For your own safety

Use unleaded gasoline only. Fuels
containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight (i.e.
15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent) will
not void the applicable warranties
covering defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality (volatility, composition, addi-
tives, for example) among gasolines
offered for sale in the United States and
Canada. The use of poor-quality fuels
may result in driveability, starting and
stalling problems, especially under
certain environmental conditions, such
as high ambient temperature and high
altitude.
Should you encounter driveability prob-
lems which you suspect could be
related to the fuel you are using, we
recommend that you respond by
switching to a recognized high-quality
brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Obey all applicable safety rules when
handling gasoline.

Luggage compartment lidOpening from the inside
*
If the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is
stationary.
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, following the same precautions
as with all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
closed. Otherwise, exhaust fumes
could penetrate the interior of the
vehicle. Should it be absolutely neces-
sary to operate the vehicle with the
luggage compartment lid open:
>Close all windows. Shut the sliding/
tilt sunroof
>Sharply increase the air supply for the
air conditioning or automatic climate
control. Refer to page 85 or 88.<

Fuel gauge Temperature gauge Service Interval DisplayOnce the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For information on the fuel tank
capacity, refer to page 143.
Certain operating conditions (such as
those encountered in mountainous
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on during normal
vehicle operation: the engine has over-
heated. Shut off the engine immediately
and allow it to cool down.
For instructions on checking the
coolant level, refer to page 117.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector in normal operation.
Remaining distance to 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 OIL SERVICE or INSPEC-
TION, together with the distance
remaining in miles (kilometers) before
the next scheduled service. The
computer bases its calculations of the
remaining distance on the preceding
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

ASC+T DSC
* Ð BMW 320i, 325i, 330i
To switch ASC+T back onPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.<
The conceptThe Dynamic Stability Control (DSC)
maintains vehicle stability, even in crit-
ical 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
under- or oversteering, and, as far as is
possible within the laws of physics,
helps keeping the vehicle on a steady
course by reducing the rpms and brake
applications to the individual wheels.
DSC is operational every time you start
the engine. DSC incorporates the func-
tionality of the Automatic Differential
Brake (ADB) and the Cornering Brake
Control (CBC).
ADB relies on selective braking applica-
tions at the drive wheels to furnish the
functionality of a conventional limited-
slip differential for enhanced traction in
critical driving conditions such as those
encountered on snow-covered road
surfaces, etc.
The ADB is operational when DSC is
switched off.
Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC is actively controlling drive torque
and braking intervention.
The indicator lamp stays lit:
DSC has been switched off manually;
ADB is operational.
ADB control intervention is not indi-
cated.
The indicator and the brake
warning lamps remain on
continuously:
The DSC, ADB and Dynamic
Brake Control (DBC) have been
switched off with the button or
are defective.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center, refer to pages 18, 19.

DSC Ð BMW 325xi, 330xiThe conceptThe Dynamic Stability Control (DSC)
maintains vehicle stability, even in crit-
ical 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
under- or oversteering, and, as far as is
possible within the laws of physics,
helps keeping the vehicle 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-X and CBC.
The Automatic Differential Brake
(ADB-X) enhances traction in critical
situations (such as those encountered
on snow-covered roads) by using
selective braking intervention to replace
the limited-slip functions executed by
the differential and transfer case in
conventional drivetrains.
Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC is actively controlling drive torque
and braking intervention.
The indicator lamp stays lit:
DSC has been switched off manually;
ADB-X is operational.
ADB-X control intervention is not indi-
cated.
If the indicator lamp fails to go out
when you press the DSC button,
this indicates a malfunction in the DSC
and ADB-X systems; the system is
deactivated, and the stability enhance-
ment functions described on the left are
no longer available.<
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center, refer to pages 18, 19.
To deactivate DSCPress the DSC button briefly, the indi-
cator lamp comes on and remains lit.
DSC is now off, and ADB-X reverts to
its maximum torque-transfer mode.
Under the following special circum-
stances you may find it useful to deacti-
vate DSC manually 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 DSC acti-
vated whenever possible.<

Air conditioningAir 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
position 0, the blower and the heater
are switched off. The outside air supply
is blocked in position 0.
Temperature
In order to increase the
temperature of the passenger
compartment, turn to the right
(red). The temperature of the
incoming air is kept constant.
Air distribution
You can direct the emerging
air toward the windows ,
toward your upper body or
into the footwell . All inter-
mediate settings are possible. In the
setting, there is a low flow of air onto
the windows to keep them free of
condensation.
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
The rear window defroster auto-
matically assumes operation
within 5 minutes after the engine is
started at outside temperatures below
approx. 39 7 (+4 6).<
Air conditioning
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Switching on the air
conditioning will reduce condensation
forming on the windows.
Condensation forms during opera-
tion of the air conditioning system,
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
suspending the supply of outside air.
The system then recirculates the air
currently within the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
it off and increase the air supply as
required.<

Air conditioningDraft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the
optimum airflow rates and directions for
your personal requirements:
1 Rotary dials for infinitely-variable
opening and closing of the vent
outlets
2 Selector levers for airflow direction
3 Rotary dial 3 allows you to control the
temperature of the airflow from these
outlets as desired.
MicrofilterThe built-in microfilter removes dust
and pollen from the incoming air. Your
BMW center will replace it during
routine maintenance. A substantial
reduction in airflow indicates that the
filter needs to be replaced before
scheduled maintenance.
To defrost windows and remove
condensation1 Set the blower speed control for the
airflow rate to position 4
2 Turn the rotary temperature control
completely to the right (red)
3 Rotary control for air distribution to
position
4 Switch on the rear window defroster
to defrost the rear window.
