engine BMW X3 2017 Workshop Manual

HillsWARNING
Light but consistent brake pressure can
lead to high temperatures, brakes wearing out
and possibly even brake failure. There is risk of
an accident. Avoid placing excessive stress on
the brake system.◀
WARNING
In idle state or with the engine switched
off, safety-relevant functions are restricted or
not available anymore, e.g., braking effect of
the engine or braking force and steering sup‐
port. There is risk of an accident. Do not drive
in idle state or with the engine switched off.◀
Drive long or steep downhill gradients in the
gear that requires least braking efforts. Other‐
wise the brakes may overheat and reduce
brake efficiency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if needed.
Brake disc corrosion
Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by the fol‐
lowing circumstances:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion will built up when the maximum
pressure applied to the brake pads during
braking is not reached - thus discs don't get
cleaned.
Corrosion buildup on the brake discs will cause
a pulsating effect on the brakes in their re‐
sponse - generally that cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops collecting under‐
neath the vehicle.
Driving on racetracksHigher mechanical and thermal loads during
racetrack operation lead to increased wear.
This wear is not covered by the warranty. The
vehicle is not designed for motorsports com‐
petitive use.Seite 185Things to remember when drivingDriving tips185

Saving fuelVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove roof-mounted luggage racks which
are no longer required following use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.Seite 189Saving fuelDriving tips189
Online Edition for Part no. 01 40 2 969 976 - II/16

Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Start‐
ing with the 2nd gear, accelerate rapidly. When
accelerating, shift up before reaching high en‐
gine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
If necessary, observe the gear shift indicator of
the vehicle, refer to page 91.
Use coasting
When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
For going downhill take your foot off the accel‐
erator 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, for
example, at traffic lights, railroad crossings or
in traffic congestion.
Auto Start/Stop function
The Auto Start/Stop function of the vehicle au‐
tomatically 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.
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.
Switch off these functions if they are not
needed.
The ECO PRO driving program supports the
energy conserving use of comfort features.
These functions are automatically deactivated
partially or completely.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and service life.
BMW recommends that maintenance work be
performed by a BMW dealer’s service center.
For information on the BMW Maintenance
System, refer to page 226.
ECO PRO
The concept
ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort features, e.g. the cli‐
mate control output, are adjusted.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
the D selector lever position. The vehicle con‐
tinues traveling with the engine idling to re‐
duce fuel consumption. Selector lever position
D remains engaged.Seite 190Driving tipsSaving fuel190

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 selector lever position D is set. The
vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Information Coasting is a component of the ECO PRO driv‐
ing 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 proactive driving style helps the driver to use
the function as often as possible and supports
the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷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
the following conditions are met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.

Fuel recommendation General information
Depending on the region, many gas stations
sell fuel that has been customized to winter or
summer conditions. Fuel that is available in
winter helps make a cold start easier, for exam‐
ple.
Information ATTENTION
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, e.g., poor engine start-up be‐
havior, poor handling and/or poor performance.
There is a risk of damage to property. In case
of engine problems, switch gas stations or use
a brand name fuel with a higher octane rat‐
ing.◀
Gasoline
General information For the best fuel efficiency, the gasoline
should be sulfur-free or very low in sulfur con‐
tent.
Fuels that are marked on the gas pump as con‐
taining metal must not be used.Fuels with a maximum ethanol content of
10 %, i. e., E10, may be used for refueling.
Ethanol should meet the following quality
standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each
case.
Information ATTENTION
Do not press the Start/Stop button after
refueling with the wrong fuel. Furthermore, the
catalytic converter is permanently damaged.
There is a risk of damage to property. Do not
refuel or add the following in the case of gaso‐
line engines:▷Leaded gasoline.▷Metallic additives, e.g., manganese or iron.
Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.◀
ATTENTION
Incorrect fuels can damage the fuel sys‐
tem and the engine. There is a risk of damage
to property. Do not use a fuel with a higher
ethanol percentage than recommended or one
with other types of alcohol, e.g., M5 to M100.◀
ATTENTION
Fuel that does not comply with the mini‐
mum quality can compromise engine function
or cause engine damage. There is a risk of
damage to property. Do not fill with fuel that
does not comply with the minimum quality.◀

CAUTION
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 Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled main‐
tenance.◀
Recommended fuel grade
BMW recommends AKI 91.
Minimum fuel grade
BMW recommends AKI 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 effect on the engine life.
Diesel
Information ATTENTION
Do not press the Start/Stop button after
refueling with the wrong fuel. There is a risk of
damage to property.
Observe the following for diesel engines:▷Use only Ultra-Low Sulfur Diesel. Maxi‐
mum content of biodiesel: 5 %, B5.▷Do not use rapeseed methyl ester RME.▷Do not use biodiesel above 5 %, B5.▷Do not use gasoline.▷No diesel additives.Do not press the Start/Stop button after refuel‐
ing with the wrong fuel. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.◀
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 gas‐
oline. If you do fill the tank with the wrong fuel,
e.g., gasoline, do not start the engine as this
may damage the engine.
In the case of incorrect refueling, contact a
dealer’s service center or another qualified
service center or repair shop or Roadside As‐
sistance.
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 additional information regarding Roadside
Assistance, refer to Owner's Manual for Navi‐
gation, Entertainment and Communication.Seite 201FuelMobility201

BMW Advanced Diesel
The concept BMW Advanced Diesel reduces nitrogen ox‐
ides in the diesel emissions by injecting diesel
exhaust fluid into the exhaust system. A chem‐
ical reaction takes place inside the catalytic
converter that minimizes nitrogen oxides.
The vehicle has a tank system that can be refil‐
led.
To be able to start the engine as usual, there
must be an adequate diesel exhaust fluid.
Warming up the system
In order to warm the engine up to its operating
temperature after a cold start, the Steptronic
transmission may subsequently shift up to the
next higher gear.
Displays in the instrument cluster
Reserve indication This display in the instrument cluster provides
information about the distance that can still be
driven with the current reserve level.
Do not continue driving to the limit of the re‐
maining travel distance. It is not possible to re‐
start the engine after switching it off.▷Lamp white: refill with diesel
exhaust fluid at the next op‐
portunity.▷Lamp yellow: not enough
diesel exhaust fluid present.
The remaining range is dis‐
played in the instrument
cluster. Immediately refill
with diesel exhaust fluid.
Diesel exhaust fluid on minimum
▷The remaining range is dis‐
played in the instrument
cluster: add diesel exhaust
fluid. The engine will con‐
tinue to run as long as it isnot switched off and all
other operating conditions
are satisfied; sufficient fuel,
for example.
System malfunction
A Check Control message is displayed when
there is a system not working.
Have the diesel exhaust fluid
replenished
BMW recommends that diesel exhaust fluid be
added by the dealer’s service center within the
course of regular maintenance.
In addition it may be necessary to have the
fluid replenished several times under particular
circumstances, for example, if the vehicle is
driven in a particularly sporty style or if it is
driven at high altitudes.
The diesel exhaust fluid must be replenished
as soon as the reserve display appears in the
instrument cluster to avoid not being able to
restart the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible
that the diesel exhaust fluid may also need to
be replenished between regular maintenance
appointments if it is exposed to temperatures
under + 23 ℉/- 5 ℃. In this case, add diesel ex‐
haust fluid only immediately before driving off.
At temperatures below + 12 ℉/- 11 ℃, the fill‐
ing level cannot be measured in some cases.
Replenishing diesel exhaust fluid
yourself in exceptional cases
General information You can replenish diesel exhaust fluid yourself
in exceptional cases, for example, to get to
your scheduled service.
