Refueling
Fuel filler door
1.Open fuel filler door
2.Turn the gas cap in a counter-clockwise
direction
3.Place the gas cap in the bracket on the
filler door.
Releasing manually
If an electrical malfunction occurs, you can
unlock the fuel filler door manually:
1.Remove the covers of the tail lamps by
turning the lock to the right; refer also to
page 90
2.Pull the luggage compartment trim
panel slightly toward the interior.
The green button with the fuel pump
symbol is revealed
3.Undo the adhesive strip and pull off
4.Pull the button
The fuel filler door is released.
Pull on the button slowly and
carefully as it could otherwise be
torn off.<
Fuel gas cap
Close the gas cap carefully after refuel-
ing until a click is heard. While closing,
be sure not to squeeze the strap which is fas-
tened to the cap. A loose or missing cap will
activate the CHECK GAS CAP lamp
*.<
Check Gas Cap
*
This indicator lamp comes on when
the gas cap is loose or missing.
Close the gas cap tightly as described
above.
Tank capacity: approx. 14.5 gallons/
55 liters, of which approx. 2.1 gallons/
8 liters are reserve capacity.
Simple and environmentally friendly
When handling fuels, comply with all
of the applicable safety precautions
posted at the service station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the nozzle
during refueling
>results in premature shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full when the filler nozzle
shuts off the first time.
Fill the fuel tank before it is com-
pletely empty. Driving to the last drop
of fuel can prevent the engine from operat-
ing properly and result in damage.<
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
Do not use leaded fuels. The use of
leaded fuels will cause permanent
damage to the system's oxygen sensor and
the catalytic converter.<

In the engine compartment
84 The oil volume between the two marks on
the dipstick corresponds to approx.
1.1 quarts/1 liter. Do not fill beyond the
upper mark on the dipstick. Excess oil will
damage the engine.
Adding engine oil
While you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never allow
the oil level to fall below this mark.
BMW engines are designed to oper-
ate without oil additives; the use of
additives could even lead to damage in
some cases. This also applies to manual
and automatic transmissions and to the dif-
ferential.<
Continuous exposure to used oil has
caused cancer in laboratory tests. For
this reason, thoroughly wash any areas of
skin that come into contact with oil using
soap and water.
Always store oils, grease and similar mate-
rials so that they are inaccessible to chil-
dren. Comply with warning labels and the
information on the containers.<
Comply with the applicable environ-
mental laws regulating the disposal of
used oil.<
Approved engine oils
The quality of the engine oil is extremely
important for the function and life of an
engine. Based on extensive testing, BMW
has approved certain grades of engine oil.
Use approved High Performance Synthetic
Oil.
If you are unable to obtain an approved
High Performance Synthetic Oil, you may use small volumes of other synthetic oils for
topping up between oil changes. Use only
oils with the specification API SH or higher.
Ask your BMW center for details con-
cerning the specific High Perfor-
mance Synthetic Oil or synthetic oils that
have been approved.<
You can also call BMW of North America
toll-free at 1-800-831-1117 or visit this
website: www.bmwusa.com to obtain this
information.
Coolant
The yellow coolant indicator lamp
lights up:
The coolant level is too low: top up
as soon as possible.
Do not add coolant to the cooling sys-
tem when the engine is hot. If you do,
escaping coolant can cause burns.
Antifreeze and anti-corrosion agents are
hazardous to health. You should always
store them in their original containers and
in a location inaccessible to children.
Antifreeze and anti-corrosion agents are
flammable. For this reason, do not spill
them on hot engine parts. They could ignite
and cause burns. Comply with the instruc-
tions on the containers.<
Checking the coolant level
Correct coolant level when the engine is
cold, approx. 687/206:
1.Open the cap of the expansion tank by
turning it slightly counterclockwise to
