Warning lamps
The indicator
2 flashes in red; a
signal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active Cruise
Control cannot automatically restore the dis-
tance to the vehicle ahead.
This indicator does not release you from your
responsibility to adapt your desired speed and
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow.
The prerequisites for operating
Active Cruise Control are not met,
e.g. as a result of ABS or DSC
interventions. Active Cruise Con-
trol is deactivated. Yo u can reactivate the sys-
tem, if desired, by brie fly pressing or pulling the
lever when road and traffi c conditions permit. It
is not possible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a re sult of heavy rain, dirt,
snow or ice. If necessary, clean the radar sensor
located in the front bump er, see arrow. Be sure
t o u se p a r t i c ul a r c a r e w h e n r e m o v i n g a ny l a y e r s
of snow or ice from the sensor.
The system cannot be activated if the sensor is
incorrectly aligned.

ControlsTechnology for driving comfort and safety
Malfunction
The warning lamp lights up. PDC is
malfunctioning. 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 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.
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 sp ot 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 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 af ter 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 page 134.
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 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 lim its 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 th e responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taki ng risks, as this could
result in an accident. <

BMW Maintenance System
The BMW maintenance system advises you of
necessary maintenance measures and helps
you maintain the traffic and operating safety of
the vehicle.
Condition Based Service CBS
Sensors and special algo rithms 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 requirem ents, the system builds
the basis for trouble-free driving.
In the instrument cluster, you can have the
remaining times or distances for selected main-
tenance tasks and any le gally prescribed dates
displayed, refer to page 84: >
Engine oil
> Brake pads: separately for front and rear
> Brake fluid
> Vehicle check
> Legally mandated in spections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your dealership Service
Advisor can read out this data from the remote
control unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore give your
dealership Service Advisor the remote control
unit that you last used.
Make sure that the date in the instrument
cluster is always se t correctly, refer to
page 86; otherwise, the effectiveness of Condi-
tion Based Service CBS is not assured. <

Care products
Regular cleaning and care contributes signifi-
cantly to the value re tention of your BMW.
BMW recommends cleaning and caring for your
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 235.
> If necessary: fold in the exterior mirrors,
refer to page 50.
> 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.

Steam jets/high-pressure washers
When using steam jets or high-pressure
washers, make sure to maintain sufficient
distance from the vehicle and do not exceed a
temperature of 140 7/60 6.
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 the sensors, e.g. of the Park
Distance Control, for an extended period and maintain a distance of at least 1 ft/30 cm from
them.
<
Manual car wash
When washing the vehicle by hand, use large
quantities of water an d 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. <
Convertible: retractable hardtop
Proceed as you would in a normal car wash.
When you open a wet hardtop, water
drops may run into the cargo area. If nec-
essary, remove items from the cargo area
beforehand to avoid water stains or soiling. <
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
Online Edition for Part no. 01 40 2 609 312 - \251 08/11 BMW AG

MobilityCare
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 sc ratches 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 produc ts for paintwork pres-
ervation that contain carnauba or synthetic
waxes.
Rubber seals
Treat only with water or rubber care products.
Do not use silicon-con taining 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, or abrasive cleaning agents and
do not use steam jets hotter than of 140 7/
60 6; otherwise, damage 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 BM W is a high quality
natural product. Slight irregularities in the
leather are a typical char acteristic of natural
leather.<
Dust and road grit in the pores and folds of the
leather have an abrasive effect, leading to
increased wear and caus ing the leather surface
to become brittle prematurely. Therefore, fre-
quently clean the leather of dust using a cloth or
vacuum cleaner.
Clean light-colored leathe r more frequently as
dust and dirt are more noticeable.
