■

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.
●
Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
●
Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
High temperature steam or coolant could spray out.
NOTICE
■

When adding engine coolant

Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■

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.
