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 or automatic
operation, sequential mode or drive mode

Selection between different drive pro-
grams, Drivelogic, refer to page

Shift Lights, refer to page

Automatic downshifting and protection
against selecting the wrong gear even in
sequential mode

Launch Control, refer to page

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

Engage a drive position.

Briefly tap the accelerator.

The vehicle rolls at the minimum speed.

Do not press the brake continuously as
this may cause the transmission to over-

heat.

Deactivating

Brake the vehicle to a stop to deactivate the
Low Speed Assistant.
