Coolingfluidlevel (03_09, 03_10)
The engine cooling system is of the forced liquid type; the cooling circuit contains
approx. 0.7 litres of coolant, obtained from a mixture of demineralised water (50%)
and a glycol-ethylene based solution with corrosion inhibitors (50%). The recommen-
ded coolant is sold pre-mixed, ready for use.
The system is fitted with a coolant temperature gauge. For the engine to operate within
normal conditions, the temperature gauge must not reach past segments 7 or 8 on
the digital scale.
As segment 10 goes on, the icon and the bars start blinking; is such conditions, stop
the engine, let it cool down and check the coolant level. If this is correct, please contact
an Authorised Piaggio Service Station to fix the cause of the fault.
A coolant level check must be carried out with the engine cold after the 1,000 Km and
every 5,000 Km thereafter, following the procedure below:
a) Rest the vehicle on its centre-stand.
