When trouble arises
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam subsides and
then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the instrument
panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radia-
tor) for any leaks.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
able. (P. 709)

Have the vehicle inspected at the nearest any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional
as soon as possible.
Overheating
If you observe the following, your vehicle may be overheating:
Vehicles without a multi-information display: The high engine coolant tem-
perature warning light comes on or a loss of power is experienced.
Vehicles with a multi-information display: The high engine coolant tempera-
ture gauge enters the red zone or a loss of power is experienced.
Steam comes out from under the hood.
CAUTION
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 engine compartment may be very hot.
Keep hands and clothing away from the fans, etc. while the engine is oper-
ating.
Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
NOTICE
When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
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 commercially available coolant additives.

When trouble arises
The high engine coolant temperature display is shown on the multi-
information display:
The engine may be overheating.
“Hybrid System Overheat” is shown on the multi-information dis-
play:
The power control unit may be overheating.
If the high engine coolant temperature display is shown on the
multi-information display
Stop the vehicle in a safe place and turn off the air conditioning
system.
Check to see if steam is coming out from the engine area.
If you see steam:
Stop the hybrid system. Carefully lift the hood after the steam
subsides and then restart the hybrid system.
If you do not see steam:
Leave the hybrid system operating and carefully lift the hood.
Check to see if the cooling fans are operating.
If the fans are operating:
Wait until the high engine coolant temperature display disap-
pears and then stop the hybrid system.
If the fans are not operating:
Stop the hybrid system immediately and call any authorized
Toyota dealer or repairer, or another duly qualified and equipped
professional.
If your vehicle overheats (hybrid model)

gency if engine coolant is
unavailable. (P. 709)
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional as
soon as possible.

Overheating
If you observe the following, your vehicle may be overheating:
The high engine coolant temperature is shown on the multi-information dis-
play or a loss of power is experienced.
“Hybrid System Overheat” is shown on the multi-information display.
Steam comes out from under the hood.
CAUTION
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 engine compartment may be very hot.
Keep hands and clothing away from the fans, etc. while the hybrid system
is operating.
For vehicles with a hybrid system, there are times when the gasoline
engine automatically starts to run or the cooling fans suddenly start to
operate. Do not touch or approach the rotating parts of the belt or fans.
Doing so may lead to fingers, clothes or tools getting caught, resulting in
injury.
Do not loosen the coolant reservoir caps while the hybrid system and radi-
ator are hot.
High temperature steam or coolant could spray out.
NOTICE
When adding engine/power control unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently.
Adding cool coolant to a hot hybrid system too quickly can cause damage to
the hybrid 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 commercially available coolant additives.
