ENGINE OIL LEVEL: general information
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 make sure
that the maximum level has not been
exceeded (risk of engine damage).
Refer to the following pages.

B
A
B
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 con-
verter.
If the oil level exceeds the maximum
level, do not start your vehicle .
Contact an authorised dealer.
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.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
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 fall below minimum mark A or exceed
maximum mark 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.

ENGINE OIL LEVEL: topping up, filling (1/3)
Topping up/Filling
The vehicle must be parked on level
ground and the engine should be cold
(for instance, before the engine is
started up for the first time in the day). – Unscrew cap 1;
– top up the level (as a guide, the ca-
pacity between the minimum and
maximum reading on the dipstick 2
is between 1.5 and 2 litres, depend-
ing on the engine);
– wait for approximately 20 minutes to allow the oil to flow into the engine;
– check the level using the dipstick 2
(as described above).
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.
Do not exceed the max level and
do not forget to refit cap 1 and dip-
stick 2.

Brake fluid level
This should be checked frequently,
and immediately if you notice even the
slightest loss in braking efficiency.
The level should be read with the engine
switched off and on level ground. Level
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 shown on brake fluid reser-
voir 1.
If you wish to check the disc and drum
wear yourself, you should obtain the
document explaining the checking pro-
cedure from the approved dealer net-
work or from the manufacturer’s web
site.
The engine may be hot
during operations in close
proximity. In addition, the
engine cooling fan may
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.
Topping up

Coolant
With the engine switched off and on
level ground, the level when cold must
be between the MINI and MAXI marks
on reservoir 2.
Top this level up when cold before it
reaches the MINI mark.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Checking intervals
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;
– anti-corrosion protection of the cool- ing system.
Replacement intervals
Refer to the Maintenance Service
Booklet for your vehicle.
Consult an approved dealer at once
if you notice an abnormal or re-
peated drop in any of the fluid levels.
