash, for example. The ve‐
hicle will then be able to move, see page 208.
P Park The driven wheels are locked.
Transmission position P is engaged automati‐
cally:
▷After stopping the engine in the radio
ready state, see page 65, or ignition off,

Launch Control
Principle
Launch Control allows optimum acceleration
when driving off on a non-slip road surface.
General
Using Launch Control leads to preliminary component wear, as this function represents a
very heavy load for the vehicle.
Do not use Launch Control when running in,
see page 162.
Requirements
Launch Control is available with an engine at
operating temperature, so after an uninterrup‐
ted drive of at least 10 km, approximately
6 miles.
To start with Launch Control, do not engage
the steering wheel.
Activating Launch Control1.Deactivate Dynamic Stability Control, see
page 124.2.Select sequential mode with gear 1 and
drive program 3.3.With the engine running, depress the brake
with the left foot.4.Depress accelerator pedal fully.
The engine speed when driving off is regu‐
lated.
The flag symbol appears in the instrument
cluster.5.Using the Cruise Control, change the en‐
gine speed when driving off by 500 rpm.6.Release brake, vehicle accelerates. Con‐
tinue to press accelerator pedal.
Upshifting happens automatically as long
as the accelerator pedal is fully depressed.
Launch Control is only available again after a
certain distance has been travelled.
System limits
This gearbox has overheat protection, which
protects the clutch against extreme loads.
▷Indicator light illuminates yellow:
gearbox too hot.
Avoid high engine load and fre‐
quent driving off.▷Indicator light illuminates red: gearbox
overheated.Seite 77DrivingControls77
