Correction procedures■ If the needle of the engine coolant temperature gauge enters
the red zone
Stop the vehicle in a safe place and turn off the air condition-
ing 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 if the cooling fans are operating.
If the fans are operating: Wait until the engine coolant temperature gauge begins to
fall and then stop the hybrid system.
If the fans are not operating: Stop the hybrid system immediately and call your Toyota
dealer.
The following may indicate that your vehicle is overheating:
●The needle of the engine coolant temperature gauge enters the
red zone:
The engine may be overheating.
● “Hybrid System Overheat” is shown on the multi-information dis-
play:
The power control unit may be overheating.
Follow the correction procedure as described below.

■
Overheating
The following symptoms may occur when your vehicle is overheating:
●Hybrid system output decreases.
● Steam is coming from the engine area.
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
●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, caus-
ing serious injury such as burns.
● With a hybrid vehicle, there are times when the gasoline engine automati-
cally 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 an accidental injury.
● Do not loosen the coolant reservoir cap while the hybrid system and radia-
tor are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage to the hybrid system.
