Maintenance and care
The coolant level is satisfactory
if it is between the “MAX” and
“MIN” lines on the reservoir
when the EV system is cold.
Reservoir cap
“MAX” line
“MIN” line
If the level is on or below the “MIN”
line, add coolant up to the “MAX”
line.
■ Coolant selection
In order to ensure maximum perfor-
mance of the traction battery cooling
system and limit risks of battery
short-circuit and other damage to
your vehicle, SUBARU recom-
mends using “Genuine Traction Bat-
tery Coolant” or similar high-quality
ethylene glycol-based, low electric
conductivity coolant, non-amine and
non-borate coolant with azole addi-
tives.
SUBARU cannot guarantee that the
use of a product other than “Genu-
ine Traction Battery Coolant” will
prevent risks of battery short-circuit
or other damage.
Never use water as it will cause
damage.
Do not reuse coolant that has been
removed from the radiator.
For more details about coolant, con-
tact your SUBARU dealer.
■ If the coolant level drops within
a short time of replenishing
Visually check the hoses, heater
coolant reservoir caps, drain cock
and water pump.
If you cannot find a leak, have your
SUBARU dealer, test the cap and
check for leaks in the cooling sys-
tem.
WARNING
■ When the electric cooling fan
are operating
Do not touch the motor compart-
ment.
With the power switch in ON, the
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. Be sure the
power switch is OFF when work-
ing near the electric cooling fan or
radiator grille.
Checking the power con-
trol unit coolant
WARNING
■ When the EV system is hot
Do not remove the power control
unit coolant reservoir caps.
The cooling system may be under
pressure and may spray hot cool-
ant if the cap is removed, causing
serious injuries, such as burns.
