FLAT TIRE MONITOR PARK DISTANCE CONTROL (PDC)*
Do not initialize the system when
snow chains are fitted. When driving
with snow chains, false alarms can occur or
pressure losses might not be detected.<
In the following situations false
alarms can also occur under certain
circumstances or the detection of inflation
pressure loss can be delayed:
> When driving on roads covered with
snow or on other slippery road surfaces
> A sporty driving style (slip at the driven
wheels, high lateral accelerations).<
The concept
The PDC assists you when you back into a
parking space. A signal warns you of the
distance to an obstacle. To do this, four
ultrasonic sensors in the rear bumper
measure the distance to the nearest object.
The range for the sensors located at both
rear corners ends approx. 2 ft (60 cm)
behind the bumpers. The range for the two
middle sensors is slightly less than 5 ft
(1.5 meters).
The system starts to operate automatically
about one second after you select reverse
with the ignition key in position 2. PDC is
deactivated when you shift back out of
reverse.
Acoustical signals
The distance to the nearest object is indi-
cated by a tone sounding at various inter-
vals. As the distance between vehicle and
object decreases, the intervals between the
tones become shorter. A continuous tone
indicates the presence of an object less
than 9 in (20 cm) away.
The warning signal is canceled after
approx. three seconds if the distance to the
obstacle 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 your MINI center resolve the problem.
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. Moreover, the
detection of obstructions can approach the
physical limits of ultrasonic measurement,
as occurs e. g. in the case of thin and
wedge-shaped objects.
Certain sources of sound, such as a loud
radio, 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 effectively.
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).<
