engine BMW X6 2013 E71 Workshop Manual

FuelVehicle equipmentThis 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
systems.
Fuel quality
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.
Only refuel with lead-free gasoline with‐
out 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.◀
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
CAN: CGSB-3.511–xx
xx: always adhere to the currently applicable
standard.
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
system.◀The engine is knock controlled. Therefore, you
can refuel with different gasoline qualities.
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 speci‐
fied minimum quality; otherwise, the engine
may not run properly.◀
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.
Minimum fuel grade
The use of poor-quality fuels may result
in harmful engine deposits or damage. Addi‐
tionally, problems relating to drivability, start‐
ing and stalling, especially under certain envi‐
ronmental conditions such as high ambient
temperature and high altitude, may occur.
If drivability problems are encountered, we rec‐
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI num‐
ber — for a few tank fills. To avoid harmful en‐
gine deposits, it is highly recommended to
purchase gasoline from BP or Top Tier retail‐
ers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
Diesel
Ultra-Low Sulfur Diesel
The engine of your BMW is designed for diesel
with a low sulfur content:Seite 270MobilityFuel270
Online Edition for Part no. 01 40 2 918 395 - III/13

Ultra-low sulfur diesel ASTM D 975-xx.
xx: always adhere to the currently applicable
standard.
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 dan‐
ger of engine damage.◀
If you added the wrong fuel, contact the serv‐
ice center.
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 die‐
sel nozzle.
In the event the Ultra-Low Sulfur Diesel fuel
cannot 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 308.
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.◀BMW X5 with BMW
Advanced Diesel
The concept
BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel exhaust of your vehicle by in‐
jecting the reducing agent diesel exhaust fluid
into the exhaust line. In the catalytic converter,
a chemical reaction occurs that minimizes ni‐
trogen 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 au‐
tomatic 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 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
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.
No engine start
Do not drive until the displayed remain‐
ing 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 in‐
correct fluid.
Please contact your service center.
Have diesel exhaust fluid refilled This exhaust fluid is refilled by your service
center during regular maintenance. If you ad‐
here to this maintenance schedule, it is usually
not necessary to refill any fluids between the
maintenance dates.
Under certain circumstances, for example, due
to a particularly sporty driving style or opera‐
tion 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 service cen‐
ter.
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
between the regular maintenance dates.
If the fluid needs to be refilled, this will be indi‐
cated with the reserve display in the instru‐
ment cluster, refer to page 271.
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.
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 instruc‐
tions 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 suffi‐
cient ventilation. After handling diesel exhaust
fluid, wash hands thoroughly. Failure to do so
may lead to irritation, for instance, due to inad‐
vertent contact with the eyes. If eye irritation
occurs, immediately rinse eyes with ample wa‐
ter 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.◀
