PDC with visual warning
You also enjoy the option of having the
system show distances to objects in the
Control Display. The Control Display will
also indicate the presence of objects in
green before they are close enough to gen-
erate a signal tone.
Select "PDC pic." from the "Settings" menu
and confirm your selection. This activates
the PDC display.
The display then appears in the Control
Display whenever the PDC is automatically
or manually activated.
The previous display automatically reap-
pears after the system is deactivated.
Confirm in the menu to return to
the previous display.<
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors
are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with tow bars
and trailer couplings, as well as thin and
wedge-shaped objects, etc. Low objects already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside the
vehicle may prevent you from hearing
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in (10 cm) away
from the sensors.<
Driving stability control/
DSC Dynamic Stability
Control
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on DSC and ABS.
The concept
DSC 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.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.
With its selective braking intervention at the
individual drive wheels, DTC fulfills the
same function as a conventional limited-
slip differential to enhance traction under

Giving and receiving assistance
204 this could lead to damage that might ulti-
mately result in an accident.<
To avoid jerking and the associated
stresses on vehicle components when
towing, always use either a tow bar or a
nylon rope.
Keep the vehicles in line, taking care
to avoid towing at an offset angle, and
make certain that the tow rope connecting
the two vehicles is tight before starting
off.<
Tow bars
The tow fittings used should be on the
same side on both vehicles.
Should it prove impossible to avoid moun-
ting the tow bar at an offset angle, please
observe the following:
>Clearance and maneuvering capability
will be strictly limited in corners
>When mounted at an angle, the tow bar
will exert lateral forces, tending to push
the vehicle sideways.
Never use a vehicle to tow another
vehicle that is heavier than itself, as
this could lead to a loss of control.<
Towing
Do not tow the vehicle by the rear
axle; because the steering detent is
not operational, the wheels could turn to an
extreme angle during towing.<
1.Turn on the ignition to allow operation
of the brake lamps, turn signal indica-
tors, horn, parking brake and winds-
hield wipers
2.Turn on the hazard warning flashers
where allowed by law
3.Release the transmission lockout man-
ually, refer to page 70
4.Towing speed:
maximum of 45 mph (70 km/h)
5.Towing distance:
maximum of 90 miles (150 km).
If the electrical system in the towed vehicle
has failed, use an alternate means to iden-
tify the vehicle as being towed such as a sign or warning triangle placed in the rear
window.
The steering and brakes are without
power assistance when the engine is
off. This means that higher levels of effort
will be required to operate the steering and
brakes.<
Tow-starting
It is not possible to start the engine by tow-
starting the vehicle.
Jump-starting, refer to page 203.
Have the source of the starting difficulties
diagnosed and repaired at your BMW
center.
Towing with a commercial tow truck
>Do not tow with sling-type equipment
>Use a wheel lift or flatbed carrier
>Please comply with applicable towing
laws.
Never allow passengers to ride in a
towed vehicle for any reason.<
