Technology for driving comfort and safety
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
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. 2 ft/60 cm from
the corner sensors, or approx. 5 ft/1.50 m from
the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the 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. 1 sec-
ond when you engage reverse gear 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.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases,
the intervals between 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.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate 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.
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 tone 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 limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
t h i n o r w e d g e - s h a p e d o b j e c t s , e t c . L o w o b j e c t s
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.
Antilock Brake System ABS
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 page124.
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 pressure 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 away 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 braking actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.<

Navigation system

Navigation system
General information
With the help of satellites and vehicle sensors,
the navigation system is able to ascertain the
precise position of the vehicle and reliably guide
you to any destination you enter.
Enter data only when the vehicle is sta-
tionary, and always give priority to the
applicable traffic regulations in the event of any
contradiction between traffic and road condi-
tions and the instructions issued by the naviga-
tion system. Failure to take to this precaution
can place you in violation of the law and put
vehicle occupants and other road users in dan-
ger.<
Navigation data
General information
Navigation data are stored in the vehicle and
can be updated.
Navigation data and authorization codes are
available from your BMW center.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page76:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>Vehicle check
>Legally mandated inspections depending
on local regulations
>Diesel particulate filter
*
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page80; otherwise, the
effectiveness of Condition Based Service CBS
is not assured.<

Care
234
Steam jets/high-pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 1407/606.
Insufficient clearance or excessive pressure or
temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer.<
When using high-pressure washers, do
not spray against the sensors and cam-
eras, e.g. of the Park Distance Control or Rear
View Camera, for an extended period and main-
tain a distance of at least 1 ft/30 cm.<
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintentional activation of the
wipers.<
Observe local regulations pertaining to
washing vehicles by hand.<
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with copious
quantities of water.
Thaw ice with a windshield deicer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz.<
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove aggressive materials such
as spilled fuel, oil, grease, brake fluid, tree sap or
bird droppings to prevent damage to the paint-
work.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, where necessary to prevent
rusting.<
BMW recommends having paintwork damage
repaired by a professional paint repair work-
shop according to BMW specifications using
original BMW paint materials.
Preservation
A preservation treatment is necessary when
water no longer beads off the clean paintwork
surface. Only use products for paintwork pres-
ervation that contain carnauba or synthetic
waxes.
Rubber seals
Treat only with water or rubber care products.
Do not use silicon-containing care prod-
ucts on rubber seals; otherwise, noise
and damage could occur.<
Chrome parts
Carefully clean vehicle parts such as the radia-
tor grill, door handles or window frames with
copious quantities of water and a shampoo
additive, especially when roads are treated with
deicing salt. For additional treatment, use
a chrome polish.

Light-alloy wheels
For technical reasons, dust is generated during
braking that is deposited on the light-alloy
wheels. Remove the dust regularly using acid-
free rim cleaner.
Do not use aggressive, acidic, strongly
alkaline and abrasive cleaning agents or
steam jets over 1407/606; otherwise, dam-
age may occur.<
Outside sensors/cameras
Keep the sensors and cameras on the
outside of the vehicle, e.g. those for Park
Distance Control, clean and free of ice to ensure
that they remain fully functional.<
Interior care
Upholstery fabrics/cloth trims/
Alcantara fabrics
Vacuum regularly with a vacuum cleaner to
remove superficial dirt.
To remove severe spots such as stains from
beverages, use a soft sponge or lint-free
microfiber cloth and suitable interior cleaners.
Follow the instructions on the packaging.
Clean the upholstery down to the seams
using a sweeping motion. Avoid strong
rubbing.<
Opened Velcro fasteners on pants or
other articles of clothing can damage the
seat covers. Ensure that Velcro fasteners are
closed.<
Leather/leather trim
The leather used by BMW is a high quality
natural product. Slight irregularities in the
leather are a typical characteristic of natural
leather.<
Dust and road grit in the pores and folds of the
leather have an abrasive effect, leading to
increased wear and causing the leather surface
to become brittle prematurely. Therefore, fre-
quently clean the leather of dust using a cloth or
vacuum cleaner.Clean light-colored leather more frequently as
dust and dirt are more noticeable.
Treat the leather at least once every two
months using a leather lotion as dirt and grease
will gradually attack the leather's protective
layer.
Carpet/floor mats*
The floor mats can be removed for cleaning.
When heavily soiled, clean carpets with a
microfiber cloth and water or textile cleaner.
Rub back and forth in the direction of travel; oth-
erwise, the carpet may become matted.
Interior plastic parts
>Imitation leather surfaces
>Lamp glasses
>Display pane of instrument cluster
>Matte parts
Clean with water and solvent-free plastic
cleaner if necessary.
Fine wood parts
Clean fine wood trim and fine wood parts with a
damp cloth. Wipe dry with a soft cloth.
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Do not clean chemically, as this may
destroy the webbing.<
Interior sensors/cameras
To clean interior sensors and cameras, e.g. of
the high-beam assistant, use a lint-free cloth
moistened with glass cleaner.
