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 windshield The 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 Coolant temperature 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 199.
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. To check the
coolant level: refer to page 147.460de082
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
preceding driving conditions.
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

The conceptThe PDC assists you when you back
into a parking space. A signal warns
you of the distance to an obstacle. To
do this, four ultrasonic sensors in the
rear bumper measure the distance to
the nearest object. The range for the
sensors located at both rear corners
ends approx. 2 ft (60 cm) behind the
bumpers. The two center sensors
cover a distance of approx. 4.9 ft
(1.50 meters).
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in posi-
tion 2. PDC is deactivated when you
shift back out of reverse.
Acoustical signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the
intervals between the tones become
shorter. A continuous tone indicates
the presence of an object less than 1 ft
(30 cm) away.
The warning signal is canceled after
approx. three seconds if the distance to
the obstacle remains constant during
this time (if you are moving parallel to
a wall, for instance).
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please refer the problem to your
BMW center.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical limits of ultra-
sonic measurement, as occurs with tow
bars and trailer couplings, and in the
vicinity of thin and painted objects.
Certain sources of sound, such as a
loud radio, could drown the PDC signal
tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effec-
tively.
Do not subject the sensors to high-
pressure washers for a prolonged
period of time. Always maintain a
distance of more than 4 in (10 cm).<

ASC+TThe conceptThese systems enhance 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
normally without ASC+T.
Please consult your BMW center in the
event of a malfunction. Refer to
pages 21 and 22.
Deactivating the ASC+T Press the button; the indicator lamp
comes on and stays on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
In the following exceptional situations,
it may be effective to deactivate the
ASC+T or DSC 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 127.
To maintain vehicle stability, drive
with the ASC+T activated when-
ever possible.<46cus044

ASC+T DSC*Reactivating 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 details concerning
ASC+T, please refer to the chapter
"Advanced Technology" on page 189.
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 keeping the car on a
steady course by reducing the RPMs
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 123.
The ADB (Automatic Differential
Braking) copies the function of conven-
tional differential and transverse lock
through brake intervention, and
increases traction 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 in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 21, 22.
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 operational.
ADB control intervention is not indi-
cated.
The indicator and the brake
warning lamps will remain on
the continuously:
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. Refer to page 21, 22.

DSC*Switch DSC off/activate ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC has been switched; ADB is opera-
tional.
In the following exceptional circum-
stances, it may be effective to deacti-
vate 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.
Refer also to page 128.
The gain in traction is achieved by a
reduction in stabilizing intervention.46cus045
Switch DSC and ADB off>Hold the DSC switch down for at
least 3 seconds. The indicator lamp
and the yellow brake warning lamps
will remain on continuously.
In this case, no interventions to
increase stability and traction for engine
and brakes are carried out.
To maintain vehicle stability,
always drive with DSC switched
on as often as possible.<
Switch DSC and ADB on againPress 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 will not carry out any stabi-
lizing 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.<
For additional details concerning DSC,
please refer to the chapter "Advanced
technology" on page 189.

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 . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation. The "6 o'clock" setting is recom-
mended as a normal setting (refer also
to the illustration and overview on
page 96).
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 78.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner 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.

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.
