Mobility -> Refueling for your BMW 6 Series 2003-2010

Refueling  
Always switch off the engine before  
Observe following when refueling  
refueling. If you do not, fuel cannot be  
filled into the tank and a message on the  
Control Display will appear.<  
When handling fuels always observe  
any safety guidelines posted at the  
filling station.<  
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.<  
Fuel filler door  
Put 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. 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.  
To open and close: briefly press the rear  
edge of the fuel filler door.  
Fuel tank capacity  
Manual release  
Approx. 18.5 US 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, as otherwise engine functions are  
not ensured and damage can occur.<  
Closing fuel filler cap  
Fit the cap and turn it clockwise until you  
clearly hear a click.  
In the event of an electrical malfunction in  
the system, 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.  
Close the fuel filler cap carefully after  
refueling, continuing until a click is  
heard. While closing, be sure not to  
squeeze the strap which is fastened to the  
cap. A loose or missing cap will activate the  
message Check Gas Cap* on the Control  
Display.<

or is missing. Check whether the  
fuel filler cap is properly closed.  
Fuel specifications  
The engine uses lead-free gasoline only.  
Required fuel  
Premium Unleaded Gasoline,  
Minimum Octane Rating: 91.  
Minimum Octane Rating corresponds to  
the Anti Knock Index AKI and is deter-  
mined according to the so-called (R+M)/  
2 method.  
Do not use leaded gasoline, as other-  
wise the lambda probe and catalytic  
converter will be permanently damaged.<  
Use high-quality brands  
Field experience has indicated significant  
differences in fuel quality: volatility, compo-  
sition, additives, etc., among gasolines  
offered for sale in the United States and  
Canada. Fuels containing up to and includ-  
ing 10% ethanol or other oxygenates with  
up to 2.8% oxygen by weight, that is,  
15% MTBE or 3% methanol plus an equiv-  
alent 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 stall-  
ing problems, especially under certain  
environmental conditions 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 recommenda-  
tions may also result in unscheduled main-  
tenance.<
