166Vehicle careWhen the engine oil level has
dropped to the MIN mark, top-up
engine oil.Caution
Do not allow the engine oil level to drop below the minimum level!
We recommend the use of the same
grade of engine oil that was used at
the last change.
The engine oil level must not exceed the maximum mark MAX on the
dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
To prevent spillage when
replenishing the engine oil, we
recommend using a funnel to top-up the engine oil. Ensure funnel is
securely located onto the filler pipe.
After topping-up, put the funnel into a
plastic bag and stow it securely.
A stabilization of the engine oil
consumption will not take place until the vehicle has been driven several
thousand miles. Only then can the
actual degree of consumption be
established.
If consumption exceeds more than
0.6 litres every 600 miles after this
running-in period, consult a
workshop.
Capacities 3 216.
Fit the cap on straight and tighten it.
Engine air filter
Engine air flow indicator
On certain models, an indicator is
located in the engine induction
system and indicates if the air-intake
to the engine is restricted.
Clear:No restrictionRed tell-tale:Restricted
If the red tell-tale is displayed when
the engine is running, consult a
workshop.

Vehicle care167Engine coolant
The coolant provides freeze
protection down to approx. -28 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine 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.
If the coolant temperature is too high, control indicator W 3 97 illuminates
red in the instrument cluster, together
with C 3 96. Consult a workshop if
coolant level is sufficient.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap or from
entering the reservoir.
The power steering fluid reservoir is located below the front left wheel
arch, behind a trim panel.
The fluid level normally does not need
to be checked. If an unusual noise is
heard during steering or if the power
steering reacts conspicuously, seek
the assistance of a workshop.
Page 171 of 233

Vehicle care169The brake fluid level must be between
the MINI and MAXI marks.
When topping up, ensure maximum
cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Only use high-performance brake
fluid approved for your vehicle.
Brake fluid 3 202.
Vehicle battery
The vehicle battery is located under a cover in the engine compartment.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Control indicator p illuminates if
there is a fault with the charging
system. Stop, switch off engine and
seek the assistance of a workshop.
Charging system 3 96.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge.
9 Danger
Ensure the ignition is switched off
completely (the vehicle must not
be in an Autostop) before
connecting or disconnecting the
vehicle battery.
Stop-start system 3 134.
Replacing the vehicle battery
Ensure that the battery is alwaysreplaced by the same type of battery.
Seek the assistance of a workshop to
have the vehicle battery replaced.
Stop-start system 3 134.
Charging the vehicle battery
9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may be damaged.

170Vehicle care9Danger
Ensure adequate ventilation when
charging the battery. There is a
risk of explosion if gases
generated during charging are
allowed to accumulate!
Jump starting 3 195.
Warning label
Meaning of symbols: ● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulfuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the battery.Additional battery
Depending on the vehicle's auxiliary
equipment, certain models may have
an additional battery mounted under
the front passenger bench seat.
Notice
The additional battery is
automatically connected to the main vehicle battery only when the engine
is running. It does not need to be
manually disconnected before

battery or before jump starting the vehicle.
The terminals are designed for
additional electrical consumers up to
a maximum of 50 A.

Diesel fuel filter The diesel fuel filter is accessible from the underside of the vehicle.
Drain filter of residual water at every
engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screw on the lower part of the filter by approx. one turn, to drain off the
water.
The filter is drained as soon as water-
free diesel fuel emerges. Retighten
the screw.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.

Vehicle care179Electrical system
Fuses Data on the replacement fuse must
match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● on the left-hand side of the instrument panel, behind the trim
panel
● in the engine compartment located next to the battery
Notice
The engine compartment fuse box
should only be accessed by a
workshop.
Before replacing a fuse, turn off the
respective switch and the ignition.
There are different types of fuses in
the vehicle.
Depending on the type of fuse, a
blown fuse can be recognised by its
melted wire. Do not replace the fuse until the cause of the fault has been
remedied.
It is advisable to carry a full set of
fuses. Provision is made in the fuse
box for the storing of spare fuses.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.
Notice
Not all fuse box descriptions in this
Owner's Manual may apply to your
vehicle. Refer to the fuse box label,
where fitted.
