Engine oil temperature*
During normal operation, the engine oil temper-
ature is between approx. 1607/706 and
approx. 3407/1706.
If the engine oil temperature is too high, a mes-
sage is shown on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal/
70 liters, including the reserve capacity of
approx. 2.6 US gal/10 liters. You can find infor-
mation on refueling on page208.
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 briefly appears on the Control Display;
the cruising range is shown in the 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

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 the average speed: press the BC but-
ton in the turn signal lever for approx. 2 sec-
onds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
To reset the average fuel consumption: press
the BC button in the turn signal lever for approx.
2 seconds.

Refueling
208
Refueling
Switch off the engine before refueling,
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.
Unlocking manually
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.
Observe the following when refueling
When handling fuels, follow the safety
precautions posted at the filling station. Otherwise, there is a danger of personal injury
and property damage.<
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, otherwise this
>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.
Fuel tank capacity
Approx. 18.5 US gal/70 liters, including the
reserve capacity of approx. 2.6 US gal/10 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
Insert the cap and turn it clockwise until there is
a clearly audible click.
Do not crush the band attached to the
cap; otherwise, the cap may not properly
seal and fuel vapors can escape.<
A message
* is displayed if the cap is loose or
missing.

Maintenance
222
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
instrument panel.
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 BMW Assist, then certain vehicle
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.
