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The laws of physics cannot be repealed,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. Additional steering
corrections may also be required in this driving
state.
The M Dynamic Mode is deactivated each time
the engine is started.
With the M Dynamic Mode activated, sta-
bilizing interventions are only carried out
to a reduced degree. Take action yourself, oth-
erwise there is a risk of an accident.<
To maintain vehicle stability, drive with
DSC activated and the M Dynamic Mode
deactivated whenever possible.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started.The indicator lamp stays lit: M Dynamic Mode is
activated.
The indicator lamp lights up continuously and
the DSC indicator lamp flashes: the M Dynamic
Mode is active and controls the drive and brak-
ing forces.
Activating MDM
You activate the M Dynamic Mode with the
button on the steering wheel, refer to MDrive on
page52.
With the ignition switched on you can set
MDrive on the Control Display.
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 "MDrive" and press the controller.
4.Select "DSC" and press the controller.
5.Select "M Dynamic Mode" and press the
controller.
You can also activate and deactivate the
M Dynamic Mode with the MDM button.

Deactivating MDM again
Press the button on the steering wheel or the
MDM button
* again; the MDM indicator lamp
goes out.
Deactivating DSC
To maintain vehicle stability, drive with
the system activated whenever possi-
ble.<
When rocking free or starting off from deep
snow or on loose road surfaces, it can be useful
to briefly deactivate DSC.
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 page52.
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.

Starting off
On slopes
The starting assistant enables you to start off
conveniently on slopes. The handbrake is not
required for this purpose.

Notes
Do not subject the audio device to
extreme environmental conditions, e.g.
extremely high temperatures, refer to the oper-
ating instructions of the audio device. Other-wise, the audio device can be damaged and the
resulting distraction can reduce road safety
while driving.<
Depending on the configuration of the audio
files, e.g. bit rates greater than 256 Kbit/s,
proper playback cannot always be ensured.
Connecting instructions
>The USB/audio interface supplies the con-
nected audio device with power, provided
the audio device supports this function. It is
therefore unnecessary to connect the audio
device to a socket in the vehicle during
operation.
>Do not use force when plugging the con-
nector into the USB-audio interface.
>Do not connect devices such as fans or
lamps to the USB-audio interface.
>Do not connect USB hard disks.
>Do not use the audio interface to recharge
external devices.

Wheels and tires
206 BMW recommends that you replace all tires
after 6 years at most, 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 government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics 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 con-
trolled conditions on specified government test
surfaces 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.<
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less
