Refueling
186
Refueling
Always switch off the engine before refu-
eling, otherwise no fuel can be filled into
the tank and a message is displayed.<
When handling fuel, always observe all
applicable precautionary measures and
regulations. Never transport reserve fuel con-
tainers in the vehicle. They can leak and cause
an explosion or a fire in an accident.<
Fuel filler door
To open and close: briefly press the rear edge of
the fuel filler door.
Manual release
In the event of an electrical malfunction, you can
release the fuel filler door manually:
In the luggage compartment, pull the knob with
the gas pump symbol on the right side panel.

When handling fuels always follow any
safety guidelines posted at the gas sta-
tion.<
Place the fuel filler cap in the bracket attached
to the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid raising the filler
nozzle during refueling, as otherwise this
>results in premature pump shutoff
>can lead to reduced efficiency in the fuel-
vapor recovery system

Fuel specifications
Never used leaded gasoline; it will perma-
nently damage the catalytic converter.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no affect on the engine life.
Use high-quality brands
Field experience has demonstrated significant
differences in fuel quality: volatility, composi-
tion, additives, etc., among gasolines offered for
sale in the United States and Canada. Fuels
containing up to and including 10 % ethanol or
other oxygenates with up to 2.8 % oxygen by
weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will
not void the applicable warranties with respect
to defects in materials or workmanship.
The use of poor-quality fuels may result in
problems relating to drivability and start-
ing, and to a tendency to stall, especially under
certain environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

Engine oil
Engine oil consumption depends on driving
style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check.
The condition for the most accurate indication
of the oil level possible is measurement with the
engine at operating temperature, i.e. following
an uninterrupted drive of at least 6 miles/10 km.
You can display the oil level on the Control Dis-
play while driving or when stopped on a level
surface with the engine running.
iDrive, for explanation of principle, refer to
page16.1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.

ler. The oil level is displayed.
Possible messages
>"Engine oil level O.K."
>"No measured value available: Updating
engine oil level measurement...":
Engine oil level is being measured. This
process can take approx. 3 minutes when
stopped on a level surface and approx.
5 minutes while driving.
>"Oil level at the minimum! Refill with 1 quart
of engine oil.":
Add 1 US quart/liter of engine oil at the next
opportunity.
>"Engine oil level too high":
Have the vehicle checked immedi-
ately; otherwise, engine damage may
result if too much oil has been added.<
>"Please observe recalculated service inter-
val for engine oil":
Do not add engine oil. Continued driving is
possible. To do this, observe the recalcu-
lated remaining mileage until the next oil
change service, refer to page199. Have the
system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of oil until a corre-
sponding message is shown on the Control Dis-
play.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.<
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, thoroughly wash exposed areas
of skin with soap and water after such work.
Keep oil, grease, etc. out of reach of children
and heed warnings on containers. Failure to do
so could pose health risks.<
Oil change
Have oil changes carried out only by a BMW
center or a repair shop that works in accordance
with BMW guidelines and uses appropriately
trained personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Use only approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes. Use
only oils of the specification API SH or higher.
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<

Do not use oil additives; under some cir-
cumstances, they can harm your
engine.<
Viscosity grades
The viscosity is a measure of the thickness of
the oil and is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the SAE grades
5W-40 and 5W-30.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.The coolant level is correct when it lies
between the Min and Max mark, also refer to
the drawing next the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until it clicks.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.

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, you will find that a complete dealer
service history is 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 page77:
>Engine oil
>Brake pads, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs>Vehicle check
>Legally required tests 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. For this reason, when you take your vehicle
in for service, you should give the BMW Service
Advisor the remote control last used to drive it.
Make sure the date is always set cor-
rectly, refer to page83, as otherwise the
effectiveness of CBS Condition Based Service
is not ensured.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
dashboard.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values are deteriorating.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction on Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case, you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
escape of fuel vapor. This causes a display to
light up. If the cap is then tightened, the display
should go out within a few days.<
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with a
device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to a BMW Assist plan, then certain vehi-
cle data can be transmitted or recorded to
enable corresponding services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.
