Maintenance and care
CAUTION
■
When raising your vehicle
Make sure to observe the following to reduce the possibility of death or\
seri-
ous injury.
●When using a floor jack, follow the instructions of the manual provided with
the jack.
● Do not put any part of your body or get underneath the vehicle supported
only by the floor jack.
● Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
● Do not start the EV system while the vehicle is supported by the floor jack.
● Stop the vehicle on level, firm ground, firmly set the parking brake and
push the “P” position switch.
● Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
● Do not raise the vehicle while someone is in the vehicle.
● When raising the vehicle, do not place any objects on top of or underneath
the floor jack.
●Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

CAUTION
■Tire jack usage
■ When using jack stands
●Do not use a tire jack because its arms
may interfere with the traction battery in
the vehicle underbody.
● Forcibly using a tire jack may damage
the traction battery or cause the vehicle
to fall off the jack, resulting in death or
serious injury.
Inside
When lowering the vehicle onto jack
stands, do not let the jack stands contact
the traction battery or undercover. Doing
so may damage the vehicle underbody.
Working on the vehicle while a jack stand
is contacting the traction battery is partic-
ularly dangerous because it may not only
damage the traction battery, but the vehi-
cle may fall, causing an accident that
results in death or serious injury.

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.
Reservoir cap
“F”
“L”
If the level is on or below the “L”
line, add coolant up to the “F” line.
(P. 485)

358 4-3. Do-it-yourself maintenance
■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 or traction battery coolant reser-
voirs. 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.
Reservoir cap
“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.

Condenser and radiatorsCheck the condenser and radiator s, and clear away any foreign
objects.
If either of the above parts are ex tremely dirty or you are not sure of
their condition, have your vehicl e checked by your Toyota dealer.

corrosion protection. Be sure to read the antifreeze or coolant label.
● Do not add motor or traction battery coolant to the heater coolant reser-
voir. Doing so will negatively affect the coolant’s performance and cause
the heater system to malfunction.

CAUTION
■When the EV system is hot
Do not touch the condenser or radiators as they may be hot and cause seri-
ous injuries, such as burns.
