Deactivate the rain sensor when passing
through an automatic car wash. Failure to
do so could result in damage caused by undes-
ired wiper operation.<
Cleaning windshield, headlamps and
BMW Night Vision camera*
Pull the lever, arrow4.
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
With the vehicle lighting switched on, the head-
lamps and the BMW Night Vision camera are
also cleaned simultaneously at suitable inter-
vals.
Do not use the washing mechanisms if
there is any danger that the fluid will
freeze on the windshield. If you do so, your
vision could be obscured. To avoid freezing,
use a washer fluid antifreeze, refer to Washer
fluid. Do not use washing mechanisms when
the washer fluid reservoir is empty, otherwise
you will damage the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated
when the engine is running or the ignition is
switched on.
Washer fluid
Washer fluid antifreeze is flammable. For
this reason, keep it away from ignition
sources and store only in the closed original
container out of reach of children. Otherwise,
there is the danger of bodily injury. Always
observe the instructions for use provided on the
containers.<
Filler neck for washer fluid
All washer nozzles are supplied from one reser-
voir.
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order to maintain the mixture ratio, mix
the washer fluid before filling.<
Capacity
Capacity approx. 5.3 US quarts/5 liters.
Cruise control*
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn. To maintain the specified speed, the sys-
tem brakes if the engine braking effect is not
sufficient on a downhill grade. Speed can drop
on uphill grades if the engine output is insuffi-
cient.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads, in heavy traffic or in poor road conditions
such as snow, rain, ice, loose road surface, and
poor visibility. Otherwise you could loose con-
trol of the vehicle and cause an accident.<

vated
>when DSC comes on
>when you apply the handbrake
>when you release the safety belt and open
the driver's door with the vehicle stopped
>when the system does not recognize any
objects for an extended period of time, e. g.
on infrequently traveled roads without a
shoulder or guard rails, or if the radar sensor
is covered with dirt, refer to page72
If the system is interrupted, then it is nec-
essary for the driver to actively intervene
by braking and steering. Otherwise, there is a
risk of an accident.<

The indicator2 continuously
flashes yellow.
The prerequisites for operating the
system are no longer met, e.g. as a
result of ABS or DSC interven-
tions. The system brakes until you actively take
over.
The indicator2 flashes red; a sig-
nal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. The system can-
not automatically restore the distance to the
vehicle driving ahead.
However, this display cannot relieve the driver
of the responsibility for adjusting the desired
speed and driving style to the traffic conditions.
Radar sensors
1Long-range sensor
2Location of the short-range sensors behind
the bumper
Heavy rain and also dirt, snow or ice can limit
the detection of vehicles ahead. If needed,
clean the radar sensor under the front bumper
as well as the bumper area covering the short
range sensors. When doing so, be particularly
careful in removing layers of snow and ice.
Do not apply adhesive labels etc. in the area of
the short-range sensors.

If the sensor is not aligned properly, e. g. due to
damage, the active cruise control cannot be
activated.
System limitations
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on free-
way-type roadways where traffic is moving rel-
atively smoothly. Do not use this system in city
driving; in complex driving situations; on curvy,
winding roads, slippery roads or roads with
sharp curves such as highway off-ramps; during
inclement weather such as snow, strong rain or
fog; or when entering interchanges, service/
parking areas or toll booths. It is also important
to regulate your vehicle’s speed and distance
setting within applicable legal limits. Always be
ready to take action or apply the brakes if nec-
essary, especially when the system is actively
following a vehicle in front of you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. For example, the system may not detect
vehicles driving ahead if they suddenly brake
heavily in stop-and-go traffic during accelera-
tion. The system will not apply the brakes or
slow your vehicle when a very slow-moving
vehicle, stopped vehicle or stationary object is
in the lane ahead of you, for example when
approaching a traffic light or parked vehicle or
when a vehicle is stalled in your lane. Also, the
system does not react to oncoming traffic, pedestrians or other types of potential traffic
s u c h a s a r i d e r o n a h o r s e b a c k . I t i s a l s o p o s s i b l e
that the system may not detect smaller moving
objects such as motorcycles or bicycles. Be
especially alert when encountering any of these
situations as the system will neither automati-
cally brake, nor provide a warning to you. Also,
be aware that every decrease in the distance
setting allows your vehicle to come closer to a
vehicle in front of you and requires a heightened
amount of alertness.<
The system cannot allow the vehicle to drive off
automatically in situations that make driving off
considerably more difficult, e.g. on steep uphill
grades, with a heavy trailer or before raised
areas in the road.
Near radio astronomy stations, the system
radar is deactivated at speeds under 20 mph/
30 km/h due to legal regulations.
Be certain to interrupt the system when
you pull into an exit lane for a highway
offramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system’s
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
In addition, the system is interrupted
whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any inter-

Technology for comfort, convenience and safety
88 a signal tone sounds. The setting is stored for
the remote control currently in use.
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Turn the controller until "Settings" is
selected and press the controller.
4.Turn the controller until "Vehicle / Tires" is
selected and press the controller.
5.Change to upper field if necessary. Turn the
controller until "PDC" is selected and press
the controller.
6.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display appears on the Control Display as
soon as PDC is activated.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstacles always remains with
the driver. Even when sensors are provided,
there is a blind spot in which objects can no
longer be detected. The system is also subject
to the physical limits that apply to all forms of ultrasonic measurement, such as those
encountered with tow bars and trailer cou-
plings, or thin and wedge-shaped objects etc.
Low objects already displayed, e. g. curbs, can
also disappear from the detection area of the
sensors again before or after a continuous tone
already sounds. Higher, protruding objects, e.g.
ledges, cannot be detected. For this reason,
drive with care; otherwise, there is a danger of
personal injury or property damage.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme 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. For information on safe braking, refer to
page128.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
produces maximum braking force boosting and
thus helps to achieve the shortest possible
braking distance during full braking maneuvers.
This system exploits all of the benefits provided
by ABS.

Maintenance
BMW Maintenance System
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, a complete dealer service history
will prove to be an asset of inestimable value.
CBS Condition Based Service
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.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page79:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in remote control
Your vehicle stores the information required
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. You should therefore hand over the remote
control you last used to drive to the BMW Ser-
vice Advisor when you take your vehicle in for
service.
Make sure the date is set correctly, refer
to page85, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<

Care
Car-care products
Regular cleaning and care make a significant
contribution to retaining your BMW's value.
For the cleaning and care of your vehicle, BMW
recommends using only products that BMW
has approved for this purpose.
Your BMW center will be glad to advise you
about products and services for the cleaning
and care of your BMW.
Genuine BMW Care Products are materi-
als tested, laboratory tested, and tested in
actual use. They offer optimum care and pro-
tection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents; they can damage your vehi-
cle.<
Cleaning agents can contain substances
that are dangerous or pose health risks.
You should therefore heed the warnings and
hazard indications on the packaging. Open the
doors or windows on your vehicle whenever
cleaning the interior. Make sure there is suffi-
cient ventilation in enclosed spaces. Use only
products that are formulated for vehicle clean-
ing.<
Exterior care
Washing your vehicle
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Otherwise, signifi-
cant soiling and road salt can cause damage to
the vehicle.<
After washing the vehicle, apply the
brakes briefly to dry them. Failure to do so
may lead to a reduction in braking efficiency and
also to corrosion of the brake rotors.<
Car washes
Give preference to cloth car washes.Do not use high-pressure car washes
because they can cause drops of water to
penetrate in the vicinity of the windshield.<
Before driving into the car wash, make sure that
it is suitable for your BMW. Pay attention to the
following points:
>Dimensions of your vehicle, refer to
page243.
>If necessary, fold in the outside rearview
mirrors, refer to page55.
>Maximum permissible tire width.
>The convertible top must not be treated
with wax. Make sure that a program without
wax or a special convertible program is
available.
Preparations for driving into the car wash:
>Deactivate rain sensor to prevent unwanted
wiper activation.
>Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
Automatic transmission
Before driving into the car wash, make sure the
vehicle is able to roll by making sure to:
1.Insert the remote control into the ignition
lock, even with comfort access.
2.Shift into transmission position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
Steam cleaners/high-pressure
cleaning jets
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 606.
Insufficient distance or excessive pressure or
temperature can damage parts of the vehicle or

Care
228 can result in water penetration. Follow the oper-
ating instructions for the high-pressure clean-
ing jets.<
When using high-pressure cleaning jets,
do not remain in one place for a long time
and be sure to maintain a distance of at least
12 in/30 cm from sensors, e.g. Park Distance
Control sensors or radar sensors.<
Hand washing
When washing the vehicle by hand, use plenty
of water and car washing shampoo. Clean the
vehicle with gentle pressure using a sponge or a
washing brush.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unwanted wiper operation.<
Follow local guidelines for washing vehi-
cles by hand.<
Headlamps
Do not rub dry and never use abrasives or
strong solvents to clean the covers.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with plenty of
water.
Use a window de-icer to remove accumulated
ice and snow, not a scraper.
Windows
Use a glass cleaner to clean the inside and out-
side surfaces of the windows and the glass sur-
faces of the mirrors.
Do not use quartz-containing cleansers
to clean glass surfaces of the mirrors.<
Wiper blades
Clean with soapy water and replace regularly to
prevent streaking.
The presence of wax and sealant residues
and dirt on the windows leads to streaking
during wiper operation and results in premature
wear on wiper blades as well as interference
with the rain sensor.<
Convertible top care
The appearance and service life of the convert-
ible top depend on proper care and operation.
Please follow these instructions:
>Never stow the convertible top in the con-
vertible top compartment when it is wet or
frozen, since this can cause water marks,
mildew stains, and scuff marks.
>Remove water marks on the headliner with
a microfiber cloth and interior cleanser.
>When parking for long intervals in enclosed
spaces, make sure there is sufficient venti-
lation.
>Remove bird droppings immediately
because their caustic properties have a cor-
rosive effect on the convertible top and can
damage the rubber seals.
Do not use stain remover, paint thinner,
solvents, gasoline, or the like to remove
stains. These substances can damage the rub-
ber coating. Improper care and cleaning can
cause leaks to develop in the convertible top
and its seams.<
In the event of more serious soiling, use a spe-
cial convertible top cleaner.
When doing so, follow the manufacturer's
directions for use.
After three to five washings, treat the convert-
ible top with sealant.
Caring for the vehicle finish
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggressive substances.
Regionally occurring environmental factors can
affect and damage vehicle finish. It is therefore
important to tailor the frequency and extent of
your car care accordingly.
Immediately remove particularly aggressive
substances such as spilled fuel, oil, grease,
brake fluid, tree resin, or bird droppings; other-
wise, they may damage your paint.
