7-gear Sport automatic
transmission with dual clutch
The concept
This transmission is an automated manual
transmission with two clutches and two gearbox
components in which the gears are changed
without loss of torque.
The transmission is operated using the selector
lever and two shift paddles on the steering
wheel.
Functions:
▷Choice of manual or automatic operation:
manual mode or drive mode.▷Automatic downshifting and protection
against selecting the wrong gear, even in
manual mode.▷Acceleration assistant, Launch Control, re‐
fer to page 58.▷Automatic throttle blip.
System limits
This transmission is equipped with an overheat‐
ing protection system that protects the clutches
against extremely high loads.
The indicator lamp lights up yellow if
the transmission becomes too warm.
Avoid high engine loads and driving off
frequently.
If the transmission overheats, the indicator lamp
lights up red and power flow to the engine is in‐
terrupted. You can only continue driving after
the transmission has cooled down.
Avoid driving off frequently with high accelera‐
tion and do not hold the vehicle on inclines by
depressing the accelerator lightly; otherwise,
the transmission may overheat.

Sport program
This position is recommended for a perform‐
ance-oriented driving style.
The gear position and the engaged gear are dis‐
played in the instrument cluster, for instance S1.
Manual mode
When you press the selector lever forward or
backward, or when you pull one of the shift pad‐
dles, manual mode is activated and the gear is
changed.
The gear position and the engaged gear are dis‐
played in the instrument cluster, for instance
M1.
The transmission provides assistance in the fol‐
lowing situations:
▷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 would cause the
engine to overrev will not be executed by the
system.▷When the vehicle stops, the transmission
automatically shifts down to first gear.▷Shortly before the vehicle slows down to be‐
low the minimum speed of the gear currently
engaged, the transmission automatically
shifts down without requiring your interven‐
tion.Shifting down rapidly: even in manual mode, you
can skip several gears to achieve optimal accel‐
eration. Do so by pressing the accelerator past
the resistance point.
Changing to drive mode
Push the selector lever to the right.
Shifting gears via the selector lever
In manual mode:▷To shift up, pull back the selector lever.▷To shift down, push it forward.
Shifting gears using the shift paddles
on the steering wheel
The shift paddles allow you to shift gears with‐
out taking your hands off the steering wheel.
You do not need to raise your foot from the ac‐
celerator when doing so.
▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
Gears can be shifted using the shift paddles in
drive mode or in manual mode.
Gear change in manual mode
When manual mode is active, refer to page 57,
gears can be changed using the shift paddles or

cient, the forward gears are changed again au‐
tomatically.
Launch Control
Launch Control enables you to drive off with an
optimal vehicle acceleration on a high grip road
surface.
Do not use Launch Control too often
Do not use Launch Control too often, as
the higher loads on the vehicle lead to premature
component wear.◀

pressed all the way down.6.The transmission shifts up automatically as
long as the accelerator is pressed all the way
down.
Launch Control only becomes available again
after a certain distance has been driven.
Launch Control can only be used after the
break-in phase, refer to page 108.
To maintain driving stability, activate DSC
whenever possible.
Manually releasing and engaging the
transmission lock
If a power failure occurs, e.g., if the battery is
discharged or disconnected, the transmission
lock must be released manually, otherwise the
rear wheels are blocked and the vehicle cannot
be towed.
Release the transmission lock manually for tow‐
ing only and set the parking brake beforehand to
prevent the vehicle from rolling. After parking

▷Do not hang pieces of clothing, such as jack‐
ets, over the backrests.▷Make sure that passengers do not lean their
heads against the side airbag; otherwise, se‐
rious injuries could result if the airbag sud‐
denly deployed.▷Do not remove the airbag restraint system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system. This
also applies to the covers of the steering
wheel, the dashboard and the seats.◀
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in injury.◀
Warning notices and information about the air‐
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
The system determines whether the front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body. The front and side
airbags on the front passenger side are acti‐
vated or deactivated accordingly by the system.
The indicator lamp above the interior rearview
mirror shows the current status of the passen‐
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.
Passenger feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, the front
passenger airbags may not function properly.◀
Child restraint fixing system in the front
passenger seat
Before transporting a child on the passenger
seat, read the safety and operating instructions
under Transporting children safely, refer to
page 43.◀
Malfunction of the automatic
deactivation system
The front passenger airbags may be deactivated
if adolescents and adults sit in certain positions;
the indicator lamp for the front passenger air‐
bags comes on. In this case, change the sitting
position so that the front passenger airbags are
activated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, do not transport
the passenger in the vehicle.
To make sure that occupation of the seat cush‐
ion can be detected correctly:▷Do not attach seat covers, seat cushion pad‐
ding, ball mats or other items to the passen‐
ger seat unless they are specifically recom‐
mended by BMW.▷Do not place any objects on the front pas‐
senger seat.▷Do not place objects under the seat that
could press against the seat from below.

The indicator lamp for the front passenger air‐
bags indicates the operating status of the front
and side airbags on the front passenger side de‐
pending on the seat occupation. The indicator
lamp shows whether the passenger airbags are
activated or deactivated.▷The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is de‐
tected on the seat or the seat is empty. The
front and side airbags on the front passen‐
ger side are not activated. Most child seats
are detected by the system, Especially the
child seats required by NHTSA at the time
that the vehicle was manufactured. After in‐
stalling a child seat, make sure that the indi‐
cator lamp for the front passenger airbags
lights up. This indicates that the child seat
has been detected and the front passenger
airbags are not activated.▷The indicator lamp does not light up when,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat. The front and front passenger air‐
bags on the front passenger side are acti‐
vated.
Operational readiness of airbag system
When the ignition, refer to page 46, is switched
on, the warning lamp comes on briefly to indi‐
cate that the entire airbag system and the belt
tensioners are operational.
Airbag system malfunction▷The warning lamp does not light up when the
ignition is switched on.▷Warning lamp remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not function
as intended even if a sufficiently severe accident
occurs.◀
Flat Tire Monitor FTM
The concept
The system detects a pressure loss in a tire on
the basis of speed differences between the in‐
dividual wheels during a trip.
In the event of pressure loss, the rolling circum‐
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.Seite 75SafetyControls75
