6 If the coolant is insufficient,
replenish with “Toyota Genuine
Traction Battery Coolant”.
If you don’t have “Toyota Genuine Trac-
tion Battery Coolant”, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
1 Remove the bolt.
2 Open the reservoir cap.
Have the vehicle inspected at the
nearest authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer as soon as
possible.
WARNING
■To prevent an accident or injury when inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the hood, do not open the hood
until the steam has subsided. The motor compartment may be very hot.
●Keep hands and clothing (espe-cially a tie, a scarf or a muffler)
away from the fan. Failure to do so may cause the hands or clothing to be caught, resulting in serious
injury.
●Do not loosen the coolant reservoir
cap while the EV system and radia- tor are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding coolant
Add coolant slowly after the EV sys-
tem has cooled down sufficiently. Adding cool coolant to a hot EV sys-tem too quickly can cause damage to
the EV system.
■To prevent damage to the cooling
system
Observe the following precautions:
●Avoid contaminating the coolant
with foreign matter (such as sand or dust, etc.).
●Do not use water or any other cool-ant when refilling coolant. Also, do not use any additive agents for the
coolant.
