3 After the hybrid system has
cooled down sufficiently, inspect
the hoses and radiator core
(radiator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks, immediately contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
4 The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL” line
“LOW” line
5 Add coolant if necessary.
Water can be used in an emergency if
engine coolant is unavailable. If water was added in an emergency,
have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
6 Start the hybrid system and turn
the air conditioning system on to
check that the radiator cooling
fan operates and to check for
coolant leaks from the radiator
or hoses.
The fan operates when the air condi- tioning system is turned on immediately
after a cold start. Confirm that the fan is operating by checking the fan sound and air flow. If it is difficult to check
these, adjust the temperature control switch to “LO” and turn the “A/C” switch ON and OFF. After this, turn the air
conditioning system on and off repeat- edly. (The fan may not operate in freez-ing temperatures.)
7 If the fan is not operating:
Stop the hybrid system immedi-
ately and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
If the fan is operating:

WARNING
■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 hood until the steam has subsided. The engine compartment may be very
hot.
●After the hybrid system has been
turned off, check that the “READY” indicator is off.When the hybrid system is operat-
ing, the gasoline engine may auto- matically 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 muffler) getting caught, result-ing in serious injury.
●Do not loosen 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 con-trol 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 dam- age to the hybrid system.
■To prevent damage to the cool-ing system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust, etc.).
●Do not use any coolant additive.
