Inspecting Coolant Level
Do not use a match or live flame in the motor compartment. DO NOT ADD COOLANT WHEN THE EV SYSTEM IS HOT:
A hot EV system is dangerous. If the EV system has been running, parts of the motor compartment can become very hot. You could be burned. Carefully inspect the coolant in the coolant reservoir, but do not open it.
Pull over to a safe location, then switch the power switch off and make sure the fan is not running before attempting to work near the cooling fan:
Working near the cooling fan when it is running is dangerous. The fan could continue running indefinitely even if the EV system has stopped and the motor compartment temperature is high. You could be hit by the fan and seriously injured.
Do not remove either cooling system cap when the EV system and radiator are hot:
When the EV system and radiator are hot, scalding coolant and steam may shoot out under pressure and cause serious injury.
Inspect the antifreeze protection and coolant level in the coolant reservoir at least once a year―at the beginning of the winter season―and before traveling where temperatures may drop below freezing.
Inspect the condition and connections of the cooling system.
Replace any that are swollen or deteriorated.
The coolant should be between the FULL and LOW marks on the coolant reservoir when the EV system is cool.
If it is at or near LOW, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to FULL.
Securely tighten the coolant reservoir tank cap after adding coolant.
-
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
-
If the “FL22” mark is shown on or near the cooling system cap, use of FL-22 is recommended when replacing coolant. Using coolant other than FL-22 may cause serious damage to the cooling system.
If the coolant reservoir is empty or new coolant is required frequently, consult an Authorized Mazda Dealer.
