FuelFuel recommendationVehicle equipment This 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 sys‐
tems.
When using the features and systems described
here, adhere to local regulations.
GasolineFor 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 recommended fuel
grades.
Recommended fuel grade
The manufacturer of your MINI recommends:▷AKI 91.▷John Cooper Works AKI 93.
Minimum fuel grade
The manufacturer of your MINI 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. Addition‐
ally, problems relating to drivability, starting
and stalling, especially under certain environ‐
mental conditions such as high ambient tem‐
perature 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 pur‐
chase gasoline from BP or Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled mainte‐
nance. ◀

sor housing in a vertical position.4.Unscrew the dust cap off of the valve of the
defective wheel and screw the filling hose 2
of the sealant bottle onto the valve.5.Ensure that the compressor is switched off.6.Insert connector 5 into the lighter socket/
socket in the passenger compartment, refer
to page 106.7.When the engine is running:
Switch on the compressor and let it run for
approx. 3 to 8 minutes to fill sealant into
the tire and achieve a tire inflation pressure
of approx. 1.8 bar/26 psi.
While sealant is being filled, the inflation
pressure may intermittently rise to approx.
5 bar/73 psi. Do not switch off the com‐
pressor in this phase.8.Switch off the compressor.
Do not allow the compressor to run too
long
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged. ◀
If an air pressure of 1.8 bar/26 psi is not
reached:
1.Unscrew the filling hose 2 from the wheel
and drive forward and back approx.
33 ft/10 m to evenly distribute the sealant
in the tire.2.Inflate the tire again using the compressor.If the inflation pressure of 1.8 bar/26 psi is still
not reached, the tire is too heavily damaged.
Contact the nearest service center.
Stowing the Mobility System1.Unscrew the filling hose 2 of the sealant
bottle from the wheel.2.Unscrew the compressor connection hose 6
from the sealant bottle.3.Connect the filling hose 2 of the sealant
bottle with the free connector on the seal‐
ant bottle.
This prevents left-over sealant from escap‐
ing from the bottle.4.Wrap the empty sealant bottle in suitable
material to avoid dirtying the cargo area.5.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Drive approx. 3.1 miles/5 km to evenly distrib‐
ute the sealant.
Do not exceed a speed of 50 mph/80 km/h. If
possible, do not drop below a speed of
10 mph/20 km/h.
Correcting the tire inflation pressure
1.After driving approx. 3.1 miles/5 km, or
about 10 minutes, stop in a suitable loca‐
tion.2.Screw the connection hose 6 of the com‐
pressor directly onto the tire valve.3.Insert the connector 5 into the power
socket in the passenger compartment.4.Correct the tire inflation pressure to
1.8 bar/26 psi. When the engine is running:▷To increase the inflation pressure:

General information
Engine oil consumption depends on the driving
style and the conditions of use. A highly sporty
driving style, for example, results in considera‐
bly higher engine oil consumption.
Therefore, regularly check the engine oil level
after refueling.
Checking the oil level with a dip stick1.Park the vehicle on level ground when the
engine is at operating temperature, i.e., af‐
ter driving continuously for at least
6 2 miles/10 km.2.Switch the engine off.3.After approx. 5 minutes, pull out the dip
stick and wipe it off with a lint-free cloth,
paper towel, etc.4.Carefully insert the dip stick all the way into
the measuring tube and pull it out again.The oil level must be between the two
marks on the dip stick.
The oil quantity between the two marks on the
dip stick equals approx. 1 US quart/1 liter.
Do not exceed the high mark.
Do not exceed the high mark of the dip
stick. Overfilling oil damages the engine. ◀

Socket for OBD Onboard
Diagnosis
Socket for Onboard Diagnosis
The socket for Onboard Diagnosis may
only be used by the service center, by work‐
shops that operate according to the specifica‐
tions of the vehicle manufacturer with appro‐
priately trained personnel, and by other
authorized persons. Otherwise, its use may
lead to vehicle malfunctions. ◀
Primary components in the vehicle emissions
can be checked via the OBD socket using a de‐
vice.
Emissions The warning lamps light up. The vehicle
is producing higher emissions. You can
continue your journey, but moderate
your speed and exercise due caution. Have the
vehicle checked as soon as possible.
Under certain circumstances, one of the lamps
flashes or lights up continuously. This indicates
that there is excessive misfiring or a malfunc‐
tion in the engine. If this happens, reduce the
vehicle speed and drive to the next service cen‐
ter promptly. Serious engine misfiring within a
brief period can seriously damage emission
control components, in particular the catalytic
converter. In addition, the mechanical engine
components may become damaged.
If the fuel filler cap is not properly tight‐
ened, the OBD system may conclude
that fuel vapor is escaping; this will cause a dis‐
play to light up. If the filler cap is then tight‐
ened, the display should go out in a few days.Seite 176MOBILITYMaintenance176

driving characteristics could result, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced. ◀
Only mount one compact wheel
Only one compact wheel may be
mounted. Restore the wheels and tires to their
original size as quickly as possible. Failure to do
so is a safety risk. ◀
Check the tire inflation pressure at the next op‐
portunity and correct it if necessary. Replace
the defective tire as soon as possible and have
the new wheel balanced.
Preparing wheel change
Observe the safety precautions regarding flat
tires, refer to page 166.
Additional safety precautions in the event
of a wheel change
Change the wheel only on a level, firm surface
which is not slippery.
The vehicle or the jack could slip to the side if
you attempt to raise the vehicle on a soft or
slippery surface, snow, ice, tiles, etc. Do not use
a wooden block or similar object as a support
base for the jack, as this would prevent it from
extending to its full support height and reduce
its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it
is supported by the jack. ◀1.Place the folding wheel chock behind the
front wheel of the other vehicle side; if the
vehicle is on an incline, place it in front of
this wheel. If the vehicle is parked on a
steep incline, additionally secure the vehi‐
cle against rolling.2.Expose the lug bolts if necessary.3.Loosen the lug bolts a half turn.Jacking up vehicle
The vehicle jack is designed for changing
wheels only.
The vehicle jack is designed for changing
wheels only. Do not attempt to raise another
vehicle model with it or to raise any load of any
kind. To do so could cause accidents and per‐
sonal injury. ◀
1.Position the vehicle jack at the jacking point
closest to the wheel.
The entire surface of the jack base must
rest on the ground vertically beneath the
jacking point.2.Guide the jack head into the rectangular re‐
cess of the jacking point when cranking up.3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting the compact wheel
1.Unscrew the lug bolts and remove the
wheel.2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.Seite 186MOBILITYReplacing components186
