Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. There is a malfunction in the sys-
tem. Have the system checked as soon as pos-
sible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially in curves.
The suspension will be noticeably softer and
the vehicle will display a greater tendency to tilt
during cornering and in crosswinds.
If a message stating that you should stop is
shown on the Control Display, stop at a suitable
location and switch off the engine as soon as
possible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system. Do
not continue driving, but instead contact your
BMW center.<
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains
*.<
iDrive, for principle details, refer to page16.

7.Select "Yes" and press the controller.
8.Start driving.
The message "Initializing..." is displayed.
The initialization is completed during driving.
Then the message "Status: FTM active"
appears on the Control Display again.
Indication of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.Stop driving if the vehicle is no longer
equipped with run-flat tires, as it was
when it came from the factory, refer to
page188. Continued driving after a flat tire
can result in serious accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on run-flat
tires, based on the following guide values:
>With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
>With full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tances and altered natural steering charac-
teristics.
If unusual vibrations or loud noises occur
while the vehicle is being driven, this can
indicate final failure of the damaged tire.
Reduce speed and stop at a suitable loca-
tion as soon as possible; otherwise, pieces
of the tire could become detached and
cause an accident. Do not continue driving,
but instead contact your BMW center.<

Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
At low speeds, e.g. in a town or when parking,
the steering angle of the wheels is increased,
i.e. the steering becomes very direct.
In the higher speed range, on the other hand,
the steering angle is reduced more and more.
This improves the handling capability of your
BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page86.
Malfunction
The warning lamp lights up and a mes-
sage appears on the Control Display. The active steering is no longer operational. At
low speed, larger steering wheel movements
are required, while the vehicle reacts more sen-
sitively to steering wheel movements in the
higher road speed range. The stability-promot-
ing intervention can also be deactivated. Pro-
ceed cautiously and drive defensively. Have the
system checked.

Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please follow the adjustment instructions on
page47.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of a side impact. The relevant side air-
bag supports the side upper body area. The
head airbag supports the head. The knee airbag
protects the legs from colliding with the cockpit.
The airbags are deliberately not triggered in
every impact situation, e. g. less severe acci-
dents or rear-end collisions.
For details on the correct seat position, refer to
page47.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Do not modify or
tamper with either the wiring or the individual
components in the airbag system.This category
includes the upholstery in the center of the
steering wheel, on the instrument panel, the
side trim panels on the doors and on the Coupe,
the roof pillars along with the sides of the head-
liner. Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation, or
triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators carried out only by a BMW cen-
ter or a workshop that works according to BMW
repair procedures with appropriately trained
personnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury. also provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The system
correspondingly activates or deactivates the
front, knee and side airbag on the front passen-
ger side.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags below.<
Before transporting a child in the front
passenger seat, read the safety informa-
tion and follow the instructions under Trans-
porting children safely, refer to page56.
The front, knee and side airbag on the front pas-
senger side can be deactivated for teenagers
and adults in certain seat positions; the indica-
tor lamp for the front passenger airbags lights
up when this occurs. In these cases, change the
seat position so that the front passenger air-
bags are activated and the indicator lamp goes
out. If the desired status cannot be produced by
changing the seat position, transport the corre-
sponding person in the rear seat.
Do not fit seat covers, seat cushion padding,
beaded mats or other items onto the front pas-
senger seat unless they are specifically recom-
mended by BMW. Do not place objects under
the seat which could press against the seat
from below. Otherwise a correct evaluation of
the occupied seat surface cannot be ensured.<

Operating state of front passenger
airbags
The illustration here shows a possible arrange-
ment in the Coupe. With some vehicle equip-
ment packages or in the Convertible, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front,
knee and side airbag on the front passenger
side depending on whether the seat is occu-
pied. The indicator lamp shows whether the
front passenger airbags are activated or deacti-
vated.
>The indicator lamp lights up when a child in
a child restraint system intended for the
purpose is properly detected on the seat.
The front, knee and side airbag on the front
passenger side are deactivated.
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
The front, knee and side airbag on the front
passenger side are activated.
>The indicator lamp does not light up when
the seat is empty.
But the front, knee and side airbag on the
front passenger side are still deactivated.
Operational readiness of airbag system
With the ignition lock at radio readiness or
higher, refer to page58, the warning lamp lights
up briefly, indicating the operational readiness
of the entire airbag system and the safety belt
tensioners.
Airbag system malfunction
>Warning lamp does not light up as of radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction; otherwise,
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<
Convertible: rollover
protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal or transverse axis, or loss of ground
contact. The rollover bars located behind the
rear head restraints are deployed within frac-
tions of a second.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion system ensures that all vehicle occupants
have the necessary headroom.
Always keep the path of movement of the
rollover protection system clear.
In less severe accidents, you are protected by
the fastened safety belt and, depending on the
severity of the accident, the belt tensioner and
the multistage airbag restraint system.<

only be performed at a BMW center.
Unprofessional attempts to service the system
can lead to failure or malfunction.For a system check and to ensure long-term
functioning, you must comply with the mainte-
nance intervals of the service requirements,
refer to page77.<
