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
page27.
1.Depress the brake.
2.Depress the clutch and shift to neutral.
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.

Drivelogic
Remote control in the ignition lock or, with con-
venient access, inside the vehicle, refer to

1.Depress the brake.
2.Press the start/stop button.
The engine starts with the selector level in any
position. Driving off: with the engine running,
move the selector level from the middle position
Β in the desired direction.
Every time you start the engine, sequential
mode is activated in program S3 if you lightly
press the selector lever to the right to position
D/S with the brake pedal depressed.
Switching off the engine
Always take the remote control with you
when you leave the vehicle.
When parking, apply the parking brake force-
fully, otherwise the vehicle could begin to roll.<
Manual transmission
1.With the car at a standstill, press the start/
stop button.
2.Shift into first gear or reverse.
3.Forcefully apply the parking brake.
4.Removing the remote control from the igni-
tion lock, refer to page46.

engine, you are notified visually and acous-
tically.

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 page52
>Shift Lights, refer to page52
>Automatic downshifting and protection
against selecting the wrong gear even in
sequential mode
>Launch Control, refer to page53
>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.

ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch hot exhaust pipes, e. g.
when loading the cargo bay, otherwise there is a
risk of burn injuries.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page113.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise greater clutch
wear will result.<
For more information about the drive-off assis-
tant, refer to page69.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system.
M dual clutch transmission: never drive
with the transmission in neutral or with
the engine switched off; otherwise, engine
braking action will not be present or there will be
no power assistance to the brakes or steering.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
engine braking action will not be present or
there will be no power assistance to the brakes
or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
