566 7-3. Do-it-yourself maintenance
WARNING
■ When the EV system is hot Do not touch the radiator as they may be hot and cause serious
injuries, such as burns.
■ When the electric cooling fan are operating
Do not touch the motor compartment.
With the power switch in ON, the electric cooling fan may automatically start to run if the air conditioning is on and / or the coolant temperature is high. Be sure the
power switch is OFF when working near the electric cooling fan or radiator grille.
Checking the power control unit coolant
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 performance of the traction battery cooling system and limit risks of battery short circuit and other damage to your vehicle, SUBARU recommends using“ Genuine Traction Battery Coolant” or similar high-quality
ethylene glycol-based, low electric conductivity coolant, non-amine and non-borate coolant with azole additives.
SUBARU cannot guarantee that the use of a product other than“ Genuine 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, contact 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 system.
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 coolant if the cap is removed, causing serious injuries, such as burns.
