Transporting children safelyChild seat securityAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child
restraint systems.
Information pertaining to this is located
in the immediate vicinity of the buckle
latch of each safety belt.462us014
Lock the safety beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child restraint system. The
retraction mechanism is now locked.
The belt cannot be extracted further.
Always comply with the installation
instructions provided by the manufac-
turer of the child restraint system.
Unlock the safety beltRelease the safety belt, remove the
child's seat and pull the safety belt out
to its end position on the belt retractor.

ASC+T The conceptThis system enhances driving stability
and traction, especially when you are
just starting off, accelerating or on
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, 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 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. However, you can still drive the
vehicle perfectly well without ASC+T.
Please consult your BMW center in the
event of a malfunction, refer to
pages 21, 22.
Deactivating the ASC+TPress the button; the indicator lamp
comes on and stays on.
The illustration shows the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
In the following rare situations, it may
be advisable to deactivate the ASC+T
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 122.
To maintain vehicle stability,
always drive with the ASC+T
switched on whenever possible.<460de312

DSC
* Ð BMW 320i, 325i, 330i
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 keep the car on a steady
course by reducing the engine spped
and brake applications to the individual
wheels.
The DSC is operational every time you
start the engine. DSC contains the
functions of ADB and CBC, refer to
page 119.
The ADB (automatic differential braking)
copies the function of conventional
differential and transverse lock through
brake intervention, and increases trac-
tion 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 on the instru-
ment panel will go out shortly
after the ignition has been
started. Refer to pages 21, 22.
If the indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC has been switched off by the
button; ADB is operational.
ADB intervention is not indicated.
The indicator lamp and the
brake warning lamp stay lit:
DSC, ADB and DBC have been
switched off via the button or
are defective.
Indicator and warning lamps for
Canadian models.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please see your
BMW center. Refer to pages 21, 22.
Switch off the DSC/activate the
ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
The DSC has been switched off; ADB is
operational.
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 on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>or when driving with snow chains.
Refer also to page 122.
The gain in traction is achieved by a
reduction in stabilizing intervention.460de313

DSC
* Ð BMW 320i, 325i, 330i
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 the
entire time.
In this case, no interventions to
increase stability and traction for engine
and brakes are carried out.
To maintain vehicle stability,
always drive with the DSC on
whenever possible.<
Switch the DSC and ADB back onPress 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.
Whenever the ADB has been activated,
the DSC is switched off and will not
perform any stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform work on the
DSC.<
For additional details concerning DSC,
please refer to the chapter "Advanced
technology" on page 179.

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
