engine BMW X5 2014 F15 Repair Manual

On a downhill gradient, take your foot off the
accelerator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during
longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Auto Start/Stop function The Auto Start/Stop function of your vehicle
automatically switches off the engine during a
stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
Using this system can cause certain compo‐
nents of the vehicle to become worn prema‐
turely.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,
road conditions, maintenance or environmental
factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
reduce the range, especially in city and stop-
and-go traffic.
Therefore, switch off these functions if they
are not actually needed.
The ECO PRO driving program supports the
energy conserving use of comfort functions.
These functions are automatically deactivated
partially or completely.Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 229.
ECO PRO
The concept ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort functions, e. g. the
climate control output, are adjusted.
In the instrument display, the extension of the
range achieved by this can be displayed as a
bonus range.

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when transmission position D is engaged.
The vehicle continues traveling with the engine
idling to reduce fuel consumption. Transmis‐
sion position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as the brake or accelerator pedal is
depressed, the engine is automatically coupled
to the transmission again.
Hints Coasting is a component of the ECO PRO, re‐
fer to page 198, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A forward-looking driving style helps the driver
to use the function as often as possible and supports the fuel-conserving effect of coast‐
ing.
Safety mode
The function is not available if one of the fol‐ lowing conditions is satisfied.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if

Fuel recommendation Note General fuel quality
Even fuels that conform to the specifica‐
tions can be of low quality. Switch gas stations
or use fuel from brand name producers having
a higher octane level; otherwise, engine prob‐
lems, such as poor engine starting perform‐
ance, poorer handling characteristics or driving
performance may occur.◀
Gasoline For the best fuel economy, the gasoline should
be sulfur-free or very low in sulfur content.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.
Refuel only with unleaded gasoline with‐out metallic additives.
Do not refuel with any leaded gasoline or gaso‐
line with metallic additives, e. g. manganese or
iron, or permanent damage to the catalytic
converter and other components.◀
Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.
Ethanol should satisfy the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xxxx: comply with the current standard in each
case.
Do not refuel with Ethanol above the
maximum Ethanol proportion
Do not refuel with Ethanol above the maximum
Ethanol proportion, that is, refueling with fuel
that contains more than 10 % Ethanol, flex fuel
or other alcohols; otherwise, damage to the
engine and fuel supply could result.◀
Gasoline quality BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 89.
Minimum fuel grade
Do not use any gasoline below the mini‐
mum fuel grade as this may impair engine per‐
formance.◀
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.
Fuel quality
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.Seite 206MobilityFuel206
Online Edition for Part no. 01 40 2 926 740 - X/13

Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
Diesel
Low-Sulfur Diesel
The engine of your BMW is designed for diesel
with low sulfur content:
Ultra-Low Sulfur Diesel ASTM D 975-xx.
xx: comply with the current standard in each
case.
Use only Ultra-Low Sulfur Diesel.
The fraction of biodiesel in the fuel must
not exceed 5 %, referred to as B5. Do not use
gasoline. If you do fill the tank with the wrong
fuel, e.g., gasoline, do not start the engine as
this may damage the engine.◀
After adding the wrong fuel, contact your serv‐
ice center or roadside assistance.
If the fuel pump nozzle does not fit in the filler
pipe of your BMW, please check to ensure that you are refueling at a diesel fuel pump that is
equipped with a diesel fuel pump 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 240.
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 fuel filter heating system, included as a
standard feature, prevents disruption of the
fuel supply while driving.
Do not add any diesel additives
Do not add additives, including gasoline;
otherwise, engine damage may occur.◀
BMW Advanced Diesel
The concept BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel emissions by injecting diesel
exhaust fluid reducing agent into the exhaust
system. A chemical reaction takes place inside
the catalytic converter that minimizes nitrogen
oxides.
The vehicle has two tanks, the active tank and
the passive tank. The active tank can be refil‐
led in the engine compartment. The passive
tank is refilled by the service center.
To be able to start the engine as usual, there
must be an adequate reducing agent.
Warming up the system
In order to warm the engine up to its operating
temperature after a cold start, the automatic
transmission may subsequently shift up to the
next higher gear.
Displays in the instrument cluster
Reserve display
This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.

the tank is filled with the incorrect fuel.
After adding the wrong fuel, contact your serv‐
ice center.
System defect
A Check Control message is displayed when
there is a system defect.
Have the diesel exhaust fluid
replenished
The reducing agent is added by the service
center within the context of regular mainte‐
nance. Provided you observe this maintenance
schedule, it is normally necessary to replenish
the fluid once between maintenance appoint‐
ments.
It may be necessary to have the fluid replen‐
ished several times under particular circum‐
stances, for example, if the vehicle is driven in
a particularly sporty style or if it is driven at
high altitudes.The reducing agent must be replenished as
soon as the reserve display appears in the in‐
strument cluster to avoid not being able to re‐
start the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible that reducing agent may also need to be re‐
plenished between regular maintenance ap‐
pointments if it is exposed to temperatures be‐
low + 23 ℉/- 5 ℃. In this case, add reducing
agent only immediately before starting to drive.
The need to replenish it is indicated by the Re‐
serve display in the instrument cluster.
At temperatures below + 12 ℉/- 11 ℃ the fill
level in some cases cannot be measured.
After adding reducing agent, the reserve dis‐
play is displayed only until the fill level can be
measured again.
Replenishing Diesel exhaust fluid
yourself in exceptional cases
You can replenish reducing agent yourself in
exceptional cases, e.g., to get to the service
center.
Avoid contact with Diesel exhaust fluid
Do not come into contact with the reduc‐
ing agent. Otherwise, skin or eye irritations
may result.◀
Handling Diesel exhaust fluid
When working with reducing agent in
closed spaces, ensure good ventilation. When
the bottle or container is opened, acrid smell‐
ing fumes may escape.◀
