Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. Equipment is also described
that is not available because of, for example,
selected options or coun try version. This also
applies to safety relate d functions and systems.
Tire inflation pressures
Information for your safety
It is not merely the tire s' 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 73,
or reset the Tire Pressure Monitor, page 76.<
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 sizes for your vehicle
> Maximum allowable driving speed
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
pressures listed on the following pages in the
columns for traveling sp eeds 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 identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.

Speed letter
Q = up to 100 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h

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 C
All 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 course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart si gnificantly 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 con-
trolled conditions on specified government test
surfaces 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 include acceleration,
cornering, hydroplaning, or peak traction
characteristics. <
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 corresponds 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 overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combin ation, can cause heat
buildup and possible tire failure. <
RSC - run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side of
the tire, page 203.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Designation for specia lly reinforced tires.
Tire condition
Inspect your tires regula rly for tread wear, signs
of damage and for foreign objects lodged in the
tread. Check the tread depth.
Tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for exam ple, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
Winter tires
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less suitable for winter condit
ions. In the interest of
safety, new tires should be installed.
Minimum tread depth
Wear indicators in the base of the tread groove
are distributed around th e tire's circumference;
the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. If the tire tread has been
driven down to the wear indicators, a tread
depth of 0.063 in/1.6 mm has been reached.
Tire damage
Driving over rough or damaged road surfaces, as
well as debris, curbs, and other obstacles can
cause serious damage to wheels, tires, and
suspension parts. This is more likely to occur
with low-profile tire s, which provide less
cushioning between the wheel and the road.
Be careful to avoid road hazards and reduce
your speed, especially if your vehicle is equipped
with low-profile tires.
Unusual vibrations encountered during normal
vehicle operation can indi cate tire failure or
some other vehicle defect . This can, for exam-
ple, be caused by drivin g over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immediately
and have wheels and tires thoroughly
checked. To do so, drive carefully to the nearest
MINI dealer or a specialized tire shop that has
specially trained personnel working in accor-
dance with the specifications of the MINI manu-
facturer. If necessary, have the vehicle towed
there.

Otherwise, tire damage can be extremely dan-
gerous for vehicle occupants and other road
users.<
Tire age
The manufacturing date of tires is contained in
the tire coding:
DOT ... 1012 means that the tire was manufac-
tured during the 10th week of 2012.
For various reasons, such as the development of
brittleness, the manufacturer of your MINI rec-
ommends tire replacemen t after no more than
6 years, regardless of th e actual wear of the
tires.
Run-flat tires
The symbol identifying run- flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires comprise a conditionally self-sup-
porting tire and a special rim. The reinforcement
in the sidewalls ensures that the tire can con-
tinue to be used subject to certain restrictions,
even if depressurized.
For information on continuing to drive with a flat
tire, refer to Indication of a flat tire, page74.
New wheels and tires
Have new wheels and tires mounted only
by your MINI dealer or a specialized tire
shop that has specially trained personnel
working in accordance with the specifications of
the MINI manufacturer. If this work is not carried out properly, there is a danger of subsequent
damage and related safety hazards. Make sure
that the new wheels are balanced.
<
Retreaded tires
The manufacturer of your MINI recom-
mends that you avoid using retreaded
tires, as this could impair driving safety. The
causes for this include potentially different tire
casing structures and of ten wide variations in
tire age, which can result in a limited service
life.<
Correct wheels and tires
The manufacturer of your MINI recom-
mends mounting only wheels and tires
that it has specifically approved for use on your
particular model. Alth ough other wheels and
tires may theoretically have the same dimen-
sions, variations in factors such as manufactur-
ing tolerances can result in contact between tire
and bodywork, ultimately leading to serious
accidents. The manufactur er of your MINI can-
not evaluate non-approved wheels and tires to
determine if they are su ited for use, and there-
fore cannot ensure the operating safety of the
vehicle if they are mounted. <
Your MINI dealer will be glad to inform you
about the correct wheel an d tire combination for
your vehicle.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS and DSC.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. After a tire has been
damaged, mount the previous wheel and tire
combination again as soon as possible.

puncture, refer to page76. Your MINI dealer will
be glad to advise you.
Recommended tire brands
For each tire size, the manufacturer of your MINI
recommends certain tire brands. They are
marked with a clearly vi sible MINI designation
on the sidewall of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Run-flat tires
When mounting new tires or changing over from
summer to winter tires and vice versa, mount
run-flat tires for your ow n safety. Keep in mind
that no space-saver spare tire is available in the
event of a flat. Your MINI dealer will be glad to
advise you.
Special characteristics of winter tires
The manufacturer of your MINI recommends the
use of winter tires on snowy roads or if temper-
atures drop below 45 7/ +7 6. Although all-
season M+S tires provide better winter traction
than summer tires, they generally fail to provide
the same levels of cold-weather performance as
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents. < If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in
your field of view. This
label is available at your tire dealer or MINI
dealer.
Storage
Always store wheels and tires in a cool, dry place
with as little exposure to light as possible.
Always protect tires agains t all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres-
sure indicated on the side wall of the tire.
Swapping wheels among the axles
Depending on the individual use, front and rear
tires may exhibit different wear and tear.
In order to maintain an even wear and tear, the
wheels may be rotated between the axles. Your
MINI dealer will be glad to advise you.
Always check the inflation pressure after the tire
rotation, if necessary change the pressure.
Snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your MINI,
classified as road-safe and recommended. Con-
tact your MINI dealer for more details.
Only attach snow chains in pairs to the front
wheels with the following tires.
>195/60 R 16 M+S
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph or 50 km/h. Do not initialize the Flat Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow ch ains, it can be useful
to briefly deactivate DSC or activate DTC, refer to
page 71.<

CareMOBILITY
213
Preservation
Preservation is necessary when water no longer
beads on the clean paint surface. To preserve
the paint, only use preservatives that contain
carnauba or synthetic waxes.
Rubber seals
Only treat with water or rubber care products.Do not use silicon sprays or other silicon-
containing care products on rubber seals;
otherwise, noise and damage could occur. <
Chrome parts
Carefully clean vehicle parts such as the radiator
grill and door handles with copious quantities of
water and, if necessary, a shampoo additive,
especially when contaminated with road salt.
For additional treatment, use chrome polish.
Light alloy wheels
The system produces brake dust that collects on
the light alloy wheels. Clean them regularly with
acid-free wheel cleaner.
Do not use aggressive , acid-containing,
highly alkaline, or abrasive cleansers or
steam jets hotter than 140 7/60 6 as they may
cause damage. <
External sensors
Keep the outside sensors on the vehicle
such as the Park Di stance Control clean
and ice-free to ensure that they function
properly. <
Internal care
Upholstery/fabrics
Regularly use a vacuum cleaner to remove
surface dirt.
In case of serious spots such as liquid stains, use
a soft sponge or lint-f ree microfiber cloth and
suitable interior cleaners. Observe the instruc-
tions on the packaging. Clean upholstery up to the seams. Do not
rub forcefully.
<
Velcro fasteners on pants or other items of
clothing can damage seat covers. Make
sure that all Velcro fasteners are closed. <
Leather/leather coverings
The leather processed by the manufac-
turer of your MINI is a high-quality natural
product. Light variations in the grain is one of
the typical properties of natural leather. <
Dust and road grit in the pores and folds of the
leather have an abrasive effect, leading to
increased wear and causing the leather surface
to become brittle prematurely. Use a cloth or
vacuum cleaner to remove dust on a regular
basis.
Especially when the leather has a light color, it
should be cleaned regularl y since it tends to get
heavily soiled.
Treat the leather twice a year using a leather
lotion since dirt and grease will gradually attack
the leather's protective layer.
Carpets/floor mats
Keep floor mats, carp et, and other objects
out of the movement range of the pedals;
otherwise, they may inhi bit the function of the
pedals during driving.
Do not place additional floor mats onto an
existing one or onto other objects.
Only use floor mats that have been approved for
the vehicle and can be appropriately fastened.
Make sure that the fl oor mats are securely
fastened again after they have been removed,
e.g. for cleaning. <
Floor mats can be removed to be cleaned.
If the carpets are very dirty, clean with a micro-
fiber cloth and water or an interior cleaner.
When doing so, rub forward and back in the
driving direction; othe rwise, the carpet may
become matted.
