WARNING

This coolant is premixed with 50% antifreeze and 50% water. Do not add any

straight antifreeze or water.

Removing the reserve tank cap while the

engine is hot can cause the coolant to spray

out, seriously scalding you.

We recommend you check the engine coolant level every time you refuel. Check the

reserve tank. Add the engine coolant accordingly.

Always let the engine and radiator cool

down before removing the reserve tank

cap.

Checking the Coolant

■

1. Make sure the engine and radiator are cool.

2. Check the amount of coolant in the reserve

tank.

u If the coolant level is below the MIN

mark, add the specified coolant until it

reaches the MAX mark.

MAX

If Honda antifreeze/coolant is not available, you may

use another major brand of non-silicate coolant as a

temporary replacement. Check that it is a high quality

coolant recommended for aluminium engines.

Continued use of any non-Honda coolant can result

in corrosion, causing the cooling system to

malfunction or fail. Have the cooling system flushed

and refilled with Honda antifreeze/coolant as soon as

possible.

3. Inspect the cooling system for leaks.
