Coolant
With the engine switched off and on
level ground, the level when cold must
be between the “MINI" and "MAXI"
marks on coolant reservoir 1.
Top this level up when cold before it
reaches the MINI mark. 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;
– anticorrosion protection of the cool -
ing system.
No operations should be
carried out on the cooling
circuit when the engine is
hot.
Risk of burns.
Consult your approved dealer at
once if you notice an abnormal or
repeated drop in any of the fluid
levels.
1Replacement intervals
Refer to the Maintenance Service
Booklet for your vehicle.
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.

maintenance.label A
Observe the indications on the battery:
– 2 naked flames and smoking forbid -
den;
– 3 eye protection required;
– 4 keep away from children;

Battery
The battery is a specific
type , please ensure it is
replaced with the same
type. Consult an approved
dealer.
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. If necessary,
consult a doctor.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
BA tteR y
Depending on the vehicle, a system
continuously checks the battery charge
status. If the level drops, the message
“Battery low start engine ” is displayed
on the instrument panel. In this case,
start the engine. Then the message
“ Battery charging ” appears on the in -
strument panel for the duration of the
charging time.
The charge status of your battery can
decrease especially if you use your ve-
hicle:
– for short journeys;
– for driving in town;
– when the temperature drops;
– after extended use of consumers
(radio etc.) with the engine switched
off.
Replacing the battery
As this operation is complex, we advise
you to contact an approved Dealer.

radiator: If there is a significant lack of coolant, remember that it must never be topped up using cold coolant while
the engine is very warm. After any procedure on the vehicle which has involved even partial draining of the cooling
system, it must be refilled with a new mixture prepared in the correct proportions. Reminder: only products approved
by our Technical Department may be used for this purpose.
