Fuel specifications
Fuels that are labeled at the pump as containing
metal may not be used.
Do not fill the tank with leaded gasoline or
gasoline that contains metal additives,
such as manganese or iron; otherwise, long term
damage to the catalytic converter or other com-
ponents may result.
Do not fill the tank with E85, i.e. fuel containing
85 % ethanol, nor with FlexFuel. Otherwise, the
engine and fuel supply system will be dam-
aged. <
Required fuel
Super premium gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI rating is:
> Cooper S, John Cooper Works: 89
> Cooper: 87
If you use gasoline with this minimum AKI rating,
the engine may produce knocking sounds when
starting at high outsid e temperatures. This has
no effect on the engine life.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the
engine could be damaged. <
Use high-quality brands
Field experience has indicated significant differ-
ences in fuel quality: volatility, composition,
additives, etc., among ga solines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of cosolvent, will not void
the applicable warranties with respect to defects
in materials or workmanship. The use of poor-quality fuels may result in
drivability, starting
and stalling problems
especially under certain environmental condi-
tions such as high am bient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recogn ized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in un scheduled maintenance. <

Socket for On-Board
Diagnosis OBD
The primary components that make up the
emissions can be checked by a device via the
OBD socket.
Emissions
The warning lamps come on. The vehicle
is producing higher emissions. You can
continue your journey, but moderate
your speed and exercise due caution.
Have the car checked as soon as possible.
Under certain circumstances, one of the lamps
will flash or light up continuously. This indicates
excessive misfiring or a malfunction in the
engine. If this happens, reduce your speed and
visit the nearest MINI dealer as soon as possible.
Severe misfiring can quickly lead to serious dam-
age of emissions-related components, espe-
cially the catalytic converter. In addition,
mechanical engine components can become
damaged.
If the fuel filler cap is not properly tight-
ened, the OBD system may conclude
that fuel vapors are escaping, causing an
indicator to light up. If the filler cap is then tight-
ened, the indicator should go out within a few
days.
Data memory
Your vehicle displays data about the operation,
malfunctions, and user settings. These data are
stored in the vehicle and can be partly stored in
the remote control; the da ta can be read b y su it-
able devices, in particular at your service center.
The data read out are used for supporting the
service processes and repair or for optimization
and development of vehicle functions.
