REFUELINGThis gasoline is highly recommended.
However, you may also use gasoline with
less AKI. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI
rating, the engine may produce knocking
sounds when starting at high outside tem-
peratures. This has no effect on the engine
life.Use high-quality brandsField experience has indicated significant
differences in fuel quality: volatility, com-
position, additives, etc., among gasolines
offered for sale in the United States and
Canada. Fuels containing up to and includ-
ing 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 co-solvent, will not void the
applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may
result in driveability, starting and
stalling problems especially under certain
environmental conditions such as high
ambient temperature and high altitude.
Should you encounter driveability prob-
lems which you suspect could be related to
the fuel you are using, we recommend that
you respond by switching to a recognized
high-quality brand such as gasoline that is
advertised as Top Tier Detergent Gasoline.
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance.<

ENGINE OILMeasuring the oil level1. With the vehicle's engine at normal
operating temperature, i.e. after unin-
terrupted driving for at least 6 miles/
10 km, park the vehicle on a level surface
2. Switch off the engine
3. Pull the dipstick out after approx.
5 minutes and wipe it off with a lint-free
cloth, paper towel, or similar material
4. Carefully push the dipstick all the way
into the guide tube and pull it out again.
The oil level should be between the two
marks on the dipstick.
As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.
The oil volume between the two marks
MIN, MAX on the dipstick corresponds to
approx. 1.1 quarts/1 liter.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage
the engine. Only top up oil when the oil level has
dropped to just above the lower mark
of the dipstick. However, never allow the
level to drop below the lower mark.<
Add oil within the next 30 miles/
50 km, otherwise the engine could be
damaged.<
Always store oil, grease, etc., out of
reach of children. Comply with all
warning labels and information on lubri-
cant containers, otherwise health risks may
result.<
Oil changeHave the oil changed only by a MINI Dealer
or a workshop that has specially trained
personnel working in accordance with the
specifications of the MINI manufacturer.

ENGINE OIL COOLANTApproved engine oilsThe quality of the engine oil selected has
critical significance for the operation and
service life of an engine. Based on exten-
sive testing, the manufacturer of your MINI
approves only certain grades of engine oil.
Only use High Performance Synthetic Oil
approved by the manufacturer of your
MINI.
If MINI High Performance Synthetic Oil is
not available, you can add small quantities
of another synthetic oil in between oil
changes. Only use oils with a specification
of API SH or higher.
If you have any further questions
regarding MINI High Performance
Synthetic Oil or approved synthetic oils,
your MINI Dealer will be glad to advise
you.<
Do not use any oil additives, as they
could cause engine damage under
some circumstances. and is classified into SAE grades.
The correct SAE grade for your MINI is
determined by the climatic conditions of
the region in which you normally drive your
MINI.
Approved oils feature the SAE grades
5W-40 and 5W-30.<
These oils can be used for driving at all out-
side temperatures.
Do not open the cooling system when
the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of water and a coolant
additive. Not all commercially available
additives are suitable for your MINI. Your
MINI Dealer knows which additives are
suitable and will be glad to advise you.
Only use suitable additives, other-
wise the engine can be damaged. The
additives are hazardous to your health.<
Comply with the applicable environ-
mental laws regulating the disposal
of coolant additives.<

MINI MAINTENANCE SYSTEMThe MINI maintenance system helps main-
tain your vehicle's road safety and opera-
tional safety.
Please bear in mind that regular mainte-
nance is not only necessary for the safety of
your vehicle, but also plays a significant
role in maintaining the resale value of the
vehicle.
Service interval displayWhile conventional systems determine
maintenance intervals according to fixed
kilometer readings, the MINI Maintenance
System takes the vehicle's driving condi-
tions into account because not every mile is
the same as another in this respect.
From a maintenance standpoint,
60,000 miles/100,000 km accumulated
through short-distance driving cannot be
treated the same as 60,000 miles/
100,000 km accumulated through long-dis-
tance highway travel.
The condition-based MINI Maintenance
System includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual use of the vehicle
covers every kind of operating situation.
People who drive very little, i.e. much less
than 6,000 miles/10,000 km per year,
should have the engine oil changed at least
every 2 years since oil deteriorates over
time, regardless of use.
For more information on the service inter-
val display, refer to page69.
Service and Warranty Information
Booklet for US models, Warranty and
Service Guide Booklet for Canadian
models For additional information on maintenance
intervals and procedures, please refer to
the Service and Warranty Information
Booklet for US models or the Warranty and
Service Guide Booklet for Canadian models.
As a precaution against rust, it is advisable
to have the body checked for damage from
rocks or gravel at the same time, depending
upon operating conditions.
The manufacturer of your MINI rec-
ommends having maintenance and
repair work carried out only by a MINI
Dealer or a workshop that has specially
trained personnel working in accordance
with the specifications of the MINI manu-
facturer.
Make sure that maintenance work is con-
firmed with an entry in the Service and
Warranty Information Booklet for
US models or the Warranty and Service
Guide Booklet for Canadian models. These
entries are your proof that the vehicle has
received regular maintenance.<

SOCKET FOR ONBOARD DIAGNOSTICS OBD CARING FOR YOUR VEHICLEPrimary components of exhaust emissions
can be checked by a device via the OBD
socket.
This socket is located to the left of the
driver's side, on the bottom of the instru-
ment panel underneath a cover.Exhaust emission values
The warning lamp comes on. The
exhaust emissions have deterio-
rated. Have the vehicle checked as
soon as possible.
Canadian models display this
warning lamp.
Under some circumstances, the lamp will
flash. This indicates severe engine misfir-
ing. In this case, you should reduce your
speed and visit your nearest MINI Dealer as
soon as possible. Severe engine misfiring
can quickly lead to serious damage of emis-
sions-related components, especially the
catalytic converter.
If the fuel filler cap is not properly
tightened, the OBD system may con-
clude that fuel vapors are escaping, causing
an indicator to light up. If the filler cap is
then tightened, the indicator should go out
within a few days.<
Suitable car-care products
Use the cleaning and car-care prod-
ucts available at your MINI Dealer.<
Washing your vehicleYou can wash your new MINI or MINI Con-
vertible in automatic car washes from the
beginning. Preference should be for cloth
car washes. If, due to lack of availability,
brush car washes must be used, modern
systems with soft brushes should be given
preference.
When using steam cleaners or high-
pressure cleaners, maintain sufficient
distance to the vehicle and do not exceed a
maximum temperature of 1407/606. If
the jet is too close or the pressure is too
high, this can lead to damage or initial
damage that can develop into more serious
damage. Water that enters vehicle compo-
nents can lead to damage over the long
term.
After washing the vehicle, apply the brakes
briefly to dry them, otherwise water can
reduce braking efficiency over the short
term and the brake rotors can corrode.
Switch the rain sensor off when passing
through an automatic car wash, refer to
page63. Failure to do so could result in
