Fuel
The engine is knock controlled. Therefore, you
can refuel with different gasoline qualities.
Vehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
Recommended fuel quality
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
Minimum fuel grade
Do not fill up with fuel below the specified
minimum quality; otherwise, the engine may not
run properly.◀
Fuel quality
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 effect on the engine life.
Gasoline
For the best fuel economy, the gasoline should
be sulfur-free or very low in sulfur content.
Do not use fuels that are labeled at the fuel pump
as containing metals.
Minimum fuel grade
The use of poor-quality fuels may result in
harmful engine deposits or damage. Addition‐
ally, problems relating to drivability, starting and
stalling, especially under certain environmental
conditions such as high ambient temperature
and high altitude, may occur.
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.◀
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI number
— for a few tank fills. To avoid harmful engine
deposits, it is highly recommended to purchase
gasoline from BP or Top Tier retailers.
Fuels with a maximum ethanol content of 10 %,
i.e., E10, may be used for refueling.
The ethanol should fulfill the following quality
standards:
US: ASTM 4806–xx
Failure to comply with these recommendations
may result in the need for unscheduled mainte‐
nance.◀
CAN: CGSB-3.511–xx
xx: always adhere to the currently applicable
standard.
Do not refuel with ethanol E85
Diesel
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.◀
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-xx.
264
Fuel
Mobility
xx: always adhere to the currently applicable
standard.
BMW X5 with BMW Advanced
Diesel
Only refuel with ultra-low sulfur diesel.
The concept
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.◀
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 catalytic converter, a chem‐
ical reaction occurs that minimizes nitrogen ox‐
ides.
If you added the wrong fuel, contact the service
center.
In order to be able to start the engine in the usual
way, there must be a sufficient supply of diesel
exhaust fluid in the separate reservoir.
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.
System heating
In order to bring the system to operating tem‐
perature after a cold start of the engine, the au‐
tomatic transmission shifts into the next higher
gear at a later point.
In the event the Ultra-Low Sulfur Diesel fuel can‐
not be fully inserted into the fuel filler neck,
please contact BMW Roadside Assistance for
instructions on how to add fuel. For more infor‐
mation on BMW Roadside Assistance, refer to
page 301.
Reserve display
A display in the instrument panel informs you
about the remaining distance can be covered
with the amount of fuel currently in the tank.
Winter diesel
To ensure that the diesel engine remains op‐
erational in the winter, use winter diesel.
It is available at gas stations during winter
months.
The standard fuel filter heating prevents the
supply of fuel from stalling during driving.
Do not use diesel additives
Do not use additives, including gasoline;
otherwise, engine damage may occur.◀
The reserve display appears approx.
1,000 miles/1,600 km before the tank is empty.
As soon as the reserve display has appeared in
the instrument panel, have the diesel exhaust
fluid refilled to prevent the engine from being
unable to restart.

Diesel exhaust fluid at minimum
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it may be neces‐
sary to replenish the level of diesel exhaust fluid
at temperatures below +23 ℉/ -5 ℃, even be‐
tween the regular maintenance dates.
If the fluid needs to be refilled, this will be indi‐
cated with the reserve display in the instrument
cluster, refer to page 265.
Only refill the diesel exhaust fluid
yourself in exceptional circumstances
To be able to reach the nearest service center
with your vehicle, you may refill the diesel ex‐
haust fluid yourself, making sure to heed the
warning notices specified below.
Even with a display of -- mls, the engine will con‐
tinue to run, provided that it is not switched off,
and all other operating requirements are met,
e.g. sufficient fuel.
No engine start
Do not drive until the displayed remaining
distance runs out. Otherwise, it may not be pos‐
sible to restart the engine.◀
Handling diesel exhaust fluid
Do not allow diesel exhaust fluid to come
into contact with you. This can lead to skin and
eye irritation. Wear protective goggles and
gloves as needed. Follow the safety instructions
on the bottle. When opening the bottle or res‐
ervoir, pungent smelling vapors can escape. Be‐
fore refilling, close the vehicle completely so
that the vapors do not get into the interior of the
vehicle. When handling diesel exhaust fluid in
enclosed spaces, make sure to have sufficient
ventilation. After handling diesel exhaust fluid,
wash hands thoroughly. Failure to do so may
lead to irritation, for instance, due to inadvertent
contact with the eyes. If eye irritation occurs,
immediately rinse eyes with ample water and
contact a doctor if necessary. If diesel exhaust
fluid comes into contact with surfaces of your
vehicle, rinse the affected surfaces with water or
else damage may occur. Keep diesel exhaust
fluid out of reach of children.◀
Incorrect fueling
The warning lamp lights up:
The reservoir has been filled with an in‐
correct fluid.
Please contact your service center.
Have diesel exhaust fluid refilled
This exhaust fluid is refilled by your service cen‐
ter during regular maintenance. If you adhere to
this maintenance schedule, it is usually not nec‐
essary to refill any fluids between the mainte‐
nance dates.
Under certain circumstances, for example, due
to a particularly sporty driving style or operation
of the vehicle at high altitudes, it may be neces‐
sary to refill fluids between maintenance dates.
As soon as the reserve display has appeared in
the instrument panel, have the diesel exhaust
fluid refilled to prevent the engine from being
unable to restart.
Suitable diesel exhaust fluid
▷
Preferred: BMW Diesel Exhaust Fluid. This
bottle and its special adapter permit con‐
venient refilling with diesel exhaust fluid.
You can have the fluid refilled by a service cen‐
ter.
