ASC+TThe conceptThis systems enhances driving stability
and traction, especially when you are
just starting off, accelerating or in
curves.
ASC+T recognizes the danger present
in traction loss and will increase driving
stability and traction by reducing the
engine's output, and if necessary, by
applying the brakes to the rear wheels.
ASC+T is available as soon as the
engine starts up.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
ASC+T controls the drive and braking
forces.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the
button. Consequently, interventions to
increase driving stability (as described
in the preceding column) are not avail-
able. You can still drive the vehicle
perfectly well without ASC+T.
Please consult your BMW center in the
event of a fault, refer to pages 21
and 22.
Deactivate the ASC+T Press the button; the indicator lamp
comes on and stays on.
The illustration shows the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
In the following rare situations, it may
be effective to deactivate the ASC+T
for a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
>When driving with snow chains.
Refer also to page 121.
To maintain vehicle stability,
always drive with the ASC+T
activated whenever possible.<460de312

ASC+TReactivate 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repealed, even with ASC+T. It will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. This is why you should not
use the additional safety margin the
system provides as an excuse to take
risks.<
For additional informations concerning
ASC+T, please refer to "Advanced
Technology" on page 173.

DSC
* Ð BMW 325i
Deactivate DSC and ADBHold the DSC switch down for at least
3 seconds. The indicator and the yellow
brake warning lamps will remain on the
entire time.
In this case, no interventions to
increase stability and traction for engine
and brakes are carried out.
To maintain vehicle stability,
always drive with the DSC on
whenever 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.
Whenever the ADB is activated, the
DSC is switched off and will not
perform any stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
For additional information concerning
DSC, please refer to the chapter
"Advanced technology" on page 173.

Air conditioner1 Air onto the windshield and onto the
side windows
2 Air flow for the upper body
The side rotary dials allow you to
open and close the air supply through
an infinitely-variable range, while the
levers change the airflow direction.
The center rotary dial controls the
temperature of the air as it flows out.

Air conditionerAir supply
You can select fan speeds
from 1 to 4. The greater the air
supply, the more effective the
heating and ventilation are. In
position 0, the fan and the heater are
switched off. By using position 0, you
can totally block the interior ventilation
outlets by pressing the button for the
recirculated-air mode.
Temperature
In order to increase the
temperature of the passenger
compartment, turn it to the
right (red). Temperature regu-
lation will keep the interior temperature
you have selected constant.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . You can also
make all intermediate settings. In the
setting, there is a low flow of air onto
the windows to keep them free of
condensation. The "6 o'clock" setting is
recommended as a normal setting (refer
also to the illustration and overview on
page 90).
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 70.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield 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 the windows from
fogging up.
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
You can respond to unpleasant
external odors by temporarily
blocking the outside air. The system
then recirculates the air already within
the vehicle.
If the windows fog over in the
recirculated air mode, switch the
recirculated air off and increase the air
supply as required.<

Air supply

By pressing the left or right half
of the button, you can vary the
air supply. By doing this, you switch off
the automatic control for the air supply.
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioner are
switched off, and the air supply stops.
You can reactivate the system by
pressing any button of the automatic
climate control.
Defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner

fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner system is switched

Depending on the weather, the wind-
shield may fog over briefly when the

tioner off when outside air temperatures
are below approx. +41 7 (+5 6). This

Automatic recirculated air control
(AUC)
You can respond to unpleasant
external odors by temporarily
blocking the outside air. The system
then recirculates the air already within
the vehicle. By repeated actuation of
the button, you can select one of three
different operation modes.
>Indicator lamps off: fresh air flows
into the vehicle.
>Left-hand indicator lamp on Ð AUC
mode: the system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates the air already within the vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle.
>Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply as
required. When the rear window defroster
is turned on, the indicator lamp
comes on; refer to page 70.
