Cooling Fluid Level - APRILIA tuono v4 Owner's Manual

Cooling fluid level

Do not use the vehicle if the coolant is below the minimum level.
CAUTION
COOLANT IS TOXIC IF INGESTED; CONTACT WITH YOUR EYES OR SKIN MAY
CAUSE IRRITATION. IF THE FLUID GETS IN CONTACT WITH THE EYES OR
SKIN, RINSE REPEATEDLY WITH PLENTY OF WATER AND SEEK MEDICAL
ADVICE. IF SWALLOWED, INDUCE VOMITING, RINSE MOUTH AND THROAT
WITH PLENTY OF WATER AND SEEK MEDICAL ADVICE IMMEDIATELY.
Coolant solution is 50% water and 50% antifreeze fluid.
This is the ideal mixture for most operating temperatures and provides good corrosion
protection.
It is advisable to use the same mixture even in hot weather as this minimises loss due
to evaporation and the need of frequent top-ups.
Less water evaporation means fewer mineral salts depositing in the radiators, which
helps preserve the efficiency of the cooling system.
If the external temperature drops below 0 °C (32 °F), check the cooling system fre-
quently and add more antifreeze fluid if needed (up to 60% max.).
Use distilled water in the coolant mixture to avoid damaging the engine.
