Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Fuel gauge
Fuel tank capacity: approx. 18.5 gallons/
70 liters. You will find information on refueling
on page186.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message appears for a short time on the Con-
trol Display; the remaining range is shown in the
onboard computer. Below a range of approx.
30 miles/50 km, the message remains on the
Control Display.
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.<
Computer
Displays in instrument cluster
To display the information, press the BC button
in the turn signal lever from radio readiness.
The following information is displayed in the
specified order:
>Cruising range

Cruising range
Displays the estimated cruising range available
with the remaining fuel. The range is projected
based on the driving style over the last 20 miles/
30 km.
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.<
Average speed
Periods with the vehicle parked and the engine
switched off are not included in the calculations
of average speed.
To reset average speed: press BC button on
turn signal lever for approx. 2 seconds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
You can use the Control Display to view your
fuel consumption rate over two different dis-
tances, refer to Displays on Control Display or
Trip computer*.

Always switch off the engine before refu-
eling, otherwise no fuel can be filled into
the tank and a message is displayed.<

tainers in the vehicle. These could become
leaky and cause an explosion or a fire in an acci-
dent.<

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. 18.5 gallons/70 liters, including the
reserve capacity of approx. 2.1 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 filler cap
Closing
Fit the cap and turn it clockwise until you clearly
hear a click.
Do not jam the strap attached to the fuel
filler cap between the fuel filler cap and
the vehicle. A message is displayed if the cap is
loose or missing.<
Fuel specifications
Do not use leaded gasoline, otherwise
permanent damage to the catalytic con-
verter will result.<
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.
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.<

Maintenance

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 to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values worsen. Have the
vehicle checked as soon as possible.
Display of the previously described
malfunction in 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 led to 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 close when
fuel vapor escapes. Then a display light up. If
the cap is then tightened, the display will 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
signed a contract of participation for BMW
Assist, certain vehicle data can be transmitted
or recorded to enable corresponding services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
