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 all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.

There are two cooling circuits: one for
the automatic transmission, and the
other for the engine. Check both
circuits.
The coolant should be at full in the
radiator and between the F and L
marks, and between the FULL and
LOW marks on the coolant reservoir
when the engine is cool.
There are two coolant reservoir tanks.
Check each of them.
1. The tank for the EV system
2. The tank for the engine

If it is at or near the LOW position, 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.
CAUTION
 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 engine coolant. Using
engine coolant other than FL-22 may
cause serious damage to the engine
and cooling system.

If the coolant reservoir is empty or new
coolant is required frequently, consult
an Authorized Mazda Dealer.
