can drown out the PDC signal. Therefore,
always drive cautiously, otherwise there is a risk
of personal injury or property damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page 116.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus help s to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the ve hicle maintain a safe
course within physical lim its by reducing engine
output and through braking actions at 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The laws of physics cannot be repealed,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 reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.
<
Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamps for DSC in the instrument cluster
light up. Dynamic Traction Control DTC and
DSC have been simultaneously deactivated.
Stabilizing and drive-output promoting actions
are no longer executed.
328i, 335i: in the same way as with a differential
interlock, even if DSC is deactivated, brake
actions are still performed on the rear axle to
enhance drive output if the drive wheels experi-
ence a significant loss of traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; the indicator lamps in
the instrument cluster go out.
For better control
If the indicator lamp flashes:
DSC controls the drive forces and
brake forces.
If the indicator lamps are on:
DSC is deactivated.
Dynamic Traction Control DTC
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

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2 Head airbags
3 Side airbags in the seat backrests
Protective action
Observe the adjustment instructions on
page 41 to ensure the best possible per-
sonal protection. <
The front airbags help protect the driver and
front passenger by re sponding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restrain t. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags have been designed to not be trig-
gered in every collision situation, e.g. not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the dashboard and windows on the front
passenger side clear, i.e. do not cover with
adhesive labels or coveri ngs, and do not attach
holders such as for navigation instruments or
mobile phones.
Do not attach seat cove rs, cushions or other
objects not specifically approved for seats with
integral side airbags to the front seats. Do not
hang items of clothing such as coats or jackets
over the backrests. Do not attempt to remove the airbag retention system from the vehicle. Do
not modify the individual components of the
system or its wiring in any way. This includes
the upholstered covers
on the steering wheel,
instrument panel, seats and roof posts, as well
as the sides of the roof lining. Do not attempt to
remove or dismantle the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
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 repair
procedures of BMW with correspondingly
trained personnel and that has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesi red airbag activation,
either of which could resu lt in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
An analysis of the impr ession in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passenger are activated or
deactivated by the system accordingly.
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger ai rbags, deactivated or

Things to remember when driving
118
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
> Cover sharp edges and corners.
> For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
Sedan
Sports Wagon
> Use the partition net to protect passengers,
refer to page 107. Make sure that objects
cannot penetrate the partition net.
> Do not stack cargo hi gher than the upper
edge of the backrests.
> Place protective material around any
objects which could bump against the rear
window while the vehicle is in motion.
Securing cargo
>Secure smaller and lighter items using
retaining straps, a cargo bay net
* or draw
straps
*.
> Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes are
provided for attaching the cargo straps.
Two are located on the cargo bay
sidewalls 1, two more are on the rear cargo
bay panel 2.
Please comply with the information sup-
plied with the cargo straps.
Always position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the a pproved axle loads, refer
to page 241, as excessive loads can pose a
safety hazard, and may al so place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.

Only attach the cargo straps using the lashing
eyes shown in the illustration. Do not secure
cargo with the anchors for tether straps, refer to
page 50, otherwise these could be damaged. <
Roof-mounted luggage rack*
A special rack system is available as an option
for your BMW. Comply with the directions given
in the installation instructions.
Mounting points
The mounting points are located in the roof/
along 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
vehicle 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 applicab le data under Weights
on page 241.
The roof load must be distributed uniformly and
should not be too large in area. Heavy items
should always be placed at the bottom. Be sure
that adequate clearance is maintained for rais-
ing the glass roof, and that objects do not
project into the opening path of the luggage
compartment lid/tailgate.
Fasten 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. Ta ke corners gently.
