Refueling
Notes
Switch off the engine before refueling
Always switch off the engine before refu‐
eling; otherwise, fuel cannot be added to the
tank and a message will be displayed.
◀
Observe when handling fuel
▷ Take all precautionary measures and
observe all applicable regulations
when handling fuel.
▷ Do not carry any spare fuel containers in
your vehicle. They can develop a leak and
cause an explosion or cause a fire in the
event of an accident.◀
Fuel cap
Opening
1. Briefly press the rear edge of the fuel filler
flap. 2.
Turn the fuel cap counterclockwise.
3. Place the fuel cap in the bracket attached to
the fuel filler flap.
Closing
1. Fit the fuel cap and turn it clockwise until you
clearly hear a click.
2. Close the fuel filler flap. Do not pinch the retaining strap
Do not pinch the retaining strap attached
to the cap; otherwise, the cap cannot be closed
properly and fuel vapors can escape.◀
A message* is displayed if the cap is loose or
missing.
Manually unlocking fuel filler flap
In the event of a malfunction, the fuel filler flap
can be released manually:
1. Open the right-hand side panel in the cargo
area.
2. Pull the knob with the gas pump symbol. Observe the following when
refueling
When refueling, insert the filler nozzle com‐
pletely into the filler pipe. Lifting up the fuel
pump nozzle during refueling causes:
▷
Premature pump shutoff.
▷ Reduced efficiency in the fuel-vapor recov‐
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Handling fuels
Follow the safety instructions provided at
gas
stations; otherwise, there is a danger of per‐
sonal injury and property damage.◀ Seite 246

Fuel
Fuel specifications
Gasoline engine: required fuel
Do
not use fuels that are labeled at the fuel pump
as containing metals.
Only refuel with lead-free gasoline without
metal additives
Do not refuel with leaded gasoline or gasoline
with metal additives, e. g., manganese or iron;
otherwise, the catalytic converter and other
components will be permanently damaged.◀
Do not refuel with ethanol E85
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply sys‐
tem.◀
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is:
▷ BMW X5: 87
▷ BMW X6: 89
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.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum specified fuel grade; otherwise, engine
damage may occur.◀
Use high-quality brands
Field
experience has indicated significant differ‐
ences in fuel quality: volatility, composition, ad‐
ditives, etc., among gasolines offered for sale in
the United States and Canada. Fuels containing
up to and including 10% ethanol or other oxy‐
genates with up to 2.8% oxygen by weight, that
is, 15% MTBE or 3% methanol plus an equiva‐ lent amount of co-solvent, will not void the ap‐
plicable warranties with respect to defects in
materials or workmanship.
Minimum fuel grade
The
use of poor-quality fuels may result in
driveability, starting and stalling problems es‐
pecially under certain environmental conditions
such as high ambient temperature and high al‐
titude.
Should you encounter driveability 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 result in unscheduled 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.
Only refuel with ultra-low sulfur diesel.
The percentage of biodiesel in the fuel
must not exceed 5%, referred to as B5. Do not
refuel with gasoline. If the vehicle has been re‐
fueled with incorrect fuel such as gasoline, do
not start the engine; otherwise, there is a danger
of engine damage.◀
If you added the wrong fuel, contact the service
center.
The fuel filling neck is designed for refueling 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. Seite 248
