Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Park Distance Control PDC
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator warn you of the presence of an object
in front of or behind your vehicle. To measure
the distance, there are four ultrasonic sensors
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the front sensors and rear corner sensors,
or approx. 5 ft/1.50 m from the rear center sen-
sors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually th e case when parking.
Avoid approaching an object at high speed; oth-
erwise, physical circumstances may lead to the
system warning being issued too late. <
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. one
second when you shift into reverse or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above
approx. 20 mph/approx. 30 km/h, the system
switches off and the LED goes out.
Switching on manually
When parking in the forward direction, the sen-
sors must be switched on manually to enable
them to signal an approach to an object in front
of or behind the vehicle.
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. For exam-
ple, if an object is dete cted behind the vehicle,
the signal tone sounds from the rear. As the dis-
tance between vehicle an d object decreases,
the intervals betwee n the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds
> If you remain in front of an object that has
been detected by only one of the corner
sensors
> If you are driving parallel to a wall.

Technology for driving comfort and safety
Controls
Malfunction
The warning lamp lights up. A mes-
sage appears on th
e Control Display.
PDC is malfunctioning. Have the sys-
tem checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to op erate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 1 ft/30 cm.
Manual operation
The LED above the button also flashes.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal to ne sounds. The display
appears on the Control Display as soon as PDC
is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limit s that apply to all forms
of ultrasonic measurement, such as those
encountered with traile r towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously; otherwise, there is a risk of personal
injury or property damage.
Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously; otherwise, there is a
risk of personal injury or property damage. <
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page140.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressu re on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull aw ay from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through brakin g actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains th e responsibility of the
driver. Therefore, do not reduce the additional

Lamps
Controls
High-beam Assistant
The concept
This system automatica
lly switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handle s this task for you and
gives you the benefit of the best possible view.
You can intervene at any time and switch the
high beams on and off as usual.
Activating the system
1. Turn the light switch to position 3, refer to
page 110.
2. With the low beams switched on, briefly
push the turn signal/high beam lever in the
direction of the high beam.
The indicator lamp in the instrument
cluster lights up when the high beams
are activated. The system automati-
cally switches from hi gh beams to low beams
and vice versa in response to oncoming traffic,
traffic ahead of you, and adequate ambient
lighting, e.g. on city streets.
Switching the high beams on and off
manually
Whenever you wish, or when the situation
requires, you can intervene:
> If the High-beam Assistant switches on the
high beams, but you would like to drive with
the low beams, simply switch off the high
beams using the turn signal/high beam
lever. This deacti vates the High-beam
Assistant.
To reactivate the syst em, briefly push the
turn signal/high beam lever toward the high
beams again. >
If the High-beam Assistant switches on the
low beams, but you would like to drive with
the high beams, switch on the high beams
as usual. This deacti vates the system and
the high beams need to be switched off
manually, if necessary.
To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again.
> Use the headlamp flasher as usual with the
low beams switched on.
System limitations
The High-beam Assistant cannot serve
as a substitute for the driver's personal
judgment of when to use the high beams.
Therefore, manually switch off the high beams
in situations where this is required to avoid a
safety risk.<
The system is not fully fu nctional in situations
such as the following, and driver intervention
may be necessary:
> In very unfavorable weather conditions,
such as fog or heavy precipitation
> In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings
> In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways
> In poorly lit towns and cities and in the pres-
ence of highly reflective signs
> At low speeds
> When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
> If the sensor is dirty. Clean the sensor on
the front of the interior rearview mirror using
a cloth moistened with a small amount of
glass cleaner.

vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material-tested, laboratory-checked and
proven in the field, and offer optimal care and
protection for your vehicle. <
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles. <
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling an d road salt can lead
to vehicle damage. <
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and the brake discs can corrode. <
Automatic car washes
Give preference to car washes that use cloth or
soft brushes in order to avoid paint damage.
Do not use high-pressure car washes;
otherwise, water may drip into the vehicle
around the windows. <
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
> Dimensions of your vehicle, refer to
page 285.
> If necessary: fold in the exterior mirrors,
refer to page 55.
> Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is the
danger of damaging chassis parts. <
Preparations before driv ing into an automatic
car wash:
> Unscrew the rod antenna.
> Deactivate the rain sensor to prevent
undesired wiper operation.
> Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
> Leave the remote control in the ignition
lock.
