0 Wipers retracted
1 Clean the windshieldCleaning the windshieldThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield. If you do so,
your vision could be obscured. For this
reason, use an antifreeze agent, refer to
page 109.
Do not use the washers when the reser-
voir is empty. This could cause damage
to the washer pump.<
Cleaning the headlamps
*
When the vehicle's lighting system is
switched on, the headlamps will also be
cleaned every fifth time the automatic
windshield washer is activated.Windshield washer jetsThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.

OverviewControlsMaintenanceRepairsDataIndex
The conceptPDC provides extra safety and conve-
nience during parking maneuvers by
providing an acoustic signal to indicate
the distance to an object. To do this,
four ultrasonic sensors in the rear
bumper measure the distance to the
nearest object.The monitoring range for
the two rear sensors extends outward
roughly 2 ft (60 cm). The range for the
two center sensors is approx. 4.9 ft
(1.50 m) wide.
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in
position 2. PDC is deactivated when
you shift back out of reverse.
Acoustic signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the inter-
vals between the tones become
shorter. A continuous tone indicates the
presence of an object less than 1 ft
(30 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 BMW center
resolve the problem.The PDC does not remove the
driver's personal responsibility
for evaluating the distance between the
vehicle and any obstacles. 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 ultra-
sonic measurement, as occurs with tow
bars and trailer couplings, and in the
vicinity of thin or wedge-shaped
objects.
Certain sources of sound, such as a
loud radio, could drown the PDC signal
tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they 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).<

Parking lamps
With the switch in this position,
the front, rear and side vehicle
lighting comes on. You can use
the parking lamps for parking. Refer to
page 81 for one-sided lighting as an
additional possibility for parking.
Low beams
When you switch the ignition off
with the low-beam headlamps
on, only the parking lamps will
remain on.
"Follow me home":
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, 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
*
The headlamps are automatically
switched on for daytime driving at
ignition key position 2.
Automatic headlamp control
*
When the switch is in this posi-
tion the system automatically
responds to changes in ambient
light ( in tunnels, at dusk, etc.) as well as
rain and snow by switching the low
beams on or off.<
The headlamps and other external
lamps remain on when you switch
on the fog lamps manually while the
headlamps are on following automatic
activation.<
Automatic headlamp control
cannot serve as a substitute for
your personal judgement in determining
when the lamps should be switched on.
The sensors are not able to detect fog,
for example . When these kinds of low-
visibility situations arise you should
switch on the lamps manually to ensure
continued safety.<

You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<
