LEVELS (1/3)
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 coo- ling 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 Document 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.
Before performing any
action in the engine com-
partment, the ignition must
be switched off by pressing
the engine stop button (please see
the information on “Starting, stop-
ping the engine” in Section 2).

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