Coolant
With the engine switched off and on
level ground, the level when cold
must be between the « MINI » A and
« MAXI » B marks on coolant reser -
voir 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.

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.
