Warning and Cautions for Using the e-SKYACTIV PHEV
The hybrid system has high voltage areas and high temperature areas. Labels
indicating the cautions on use are applied to these areas. Always follow the
instructions on the label and use the vehicle correctly.
WARNING

remove any high voltage parts.
The following areas contain high voltage parts and may cause electrical shock if
touched.
1. Motor
2. High voltage battery
3. Onboard charger
4. AC Power Outlet (120 V/1,500 W)
5. Warning label example

When inserting/pulling out the
charge connector and the charge
plug, do not twist them excessively.
 Do not apply excessive force to the
connected charge connector such as
by applying your weight.
 Keep objects which generates
intense heat (such as a heater or
cigarette) away from the charge
cable.
 Do not apply orga nic solvents, acid
or alkaline agents to the charge
cable.
CAUTION
 Do not connect the booster cable to
the lead-acid battery or remove the
lead-acid battery while charging the
high voltage battery. Otherwise, the
vehicle or charging device could be
damaged.
 If the charge connector is removed
after the charging is
finished, close
the charging port cap immediately. If
the charging port lid is closed with
the charging port cap open, water or
foreign matter may enter the
charging inlet causing a malfunction.
 Always make sure that the charge
cable is not connected to the vehicle
before driving. If the charge
connector is connected correctly, the
vehicle cannot be driven. However, if
it is not connected completely, the
vehicle can be driven, which could
result in an accident.
 If the charging port is frozen shut,
defrost the port using a hair dryer. If
the charge cable is inserted/pulled
out with the charging inlet frozen, it
could cause damage.

CAUTION
Do not use organic solvents to clean
the seat. It may damage the seat
surface and the heater.
 (second-row)
Before folding a second-row
seatback, make sure that the
second-row seat warmer switch is
off. If a second-row seatback is
folded while the second-row seat
warmer is in operation, it may heat
the seat excessively and damage the
seat surface.

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.
