NOTICE

■ When adding engine coolant

Wait until the engine has cooled down before adding engine coolant.

When adding coolant, do so slowly. 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.
