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.

Refueling
246
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.
System heating
In order to bring the system to operating tem-
perature after a cold start of the engine, the
automatic transmission
shifts into the next
higher gear at a later point.
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.
The reserve display appears approx.
1,000 miles/1,600 km before the end of the
tank.
As soon as the reserve display has
appeared in the inst rument panel, have
the diesel exhaust fluid refilled to prevent the
engine from being unable to restart. <
Diesel exhaust fluid at minimum
Even with a display of -- mls, the engine will
continue to run, provided that it is not switched
off, and all other operating requirements are
met, e.g. sufficient fuel. Do not drive until the displayed remaining
distance runs out. Otherwise, it may not
be possible to restart the engine. <
Incorrect fueling
The warning lamp lights up:
The reservoir has been filled with an
incorrect fluid.
Please contact your BMW Sports Activity Vehi-
cle Center.
Have diesel exhaust fluid refilled
Your BMW Sports Activity Vehicle Center refills
the diesel exhaust fluid as part of the regular
maintenance. If you adhe re to this maintenance
schedule, it is usually no t necessary to refill any
fluids between the maintenance dates.
Under certain circumstances, e.g. due to a par-
ticularly sporty driving st yle or operation of the
vehicle at high altitudes, it may be necessary to
refill fluids betwee n 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.
You can have the fluid refilled by a BMW Sports
Activity Vehicle Center.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, at temper-
atures below +23 7/–5 6, it may also be
necessary to refill the diesel exhaust fluid
between the regular maintenance dates.
If the fluid needs to be re filled, this will be indi-
cated with the reserve display in the instrument
panel, refer to page 246.<

Maintenance
BMW maintenance system
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, a complete dealer service history
will prove to be an asset of inestimable value.
CBS Condition Based Service
Sensors and special algo rithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Contro l Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page 82:
> Engine oil
> Brake pads, front and rear separately
> Brake fluid
> Vehicle check >
Legally mandated inspections depending
on local regulations
Service data in remote control
Your vehicle stores the information required for
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote co ntrol, your BMW Service
Advisor can suggest precisely the right array of
service procedures for yo ur own individual vehi-
cle. You should therefore hand over the remote
control you last used to drive to the BMW Ser-
vice Advisor when you take your vehicle in for
service.
Make sure the date is set correctly, refer
to page 89, otherwise the effectiveness
of CBS Condition Based Service is not
ensured. <
