Dynamic Stability Control (DSC)The conceptDSC maintains 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 DTCPress the DSC button briefly; the indi-
cator 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 until the yellow indicator lamp in
the instrument cluster lights up 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 153.
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

the tire sidewall, refer to Changing a
wheel. In this case, use only Run Flat
winter tires, since no spare tire is pro-
vided in the event of a flat tire.Tire condition, tire pressureAt tread depths below approx. 3/16 in /
4 mm, winter tires display a perceptible
decrease in their ability to cope with
winter driving conditions, and should be
replaced in the interest of safety.
Comply with the specified tire inflation
pressures — and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult any
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
225/40 R 18
245/40 R 17
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 94. OverviewControlsMaintenanceRepairsDataIndex

Towing the vehicle with the front
axle raisedVehicles with automatic transmission:
1. Towing speed: maximum 45 mph /
70 km/h
2. Towing distance: maximum
90 miles/150 km.
Vehicles with sequential manual gear-
box SMG:
While the ignition is on, move the selec-
tor lever to position N, then turn off the
ignition.Towing eyeletThe screw-in towing eyelet is stored in
the onboard tool kit; be sure that it
remains in the vehicle at all times. It can
be attached at the front or rear of the
vehicle. It should not be used to pull a
vehicle out of deep snow, mud, sand,
etc.
Always observe all applicable towing
laws and regulations.
Access to tow socketsFront:
Press out the cover panel with a screw-
driver inserted in the recess at the top.
Rear:
Press out the cover panel with a screw-
driver inserted in the recess at the top.
Use only the towing eyelet sup-
plied with the vehicle and screw it
in firmly until it stops. Use the towing
eyelet for towing on paved roads only. If
you do not follow these instructions, the
towing eyelet could be torn out and
vehicle damage could occur.
Never attach tie-down hooks, chains,
straps, or tow hooks to tie rods, control
arms, or any other part of the vehicle
suspension, as severe damage to these
components will occur, possibly lead-
ing to accidents.<
