WARNING
■ To  prevent  an  accident  or  injury   when  inspecting  under  the  hood of
your vehicle
Observe the following precautions. 
Failure to do so may result in serious injury such as burns.
● If  steam  is  seen  coming  from  under  the  hood,  do  not  open  the  ho od  until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the “READY” indi-
cator is 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 rotating parts  such as the
fan, which may lead to fingers or clothing (especially a tie, a  scarf or a muf-
fler) getting caught, resulting in serious injury.
● Do  not  loosen  the  radiator  cap  and  the  coolant  reservoir  cap  wh ile  the
hybrid system and radiator are hot.
High temperature steam or coolant could spray out.
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 sa nd or dust
etc.).
● Do not use any coolant additives.
