Refueling
Fuel filler door
Always switch off the engine before
refueling. If you do not, fuel cannot be
filled into the tank and a message will
appear in the Check Control.<
To open and close: briefly press the rear
edge of the fuel filler door.
Manual release
In the event of an electrical defect in the
system, you can release the fuel filler door
manually:
1.Lift the handle to remove the cover
panel on the right side of the luggage
compartment
2.Take the button with the fuel pump
symbol from the bracket and pull it to
unlock the fuel filler door.
Always observe all applicable precau-
tions and regulations when handling
fuels. Never carry spare fuel containers in
your vehicle. Whether empty or full, these
containers can leak, cause an explosion,
and lead to fire in the event of a collision.<
Simple and environmentally friendly
When handling fuels always observe
any safety guidelines posted at the
filling station.<
Put the filler cap in the bracket attached to
the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler
nozzle during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the
fuel-vapor recovery system.
The fuel tank is full when the filler nozzle
clicks off the first time.
Closing fuel filler cap
Close the filler cap carefully after refu-
eling, continuing until you hear the
detent engage. While closing, be sure not
to squeeze the strap which is fastened to
the cap. A loose or missing cap will activate
a message
* in the Check Control.<
Fuel tank capacity
Approx. 23.2 US gallons/88 liters, including
the reserve capacity of approx. 2.6 gallons/
10 liters.
Never attempt to continue driving
until the tank is completely empty, as
engine functions could be affected, and the
vehicle could sustain damage as a result.<

Engine oil
Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again 5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.
The oil quantity between the two marks
of the dipstick is approx. 1.65 US quarts/

Under the hood
196 1.5 liter. Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.
Adding engine oil
Wait until the level has dropped to just
above the lower mark or a message
appears in the Check Control before add-
ing oil.
Store oil, grease etc., well out of the
reach of children; always observe all
warning labels on the containers.<
Specified engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America
at 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
BMW engines are designed to oper-
ate without additives, and their use
could even lead to damage in some
cases.<
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
Coolant
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.<
Coolant consists of water and the addition
of antifreeze and anticorrosion agent. Not
all commercially available additives are
suitable for your BMW. Ask your BMW cen-
ter for suitable additives.
Only use suitable additives, as other-
wise engine damage may result. The
additives present a health hazard; observe
the instructions on the containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anticorrosion agents.<
Checking coolant level
1.The engine must be at ambient temper-
ature
2.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
3.The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler neck

Maintenance
The BMW Maintenance
System
The BMW Maintenance System serves to
retain the operating and road 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 aim is to optimize maintenance with
regard to reducing the cost of running the
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 inesti-
mable value.
CBS Condition Based Service
Sensors and special algorithms take the
different driving conditions of your BMW
into account. As a result, Condition Based
Service determines the current and future
maintenance requirements. By letting you
define a service and maintenance regimen
that reflects your own individual require-
ments, the system forms the basis for trou-
ble-free driving.
The service requirement display, refer to
page82, shows you the times or distances
remaining until the deadlines for selected
service and maintenance procedures, as
well as legally-mandated inspections:
>Engine oil
>Brakes, separate for front and rear
>Microfilter/activated-charcoal filter >Brake fluid
>Spark plugs
>Vehicle check
>Coolant
>Legally prescribed inspections depend-
ing on national regulations.
Your vehicle stores this information contin-
uously in the ignition key while the vehicle
is being driven. After accessing the data
stored in the vehicle key, your BMW service
advisor is able to suggest precisely the
right array of service procedures for your
own individual vehicle. You should there-
fore hand over to the BMW service advisor
the key you last used to drive when you
take your vehicle for service.
Storage periods with the battery dis-
connected are not taken into account
by the CBS maintenance system. Have the
time-dependent service and maintenance
operations, such as brake fluid and cool-
ant, and if necessary engine oil and the
micro/activated charcoal filter, updated by
a BMW center.<

Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate. Your BMW center will be
happy to advise you on all questions con-
cerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page210.
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage com-
partment to OFF. This reduces the current
flow from the battery for the period during
which the vehicle remains parked. A mes-
sage appears in the Check Control. Please
take note of the supplementary information
provided on the Control Display.
Disposal
Have old batteries disposed of follow-
ing replacement at your BMW center
or bring them to a collection point. Maintain
the battery in an upright position for trans-
port and storage. Always secure the battery
to prevent it from tipping over during trans-
port.<
Power failure
Following a temporary power failure, e.g. in
the case of a flat battery, some equipment
is subject to restricted use and must be
reinitialized. Individual settings are also lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again,
refer to page55
>Time and date
Must be updated again, refer to
page90
>Radio
Stations must be stored again, refer to
page 154
>Navigation system
The operability must be waited for, refer
to page130.
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Spare fuses are located on the fuse strip in
the glove compartment; plastic tweezers
can be found at the fuse holder in the lug-
gage compartment.
In glove compartment
Press the tab on the cover to the front, then
