POSSIBLE CAUSES
Assistance overheating.
Engine cooling fan not working.
Coolant leaks.
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 drain-
ing 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.
WHAT TO DO
Consult an approved Dealer.
Stop the vehicle, switch off the engine and
contact an approved Dealer.
Check the coolant reservoir: it should con-
tain fluid. If there is no coolant, consult an
approved Dealer as soon as possible.
