turn the air conditioning sys-
tem on to check that the radi-
ator cooling fans operate and
to check for coolant leaks
from the radiator or hoses.
The fans operate w hen the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fans are operating by
checking the fan sound and air flow.
If it is difficult to check these, turn
the air conditioning system on and
off repeatedly. (The fans may not
operate in freezing temperatures.)

Stop the hybrid system
immediately and contact your
Toyota dealer.
If the fans are operating:
Have the vehicle inspected at
the nearest Toyota dealer.

WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions. 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
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●After the hybrid system has
been turned off , check that the
“READY” indicator is off. When
the hybrid system is operating,
the gasoline engine may auto-
matically start, or the cooling
fans 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 muffler) getting caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir caps while the hybrid sys-
tem 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 system 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 system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.

WARNING
■During customization
As the hybrid system needs to be
operating during customization,
ensure that the vehicle is parked
in a place with adequate ventila-

garage, exhaust gases including
harmful carbon monoxide (CO)
may collect and enter the vehicle.
This may lead to death or a seri-
ous health hazard.

charge, ensure that the hybrid
system is operating while custom-
izing features.
