Park Distance Control (PDC)*The conceptPDC assists you when you back into a
parking space. Acoustic signals alert
you to the momentary distance to an
object behind your vehicle. The system
features four ultrasonic sensors
mounted in your rear bumper. The mon-
itoring range for the two corner sensors
extends outward roughly 2 ft/60 cm,
while two centrally located sensors
detect objects at distances of up to
approx. 5 ft/1.50 m.
PDC is a parking aid that can
identify objects if they are
approached slowly, as is generally the
case when parking. Avoid driving
towards objects rapidly; due to underly-
ing physical principles, the system may
otherwise alert you too late for you to
take evasive steps.<
The system starts to operate automati-
cally approx. one second after you shift
into Reverse or move the selector lever
into the R position with the ignition key
in position 2.
Let this short period elapse before
driving backwards.<
PDC is deactivated when you shift back
out of Reverse.
You can have a signal set to con-
firm that the PDC has been acti-
vated. The signal then sounds when
you shift into Reverse or move the
selector lever into the R position. indicated by a tone sounding at various
intervals. As the distance between vehi-
cle and object decreases, the intervals
between the tones become shorter. A
continuous tone indicates the pres-
ence of an object less than 1 ft/30 cm
away.
The warning signal is canceled after
approx. three seconds if the distance to
the object remains constant during this
time – if you are moving parallel to
a wall, for instance.
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please have the problem fixed by
your BMW center.
PDC does not replace the driver's
personal responsibility for evaluat-
ing the distance between the vehicle
and any objects. Always remember that
the sensors can neither detect nor pro-
vide warnings of obstacles located
within their blind angles. This applies
especially in those cases where the
system approaches the physical limits
of ultrasonic measurement, as occurs
with tow bars and trailer couplings, and
in the vicinity of thin or wedge-shaped
objects. Moreover, low objects that
have already been detected – such as a
curb edge – can disappear out of the
detection range of the sensors before a
continuous tone sounds.
Loud sources of sound from outside or
inside the vehicle could drown out the
PDC signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they will continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in/10 cm.<

4. The resulting figure equals the avail-
able amount of cargo and luggage
load capacity.
For example, if the XXX amount
equals 1,400 lbs. and there will be
five 150 lbs. passengers in your vehi-
cle, the amount of available cargo
and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calculated
in Step 4
6. If your vehicle will be towing a trailer,
load from your trailer will be trans-
fered 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.
Stowing cargo>Load heavy cargo as far forward as
possible – directly behind the lug-
gage compartment partition – and as
low as possible
>Cover sharp edges and corners.
With the convertible top closed,
you can increase the space in the
luggage compartment – refer to
page 37 – by folding back the convert-
ible top compartment panel.
We recommend that you always fold
the convertible top compartment panel
down as soon as you have removed
your cargo from the luggage compart-
ment. This way, you can be sure that
you can always operate your convert-
ible top at any time.
At the same time, when the top is
raised you should fold the convertible
top compartment panel back up before
stowing large objects in the luggage
compartment; this precaution will help
reduce the likelihood of damage to
either the convertible top compartment
or your luggage.<
