Adaptive brake assistant*
In conjunction with the active cruise control
with the stop-and-go function, the adaptive
brake assistant ensures that the brake
responds even more quickly during braking
with the brake assistant.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions in the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not restrict the additional
safety margin with a risky driving style, as other-
wise there is a risk of an accident.<
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not longer
than approx. 10 seconds. DTC Dynamic Trac-
tion Control and DSC are deactivated together.
Stabilizing and drive output promoting actions
are no longer executed. In addition, the stability
promoting intervention of the active steering
*
is deactivated, refer to page99.
A message appears on the Control Display.
Please note any supplementary information
that appears there.To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.
For better control
The indicator lamp flashes:
DSC controls the drive forces and
brake forces.
The indicator lamp lights up:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.

wheel. Do not touch the individual components
immediately after the system has been trig-
gered, because there is a danger of burns.
In the event of malfunctions, deactivation, or
triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel and has the required explosives
licenses. Otherwise unprofessional attempts to
service the system could lead to failure in an
emergency or undesired airbag triggering,
either of which could result in personal injury.<
Warnings and information on the airbags is also
provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The front and
side airbags on the front passenger side are
activated or deactivated accordingly by the sys-
tem.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following.<
Before transporting a child on the front
passenger seat, observe the safety infor-
mation and handling instructions under Trans-
porting children safely refer to page56.
The front and side airbags on the front passen-
ger side can be deactivated for teenagers and
adults in certain sitting positions; then the indi-
cator lamp for the front passenger airbags lights
up. In these cases, change the sitting position
so that the front passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired status cannot be produced by changing
the sitting position, transport the correspond-
ing person on the rear seat. Do not fit seat cov-
ers, seat cushion padding, ball mats or other
items onto the front passenger seat unless they
are specifically recommended by BMW. Do not
lay objects under the seat which could press against the seat from below. Otherwise a cor-
rect evaluation of the occupied seat surface
cannot be ensured.<
Operating state of front passenger
airbags
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica-
tor lamp shows whether the front passenger
airbags are activated or deactivated.
>The indicator lamp lights up when a child in
a child restraint system intended for the
purpose is properly detected on the seat.
The front and side airbags on the front pas-
senger side are not activated.
Most child's seats are detected by the
system. Especially the child's seats
required by the NHTSA at the time the vehicle is
manufactured. After installing a child's seat,
make sure that the indicator lamp for the front
passenger airbags lights up. This indicates that
the child's seat has been detected and the front
passenger airbags are not activated.<
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
The front and side airbags on the front pas-
senger side are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbags on the
front passenger side are not activated.

Things to remember when driving
138
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
rear backrest.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
>Do not pile objects higher than the top edge
of the backrest.
>Sports Wagon:
Use the partition net to protect the occu-pants, refer to page129. Make sure that
objects cannot penetrate through the parti-
tion net.
Wrap sharp-edged or pointed objects
which could strike the rear window while
driving.
Securing cargo
>Use the luggage net*, luggage straps, or
securing straps to hold down small and
lightweight luggage and cargo.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes
mounted in the cargo bay are used to
secure these heavy-duty cargo straps, refer
to illustration.
>Please observe the special instructions
supplied with the heavy-duty cargo straps.
Position and secure the cargo as
described above, so that it cannot endan-
ger the vehicle's occupants, for example if sud-
den braking or evasive maneuvers are neces-
sary.
Use only the lashing eyes to secure heavy-duty
cargo straps, refer to illustration, otherwise the
cargo straps could become detached or the
vehicle could be damaged.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page257, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic safety laws.
You should never transport unsecured heavy or
hard objects in the passenger compartment, as
they could fly around and pose a safety hazard
to the vehicle's occupants during abrupt brak-
ing or evasive maneuvers.<

Roof-mounted luggage rack*
A special rack system is available as an option
for your BMW. Please comply with the precau-
tions included with the installation instructions.
Mounting points
The mounting points are located in the door
openings or on the roof rails
*.
Loading roof-mounted luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
its handling and steering response.
You should therefore always remember not to
exceed the approved roof load capacity, the
approved gross vehicle weight or the axle loads
when loading the rack.
You can find the specified weights under
Weights on page257.
Distribute the roof load uniformly. The load
must not be too large in area. Always stow the
heaviest pieces on the bottom. Be sure that
adequate clearance is maintained for raising the
glass sunroof, and that objects do not project
into the opening path of the luggage compart-
ment lid/tailgate.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
during the trip.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.
