Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the vehi-
cle placard or tire inflation pressure label, you
should determine the proper tire inflation pres-
sure for those tires. As an added safety feature,
your vehicle has been equipped with a tire pres-
sure monitoring system TPMS that illuminates a
low tire pressure telltale when one or more of
your tires are significantly underinflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat
and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if underinflation has not reached
the level at which the TPMS low tire pressure tell-
tale illuminates.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue
upon subsequent vehicle startups as long as the
malfunction exists. When the malfunction indi-
cator is illuminated, the system may not be able
to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction telltale
after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.

Cupholders and ashtray*
Cupholders
Two cupholders are located in the front of the
center console; another is in the rear at the back
of the center console.
Do not place glass containers in the cup-
holders, as this increases the risk of injury
in the event of an accident.<
Ashtray*
The ashtray is located in one of the cupholders in
the center console.
Emptying
Remove the entire ashtray.
Lighter
With the engine running or the ignition switched
on, press in the cigarette lighter.
The lighter can be pulled out as soon as it pops
back out.
Hold or touch the hot cigarette lighter by
the knob only. Holding or touching it in
other areas could result in burns.
When leaving the car, always remove the key so
that children cannot operate the cigarette
lighter and burn themselves.<
Connecting electrical
appliances
In your MINI, you can use electrical devices such
as a flashlight, car vacuum cleaner, etc., up to
approx. 200 watts at 12 volts, as long as one of
the following sockets is available. Avoid damag-
ing the sockets by attempting to insert plugs of
unsuitable shape or size.
Cigarette lighter socket
Remove the lighter* or cover from the socket.

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 pres-
sure.
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 precaution you may be driving
on tires with incorrect tire pressures, a condition
that can not only compromise your vehicle's
driving stability, but also lead to tire damage and
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.
Attempts to drive on a flat tire can lead to loss 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 hours. When tires are warm,
the tire inflation pressure is higher.
After adjusting the tire inflation pressure,
reinitialize the flat tire monitor, page66,
or reset the Tire Pressure Monitor, page68.<
Checking the tire inflation pressure of
the space-saver spare tire*
A valve extension for checking the inflation pres-
sure 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 identification of the right tire infla-
tion pressures, observe the following:
>Tire sizes for your vehicle
>Load conditions
>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 pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's side door post when the driver's
door is open.

Tire coding
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 100 mph or 160 km/h
T = up to 118 mph or 190 km/h
H = up to 131 mph or 210 km/h
V = up to 150 mph or 240 km/h
W = up to 167 mph or 270 km/h
Y = up to 186 mph or 300 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 (1γ) 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 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 include acceleration, corner-
ing, hydroplaning, or peak 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 laboratory 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 passenger car tires must e.g.
