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.<

OverviewControlsMaintenanceRepairsDataIndex
Correct sitting posture SeatsFor relaxed and fatigue-free driving you
should select a sitting position that
reflects your personal requirements.
Correct posture combines with safety
belts and airbags to enhance occupant
safety in the event of an accident. To
ensure that the vehicle's safety systems
provide you with optimal protection, we
request that you direct your careful
attention to the following section.
For supplementary information on
transporting children, refer to page 52. Sitting correctly with airbags
Always maintain an adequate
distance between yourself and the
airbags. Always hold the steering wheel
by the rim to keep any chance of injury
to hands or arms to an absolute
minimum should the airbag be
deployed. Never allow any objects,
individuals or animals to obstruct the
areas between passengers and airbags.
Never use the front airbag's cover as a
storage tray or support for objects of
any kind. Never allow front passengers
to rest their feet or legs on the airbag
cover.<
For airbag locations and additional
information on airbags refer to page 49.
Safe with safety belts
Never allow more than one person
to wear a single safety belt. Never
allow infants or small children to ride in
a passenger's lap. Avoid twisting the
belt while routing it firmly across the
hips and shoulder, wear it as snugly
against your body as possible. Do not
allow the belt to rest against hard or
fragile objects. Do not route the belt
across your neck, or run it across sharp
edges. Be sure that the belt does not
become caught or jammed. Avoid
wearing bulky clothing and pull on the
lap belt periodically to retension it over
your shoulders. In the event of a frontal
impact, a loose lap belt could slide over
your hips, leading to abdominal
injury. In addition, the safety belt's
restraint effectiveness is reduced if it is
worn loosely. Expectant mothers
should always wear their safety belts,
taking care to position the lap belt
against the lower hips, where it will not
exert pressure against the abdominal
area.<
For information on using the safety
belts refer to page 45.
When adjusting your seat, always
observe the following precautions
Never try to adjust your seat while
operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident. Never
ride with the backrest reclined to an
extreme horizontal angle (important for
front passengers to remember). Keep
the backrest relatively upright to mini-
mize the risk of sliding under the safety
belt and sustaining injury in an acci-
dent.<

DSC
* Ð BMW 320i, 325i, 330i
Switch DSC off/activate ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is deactivated; ADB is operational.
In the following rare situations, it may
prove useful to deactivate the ADB for a
brief 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.
Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.
Switch the DSC and ADB offHold the DSC button down for at least
3 seconds. The indicator and the yellow
brake warning lamps will remain on
continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC
switched on whenever possible. lamp or the indicator lamps will go out.
The laws of physics cannot be
repealed, even with DSC. 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.
When ADB is in its standby mode, DSC
is deactivated; DSC does not intervene
to enhance vehicle stability under these
conditions.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

Driving notes Antilock Brake System
Brakes: do not drive with your foot
resting on the brake pedal. Even
light but consistent pedal pressure can
lead to high temperatures, brake wear
and possibly even brake failure.
Aquaplaning: when driving on wet or
slushy roads, reduce vehicle speed. If
you do not, a wedge of water may form
between the tires and the road surface.
This phenomenon can lead to partial or
complete loss of contact between the
tires and road surface, vehicle control
and braking ability.
Driving through water: do not drive
through water on the road if it is deeper
than 1 ft (30 cm), and then only at
walking speed. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.
Rear tray: never use it to store heavy or
hard objects, as otherwise occupants
could be injured during braking maneu-
vers.
Clothes hooks: when hanging clothing
from the hooks, be sure that they will
not obstruct the driver's vision. Do not
hang heavy objects on the hooks. If you
do so, they could cause personal injury
during braking or evasive maneuvers.<
The conceptThe Antilock Brake System (ABS) keeps
the wheels from locking during braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum pedal pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.

Tire replacementunder the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel than the
minimum required by law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.< Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Tread wear 200
Traction AA
Temperature A
Do not use retreaded tires, since
driving safety may be impaired.
This is due to the possible variations in
casing structures and, in some cases,
to their extreme age, which can lead to
a decrease in their durability.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 4101 indicates that the tire was
manufactured in week 41 of the year
2001.
Although tires may have a theoretical
service life of up to 10 years, BMW
strongly recommends that you replace
all tires after an absolute maximum of
6 years.
Safety tires
*
Safety tires consists of self-contained
tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of
pressure drop and driving remains
possible to a restricted degree. The
vehicle is equipped with Tire Pressure
Monitor (RDC) or Flat Tire Monitor,
which indicate a flat tire.
For additional information on Tire Pres-
sure Monitor (RDC) or Flat Tire Monitor
refer to pages 78 or 80.
Safety tires are only possible in
conjunction with Tire Pressure
Monitor (RDC) or Flat Tire Monitor.<

110n
Wheel and tire combinationsThe right choice
Never mount wheels and tires that
have not been specifically
approved by BMW for use on your
particular model. Although other wheels
and tires may theoretically have the
same dimensions, variations in factors
such as manufacturing tolerances can
result in contact between tire and body-
work, ultimately leading to serious acci-
dents. BMW can not evaluate all tires
and wheels on the market, and is thus
unable to guarantee that the vehicle will
continue to perform safely if unap-
proved tires and/or wheels are
mounted.<
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, ATC, ASC+T/DSC and
ADB/ADB-X/DBC.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for
example, remount the approved wheel
and tire combination as soon as
possible.<

Brake fluidWarning lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 17.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor adding brake fluid or for deter-
mining and correcting the cause of
brake fluid loss, consult your BMW
center. Your BMW center is familiar
with the specifications for factory-
approved brake fluids (DOT 4).
Brake fluid loss results in extended
pedal travel. Refer to the information on
page 106.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years at a
BMW center, refer to page 67 and to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in original container and in a location
which is out of reach of children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<
