Refueling
Switch off the engine before refueling.
When handling fuel, always observe all
applicable precautionar y measures and regula-
tions. Never transport reserve fuel containers in
the vehicle. These co uld become leaky and
cause an explosion or a fire in an accident. <
Fuel filler door
Opening
1.Open the fuel filler door. To do this, briefly
press the lower edge.
2. Turn the fuel filler cap counterclockwise.
3. Place the fuel filler cap in the bracket
attached to the fuel filler door.
Closing
Fit the cap and turn it cl ockwise until you clearly
hear a 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.
Releasing manually
If an electrical malfunction should occur, you
can unlock the fuel filler door manually.
1. Open the right-hand side panel in the cargo
bay.
2. Pull the knob with the gas pump symbol.
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
or property damage. <
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid raising the filler
nozzle during refueling, otherwise this 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 specifications
Gasoline engine: required fuel
Do not use leaded gasoline, otherwise
damage to the catalytic converter will
result.
Do not use E85, i.e. fuel that consists of 85 %
ethanol, or Flex Fuel, otherwise permanent
damage to the engine and the fuel supply sys-
tem will result. <
Super Premium Gasoline/AKI 91
This gasoline is hi ghly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is 87.
If you use gasoline with this minimum AKI Rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no affect on the engine life.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result. <
Use high-quality brands
Field experience has in dicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among ga solines 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 warranti es with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certai n 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
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in un scheduled maintenance. <
BMW X5 with BMW Advanced Diesel:
Required fuel
Ultra-low sulfur diesel
The engine of your BMW is designed for diesel
with a low sulfur content:
Ultra-low sulfur diesel ASTM D 975-07a.
Refuel only with ultra-low sulfur diesel.
The percentage of biodiesel in the fuel
must not exceed 5 Ξ, referred to as B5. Do not
refuel with gasoline. If the vehicle has been
refueled with incorrect fuel such as gasoline, do
not start the engine; otherwise, there is a dan-
ger of engine damage. <
After incorrect refueling, contact a BMW Sports
Activity Vehicle Center.
The fuel filling neck is designed for refuel-
ing with diesel nozzles.
If the nozzle cannot be inserted into the fuel
filler pipe of your BMW, please check to make
sure that you are refueling with a diesel fuel
pump and whether this is equipped with a diesel
nozzle. <
Winter diesel
In order to assure the operational reliability of
the diesel engine, during cold seasons, please
refuel with winter diesel, which is sold at fuel
stations during this time of year. The standard
fuel filter heating prevents the supply of fuel
from stalling during driving.
Do not mix in any additives or gasoline;
otherwise, there is the risk of engine dam-
age. <
BMW X5 with BMW Advanced
Diesel
The concept
BMW Advanced Diesel reduces nitrogen oxides
in the diesel exhaust of your vehicle by injecting
the reducing agent diesel exhaust fluid into the
exhaust line. In the cata lytic converter, a chem-
ical reaction occurs th at minimizes nitrogen
oxides.
