Washer/Wiper system1 Intermittent mode or rain
sensor
*
Intermittent mode:
You can use rotary dial 6 to select from
four wipe intervals.
In addition, the wipe interval is varied
automatically depending on road
speed.
Rain sensor:
The rain sensor is positioned on the
windshield, directly ahead of the inte-
rior rearview mirror. When the rain
sensor is activated, the windshield
wiper is controlled automatically,
depending on the degree of wetness on
the windshield (in both snow and rain).
You do not have to be concerned with
switching the windshield wiper on or off
or adjusting the wipe interval between 46cde095
intermittent and full wipe. Instead, you
can concentrate fully on the traffic
conditions. This is especially important
under adverse weather conditions.
To activate the rain sensor:
From ignition key position 1 and up, you
can move the lever to position 1. The
wipers travel once across the wind-
shield, regardless of the weather.
You can leave the lever permanently in
position 1. It is then only necessary to
activate the rain sensor from ignition
key position 1 and up. To do this,
>turn rotary dial 6 briefly or
>use cleaning windshield 5.
To adjust the sensitivity of the rain
sensor:
Turn rotary dial 6.
Deactivating the rain sensor:
Put lever in position 0.
Turn the rain sensor off when
passing through an automatic car
wash. Failure to do so could result in
damage caused by undesired wiper
activation.<
2 Normal wiper speedWhen the vehicle is stationary, the
wipers switch automatically to intermit-
tent wipe (not on vehicles with rain
sensor).3 Fast wiper speedWhen the vehicle is stationary, the
wipers operate at normal speed (not
on vehicles with rain sensor).5 Cleaning windshieldThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
If you pull the lever only briefly, the
system sprays washer fluid onto the
windshield without activating the
wipers.

Fuel gauge Temperature gauge Service Interval Display When you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel remaining in
the fuel tank.
For fuel tank capacity, refer to page 187.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), there may be slight fluctua-
tions of the needle.
Fill the fuel tank well before it is
empty. Driving to the last drop of
fuel can result in damage to the engine
and/or the catalytic converter.<462us020
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on while operating
the vehicle: the engine is overheated.
Stop and switch the engine off immedi-
ately and allow it to cool down.Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions. Checking coolant
level: refer to page 137.460de082
Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the distance remaining
before the next scheduled service.
The computer bases its calculations of
the remaining distance on the previous
driving style.
A flashing message and a "Ð" in front of
the number mean that the service
interval has already been exceeded by
the distance shown on the display.
Please contact your BMW center for an
appointment.46cus006

ASC+T DSC
*
Reactivating 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" on page 175.
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 car on a steady
course by reducing the engine spped
and brake applications to the individual
wheels.
The DSC is operational every time you
start the engine. DSC contains the
functions of ADB and CBC, refer to
page 116.
The ADB (automatic differential braking)
copies the function of conventional
differential and transverse lock through
brake intervention, and increases trac-
tion whenever conditions merit, e. g.
when driving on snow-covered roads.
If the DSC is switched off the ADB will
still be in ready mode.
Indicator lamp
The indicator lamp on the instru-
ment panel will go out shortly
after the ignition has been
started. Refer to pages 21 and 22.
If the indicator lamp flashes:
ASC+T or DSC control the drive and
braking forces.
The indicator lamp stays lit:
DSC has been switched off via the
button; ADB is operational.
ADB intervention not indicated.
The indicator lamp and the
brake warning lamp will light up
continously:
The DSC, ADB and DBC have
been turned off with the switch
or are defective.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please see your
BMW center. Refer to pages 21 and 22.

Air conditionerAir supply
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In posi-
tion 0, the blower 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 72.
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
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. 417(+56). 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.

Automatic recirculated air control
(AUC)
If there are unpleasant odors or
pollutants in the outside air, you
can temporarily block the air supply
from the outside. 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 supply as
required. The system then recircu-
lates the air already within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle.
>Right-hand indicator lamp on: the
supply 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
