1Clean windshield and headlamps*
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 132.
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 nozzles are
heated automatically* when the ignition
key is in position 2.
Cruise control*Starting 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 but-
ton 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.

86Technology 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. 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
behind the bumpers, while two centrally
located sensors detect objects at dis-
tances 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 remove 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.<

94Lamps
Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps to signal
the position of the vehicle when it is
parked. For lighting on one side for
parking as an additional feature, refer to
page 95.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps remain on.
Follow me home lampsWhen you activate the headlamp
flasher after parking the vehicle with the
lamps turned off, the low-beam head-
lamps will come on for a short time.
You can also have this function
deactivated. having turned the ignition key to posi-
tion 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 second position: when the igni-
tion is switched off, the external lighting
is also switched off.
You can have the activation set-
tings for the daytime driving lamps
programmed on your vehicle.<
Automatic headlamp control*
When the switch is set to this
position, the system automati-
cally activates and cancels the
low beams in response to changes in
ambient light – in tunnels, at dusk, etc. –
and in the event of rain and snow.
The vehicle's external lights
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 the
driver's judgement in determining when
the vehicle lights should be switched
on. For example, the sensors are not
able to detect fog. To avoid safety risks,
you should respond to these kinds of
low-visibility situations by switching the
headlamps on manually.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<
