Warnings and Cautionsfor Daily Inspection
WARNING
Do not perform maintenance work if
you lack sufficient knowledge and
experience or the proper tools and
equipment to do the work. Have
maintenance work done by a
qualified technician.
Performing maintenance work on a
vehicle is dangerous if not done
properly. You can be seriously injured
while performing some maintenance
procedures.
If you must run the hybrid system
while working under the hood, make
certain that you remove all jewelry
(especially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose clothing
before getting near the cooling fan
which may turn on unexpectedly.
Working under the hood with the
hybrid system operating is dangerous.
It becomes even more dangerous
when you wear jewelry, loose clothing
or have long hair or a long beard.
Either can become entangled in
moving parts and result in injury.
Pull over to a safe location, then
switch the vehicle power 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 engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not leave items in the motor
compartment.
After you have finished checking or
doing servicing in the engine
compartment, do not forget and leave
items such as tools or rags in the motor
compartment. Tools or other items left
in the engine compartment could
cause the hybrid system damage or a
fire leading to an unexpected accident.
CAUTION
When using a chassis roller, turn the
following systems off to prevent them
from mis-operating while the vehicle is
running on the chassis roller.
 Mazda Radar Cruise Control
(MRCC)
 Mazda Radar Cruise Control with
Stop & Go function (MRCC with

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.
