Running the engine without coolant causes serious engine damage.
If persistent coolant loss is noticed, seek qualified assistance immediately.
Check the coolant reservoir level at least every week. Check more frequently in high mileage or arduous conditions. Always check the level when the system is cold.
Make sure the coolant level remains between the MIN and MAX indicator marks on the side of the expansion tank.
If the coolant level has dropped suddenly, or by a large amount, arrange for the vehicle to be examined by qualified personnel. Consult a retailer/authorised repairer as soon as possible.
