WHEEL AND TIRE COMBINATIONS WINTER TIRESThe right choiceThe factory-approved normal and Run Flat
tires are matched to your vehicle and have
been selected to provide optimum safety
and driving comfort if used properly.
The manufacturer of your MINI rec-
ommends never mounting wheels
and tires that have not been specifically
approved by the manufacturer for use on
your particular model. Although other
wheels and tires may theoretically have the
same dimensions, variations in factors such
as manufacturing tolerances can result in
contact between tire and bodywork, ulti-
mately leading to serious accidents. The
manufacturer of your MINI cannot evaluate
non-approved wheels and tires to deter-
mine if they are suited for use, and there-
fore cannot ensure the operating safety of
the vehicle if they are fitted.<
The manufacturer of your MINI has tested
certain tire brands in each size, categorized
them as safe for use on the road, and
approved them. Contact your MINI Dealer
for more details.
The correct wheel and tire combina-
tion affects various systems that
would otherwise be impaired, e.g. ABS,
ASC+T and DSC. For this reason, use only
tires of the same manufacture and tread
configuration. In the event of a flat tire, for
example, remount the approved wheel and
tire combination as soon as possible.<
StorageStore tires in a cool, dry place, protecting
them against light whenever possible.
Protect the tires against contact with oil,
grease and fuel.
Choosing the right tireThe manufacturer of your MINI recom-
mends winter tires – M+S radial tires – for
driving in adverse winter road conditions.
While so-called all-season tires with M+S
designation provide better winter traction
than summer tires with the load ratings S,
T, H, V, W, they do not achieve the perfor-
mance of winter tires.
In the interest of safe tracking and steering
response, install winter tires made by the
same manufacturer having the same tread
configuration on all four wheels.
Before purchasing winter tires, check
whether your MINI is fitted with Run Flat
tires. You will recognize Run Flat tires by a
circular symbol containing the letters RSC
on the side of the tire, see page 116. In this
case, use only Run Flat tires, as in the event
of a flat tire there is no space-saver spare
tire.
Any MINI Dealer will be glad to advise you
on the selection of the right winter tires for
the relevant operating conditions.

WINTER TIRES SNOW CHAINS
*
Observing speeds
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and accidents.
Have this work performed by skilled profes-
sionals only. Your MINI Dealer will be glad
to assist you with both their expertise and
the proper equipment for your vehicle.<
Tire condition, tire inflation pressure
Below a tread depth of
3/16 in /
4 mm, winter tires display a percepti-
ble decrease in their ability to cope with
winter driving conditions, and should be
replaced in the interest of safety.<
Comply with the specified tire inflation
pressures and be sure to have the wheel
and tire assemblies balanced every time
you change the tires.
Only certain types of snow chains have
been tested by the manufacturer of your
MINI, classified as road-safe and approved.
Contact your MINI Dealer for more details.
The manufacturer of your MINI recom-
mends that you use these fine-link snow
chains only. Their use is only permitted in
pairs on the front wheels on winter tires of
the following type:
175/65 R 15.
When fitting, comply with the manufac-
turer's instructions. With chains, do not
exceed a speed of 30 mph / 50 km/h.
After fitting the snow chains, do not
activate the Flat Tire Monitor.
When driving with snow chains, it can be
helpful to switch off the ASC+T or DSC for a
brief period, see pages 62, 63.<

BONNET
Do not attempt to service your vehi-
cle if you do not have the required
technical background. Before working in
the engine compartment, switch off the
engine and allow it to cool down. Before
working on the electrical system, always
disconnect the battery first. For all work on
the vehicle, comply with the appropriate
information and instructions. Failure to
work in an informed, professional manner
when servicing components and materials
constitutes a safety hazard for vehicle
occupants and other road users. If you are
not familiar with the guidelines, please
have the operations performed by your
MINI Dealer.<
To unlock Pull the lever in the right door area beneath
the instrument panel.
To open1. Reach under the bonnet
2. Pull the release lever
3. Open the bonnet.To closeAllow the bonnet to fall from a height of
approx. 1 ft / 30 cm.
To avoid injuries, be sure that the
travel path of the bonnet is clear
when it is closed, as with all closing proce-
dures.
If it is determined that the bonnet is not
completely closed while driving, stop
immediately and close it securely, see also
page 16.<

WASHER FLUID ENGINE OILHeadlamp* and windshield washer
systemsThe capacity of the headlamp washer sys-
tem is approx. 2.6 quarts / 2.5 liters, that of
the windshield washer system approx.
2.1 quarts / 2.0 liters.
Fill with water and – if required – with anti-
freeze, according to manufacturer's recom-
mendations.
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Antifreeze agent for the washer sys-
tems is flammable. Always keep it
well away from sparks and open flames,
and store it in tightly closed containers well
out of the reach of children. Always observe
the instructions for use provided on the
container.<
The illustration shows as an example the
dipstick of the MINI COOPER.Measuring the oil level 1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating temperature
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 must 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.

ENGINE OILThe oil volume between the two notches –
MIN, MAX – on the dipstick corresponds to
approx. 1.1 quarts / 1 liter. Do not fill
beyond the upper notch on the dipstick.
Excess oil will damage the engine.
Adding engine oil
Only top up oil when the oil level has
dropped to just above the lower
notch of the dipstick. However, never allow
the level to drop below the lower notch.<
MINI engines are designed to operate
without oil additives; the use of addi-
tives could lead to damage in some cases.
That is also valid for the Continuously Vari-
able automatic Transmission (CVT), the
gear box and the power assisted steering.<
The manufacturer of your MINI recom-
mends that you have the oil changed at
your MINI Dealer.
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come
into contact with oil should be thoroughly
washed with soap and water.
Always store oil, grease, etc., out of reach of
children. Comply with all warning labels
and information on lubricant containers.<
Comply with the applicable environ-
mental laws regulating the disposal
of used oil.<
Specified engine oilsThe quality of the engine oil selected has
critical significance for the operation and
service life of an engine. Based on extensive
testing, the manufacturer of your MINI
approves only certain grades of engine oil.
Use only approved MINI High Performance
Synthetic Oil.
If you are unable to obtain MINI High Per-
formance Synthetic Oil, you can add small
amounts of synthetic oil in between oil
changes. Only use oils with the API SH spec-
ification or higher.

ENGINE OIL COOLANT
Ask your authorized MINI Dealer for
details concerning the specific MINI
High Performance Synthetic Oil or syn-
thetic oils which have been approved.<
ViscositiesViscosity is the oilflow rating as established
in SAE classes.
The choice of the proper SAE class depends
on the climatic conditions in the area
where your MINI is used.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils can be used at all ambient tem-
peratures.
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.
Antifreeze and anti-corrosion agents are
hazardous to health. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.
Antifreeze and anti-corrosion agents are
flammable. Therefore, do not spill them
over hot engine parts; otherwise they may
ignite and cause burns. Always observe the
instructions for use provided on the con-
tainers.<
Comply with the applicable environ-
mental laws regulating the disposal
of antifreeze and anti-corrosion agents.<
The illustration shows as an example the
coolant tank on the MINI COOPER.Checking coolant levelCorrect coolant level with cold engine –
approx. 68 7 / 20 6:
Up to the MAX mark of the transparent
expansion tank.
Only open the cap of the expansion
tank when the engine has cooled
down. The needle on the coolant tempera-
ture gauge in the instrument cluster must
be no higher than in the first quarter, oth-
erwise there is a danger of scalding.<

COOLANT BRAKE FLUIDTo add coolant
MINI COOPER:
1. Slowly open the cap by pulling at the tab
to allow accumulated pressure to
escape.
2. Pull open the cap completely.
3. If the coolant is low, slowly add coolant
until the correct level is reached – do not
overfill.
MINI COOPER S:
1. Open the cap by turning it slightly coun-
terclockwise to allow accumulated pres-
sure to escape.
2. Unscrew and open the cap completely.
3. If the coolant is low, slowly add coolant
until the correct level is reached – do not
overfill.
The coolant is made up of water and an
antifreeze with corrosion resistance. The
mixture ratio of 50 to 50 must be kept the
entire year due to the required anti-corro-
sion property. No other additives are
required.
Replace the coolant every three years.
Warning lamp
If the brake warning lamp comes
on with the parking brake released:
The brake fluid level is too low, see
page 15.
Brake warning lamp for Canadian
models.
Adding brake fluidTo add brake fluid or to determine and cor-
rect the cause of brake fluid loss, consult
your MINI Dealer. Your MINI Dealer is famil-
iar with the specifications for factory-
approved brake fluids – DOT 4.
Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer to
the information on page 84.
Brake fluid is hygroscopic, that is, it
absorbs moisture from the air over
time.
In order to ensure the brake system's safety
and reliability, have the brake fluid
changed every two years by a MINI Dealer,
see also the Service and Warranty Informa-
tion Booklet for US models or the Warranty
and Service Guide Booklet for Canadian
models. Brake fluid is toxic and also dam-
ages vehicle paintwork. Always store brake
fluid in tightly-closed original containers
kept well away from the reach of children.
Do not spill the brake fluid and do not fill
the brake fluid reservoir beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and cause
serious burns.<
Comply with the applicable environ-
mental laws regulating the disposal
of brake fluid.<

MINI MAINTENANCE SYSTEMThe MINI Maintenance System has been
designed as a reliable means of providing
maximum driving and operating safety –
and as cost-effective for you as possible.
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 specify main-
tenance according to fixed distances
driven, the MINI Maintenance System takes
account of the operating conditions of the
vehicle, for distances can be driven in many
different ways:
60,000 miles / 100,000 km short distance
operation can not be equated with
60,000 miles / 100,000 km long distance
operation from a maintenance standpoint.
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 – 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, see page 60.
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.
Have your vehicle's maintenance and
repairs performed at your MINI
Dealer. Be sure that all maintenance work
is confirmed 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. They are also a requirement
for warranty claims.<
