81 Technology for safety and driving convenience
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. To do this,
four ultrasonic sensors in the rear
bumper measure the distance to the
nearest object. The range for the sen-
sors 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/1.50 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 your BMW center
resolve the problem.
PDC does not replace the driver's
personal responsibility for evaluat-
ing the distance between the vehicle
and any objects. Even when sensors
are involved, there is a blind spot in
which objects cannot be detected. This
applies especially in those cases where
the system approaches the physical
limits of ultrasonic measurement, as
occurs with tow bars and trailer cou-
plings, 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.<

87 Lamps
Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use this to signal the position of
the vehicle when it is parked. For light-
ing on one side for parking as an addi-
tional feature refer to page 88.
Low beams
When you switch the ignition off
with the low-beam headlamps
on, only the parking lamps will
remain on.
Follow me home lampsWhen you activate the headlamp
flasher after parking the vehicle and
switching off the lights, the low beams
will come on for a brief period.
You can also have this function
deactivated.<
LIGHTS ON warningWhenever you open the driver's door
after having turned the ignition key to
position 0, you will hear an acoustic
signal for a few seconds to remind you
that the lamps have not been switched
off.Daytime driving lamps*If you desire, the light switch can be left
in the low-beam position: when the
ignition is switched off, the external
lighting is also switched off.
When required, switch on the parking
lamps as usual as described under
Parking lamps.
You can have the activation set-
tings for the daytime driving lamps
programmed on your vehicle. When the switch is in this posi-
tion the system automatically
responds to changes in ambient
light, for example in tunnels, at dusk
and when it is raining or snowing, by
switching the low beams on or off.
The low-beam headlamps remain
on, regardless of the ambient
light, when you switch on the fog
lamps.<
Automatic headlamp control can-
not serve as a substitute for your
personal judgement in determining
when the lamps should be switched on.
For example, the sensors are not able
to detect fog. In such situations switch
on the lamp manually, as otherwise a
safety hazard will result.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<
