Correction procedures
If the high engine coolant temperature warning light comes on
or flashes
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 to see if the cooling fan is operating.
If the fan is operating:
Wait until the high engine coolant temperature warning light
goes off and then stop the hybrid system.
If the fan is not operating:
Stop the hybrid system immediately and call any authorized
Toyota dealer or repairer, or another duly qualified and
equipped professional.
The following may indicate that your vehicle is overheating:
The high engine coolant temperature warning light comes on or
flashes:
The engine may be overheating.
If the hybrid system overheat warning light comes on:
The power control unit may be overheating.
Follow the correction procedure as described below.

640 5-2. Steps to take in an emergency
YARIS_F (including HV)_WE_52C79EAfter the hybrid system has
cooled down sufficiently, check
the engine coolant level and
inspect the cooling system for
leaks.
Add engine coolant if necessary.
Water can be used in an emer-
gency if engine coolant is unavail-
able. (P. 667)
Have the vehicle inspected at the nearest authorized Toyota dealer or
repairer, or another duly qualified and equipped professional as soon
as possible.

Overheating
The following symptoms may occur when your vehicle is overheating:
Hybrid system output decreases.
Steam comes out 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 injuries such as burns.
Check that the “READY” indicator is off.
For vehicles with a hybrid system, there are times when the gasoline
engine automatically starts to run or the cooling fan suddenly start to oper-
ate. Do not touch or approach the rotating parts of the belt or fan. Doing so
may lead to fingers, clothes or tools getting caught, resulting in injury.
Do not loosen the coolant reservoir cap while the hybrid system and radia-
tor are hot.
Serious injuries, 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.
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
