2006 BMW 325I trailer

Technology for driving comfort and safety
84 1.Open the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.If necessary, move the highlight marker to
the uppermost field. Turn the controller
until "PDC" is selected and press the con-
troller.
5.Select "PDC display on" and press the con-
troller.
6. The PDC screen is activated.
The setting is stored for the remote control cur-
rently in use.
The display is shown on the Control Display as
soon as PDC is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and couplings,
thin and wedge-shaped objects, etc. Low
objects already indicated, such as a curb, may
enter the sensors' dead areas before a continu-
ous audible signal is given. Higher, protruding
objects, such as ledges, may not be detectable.
Loud sound sources outside or inside the car
can drown out the PDC signal.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
ABS Antilock Brake System
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 page117.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps 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 brake application. If the brake is
released, DBC will be switched off.
DSC Dynamic Stability Control
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. DSC 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 vehicle maintain a safe course
within physical limits by reducing engine output
and through braking actions at the individual
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
safety margin again by taking risks.<

cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
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 backs.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
Securing cargo
>Smaller and relatively light items can be
retained with tensioning straps 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 inside rear wall of
the luggage compartment 1, and two others
are on the side walls of the luggage com-
partment 2.
Comply with the information provided 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 swerves are necessary.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page220, as excessive loads can pose a
safety hazard, and may also 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.<
Roof-mounted luggage rack*
A special rack system is available as an option
for your BMW. Comply with the precautions
included with the installation instructions.
