7-2. Steps to take in an emergency 
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.

5 Add coolant if necessary.
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 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.
