Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
ABS is operational every time you start the
engine. Braking safely, refer to page129.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.

Self-leveling suspension*
Malfunction
The warning lamp for self-leveling
suspension lights up yellow and a
message is shown on the Control
Display. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at
the front, and possibly also on one side – rear
left compared to rear right –, proceed to the
nearest BMW Sports Activity Vehicle Center or
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel. Drive with appropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving comfort may be notice-
a bly reduced. Even if the orientatio n of the vehi-
cle is normal, when a malfunction is indicated
on the display, you should proceed to the near-
est BMW Sports Activity Vehicle Center or a
workshop that works according to BMW guide-
lines and uses appropriately trained personnel.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Function requirements
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.The initialization must be repeated after
each time the tire inflation pressure is cor-
rected 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 snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains
* or with the
compact wheel
*.<
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Settings" and press the controller.
4.Select "Vehicle / Tires" and press the con-
troller.

TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Function requirements
In order to assure the reliable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious
tire damage caused by external influ-
ences.<
The system does not function properly if it has
n o t b e e n r es e t , e. g . a f l a t t i re i s re p o rt e d d e s p it e
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, e.g. a compact wheel
*, or if TPM is
temporarily interfered with by other systems or
devices which use the same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
All wheels are yellow
Flat tire or a major drop in inflation pressure in
several tires. A message appears on the Control
Display.
Gray
The system cannot detect a flat tire.
Reasons for this can be:
>TPM is being reset
>Temporary interference due to systems or
devices which use the same radio fre-
quency
>Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
Resetting finishes during driving, which can be
interrupted at any time. When driving resumes,
resetting is continued automatically. Do not
reset the system when driving with a compact
wheel
*.

98 Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and has
the required explosives licenses. Otherwise
unprofessional attempts to service the system
could lead to failure in an emergency or undes-
ired airbag triggering, either of which could
result in personal injury.<
Warnings and information on the airbags is 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 front and
side airbags on the front passenger side are
activated or deactivated accordingly by the sys-
tem.
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 in the following.<
Before transporting a child on the front
passenger seat, read the safety informa-
tion and follow the instructions under Trans-
porting children safely, refer to page55.
When teenagers and adults assume certain sit-
ting positions, this can cause the front and side
airbags to deactivate. The indicator lamp for the
front passenger airbags lights up when this
occurs. In these cases, change the sitting posi-
tion so that the front passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired status cannot be produced by changing
the sitting position, transport the correspond-
ing person on the rear seat. Do not fit seat cov-
ers, seat cushion padding, ball mats or other
items onto the front passenger seat unless they
are specifically recommended by BMW. Do not
lay objects under the seat which could press
against the seat from below. Otherwise a cor-
rect evaluation of the occupied seat surface
cannot be ensured.<
Operating state of front passenger
airbags
Depending on the vehicle's equipment, 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
and side airbags on the front passenger side
depending on the seat occupation. The indica-
tor lamp shows whether the front passenger
airbags are activated or deactivated.
>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 and side airbags on the front pas-
senger side are not activated.
Most child's seats are detected by the
system. Especially the child's seats
required by the NHTSA at the time the vehi-
cle is manufactured. After installing a child's
seat, make sure that the indicator lamp for
the front passenger airbags lights up. This
indicates that the child's seat has been
detected and the front passenger airbags
are not activated.<
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
The front and side airbags on the front pas-
senger side are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbags on the
front passenger side are not activated.
