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.

Have diesel exhaust fluid refilled
Your BMW Sports Activity Vehicle Center refills
the diesel exhaust fluid as part of the regular
maintenance. If you adhere to this maintenance
schedule, it is usually not necessary to refill any
fluids between the maintenance dates.
Under certain circumstances, e.g. due to a par-
ticularly sporty driving style or operation of the
vehicle at high altitudes, it may be necessary 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.
You can have the fluid refilled by a BMW Sports
Activity Vehicle Center.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it may be
necessary to replenish the level of diesel
exhaust fluid at temperatures below +237/
-56 even between the regular maintenance
intervals.
If the fluid needs to be refilled, this will be indi-
cated with the reserve display in the instrument
panel, refer to page236.<
Only refill the diesel exhaust fluid
yourself in exceptional circumstances
In order to get your vehicle to reach the nearest
BMW Sports Activity Vehicle Center, you may
refill the diesel exhaust fluid yourself, making
sure to heed the warning notices.
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 reservoir, pungent
smelling vapors can escape. Before 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 irrita-tion, e.g. due to inadvertent contact with the
eyes.
If eye irritation occurs, immediately rinse eyes
with ample water and contact a doctor if neces-
sary.
If diesel exhaust fluid comes into contact with
surfaces of your vehicle, rinse the affected sur-
faces with water or else damage may occur.
Keep diesel exhaust fluid out of reach of chil-
dren.<
Suitable diesel exhaust fluid
>Preferred: BMW Diesel Exhaust Fluid.
This bottle and its special adapter permit

Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact tire
*: at least twice a month and before
starting long trips. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect tire pressures, a condition that can not only
compromise your vehicle's driving stability, but
also lead to tire damage and the risk of an acci-
dent. Do not drive with depressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page100, or reset the Tire Pressure Monitor,
refer to page102.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW Sports Activ-
ity Vehicle Center.
ing:
>Tire sizes of your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. of
100 mph/160 km/h to achieve optimum driving
comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages. Oth-
erwise tire damage and accidents could
occur.<
