5-2. Steps to take in an emergency
If your vehicle overheats
Correction procedures■ If the rightmost segment of th e engine coolant temperature
display are flashing
Stop the vehicle in a safe place and turn off the air condition-
ing 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 radiator core
(radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The following may indicate that your vehicle is overheating.
●The rightmost segment of the engine coolant temperature dis-
play ( P. 178) is flashing or a lo ss of hybrid system power is
experienced. (For example, the vehicle speed does not
increase.)
● “HYBRID SYSTEM OVERHEAT” ( P. 436) is shown on the
multi-informat ion display.
● Steam comes out from under the hood.

478 5-2. Steps to take in an emergency
Start the hybrid system and check for the multi-information
display.
If the message does not disappear:Stop the hybrid system and c ontact your Toyota dealer.
If the message is not displayed: Have the vehicle inspected at the nearest Toyota dealer.
CAUTION
■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.
● Check that on the multi-information display and the “READY” indi-
cator are off.
● On hybrid vehicles, the gasoline engine may automatically start, or the
cooling fans may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fans, 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 commercially available coolant additives.

Lubrication system
*: The engine oil capacity is a reference quantity to be used when changing the
engine oil. Warm up the engine and turn off the hybrid system, wait more
than 5 minutes, and check the oil level on the dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allowscold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (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 label:
The ILSAC (International Lubricant Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.
