Indicator and warning lamps Technology that monitors itself Many of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. Indicator and warning lamps
that are identified by "l" are tested for
proper functioning whenever the igni-
tion key is turned. They each light up
once for different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react to this below.
Red: stop immediately
Battery charge l
The battery is no longer being
charged. There is a malfunction
of the alternator V-belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the V-belt is defective, do not
continue driving. If you do so, the
engine could be damaged due to over-
heating. If the V-belt is defective,
increased steering effort is also
required.<
Engine oil pressure
l
Stop the vehicle and switch off
the engine immediately. Check
the engine oil and top off as required. If
the oil level is correct, please contact
the nearest BMW center.
Do not continue driving. If you do
so, the engine could be damaged
because of inadequate lubrication.<
Tire Pressure Control (RDC)
* l
In addition, an acoustic signal is
sounded: a tire failure has
occurred. Reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
brake applications. Do not oversteer.
For additional information, refer to
page 86.
Brake hydraulic system l
If the lamp comes on when the
parking brake is not engaged:

DSC Ð BMW 325xi, 330xiThe conceptDSC maintains vehicle stability, even in
critical driving situations.
The system enhances vehicle stability
during acceleration and when starting
up from a full stop, and optimizes trac-
tion as well. 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 RPMs and
brake applications to the individual
wheels.
The DSC is operational every time you
start the engine. DSC contains the
functions of ADB-X and CBC, refer to
page 119.
The ADB-X (automatic differential
braking) replaces the function of
conventional differential and transverse
lock through brake intervention, and
increases traction whenever conditions
merit, e. g. when driving on snow-
covered roads.Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21, 22.
Indicator lamp flashes:
DSC controls the drive and braking
forces.
Indicator lamp lights up permanently:
DSC has been switched off via the
button; ADB-X is operational.
ADB-X intervention is not indicated.
If the warning lamp does not go
out after pressing the DSC button
repeatedly, then both the DSC and
ADB-X are defective. Consequently,
interventions to increase driving
stability (as described in the preceding
column) are not available.<
You can drive perfectly well without
DSC. Please contact your BMW center
in the event of a fault, refer to
pages 21, 22.
Switching the DSC offPress the DSC button; the indicator
lamp comes on and stays on.
The DSC has been switched off and the
ADB-X is designed for maximum
output.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
Refer also to page 122.
To maintain vehicle stability,
always drive with the DSC on
whenever possible.<460de313

Antilock Brake System (ABS)consequences of brake applications
with inadequate clearances for safety
between vehicles, when exceeding the
speed limit, or the risks involved when
aquaplaning occurs. Responsibility for
these types of situations remains in the
hands (and at the feet) of the driver. You
should never allow the added safety of
ABS to mislead you into taking
increased risks.
Do not make any modifications to
the ABS system. Service proce-
dures on ABS are to be performed by
authorized technicians only. Cornering Brake Control (CBC) CBC is an advanced engineering devel-
opment of ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is improved
and the steering response is enhanced.In the event of a fault
If the ABS in the instrument
cluster lights up, refer to
page 22. The brake system then
reverts to conventional operation as on
vehicles without ABS. However, have
the brake system checked by your
BMW center as soon as possible. To
prevent undetected defects and cumu-
lative faults from adversely affecting the
brake system, refer any problems to
your BMW center at the earliest oppor-
tunity.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the indi-
cator lamps for ABS and
ASC+T/DSC, refer to page 21,
the entire ABS, CBC and
ASC+T/DSC control system has
failed. Continue driving
cautiously and defensively.
Avoid full brake applications. This could
cause the vehicle to lose stability and
you might no longer be able to control
it.
Have the system checked as soon as
possible by your BMW center.
CBC, ABS and ASC+T/DSC
and
ADB/ADB-X/DBC indicator and
warning lamps for Canadian
models.
Dynamic Brake Control (DBC)*DBC is included in the DSC, refer to
information beginning on page 84.
If you step on the brake rapidly, this
system automatically produces
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction,
the yellow brake warning lamp
comes on. Normal braking effi-
ciency and ABS are still fully available.
Have the system checked and repaired
at your BMW center as soon as
possible.
Please observe the section "Infor-
mation for your safety" concerning
the ABS system, which also applies to
the DSC system.<

Brake systemBrake fluid level
If the brake warning lamp
comes on and the parking brake
has been released:
The brake fluid level is too low in the
reservoir (refer to page 143).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the hydraulic circuits of the brake
system.
Brake warning lamp for Cana-
dian models.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
If the warning lamp for the brake
pads lights up:
The brake pads have reached
their minimum pad thickness. Proceed
to the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads that BMW has
approved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Airbags For protection against dampness or
moisture, treat the leather with a BMW
impregnating agent.
We recommend that you perform this
procedure twice a year on leather
exposed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains without
rubbing, but rather by dabbing with
spot remover.
If the upholstery will be exposed to
intense sunlight, or if the vehicle is to
be stored for an extended period, cover
all leather surfaces to prevent fading (or
better yet, cover the windows).
Use cleaning and car-care
products that you can obtain at
your BMW center.<
Cleaning agents can contain
substances that are dangerous or
that pose health risks. For this reason,
always comply with the warnings and
danger notices on the packaging.
Open the doors or windows on your
vehicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically
intended for this purpose.<
