Refueling
106
Refueling
Always switch off the engine before refu-
eling, otherwise, fuel cannot be added to
the tank and a message will be displayed.<
Take all precautionary measures and
observe all applicable regulations when
handling fuel. Do not carry any spare fuel con-
tainers in your vehicle. They can develop a leak
and cause an explosion or cause a fire in the
event of an accident.<
Gas cap
Opening
1.Open fuel filler door. To do so, lightly press
the rear edge.
2.Turn the gas cap counterclockwise.
3.Place the gas cap in the bracket attached to
the fuel filler door.
Closing
Fit the cap and turn it clockwise until you clearly
hear a click.
Do not jam the strap attached to the gas
cap between the gas cap and the vehicle.
A message will be displayed if the gas cap is
loose or missing.<
Manually releasing the fuel filler door
In the event of an electrical malfunction, you can
release the fuel filler door manually:1.Remove the cover from the right-hand side
panel of the luggage compartment.
2.Pull the knob with the fuel pump symbol.
The fuel filler door is released.
Observe the following when refueling
When handling fuels always observe any
safety guidelines posted at the service
station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler nozzle
during refueling leads to
>premature pump shutoff
>a reduced efficiency of the fuel-vapor
recovery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 16.1 US gallons/61 liters, including the
reserve capacity of 2.1 US gallons/8 liters.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Fuel specifications
Do not fill the tank with leaded fuel, as this
would cause permanent damage to the
catalytic converter.<

Required fuel
Premium Unleaded Gasoline
The minimum octane rating is 91.
If you use gasoline with this minimum octane
rating, the engine may produce knocking
sounds when starting at high outside tempera-
tures. This has no affect on the engine life.
Minimum octane rating corresponds to the Anti
Knock Index AKI and is determined according
to the so-called (R+M)/2 method.
Do not fill the tank with leaded fuel, as this
would cause permanent damage to the
catalytic converter.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing 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
drivability, starting and stalling problems
especially under certain environmental condi-
tions 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.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

Socket for On-Board
Diagnosis OBD
Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located on the driver's side to the
left, on the bottom of the instrument panel
underneath a cover.
Exhaust emission values
The warning lamps come on. The
exhaust emission values have wors-
ened. Have the car checked as soon
as possible.
Canadian models display these warn-
ing lamps.
The lamps flash under certain condi-
tions. This indicates excessive misfiring in the
engine. If this happens, you should reduce your
speed and visit your nearest BMW Center as
soon as possible. Severe engine misfiring can
quickly lead to serious damage of emissions-
related components, especially the catalytic
converter.
If the gas cap is not properly tightened, the OBD
system will assume that fuel vapor is escaping.
An indicator will then light up. If the gas cap is
then tightened, the indicator will go out within a
few days.
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle data or information. In addition, if you have
signed a subscription contract for BMW Assist,
certain vehicle data may be transmitted or
recorded in order to facilitate the corresponding
services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
