absolute minimum; refill as soon as
possible. Do not drive more than
approx. 30 miles (50 km) until you do.

Indicator lamp flashes:
The system is actively regulating drive
torque and braking force.
The indicator lamp stays lit:
ASC+T has been switched off with the
button or it is defective or, the DSC has
been switched off, ADB is operational.
Please contact the nearest BMW center
in case of a malfunction.
For additional details refer to informa-
tion beginning on page 71
BMW 325xi:
DSC has been switched off manually or
there is a system malfunction. ADB-X is
operational in its standby mode. If the
warning lamp fails to go out when you
press the DSC button again, this indi-
cates a system malfunction affecting
both DSC and ADB-X.
Please consult the nearest BMW
center.

Dynamic Stability Control (DSC)
* Ð BMW 325i
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.<
Switch DSC and ADB back onPress the button again; 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repealed, even with DSC.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. This is why you should not
use the additional safety margin the
system provides as an excuse to take
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.

Dynamic Stability Control (DSC) Ð BMW 325xiThe 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
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 engine speed
and brake applications to the individual
wheels.
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 in 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 controls the drive and braking
forces.
The indicator lamp stays lit:
DSC has been switched off via the
button; 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 stability
enhancement functions described on
the left are no longer available.<
The vehicle will remain completely
operational, however, without DSC. In
the event of a malfunction, 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 switched off, and ADB-X reverts
to its maximum torque-transfer mode.
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.
To maintain vehicle stability,
always drive with the DSC
switched on whenever possible.<

Changing a wheel
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire, since this could
damage the cover.<
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated torque wrench [torque
specification: 72 lb ft (100 Nm)] at the
earliest opportunity.<
When storing a wheel in the spare tire
recess take care to avoid bending the
threaded rod.
If the original BMW light-alloy wheels
have been replaced with other light-
alloy wheels, different lug bolts may be
required.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 50 mph (80 km/h).
You can anticipate changes in vehicle
handling such as delayed braking
response, longer braking distances and
sacrifices in roadholding.
The changes in handling characteristics
will be even more pronounced if winter
tires are mounted.
Only one space-saver spare tire
may be mounted at a time. Rein-
stall wheels and tires of the same size
and specification as soon as possible.
Maintain correct tire pressures, refer to
page 24.<
Safety tires
*
Safety tires consist of self-supporting
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.Flat tireIf there is a tire failure, the red warning
lamp symbol lights up. A supplemen-
tary gong is also heard.
For additional information on Tire Pres-
sure Monitor (RDC) or Flat Tire Monitor
refer to page 78 or 80.
Reduce vehicle speed carefully to
under 50 mph (80 km/h), avoiding hard
brake applications and steering maneu-
vers.
With the safety tires, you can drive
another approx. 155 miles (250 km) to
reach a safe parking location, a service
station or the nearest BMW center.
With a low vehicle load, this can also be
considerably more than 155 miles
(250 km).
