Automatic Stability Control plus Traction (ASC+T)*The conceptASC+T optimizes vehicle stability and
traction, especially when you are start-
ing off, accelerating or when going
through curves.
ASC+T is ready each time you start the
engine.
ASC+T contains the Automatic Differ-
ential Brake (ADB) and Cornering Brake
Control (CBC) functions.
Additional information on ASC+T is
found in the "Technology" brochure.Indicator lamp
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: ASC+T is
actively controlling drive torque and
braking intervention
>The indicator lamp stays lit: ASC+T
has been switched off with the but-
ton; ADB is operational. ADB control
intervention is not indicated.
The indicator and the brake
warning lamps will remain on
continuously yellow:
The ASC+T and ADB have been
switched off manually or there is
a system malfunction.
You can still drive the vehicle as normal
without ASC+T.
In the event of a fault, please consult
your BMW center.

Switching off the
ASC+T/activating the ADBPress the ASC button briefly; the indi-
cator lamp comes on and stays on.
ASC+T has been switched off; ADB is
operational.
In the following rare situations, it may
be effective to activate the ADB for a
brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability,
always drive with the ASC+T acti-
vated whenever possible.<

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.
Additional information on DSC is found
in the "Technology" brochure.Indicator lamp
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 and the brake
warning lamps will remain on
continuously 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.

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.

Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sures.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure chart on page 25
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press the button until the yellow indi-
cator lamp in the instrument cluster
lights up. After a little while, the indi-
cator lamp will go out by itself
4. After a few minutes' driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference and
from that point on, can detect and
report a flat tire.
To activate/deactivate the systemThe Flat Tire Monitor automatically
assumes operation whenever you turn
the ignition key to position 2. Unless
manually deactivated, it is always on
during normal vehicle operation.
To deactivate the system: press the
button, the yellow indicator lamp comes
on.
To activate the system: press the but-
ton again, the indicator lamp goes out.
You should deactivate the system
before driving with snow chains, as the
chains can generate spurious warnings
and/or prevent the system from detect-
ing actual pressure loss.

Tire condition, tire pressureAt tread depths below approx.
3/16 in/4 mm, winter tires display a per-
ceptible 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 18245/40 R 17

Towing the vehicleTowing eyeletThe screw-in towing eyelet is stored in
the onboard tool kit; be sure that it
remains in the vehicle at all times. It is
designed for installation in the tow
sockets located at the front and rear of
the vehicle, and is intended for towing
on paved road surfaces only. The tow-
ing eyelet should not be used to pull a
vehicle out of deep snow, mud, sand,
etc. Always observe all applicable tow-
ing 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.
Make sure the towing eyelet is
firmly screwed all the way in, oth-
erwise the thread could be damaged.
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.<
