DRIVING TIPSThings to remember when driving

Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic climate
control is in operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are therefore normal.
In the MINI Cooper S, the coolant pump may
continue to run for some time after the engine is
switched off. This will generate noise in the
engine compartment.
Cargo loading
To avoid loading the tires beyond their
approved carrying ca pacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result can
assume the form of a sudden blowout. <
Avoid fluid spills in the cargo area as they
could damage the vehicle. <

Do not place any objects on the cover;

occupants, e.g. in the case of braking or sudden
swerving, or they may damage the cover. is raised.
To load bulky luggage, the cover can be
removed.
1.
Unhook the lift straps from the liftgate.
2. Pull the cover out of the holders toward the
rear.
Expanding the cargo area
The rear set backrest is split. Both sides can be
folded separately to expand the cargo area.
1. Pull the lever.
2. Fold rear seat backrests forward.
When folding the backrest back up, make
sure that the seat's locking mechanisms
engage properly. Otherwise, cargo could be
thrown around in the event of sharp braking or
swerving and endanger the occupants.<

Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire
pressure.
Checking pressure
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precauti on you may be driving
on tires with incorrect ti re pressures, a condition
that can not only compromise your vehicle's
driving stability, but also l e a d t o t i r e d a m a g e a n d
the risk of an accident. Do not drive with
deflated, i.e. flat tires, except when using run-
flat tires. A flat tire will seriously impair your
vehicle's handling and braking response.
Att empt s to drive o n a flat t ire can lead to lo ss of
control over the vehicle. <
Check the tire inflation pressures only on cold
tires. This means after a maximum of 1.25 miles/
2 km driving or when the vehicle has been
parked for at least 2 hou rs. When tires are warm,
the tire inflation pressure is higher.
After adjusting the tire inflation pressure,
reinitialize the flat tire monitor, page 70,
or reset the Tire Pressure Monitor, page 72.<

A valve extension for checking the inflation
pressure is located behind the bumper.
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The tire inflation pressures apply to the
tire sizes approved and the tire brands
recommended by the manufacturer of your
MINI. Your MINI dealer will be glad to advise
you. <
For correct identificati on of the right tire
inflation pressures, observe the following:

Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation values
listed on the following pages in the columns for
traveling speeds up to a maximum of 100 mph
or 160 km/h.
These tire inflation pre ssures can also be found
on the driver's side door pillar when the driver's
door is open.
The maximum permitted speed for these
tire inflation pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents may occur. <
Tire inflation pressures for driving above
100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100mph or 160km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the foll owing pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise,
tire damage and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the law could
occur.

Tire Identification Number
Tires with DOT codes meet the guidelines of the
US Department of Transportation.
DOT code:
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B CAll passenger car tires must conform to
Federal Safety Requirements in addition
to these grades. <
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 γ) times as
well on the government co urse as a tire graded
100. The relative performance of tires depends
upon the actual conditio ns of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire’s ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not incl ude acceleration, corner-
ing, hydroplaning, or pe ak traction characteris-
tics. <
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor labo ratory test wheel. Sus-
tained high temperature can cause the material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corre sponds to a level of
performance which all pa ssenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent lev-
els of performance on the laboratory test wheel
that exceed the minimum required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overlo aded. Excessive speed,
underinflation, or excessive loading, either
separately or in combin ation, can cause heat
buildup and possible tire failure. <

You will recognize run-flat tires by a circular
