Dynamic Stability Control (DSC)The conceptDSC supports vehicle stability, even in
critical driving situations.
DSC is operational every time you start
the engine.
DSC contains the Dynamic Traction
Control (DTC) and Cornering Brake
Control (CBC) functions.Indicator lamps
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to page 19.
>The indicator lamp flashes: DSC is
actively controlling drive torque and
braking intervention
>The indicator lamp stays lit: DSC has
been switched off with the button;
DTC and DBC are operational. DTC
control intervention is not indicated.
The indicator lamp and the
brake warning lamp continu-
ously light up in yellow:
The DSC, DTC and DBC have
been switched off manually or
there is a system malfunction.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center.
Indicator and warning lamps for
Canadian models.
Deactivating the DSC/activating
the DTCTap the DSC button; the indicator lamp
comes on and stays on.
DSC is deactivated; DTC is operational.
In the following rare situations, it may
prove useful to activate the DTC for a
brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.

System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to, but no more than 10 seconds,
until the indicator lamp in the instru-
ment cluster lights up in yellow for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
When driving with snow chains or
a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. This
visual alert is accompanied by
an acoustic warning signal.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 157.
After replacing the damaged tire, initial-
ize the system.
Vehicles with Run Flat tires:
1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a speed of 50 mph /
80 km/h

tire center, preferably your BMW cen-
ter. Observe any country-specific regu-
lations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-approved radial belt tires
are matched to your vehicle and pro-
vide optimum safety and driving com-
fort when used properly.Run Flat tiresIf your vehicle is equipped with Run Flat
tires, refer to Run Flat tires, use only
these tires since no spare wheel is
available in the event of a flat.Special characteristics of winter
tiresBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires with
M+S designation provide better winter
traction than summer tires, they gener-
ally do not achieve the full performance
of winter tires.
Run Flat tires:
If your vehicle is equipped with Run Flat
tires, refer to Run Flat tires, please note
the following: when mounting new tires
or replacing summer tires with winter tires, or vice versa, use only Run Flat
tires since no spare wheel is available
in the event of a flat. Your BMW center
wil be glad to advise you.
Observing speed ratings:
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW center
will be glad to assist you with the
required professional knowledge and
specialized equipment.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel. Do not
exceed the maximum tire inflation pres-
sures specified on the tire sidewall.
Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult your
BMW center for details. BMW recom-
mends using only these approved fine-
link snow chains. Use them in pairs on
either summer or winter tires, but only
on both rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.
You cannot mount snow chains with the
following tires:
>225/50 R 16
>225/45 R 17
>245/40 R 17
>225/40 R 18
>255/35 R 18.
Do not initialize the Flat Tire Moni-
tor after mounting snow chains to
the tires.
When driving with snow chains, it may
be useful to turn off the DSC for a short
time, refer to page 92.<
