is displayed with the PDC image
switched on.
The display then appears on the Control
Display as soon as PDC is automatically
activated.
The previous display automatically reap-
pears after the system is deactivated.
Limits of the system
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside your
vehicle may prevent you from hearing the
PDC signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control/
ABS Antilock Brake System
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on ABS and DSC.
The concept
ABS enhances active safety by preventing
the wheels from locking under braking.
The ABS is operational every time you start
the engine. ABS includes the functions
CBC Cornering Brake Control and EBV
Electronic Brake Force Distribution.
In case of malfunction
If the indicator lamp lights up in yel-
low, this indicates that ABS has
been deactivated in response to a
system malfunction. Conventional braking
efficiency remains available without limita-
tions. Please have the system inspected at
your BMW center.

Indicator and warning lamps for
Canadian models.
DTC Dynamic Traction Control
In special driving states, e.g. in deep snow,
DTC ensures maximum forward momen-
tum. The gain in forward momentum also
involves a reduction in driving stability.
DTC is active up to 45 mph/70 km/h.
Activating DTC
Press the DSC button briefly; the
DTC indicator lamp in the instru-
ment cluster lights up permanently.
You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
When DTC is active, DSC provides
only limited system response up to a
speed of approx. 45 mph/70 km/h. Control
intervention for stability-enhancement is
reduced.<
Deactivating DTC again
Press the DSC button again; the DTC indi-
cator lamp in the instrument cluster goes
out. DSC is available once again without
restriction.
Deactivating DSC
Press the DSC button for at least 3 sec-
onds; the DSC indicator lamp in the instru-
ment cluster lights up permanently. DSC is
deactivated.
Deactivating DSC automatically deacti-
vates DTC as well. The systems for
enhancing stability and traction are deacti-
vated, and there is no active braking inter-
vention or torque control.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To maintain optimal stability, drive
with the system on whenever possi-
ble.<
Reactivating DSC
Press the DSC button again briefly; the
indicator lamp in the instrument cluster
goes out. DSC is now activated.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Therefore, do
not reduce the additional safety margin
again by taking risks.
Do not make any modifications to the DSC
system. Never allow anyone other than
authorized professional technicians to
carry out service or repairs on the DSC sys-
tem.<
DBC Dynamic Brake Control
When you apply the brakes rapidly, this
system automatically produces the maxi-
mum braking force boost and thus helps to
achieve the shortest possible braking dis-

natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When you are driving on snow-covered
or slippery road surfaces
>If you are using a sports driving style:
slip on the drive wheels, high lateral
acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted
>When you are driving with the compact
wheel, the Flat Tire Monitor is unable to
function.
Initializing the system
Perform the initialization immediately
after correcting the inflation pressure,
after changing a tire or changing a wheel or
all wheels. A drive is necessary for this pur-
pose.<
Control Center, for principle details, refer to
page 16:
1.Before beginning driving, start the
engine, but do not drive off
2.Open the menu
3.Select "Vehicle settings" and press the
controller
4.Select "FTM" and press the controller
5.Select "Set tire pressure" and press the
controller
6.Select "Yes" and press the controller
7.Drive off.
The message "Initializing" is displayed.It takes a few minutes before the Flat Tire
Monitor can detect and report a flat tire.
After the initialization is completed, the
message "Active" is displayed.
If a flat tire is detected during initialization,
a message appears on the Control Display.
When driving with snow chains or
with the compact wheel, do not initial-
ize the system.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in red and a simulta-
neous message appears on the
Control Display. In addition, an acoustic
signal sounds.
Please note any supplementary information
that appears on the Control Display. You
can find more information on the Check
Control starting on page 68.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW center.<
3.Replace the damaged wheel, refer to
Changing a tire on page 187.
Vehicles with run-flat tires:
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
edges of the run-flat tires, inflation
pressure loss can not usually be recog-
nized from the outside, refer to Run-flat
tires on page 175.<
2.To continue driving, comply with the
instructions for driving with damaged

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front pas-
senger
2Head airbags in front and rear
3Side airbags in front and rear
Protective effect
The front airbags help protect the driver
and front passenger by responding to fron-
tal impacts in which safety belts alone can-
not provide adequate restraint. When
needed, the head and side airbags help
provide protection in the event of side
impact. The relevant side airbag helps to
restrain the side upper body area. The rel-
evant head airbag helps to support the
head and provides protection against
objects entering the vehicle.
The airbags are deliberately not triggered
in every impact situation, e.g. less severe
accidents, certain roll-over conditions, or
rear-end collisions.
The rear seat side airbags may
already have been deactivated by a
BMW center. Labels in the rear door open-
ing should indicate the status of your rear
seat side airbags. If you are uncertain of
their status, or wish to have the airbags
activated or deactivated, please contact
your BMW center.<
For information on the correct sitting posi-
tion, refer to page 36.
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 reten-tion system from the vehicle. Never modify
or tamper with either the wiring or the indi-
vidual components in the airbag system.
This category includes the upholstery in the
center of the steering wheel, on the instru-
ment panel, the side trim panels on the
doors and the roof pillars along with the
sides of the headliner. Do not attempt to
remove or dismantle the steering wheel.
Do not touch the individual components
directly after the system has been trig-
gered, because there is a danger of burns.
If you note any indication of system mal-
function, if you desire to have an airbag
deactivated, or if the airbag retention sys-
tem is triggered in response to an accident,
you should always entrust all inspection,
repair and dismantling operations to your
BMW center.
Unprofessional attempts to service the sys-
tem could lead to failure in an emergency
or undesired airbag activation, either of
which could result in personal injury.
To ensure compliance with official safety
regulations, please also entrust disposal of
airbag generators to a BMW center.<
Airbag warning information is also provided
on the sun visors.
Automatic deactivation of the front
passenger airbags
Your BMW has a seat occupation detection
system. By evaluating the weight on the
front passenger's seat, the system detects
whether or not the seat is occupied by a
child in the child-restraint system or an
adult.
