Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamps for DSC in the instrument cluster
light up. Dynamic Traction Control DTC and
DSC have been simultaneously deactivated.
Stabilizing and drive-output promoting actions
are no longer executed.
In the same way as with a differential interlock,
even if DSC is deactivated, brake actions are
still performed on the rear axle to enhance drive
output if the drive wheels experience a signifi-
cant loss of traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; the indicator lamps in
the instrument cluster go out.
For better control
If the indicator lamp flashes:
DSC controls the drive forces and
brake forces.
If the indicator lamps are on:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
In the same way as with a differential interlock,
even if DTC is activated, brake actions are still
performed on the rear axle to enhance drive output if the drive wheels experience a signifi-
cant loss of traction.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button; the indicator lamps for DTC in
the instrument cluster come on.
For better control
If the indicator lamp flashes:
DTC controls the drive forces and
brake forces.
If the indicator lamps are on:
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
xDrive*
xDrive is your BMW's four-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the driving situation and road
conditions.

Technology for driving comfort and safety
92 The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Depending on vehicle load,
the car may roll backwards a little during this
time span. Drive off without delay after releas-
ing the brake. Otherwise, the drive-off assistant
will no longer hold the car in place after approx.
2 seconds and the car will start to roll back-
wards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
If a tire loses pressure, its rolling radius
changes, and this in turn alters the speed of
rotation. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
iDrive, for operating principle refer to page16.

Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufac-
turer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page90.<
