5-2. Steps to take in an emergency
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 indicator on the "POWER" switch and the "READY" indica-
●
tor are off.
On hybrid vehicles, the gasoline engine may automatically start, or the
●
cooling fans may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fans, which may lead to
fingers or clothing (especially a tie, a scarf or a muffler) getting caught,
resulting in serious 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

■
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 any coolant additives other than the Toyota genuine or similar
