76 signal tone sounds. The display appears on the
Control Display as soon as PDC is activated.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstacles always remains with
the driver. Even when sensors are provided,
there is a blind spot in which objects can no
longer be detected. The system is also subject
to the physical limits that apply to all forms of
ultrasonic measurement, such as those
encountered with tow bars and trailer cou-
plings, or thin and wedge-shaped objects etc.
Low objects already displayed, e. g. curbs, can
also disappear from the detection area of the
sensors again before or after a continuous tone
already sounds. Higher, protruding objects, e.g.
ledges, cannot be detected. For this reason,
drive with care; otherwise, there is a danger of
personal injury or property damage.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme 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. For information on safe braking, refer to
page109.
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.
Brake assistant
When you apply the brakes rapidly, this system
produces maximum braking force boosting and
thus helps to achieve the shortest possible
braking distance during full braking maneuvers.
This system exploits all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC optimizes vehicle stability and traction. It
also detects unstable driving states such as
understeering and oversteering, and helps
keep the vehicle on course within the physical
limits by reducing the engine output and by
braking at the wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,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
safety margin further by taking risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started.
The indicator lamp flashes: DSC con-
trols the drive forces and brake forces.
The indicator lamp stays lit: DSC is deactivated.
M Dynamic Mode MDM
The M Dynamic Mode is a mode of the DSC
Dynamic Stability Control. It enables driving
with greater longitudinal and lateral accelera-
tion on dry road surfaces, however with limited
vehicle stability. The system does not provide
stabilizing intervention by reducing the engine
output and braking at the wheels until the abso-
lute driving limit is reached. Steering correc-
tions by the driver may also be required in this
driving state.

Technology for comfort, convenience and safety
78 Press the DSC OFF button; the DSC indicator
lamp lights up continuously. DSC and MDM are
deactivated.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
Manual transmission
*:
Press and hold the MDM button.
Under unfavorable traction conditions, the
engine output may be briefly reduced even
when DSC is deactivated.
Reactivating DSC
Press the DSC OFF button; the indicator lamp
in the instrument cluster goes out.
You can also activate and deactivate DSC with
the button on the steering wheel, refer to
MDrive on page50.
Manual transmission
*:
Press the MDM button.
Malfunction in driving-stability control
systems
The warning lamp for the brake system
lights up yellow, together with the indi-
cator lamps for ABS, DSC and Tire
Pressure Monitor or Flat Tire Monitor.
A message appears on the Control Dis-
play. The driving stability control sys-
tems have failed. While you may con-
tinue, you should remember to proceed
cautiously and drive defensively while
avoiding full brake applications. The
Tire Pressure Monitor or the Flat Tire Monitor is
also malfunctioning. Have the system checked
as soon as possible.Display of the previously described
malfunction in Canadian models.
The DSC warning lamp lights up. A
malfunction has occurred in DSC
including MDM. The stability mainte-
nance functions are no longer available. The
vehicle remains operational. Have the system
checked as soon as possible.
The brake system warning lamp lights
up yellow. A message appears on the
Control Display. The brake assistant is
defective. Have the system checked as soon as
possible.

malfunction in Canadian models.
Starting off
On slopes
The drive-off assistant enables you to start off
conveniently on slopes. The parking brake is
not required for this purpose.
1.Hold the vehicle with the brake.
2.Release the brake and begin to drive imme-
diately.
After releasing the brake, begin to drive
immediately; otherwise, the drive-off
assistant no longer holds the vehicle after
approx. 2 seconds and your vehicle will start to
roll backward.<
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the brake pedal or parking
brake instead. Otherwise overheating and
heavy wear can result in the area of the Sequen-
tial Manual Transmission.<
To protect the clutch of the Sequential Manual
Transmission from overheating, the starting-off

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed letter
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Z = over 150 mph/240 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transportation.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT … 1009 means that the tire was manufac-
tured in week 10 of 2009.BMW recommends replacing all tires at least
every 6 years, even if some tires may last for
10 years. This also concerns the tire of the
spare wheel
*.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half, 1γ, times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< For instance
