CAUTION

■

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.

●

Check that the indicator on the “POWER” switch and the “READY” indicator 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 fingers 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.

High temperature steam or coolant could spray out.

NOTICE

■

When adding engine/power control 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 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.
