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.

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
