Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, as your vision
could be obscured. Always use a wind-
shield washer antifreeze in cold
weather. Refer to page 122.
Do not use the washers when the reser-
voir is empty. This could cause damage
to the washer pump.<
The system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
When the vehicle's lighting system is
switched on, the headlamps will also be
cleaned at reasonable intervals.Windshield washer nozzlesThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.
Cruise controlStarting at about 20 mph / 30 km/h, you
can maintain and store any vehicle
speed that you specify.
The cruise control is operational when-
ever the engine is running and the sys-
tem has been activated.To activate the systemIn ignition key position 2:
Press the button in the steering wheel.
The indicator lamp in the instrument
cluster comes on, refer to page 20. You
can now use the cruise control.
Do not use cruise control on twist-
ing roads, when high traffic den-
sity prevents driving at a constant
speed, or when the road surface is slick
– snow, rain, ice – or loose – rocks or
gravel, sand. until the indicator lamp in the instru-
ment cluster goes out.
Cruise control is also deactivated when
the ignition key is in position 0.
Washer/wiper system/Rain sensor*

82Technology 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.<

88Lamps
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 89.
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 – in tunnels, at dusk, etc. – and in
the event of rain and snow – by switch-
ing the low beams on or off.
The vehicle's external lamps
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
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.<
