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.

When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do, your vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid.
Do not use the washers when the washer fluid
reservoir is empty, otherwise you will damage
the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated
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.<

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.<

Technology for driving comfort and safety
82 until "PDC" is selected and press the con-
troller.
6.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display is shown on the Control Display as
soon as PDC is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e. g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously, otherwise there is a risk of personal
injury or property damage. Loud sound sources
outside or inside the car can drown out the PDC
signal. Therefore, always drive cautiously, oth-
erwise there is a risk of personal injury or prop-
erty damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page115.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assist
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC optimizes driving stability and traction. In
addition, the system recognizes unstable driv-
ing situations such as understeering and over-
steering, and helps keep the vehicle on a safe
course within physical limits by reducing engine
power and applying the brakes on individual
wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks, as this could
result in an accident.<
M Dynamic Mode MDM*
M Dynamic Mode is a mode of the Dynamic
Stability Control DSC that permits greater lon-
gitudinal and lateral acceleration when driving
on dry surfaces, yet with reduced driving stabil-
ity. Only at the absolute limit of stability does
the system intervene to stabilize the vehicle by
reducing engine power and applying the brakes
on the wheels. In such situations, additional
