7-2. Steps to take in an emergency
If steam is seen coming from under the
●
hood, do not open the hood until the
steam has subsided. The engine com-
partment may be very hot.
After the hybrid system has been
●
turned off, check that the "READY"
indicator off.
When the hybrid system is operating,
the gasoline engine may automatically
start, or the cooling fan may suddenly
operate even if the gasoline engine
stops. Do not touch or approach rotat-
ing parts such as the fan, 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 inlet cap or
●
the coolant reservoir cap while the
hybrid system and radiator are hot.
High temperature steam or coolant
could spray out.
NOTICE
When adding engine/power control
■
unit coolant
Add coolant slowly after the hybrid sys-
tem 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 sys-
■
tem
Observe the following precautions:
Avoid contaminating the coolant with
●
foreign matter (such as sand or dust
etc.).
Do not use any coolant additive.
