Efficiency displayDisplay in the instrument clusterDisplay in the instrument display
A mark in the efficiency display informs about
the current driving style.
Mark in the area of arrow 1: display of the en‐
ergy recovered by coasting or when braking.
Mark in the area of arrow 2: display when ac‐
celerating.
Your driving style's efficiency is shown by the
bar's color:
▷Blue display: efficient driving style as long
as the mark moves within the blue range.▷Gray display: adjust driving style, e. g. by
backing off the accelerator pedal.
The display switches to blue as soon as all
conditions for fuel-efficiency-optimized driving
are met.
ECO PRO tip, driving tip The arrow indicates that the driving
style can be adjusted to be more fuel
efficient by backing off the accelerator for in‐
stance.
Note The efficiency display and ECO PRO tips in theinstrument cluster appear when the ECO PRO
display is activated.

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.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 180, 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 proactively driving style helps the driver to
use the function as often as possible and sup‐
ports 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.
The driving status Coast can be influenced
with the shift paddles.

RefuelingVehicle features and options
This 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.
Hints Observe the fuel recommendation, refer to
page 190, prior to refueling.
Refuel promptly
Refuel no later than at a range of
30 miles/50 km or engine operation might fail
and damage might occur.◀
Fuel lid Opening1.Briefly press the rear edge of the fuel filler
flap.2.Turn the tank lid counterclockwise.3.Place the tank lid in the bracket attached to
the fuel filler flap.
Closing
1.Fit the lid and turn it clockwise until you
clearly hear a click.2.Close the fuel filler flap.
Do not pinch the retaining strap
Do not pinch the retaining strap attached
to the lid; otherwise, the lid cannot be closed
properly and fuel vapors can escape.◀
Manually unlocking fuel filler flap In the event of an electrical malfunction, e.g.
The release is located in the trunk.

symbol. This releases the fuel filler flap.
Observe the following when
refueling
The fuel tank is full when the filler nozzle clicks
off the first time.
Do not overfill the fuel tank
Do not overfill the fuel tank; otherwise
fuel may eslide, causing harm to the environ‐
ment and damaging the vehicle.◀

Fuel recommendation Note General fuel quality
Even fuels that conform to the specifica‐
tions can be of low quality. This may cause en‐
gine problems, for instance poor engine start-
up behavior, poor handling and/or poor
performance. Switch gas stations or use a
brand name fuel with a higher octane rating.◀
Gasoline 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.
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, as this can cause permanent damage to
the catalytic converter and other compo‐
nents.◀
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–xx
xx: comply with the current standard in each
case.
Do not use a fuel with a higher percent‐
age of ethanol
Do not use a fuel with a higher ethanol per‐
centage than recommended or one with other
types of alcohol, e.g. M5 to M100; otherwise
this could damage the engine and fuel supply
system.◀
Recommended fuel grade 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‐Seite 190MobilityFuel190

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.◀Seite 191FuelMobility191
