4.3
Reading the oil levelThe oil level should be read with the ve-
hicle on level ground, after the engine
has been switched off for some time.
The dipstick must be used to read
the exact oil level and ensure that
the maximum level is not exceeded
(risk of engine damage). Refer to the
following pages.
It is normal for an engine to use oil for
lubrication and cooling of moving parts
and it is normal to top up the level be-
tween oil changes.
However, contact your approved
Dealer if more than 0.5 litres is being
consumed every 600 miles (1,000 km)
after the running in period.
Oil change frequency: check the oil
level from time to time and certainly
before any long journey to avoid the
risk of damaging your engine.
ENGINE OIL LEVEL: general information

C
In order to prevent splashback, it is
recommended that a funnel be used
when topping up/filling with oil.
– Remove the dipstick and wipe with a
clean, lint-free cloth;
– push the dipstick in as far as it will go (for vehicles equipped with a cap-
type dipstick C, screw the cap in as
far as it will go);
– take out the dipstick again;
– read the level: it should never go below the “min” A or above the
“max” B.
Once the operation has been com-
pleted, ensure that the dipstick is
pushed in as far as it will go or that
the “cap-type dipstick” is completely
screwed in.
Deactivate the Stop and
Start function for any opera-
tion performed in the engine
compartment.
Consult your approved Dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Exceeding the maximum
engine oil level
Under no circumstances
must the maximum fill
level B be exceeded: risk of damage
to the engine and catalytic conver-
ter.
If the oil level exceeds the maximum
level, do not start your vehicle and
contact an approved Dealer.

ENGINE OIL LEVEL: topping up, filling (2/2)OIL CHANGE
Never run the engine in an
enclosed space as exhaust
gases are poisonous.
Engine oil change: if you
are changing the oil when
the engine is hot, be careful
not to scald yourself if the
oil overflows.
Filling: take care when
topping up the oil that
no oil drips onto engine
components - risk of fire.
Remember to refit the cap securely
as there is a risk of fire if oil splashes
onto hot engine components.
The engine may be hot
when carrying out opera-
tions in close proximity. In
addition, the engine cooling
fan can come on at any moment.
Risk of injury.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
Deactivate the Stop and
Start function for any opera-
tion performed in the engine
compartment.
Oil changeService interval: refer to the
Maintenance Service Booklet for your
vehicle.
Oil change capacity
Please refer to the maintenance docu-
ment for your vehicle, or contact an au-
thorised dealer.
Always check the engine oil level using
the dipstick, as explained previously (it
should never fall below the minimum
level, or be over the maximum level on
the dipstick).
Engine oil gradeRefer to the Maintenance Service
Booklet for your vehicle.

4.8
Frequency of checking coolant level
Check the coolant level regularly
(very severe damage is likely to be
caused to the engine if it runs out of
coolant).
If the level needs to be topped up, only
use products approved by our Technical
Department which ensure:
– protection against freezing;
– an anti-corrosion protection for the cooling system.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Replacement interval
Refer to the Maintenance Document for
your vehicle.
Coolant level
With the engine switched off and on
level ground, the level when cold must
be between the MINI and MAXI marks
on reservoir 1.
Top this level up when cold before it
reaches the MINI mark.

Level 2
It is normal for the level to drop as the
brake shoes become worn, but it must
never drop lower than the “MINI" warn-
ing line.
If you wish to check the disc and drum
wear yourself, you should obtain the
document explaining the checking pro-
cedure from the manufacturer’s net-
work or web site.
Topping up
After any operation on the hydraulic cir-
cuit, a specialist must replace the brake
fluid.
Only use fluids approved by our
Technical Department (and taken from
a sealed container).
Replacement interval
Refer to the Maintenance Document for
your vehicle.
Brake fluid level
The level should be read with the engine
switched off and on level ground.
This should be checked frequently,
and immediately if you notice even the
slightest loss in braking efficiency.

BATTERY: breakdown recovery (1/2)
To avoid all risk of sparks:
– Ensure that any electrical consumers (courtesy lights, etc.) are switched
off before disconnecting or recon-
necting the battery.
– When charging, stop the charger before connecting or disconnecting
the battery.
– Do not place metal objects on the battery to avoid creating a short cir-
cuit between the terminals.
– Always wait at least one minute after the engine has been switched off
before disconnecting a battery.
– Make sure that you reconnect the battery terminals after refitting.
Connecting a battery charger
The battery charger must be com-
patible with a battery with nominal
voltage of 12 volts.
Do not disconnect the battery while the
engine is running. Follow the instruc-
tions given by the manufacturer of
the battery charger you are using.
Special procedures may be
required to charge some
batteries. Contact your ap-
proved dealer.
Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well-venti-
lated area. Risk of serious injury.
Handle the battery with care
as it contains sulphuric acid,
which must not come into
contact with eyes or skin. If
it does, wash the affected area with
plenty of cold water.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
The engine may be hot when car-
rying out operations in close prox-
imity. In addition, the engine cooling
fan can come on at any moment.
Risk of injury.
