A buzzer sounds in accordance with the warning 
message that is displayed.
Indicates that the high engine coolant tempera-
ture is too high
  Indicates abnormal engine oil pressure
A buzzer also sounds.
The warning message is shown if the engine oil 
pressure is too low.

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 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 fin-
gers or clothing (especially a tie, a scarf or a muffler) getting caught,
resulting in serious injury.
● Do not loosen the radiator cap while the hybrid system and radiator 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.).
● When using coolant additives, use genuine Toyota products or equivalent. 

496 6-1. Specifications
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.

Coolant type Use either of the following:
• “Toyota Super Long Life Coolant” 
• A similar high-quality ethylene glycol-based non-silicate, non-amine, non-nitrite, 
and non-borate coolant with long-life 
hybrid organic acid technology
Do not use plain water alone.
