coolant is unavailable.
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, turn the air conditioning system on and off repeatedly. (The fan may not operate in freezing temperatures.)
7 If the fan is not operating: Stop
the hybrid system immediately
and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
If the fan is operating: Have the
vehicle inspected at the nearest
any authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
If “Hybrid System Overheated
Output Power Reduced” is
shown on the multi-information
display
1 Stop the vehicle in a safe place.
2 Stop the hybrid system and
carefully lift the hood.
3 After the hybrid system has
cooled down, inspect the hoses
and radiator core (radiator) for
any leaks.
If a large amount of coolant leaks, immediately contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

6 After stopping the hybrid system
and waiting for 5 minutes or
more, start the hybrid system
again and check for the multi-
information display.
If the message does not disap-
pear: Stop the hybrid system
and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
If the message is not displayed:
The hybrid system temperature
has dropped and the vehicle
may be driven normally.
However, if the message appears again
frequently, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
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 operating, the gasoline engine may automatically start, or
the cooling fan may suddenly oper- ate even if the gasoline engine stops. Do not touch or approach
rotating parts such as the fan, which may lead to fingers or cloth-ing (especially a tie, a scarf or a
muffler) getting caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps 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 cooling system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or
dust etc.).

WARNING
■During customization
As the hybrid system needs to be operating during customization,
ensure that the vehicle is parked in a place with adequate ventilation. In a closed area such as a garage,
exhaust gases including harmful car- bon monoxide (CO) may collect and enter the vehicle. This may lead to
death or a serious health hazard.
NOTICE
■During customization
To prevent 12-volt battery discharge, ensure that the hybrid system is oper-
ating while customizing features.
