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.
●
Keep hands and clothing away from the fans, etc., while the engine is run-
ning.

Do not loosen the radiator cap and the coolant reservoir cap while the
engine and radiator are hot.
High temperature steam or coolant could spray out.

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.
