perature warning light ( P. 518) comes on or flashes, or a loss of
hybrid system power is experienced. (For example, the vehicle
speed does not increase.)
Vehicles with color display:
• The needle of the engine coolant temperature gauge ( P. 1 1 7 )
enters the red zone or a loss of hybrid system power is experi-
enced.
(For example, the vehicle speed does not increase.)
• The warning message indicating overheat is shown on the multi-
information display. ( P. 531)
● Vehicles with monochrome display: If the hybrid system overheat
warning light ( P. 522) comes on.
Vehicles with color display: If the warning message indicating over-
heat is shown on the multi-information display. ( P. 535)
● Steam comes out from under the hood.
The following may indicate that your vehicle is overheating:

■If the high engine coolant temperature warning light comes on
or flashes
Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has
cooled down sufficiently,
inspect the hoses and radia-
tor core (radiator) for any
leaks.

Cooling fan
If a large amount of coolant
leaks, immediately contact any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
The coolant level is satisfac-
tory if it is between the
“FULL” and “LOW” lines on
the reservoir.

Start the hybrid system and check for the hybrid system overheat
warning light (with monochrome display) or warning message
(with color display).
If the warning light (with monochrome display) or warning mes-
sage (with color display) does not go off:
Stop the hybrid system and contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
If the warning light (with monochrome display) or warning mes-
sage (with color display) goes off:
Have the vehicle inspected at the nearest any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■ To prevent an accident or injury when inspecting under the hood of
your vehicle
● 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, caus-
ing serious injuries such as burns.
● After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automati-
cally 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 reservoir cap while the hybrid system and radia-
tor are hot.
Serious injuries, such as burns, may result from hot coolant and steam
released under pressure.

NOTICE
■When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage 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.).
● Do not use any coolant additives.

■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 oil is not avail-
able, SAE 5W-30 oil may be
used. However, it should be
replaced with SAE 0W-20 at the
next oil change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become difficult
to start, so SAE 0W-20 or
5W-30 engine oil is recom-
mended.
Temperature range anticipated
before next oil change.
