Owner’s Manual” is shown on
the multi-information display.
If the message does not disap-
pear:
Stop the hybrid system and con-
tact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
If the message is not displayed:
Have the vehicle inspected at
the nearest authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
■If “Hybrid System Overheated
Output Power Reduced” is
shown on the multi-informa-
tion 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.
4 The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.

5 Add coolant if necessary.
Water can be used in an emergency if power control unit coolant is unavail-able.
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.

mation 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 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.

6229-1. Specifications
before next oil change
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 indicates the
characteristic of the oil which
allows cold startability. Oils with
a lower value before the W allow
for easier starting of the engine
in cold weather.
• The 16 in 0W-16 indicates the
viscosity characteristic of the oil
when the oil is at high tempera-
ture. An oil with a higher viscos-
ity (one with a higher value) may
be better suited if the vehicle is
operated at high speeds, or
under extreme load conditions.
How to read oil container labels:
Either or both API registered marks
are added to some oil containers to
help you select the oil you should
use.API Service Symbol
Top portion: “API SERVICE SN” means
the oil quality designation by American
Petroleum Institute (API).
Center portion: “SAE 0W-16” means
the SAE viscosity grade.
Lower portion: “Resource-Conserving”
means that the oil has fuel-saving and
environmental protection capabilities.
ILSAC Certification Mark
The International Lubricant Specifica-
tion Advisory Committee (ILSAC) Certi-
fication Mark is displayed on the front of
the container.
*: The coolant capacity is the quantity of reference.

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.
