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.

OVERVIEW REPAIRSOPERATIONCONTROLS DATA INDEX
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.<

SOCKET FOR ONBOARD DIAGNOSTICS OBD CARING FOR YOUR VEHICLEPrimary components of exhaust emissions
can be checked by a device via the OBD
socket.
This socket is located to the left of the
driver's side, on the bottom of the instru-
ment panel underneath a cover.Exhaust emission values
The warning lamp comes on. The
exhaust emissions have deterio-
rated. Have the vehicle checked as
soon as possible.
Canadian models display this
warning lamp.
Under some circumstances, the lamp will
flash. This indicates severe engine misfir-
ing. In this case, you should reduce your
speed and visit your nearest MINI Dealer as
soon as possible. Severe engine misfiring
can quickly lead to serious damage of emis-
sions-related components, especially the
catalytic converter.
If the fuel filler cap is not properly
tightened, the OBD system may con-
clude that fuel vapors are escaping, causing
an indicator to light up. If the filler cap is
then tightened, the indicator should go out
within a few days.<
Suitable car-care products
Use the cleaning and car-care prod-
ucts available at your MINI Dealer.<
Washing your vehicleYou can wash your new MINI or MINI Con-
vertible in automatic car washes from the
beginning. Preference should be for cloth
car washes. If, due to lack of availability,
brush car washes must be used, modern
systems with soft brushes should be given
preference.
When using steam cleaners or high-
pressure cleaners, maintain sufficient
distance to the vehicle and do not exceed a
maximum temperature of 1407/606. If
the jet is too close or the pressure is too
high, this can lead to damage or initial
damage that can develop into more serious
damage. Water that enters vehicle compo-
nents can lead to damage over the long
term.
After washing the vehicle, apply the brakes
briefly to dry them, otherwise water can
reduce braking efficiency over the short
term and the brake rotors can corrode.
Switch the rain sensor off when passing
through an automatic car wash, refer to
page63. Failure to do so could result in
