Maintenance and care
Motor/traction battery coolant
Motor coolant reservoir
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the EV system is cold.
Reservoir cap
“FULL”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line. (P. 485)
Traction battery coolant reservoir
The coolant level is sati sfactory if it is between the “F” and “L” lines on
the reservoir when the EV system is cold.
“F”
“L”
Contact your Toyota dealer if the
level is on or below the “L” line.
The reservoir cap is not intended
to be opened by the user.
Improper filling can lead to trac-
tion battery system damage. Only
qualified personnel should ser-
vice the traction battery coolant.

■Coolant selection
Only use “Zerex G 48” or “Glysantin G 48”.
“Zerex G 48” and “Glysantin G 48” are blue in color.
Reference:
The dilution ratio for both “Zerex G 48” and “Glysantin G 48” is 50% cool-
ant and 50% deionized water. (Minimum temperature: approximately -32 F
[-36 C])
For more details about motor/traction battery coolant, contact your Toyota
dealer.
■ If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, motor/traction battery coolant reservoir
cap, drain cock and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.
CAUTION
■When the EV system is hot
Do not remove the coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
●Coolant is neither plain water nor straight antifreeze. The correct mixture
of water and antifreeze must be used to provide proper lubrication, corro-
sion protection and cooling. Be sure to read the antifreeze or coolant label.
● Do not add heater coolant to the motor coolant reservoir. Doing so will
negatively affect the coolant’s performance and cause the cooling system
to malfunction.
■ If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.

Maintenance and care
Heater coolant
The coolant level is sati sfactory if it is between the “F” and “L” lines on
the reservoir when the heater system is cold.

“F”
“L”
If the level is on or below the “L”
line, add coolant up to the “F” line.
(P. 485)
■ Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is pink in color.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Minimum temperature: -31 F [-35 C])
For more details about heater coolant, contact your Toyota dealer.
■ If the coolant level drops within a short time after replenishing
Visually check the hoses, heater coolant reservoir cap, drain cock and water
pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the heater system.
CAUTION
■When the heater is in use or just after use
Do not remove the coolant reservoir cap.
The heater system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.

5-2. Steps to take in an emergency
If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition-
ing system.
Check to see if steam is coming out from under the hood.
If you see steam: Stop the EV system. Carefully lift the hood after the steam
subsides and then restart the EV system.
If you do not see steam: Leave the EV system operating and carefully lift the hood.
Check to see if the cooling fans are operating.
If the fans are operating: Wait until “High Battery Temp” disappears and then stop the
EV system.
If the fans are not operating: Stop the EV system immediately and contact your Toyota
dealer.
After “High Battery Temp” disap-
pears, check the motor/traction
battery coolant level and inspect
the cooling system for leaks.
There are 2 powertrain coolant
reservoirs. Make sure to check
both of them. (P. 357)
If “High Battery Temp” is shown on the multi-information display, the
vehicle may be overheating.
If the message does not disappear after driving for a little while, fol-
low the correction procedu re as described below.
