handles on the driver's and front passen-
ger's doors

unlocked using the lock buttons or door han-
dles. In addition, if the remote control is used,
the welcome lamps, interior lamps and the

rior lamps come on.

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

3.Press the start/stop button.The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
To stop the starting procedure: press the start/
stop button again.

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.
