signal sounds (ice warning). The
temperature display appears automati-
cally and flashes for 8 seconds.
The warning is repeated whenever the
temperature has reached at least
+43 7 (+6 6) and then drops to
+37.5 7 (+3 6) again.
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.5 7 (+3 6),
on bridges or shaded road surfaces, for
instance.< 367us712

ASC+T Dynamic Stability Control (DSC)*Reactivate the ASC+TPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.<
For additional details concerning
ASC+T, please refer to the chapter,
"Advanced technology," page 165.
The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, helps keep the vehicle on a
steady course by reducing the engine
speed and brake applications to the
individual wheels.
The DSC is operational every time you
start the engine. DSC includes the
functions of ADB and CBC, refer to
page 102.
The ADB (Automatic Differential
Braking) copies the function of conven-
tional differential and transverse locks
through brake intervention, and
increases traction whenever conditions
merit, e. g. when driving on snow-
covered roads.
If the DSC is deactivated the ADB is in
ready mode.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to page 22.
The indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC has been switched off via the
button; ADB is in ready mode.
ADB control intervention is not indi-
cated.
The indicator lamp and the
brake warning lamp remain on:
The DSC, ADB and DBC have
been switched off via the button
or are defective.
The vehicle will remain completely
operational, however without DSC. In
the event of a fault, please see your
BMW center.

Dynamic Stability Control (DSC)*Switch off DSC/activate ADBPress the DSC switch (arrow) Ð the indi-
cator lamp comes on and remains on.
DSC has been switched off; ADB is in
ready mode.
In the following exceptional circum-
stances, it may be effective to activate
the ADB for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>When driving with snow chains.367de739
Switch off DSC and ADBHold the DSC switch down for at least
3 seconds. The indicator lamp and the
red warning lamp for the brake
hydraulic system remain on.
In this case, no interventions to
increase stability and traction for engine
and brakes are carried out.
To maintain vehicle stability, drive
with the DSC switched on when-
ever possible.<
Reactivate DSC and ADBPress the button again; the indicator
lamp or the indicator lamps will go out.
The laws of physics cannot be
repealed, even with DSC. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.
The DSC is deactivated and will not
carry out any stabilizing intervention
when the ADB is in ready mode.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
You will find additional details
concerning DSC in the chapter
"Advanced technology" on page 165.

Heating and ventilation/Air conditioner
*
Air distribution
You can direct the flow of air
onto the windows , toward
the upper body and into the
footwell . All intermediate settings
are possible. In position , a small
volume of air is directed onto the
windows in order to keep them free of
condensation.
A "6 o'clock" position is recommended
as the normal operating setting.
Temperature
In order to increase the temper-
ature of the passenger compart-
ment, turn to the right (red). For
rapid heating, turn completely to the
right. Then select an interior tempera-
ture which is pleasant for you.
Air supply
You can select blower speeds
from 1 to 4. Both heating and
ventilation become more effec-
tive as the air supply rate is increased.
In position 0, the blower and the heater
are switched off.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð warmed
again when the air conditioner system
is switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. 41 7(+5 6). This will
help to prevent condensation from
forming on the windows.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
If there are unpleasant odors in
the outside air, you can tempo-
rarily block the supply of the
incoming air. The system then recircu-
lates the air currently within the vehicle.
If the windows fog over in the
recirculated-air mode, switch this
mode off and increase the air supply as
required.<
