Vehicle care273Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can causeengine damage.
If the cooling system is cold, the
coolant level should be just above the
MINI mark. Top up if the level is low.
9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
Top up with antifreeze. If no
antifreeze is available, use clean tap
water or distilled water. Install the cap
tightly. Have the antifreeze
concentration checked and have the
cause of the coolant loss remedied by a workshop.
If a substantial amount of coolant is
required, it will be necessary to bleed
any trapped air from the cooling
system. Seek the assistance of a
workshop.
Power steering fluid If an unusual noise is heard during
steering or if the power steering
reacts conspicuously, seek the
assistance of a workshop.
The power steering fluid reservoir is
located below the front left wheel
arch, behind a trim panel. Access is
only possible for a workshop.
Washer fluid

292Vehicle careThe tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
highest pressure specified for this
tyre size.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the type of drive.
2. Identify the gross vehicle weight.
3. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 317.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the
tyre information label and tyre
pressure chart are valid for cold tyres, which means at 20 °C. The pressure
increases by nearly 10 kPa (0.1 bar)
for a 10 °C temperature increase.
This must be considered when warm
tyres are checked.
Trailer towing
When towing a trailer with a fully laden vehicle, the tyre pressure must
be increased by 20 kPa / 0.2 bar
(3.0 psi) and the maximum speed
limited to 100 km/h.
Trailer towing 3 265.
Rear-wheel drive, with twin rear
wheels
When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.

During driving, select the tyre
pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. five seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving at a speed above 40 km/h may be required to
complete the relearn process. The system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.
Driver Information Centre 3 105.
Vehicle messages 3 106.General information
The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.
Tyre repair kit 3 296.
Tyre chains 3 295.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors must be dismounted and
serviced by a workshop.
Tread depth Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2–3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
Page 297 of 353

Vehicle care295
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those fitted at the factory are used, it may be necessary to reprogramme the
nominal tyre pressure and make
other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.
Tyre pressure monitoring system
3 292.9 Warning
The use of unsuitable tyres or
wheels may lead to accidents and will invalidate the vehicle
operating permit.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
drive wheels.
