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 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.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines 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 cosolvent, 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 stalling problems
especially under certain 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 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 5Ξ, 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.<
In the event the ultra-low sulfur diesel
nozzle cannot be fully inserted into the
fuel filler neck, please contact BMW Roadside
Assistance for instructions on how to add fuel.
For more information on BMW Roadside Assis-
tance, refer to page274.<
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 filling
stations during this time of year. The standard
fuel filter heating prevents the supply of fuel
from stalling during driving.
Refueling
236 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 catalytic converter, a chem-
ical reaction occurs that minimizes nitrogen
oxides.
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 instrument 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.

Refilling BMW diesel exhaust fluid
1.Set bottle into place and rotate until it
comes into contact with the stop, refer to
arrow.
2.Press bottle down, refer to arrow.
The reservoir of the vehicle is filled.
3.The reservoir is full when the fill level in the
bottle stops changing. It is not possible to
overfill.
Pull bottle back, refer to arrow, and unscrew
it.
Closing reservoir
After the reservoir is filled, close it again with the
releasing tool.
After refilling diesel exhaust fluid
Incorrect fluid
After refilling with the incorrect fluid, e.g.
antifreeze for windshield wiper fluid, do
not start the engine because this could result in
a fire hazard.<
Contact your BMW Sports Activity Vehicle
Center.
Bottle disposal
You can have bottles for diesel exhaust
fluid properly disposed of at your BMW
Sports Activity Vehicle Center.
Only dispose of empty bottles in your house-
hold garbage if the local legal regulations permit
it.<
Reserve display
After refilling, the reserve continues to appear
after the engine is restarted. After the vehicle
has been driven for a few more minutes, this
display will disappear.
Wheels and tires
250 Tire Pressure Monitor cannot detect a flat tire,
refer to page101. Your BMW Sports Activity
Vehicle Center will be happy to advise you on
this subject.
Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Special characteristics of winter tires
BMW recommends using winter tires for opera-
tion on winter road or at temperatures below
+457/+76. Although all-season M+S tires
provide better winter traction than summer
tires, they generally fail to provide the same lev-
els of cold-weather performance as winter tires.
Paying attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
Even with tires of the same size, BMW
recommends that you not rotate the front
tires to the rear or vice versa as this can nega-
tively affect handling characteristics.
When the vehicle is equipped with different
tires sizes
*, rotating tires from one axle to the
other is not permitted.<
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Your BMW Sports Activity Vehicle Center
can provide you with this information.
BMW X5: use is only permitted in pairs on the
rear wheels with tires of the size:
>255/55 R 18
>255/50 R 19
BMW X6: it is only permissible to use snow
chains in pairs, on the 255/50 R 19 rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor
*, as otherwise
incorrect displays can occur.
When you are driving with snow chains, it can
be beneficial to activate DTC briefly, refer to
page96.<

Socket for OBD Onboard
Diagnostics interface
The chief components that make up the emis-
sions content can be checked by a device that
uses the OBD socket.
This socket is located to the left on the driver's
side, on the underside of the instrument cluster
under a cover.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. Continued driving is possible.
Have the vehicle checked as soon as possible.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case, you should reduce your speed and
proceed to the nearest BMW Sports Activity
Vehicle Center. Heavy engine misfiring causes
serious damage to the emission-relevant com-
ponents, especially the catalytic converter,
within a short time.
The warning lamp lights up if the fuel
cap has not been properly tightened
and the OBD system detects the
escape of fuel vapors. Check that the fuel cap is
correctly seated and tighten it until you hear a
clearly audible click.
Data memory
Your vehicle records data on vehicle operation,
malfunctions and user settings. These data are
stored in the vehicle and in part in the remote
control and can be read out by suitable devices
during service, for example. The read data are
used to assist in servicing and repairing your
vehicle or for the optimization and continued development of vehicle functions. In addition, if
you signed a service contract for Assist, certain
vehicle data can be sent directly from the vehi-
cle to facilitate the desired services.

Steam cleaners/high-pressure
cleaning jets
When using steam cleaners or high-pres-
sure cleaning jets, make sure to maintain
a sufficient distance and stay below a maximum
temperature of 1407/606.
Insufficient distance or excessive pressure or
temperature can damage parts of the vehicle or
can result in water penetration. Follow the oper-
ating instructions for the high-pressure clean-
ing jets.<
Do not spray the sensors and cameras,
e.g. of Park Distance Control, Top View,
or rear view camera, with high-pressure clean-
ers for long periods and keep the spray nozzle
at least 12 in/30 cm away from them.<
Hand washing
When washing the vehicle by hand, use plenty
of water and car washing shampoo. Clean the
vehicle with gentle pressure using a sponge or a
washing brush.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unwanted wiper operation.<
Follow local guidelines for washing vehi-
cles by hand.<
Headlamps
Do not rub dry and never use abrasives or
strong solvents to clean the covers.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with plenty of
water.
Use a window de-icer to remove accumulated
ice and snow, not a scraper.
Windows
Use a glass cleaner to clean the inside and out-
side surfaces of the windows and the glass sur-
faces of the mirrors.
Do not use quartz-containing cleansers
to clean glass surfaces of the mirrors.<
Caring for the vehicle finish
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggressive substances.
Regionally occurring environmental factors can
affect and damage vehicle finish. It is therefore
important to tailor the frequency and extent of
your car care accordingly.
Immediately remove particularly aggressive
substances such as spilled fuel, oil, grease,
brake fluid, tree resin, or bird droppings; other-
wise, they may damage your paint.
Repairing paint damage
Repair stone damage or scratches imme-
diately, depending on the severity of the
damage, to prevent the formation of rust.<
BMW recommends having paint damage pro-
fessionally repaired using Genuine BMW finish
materials in accordance with factory guidelines.
Waxing
Sealant is required when water no longer beads
on the clean surface of the paint. Use only prod-
ucts that contain carnauba wax or synthetic wax
to seal your finish.
Rubber gaskets
Treat only with water or a rubber care product.
To avoid noise or damage, do not use
products that contain silicone to care for
rubber gaskets.<
Chrome components
Particularly after exposure to road salt, thor-
oughly cleanse parts like the radiator grille, door
handles, or window frames with plenty of water
with shampoo added to it. For additional treat-
ment, use chrome polish.
Alloy wheels
Depending on your system, braking can gener-
ate dust, which settles on the light-alloy wheels.
Remove this dust regularly with acid-free wheel
cleaner.
