Sport program and manual operation
M/S
Move selector lever from position D toward the
left into the M/S shifting slot; the Sport program
is activated. This position is recommended for a
performance-oriented driving style.
DS is displayed in the instrument cluster.
To deactivate the sport program or manual
mode M/S, move the selector lever to the right
into position D.
Shifting gears via the selector lever
Move selector lever from position D toward the
left into the M/S shifting slot:
When you press the selector lever forwards or
backwards, the manual mode is activated and
Steptronic changes gear.
The engaged gear, e.g. M1 is displayed in the
instrument cluster.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system.
The gear selected is briefly displayed in the
instrument cluster, followed again by the gear
actually in use.
Shifting gears via shift paddles* on the
steering wheel
The shift paddles allow you to shift gears
quickly since both hands can remain on the
steering wheel.>When you use the shift paddles on the
steering wheel to shift gears in automatic
mode, the transmission switches to manual
mode.
>If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode.
If the selector lever is in the M/S gear
plane, manual mode remains active.<
>To upshift, briefly pull the right shift
paddle +.
>To downshift, briefly pull the left shift pad-
dle –.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system.
The gear selected is briefly displayed in the
instrument cluster, followed again by the gear
actually in use.
Overriding selector lever lock
If the selector lever will not move out of
position P even though the ignition is switched
on, the brake is depressed, and the button on
the selector lever is pressed, the selector lever
lock can be overridden:
1.Unclip the sleeve of the selector lever.
2.Pull the sleeve up over the selector lever
until the sleeve is inside out.

Driving
62 3.Using the screwdriver from the onboard
vehicle tool kit, refer to page227, press the
red lever, see arrow, while moving the
selector lever to the desired position.
7-gear Sport automatic
transmission with double
clutch*
The concept
The 7-gear Sport automatic transmission with
double clutch is an automated manual trans-
mission with two clutches and secondary gear
sets in which the clutching and shifting is han-
dled by an electrohydraulic system.
With the 7-gear Sport automatic transmission
with double clutch, the gears are shifted without
an interruption in driving power.
You operate the 7-gear Sport automatic trans-
mission with double clutch using the selector
lever and two shift paddles on the steering
wheel.
It offers you the following functions:
>Either manual or automatic mode: sequen-
tial mode or drive mode
>Automatic downshifting and protection
against incorrect gear selection, even in
sequential mode
>Acceleration assistant, Launch Control,
refer to page66
>Automatic intermediate throttle application
System limitations
The 7-gear Sport automatic transmission with
double clutch has an overheating protection
that protects the clutch from extreme loads.
The indicator lamp lights up in yellow if
the transmission becomes too warm.
Avoid high engine loads and frequent
accelerations from zero. If the transmission is
overheated, the indicator lamp lights up in red
and the power flow to the motor is interrupted. It
is only possible to continue driving once the
transmission has cooled down.
Avoid frequent powerful accelerations from
zero 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.
Selector lever positions
P R N D M/S + –
The selector lever position and the engaged
gear are displayed, e.g. M4.
Engaging selector lever positions
>The selector lever can be moved out of
position P only with the engine running:
interlock.
>Before moving the lever away from P or N
with the vehicle stationary, first depress the
brake; otherwise, the desired shift will not
be executed: shiftlock.

Driving
64 The engaged gear, e.g. M1 is displayed in the
instrument cluster.
In the following situations, the 7-gear Sport
automatic transmission with double clutch
does the thinking for you:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that could cause the
engine to overrev will not be executed by
the system.
>At a stop, the transmission is automatically
shifted down to the first gear.
>Shortly before the speed falls below a gear-
dependent minimum speed, the transmis-
sion automatically downshifts without your
intervention.
Quick downshifting: even in sequential mode,
you can skip over several gears in order to
achieve an optimum acceleration. To do so,
depress the accelerator past the resistance
point.
To return to automatic mode, push the selector
lever to the right.
Gear shifting
Upshift or downshift using the selector lever or
the shift paddles. You do not need to lift your
foot off the accelerator when doing so.
Using the selector lever
>To upshift, pull the selector lever toward the
rear.
>To downshift, push it toward the front.
Using the shift paddles on the steering
wheel
You can also shift manually using two shift pad-
dles on the steering wheel. The shift paddles
allow you to shift gears quickly since both
hands can remain on the steering wheel.
>When you use the shift paddles on the
steering wheel to shift gears in automatic
mode, the transmission switches to manual
mode.>If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode if the selector lever is in
position D.
>To upshift, briefly pull the right shift
paddle +.
>To downshift, briefly pull the left shift pad-
dle –.
Driving dynamics control
The driving dynamics control permits you, at
the push of a button, to have your BMW react in
an even more sporty fashion when driving:
>Optimal use is made of the engine's speed
range.
>Gear changes occur more quickly.
>The engine reacts more spontaneously to
accelerator pedal movements.
Activating the system
Press the SPORT button.
The LED in the button lights up.
Deactivating the system
>Press the SPORT button again
>Switch off the engine

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 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 container.<
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.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
You can use the cruise control feature begin-
ning at approx. 20 mph/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.<

Maintaining current speed
Briefly press the lever, arrow 1, or pull it briefly,
arrow 2.
The car's current speed is stored and main-
tained. It is briefly displayed in the instrument
cluster.
If the engine braking power is insufficient on a
downhill slope, the set speed may be exceeded.
On uphill grades vehicle speed may drop if the
engine output is insufficient.

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 page118.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
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 prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions at the indi-
vidual 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
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.<
Deactivating DSC
Press the button for at least 3 seconds until the
indicator lamp for DSC OFF lights up and DSC
OFF is displayed in the instrument panel.
Dynamic Traction Control DTC and DSC have
been simultaneously deactivated. Stabilizing
and drive-output promoting actions are no
longer executed.
In the same way as with a differential interlock
*,
even if DSC is deactivated, brake actions are
still performed on the rear axle to enhance drive
output if the drive wheels experience a signifi-
cant loss of traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; the indicator lamp in the
instrument panel goes out.
For better control
If the indicator lamp flashes: the DSC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and
DSC OFF is displayed in the instrument
panel: DSC is deactivated.

Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.
whether or not the FTM is active.
1."Vehicle Info"
2."Vehicle status"
3."Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set infla-
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.
1."Vehicle Info"
2."Vehicle status"3."Reset"
4.Start the engine – do not drive away.
5.Start the initialization by selecting "Reset".
6.Start driving.
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.<
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds. There is a flat tire or a major
loss in tire pressure.
1.Reduce speed and stop the vehicle with
caution. Avoid sudden braking and steering
maneuvers.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents.<
When a flat tire is reported, the Dynamic Stabil-
ity Control DSC is activated.
Actions in the event of a flat tire
Run-flat tires
With a damaged tire, is possible to continue
driving at speeds of up to 50 mph/80 km/h.
When driving with a damaged tire:
1.Avoid sudden braking and steering maneu-
vers.
2.Do not exceed a speed of 50 mph/80 km/h.
3.At the next opportunity, check the inflation
pressure in all four tires.

Technology for driving comfort and safety
86 If the inflation pressure in all four tires is cor-
rect, the Flat Tire Monitor might not have
been initialized. The system must then be
initialized.
Possible driving distance with complete loss of
tire pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle while driving.
With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics change, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steering response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change, e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change.<
Vibrations or loud noises while driving can
indicate final failure of the tire. Reduce
your speed and bring the vehicle to a stop; oth-
erwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center.<
Tire Pressure Monitor TPM*
The concept
Check the inflation pressure in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was correct; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
>When a wheel without TPM electronics is
installed.
>Interference with TPM by other systems or
devices with the same transmission fre-
quency.
Status display
The current status of the Tire Pressure Monitor
TPM can be displayed on the Control Display,
e.g., whether or not the TPM is active.
1."Vehicle Info"
2."Vehicle status"
3."Tire Pressure Monitor - TPM"
The status is displayed.

Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
A change in the tire inflation pressure during
driving is taken into account.
A correction is only required when this is indi-
cated by the TPM.
Green wheels
The inflation pressure corresponds to the
desired state.
"TPM active" appears in the Control Display.
One wheel yellow
There is a flat tire or substantial loss of tire pres-
sure in the indicated tire.

>There is a flat tire or substantial loss of tire
pressure in several tires.
>The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
Gray wheels
The system cannot detect a puncture.
Reasons for this may be:
>TPM is being reset.
>Interference from systems or devices that
use the same radio frequency.
>Malfunction.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
1."Vehicle Info"
2."Vehicle status"3."Reset"
4.Start the engine – do not drive away.
5.Reset the inflation pressure by selecting

6.Start driving.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The resetting process
is completed automatically as you drive. On the
Control Display, the wheels are shown in green
and "Status: TPM active" is displayed.
The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
If a flat tire is detected while the system is
resetting, all tires on the Control Display
are displayed in yellow. The message "Low
tire!" is displayed.<
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.
>There is a flat tire or substantial loss of tire
pressure in the indicated wheel.
>The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers.
When a low tire pressure is reported, the
Dynamic Stability Control DSC is activated.
