BREAK-IN PROCEDURES GENERAL DRIVING NOTESMoving parts need to be given some time
until they can interact smoothly with one
another. To ensure that your vehicle pro-
vides maximum economy throughout a
long service life, we request that you com-
ply with the following information:EngineComply with the local speed limits.
Up to 1,250 miles/2,000 km:
Drive at varying engine and road speeds,
but do not exceed the following:
4,500 rpm or
95 mph / 150 km/h.
Absolutely avoid putting the accelerator in
full-throttle or kickdown position.
After 1,250 miles/2,000 km:
Engine and road speeds can be gradually
increased.
TiresDue to technical factors associated with
their manufacture, tires do not achieve
their full traction potential until after an
initial break-in period. Therefore drive care-
fully during the first 200 miles/300 km.Brake systemApprox. 300 miles/500 km must be driven
before the brake pads and rotors achieve
the optimum pad-surface and wear pat-
terns required for trouble-free operation
and an extended service life.ClutchRoughly 300 miles/500 km must be driven
before the clutch starts to operate at opti-
mum efficiency. Remember to engage the
clutch carefully during this initial period.After a part replacementYou should again comply with these break-
in procedures if parts mentioned above
have to be replaced later in the vehicle's
life.
Interior mirror, automatic dimming*While the vehicle is being driven forward,
these mirrors dim light through an infi-
nitely variable range depending on the
light's incidence. Two photocells in the
interior rearview mirror serve this purpose.
One is positioned on the underside of the
mirror frame, while the other is slightly off-
set on the back of the mirror.
In order for the photocells to work opti-
mally, keep them clean and do not cover
the area between the interior rearview mir-
ror and the windshield. Do not place stick-
ers or toll tags on the windshield in front of
the mirror.

GENERAL DRIVING NOTESSafe braking Your vehicle is equipped with ABS as a stan-
dard feature. If you are in a situation which
requires full braking, it is best to brake
using maximum brake pressure. Since the
vehicle remains maneuverable, you can still
go around any obstacles with the smallest
possible steering movements.
The pulsation of the brake pedal, together
with the sound of hydraulic regulation,
indicates to you that ABS is actively taking
effect.
Wet roads:
It is a good idea to periodically dry the
brakes with a gentle application when driv-
ing in rain and on wet roads. Monitor traffic
conditions to ensure that this maneuver
does not hinder other road users. The
resulting heat dries brake rotors and pads.
Then if the braking force is needed, it is
immediately available.
Driving downhill:
To prevent overheating and the
resulting reduced efficiency of the
brake system, drive down extended or
steep mountain gradients in the gear
which requires the least brake applications.
Otherwise, even light but consistent pres-
sure on the brake can lead to high tempera-
tures, brake wear and possibly even brake
failure.<
The braking effect of the engine can be
increased by downshifting in the manual
mode of the automatic transmission, to
first gear if necessary, refer to page58. This
protects the brakes from excessive loads.
Do not coast with the clutch
depressed, the transmission in idle or
the engine switched off. Otherwise, the
engine provides no braking effect, and
there is no power-assist for braking or
steering.
Make sure that there are no floor mats,
floor carpets or other objects in the vicinity
of the pedals; otherwise pedal function
could be impeded.<
Corrosion on the brake rotors:
When the vehicle is driven only occasion-
ally, 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 ten-
dency for corrosion of the brake rotors and
accumulation of contamination on the
brake pads. This occurs because the mini-
mal pressure that must be exerted by the
pads to clean the rotors by brake applica-
tions is not reached.
Corrosion on brake rotors is signaled by a
running or pulsation during braking; even
extended subsequent braking will not cure
this phenomenon.Brake pads
Sensors in the left front and right
rear brake pads monitor pad condi-
tion. When the brake pads have
worn to the permissible limit, this is indi-
cated by the brake wear warning light,
refer to page18.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires
and road surface. This phenomenon is char-
acterized by a partial or complete loss of
contact between the tires and the road sur-
face. The ultimate results are loss of steer-
ing and braking control.<

TIRE INFLATION PRESSURE Information for your safetyIt is not merely the tire's service life, but
also driving safety and driving comfort that
depend on the condition of the tires and
the maintenance of the specified tire pres-
sure.Checking tire inflation pressuresCheck the tire inflation pressures only on
cold tires. This means after driving a maxi-
mum of 1.25 miles/2 km or when the vehi-
cle has been parked for at least 2 hours.
Warm tires have higher pressures.
Check the tire inflation pressures reg-
ularly and correct them, if necessary,
including the space-saver spare tire: at
least twice a month and before an
extended trip. Otherwise, incorrect tire
pressures can cause driving instability or
tire damage, ultimately resulting in acci-
dents. Do not drive with deflated, i.e. flat,
tires except if Run-Flat Tires are fitted. A
flat tire greatly impairs steering and brak-
ing response, and can lead to complete loss
of control over the vehicle.<
After correcting the tire inflation
pressure, reinitialize the Flat Tire
Monitor
*, refer to page74 or reset the Tire
Pressure Monitor
*, page 76.<
Tire inflation pressures for original
tiresThe tire inflation pressures for your stan-
dard tires are shown on the driver's-side
door post, visible when the door is open.Tire inflation pressures for other tire
sizesIn the following tire pressure table, all pres-
sures are given for the specified tire sizes at
ambient temperature.
In order to determine the correct
inflation pressures for your tires,
refer to the values for the tire size in ques-
tion.<
Checking the inflation pressure on the
space-saver spare tireBehind the bumper there is a valve exten-
sion accessible from the outside for check-
ing the inflation pressure.Tire sizeThe tire inflation pressures apply to the tire
sizes approved and the tire brands recom-
mended by the manufacturer of your MINI.
Your MINI Dealer will be glad to advise you.

Tire age
Tire ageThe tire's date of manufacture is included
in the tire coding:
DOT...3506 means that the tire was manu-
factured in the 35th week of the year 2006.
The manufacturer of your MINI recom-
mends replacing all tires after 6 years at
the latest, even if a tire service life of
10 years is possible.Uniform Tire Quality GradingQuality grades can be found where applica-
ble on the tire sidewall between tread
shoulder and maximum section width.
For example:
Treadwear 200 Traction AA
Temperature A
DOT quality gradesTread 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. ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government 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,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.

OVERVIEW REPAIRSOPERATIONCONTROLS DATA INDEX
TIRE CODING TIRE CONDITION Traction The traction grades, from highest to low-
est, 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 govern-
ment test surfaces of asphalt and concrete.
A tire marked C may have poor traction per-
formance.
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics. B and C, representing the tire's resistance
to the generation of heat and its ability to
dissipate heat when tested under con-
trolled conditions on a specified indoor lab-
oratory test wheel.
Sustained 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 meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the labora-
tory test wheel than 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 combination, can
cause heat buildup and possible tire fail-
ure. lar symbol containing the letters RSC on
the side of the tire, refer to page115.M+SWinter and all-season tires.
These have better winter performance
properties than summer tires.
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.Tire treadTread depth should not be allowed to go
below 1/8 in/3 mm even though in Europe,
for example, the legally specified minimum
tread depth is only 1/16 in/1.6 mm.
Below 1/8 in/3 mm tread depth, there is a
very high danger of hydroplaning at higher
speeds, even with only small amounts of
water on the road.
At tread depths below approx. 1/6 in/
4 mm, the ability of winter tires to cope
with winter driving conditions decreases
perceptibly. For safety reasons, new tires
should be mounted.
