WARNING
■ When the EV system is hot Do not touch the radiator or condenser 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 .
