Checking the antifreeze and coolant level

Warning

Danger of scalding

During motorcycle operation, the coolant gets very hot and is under pressure.

–

Do not remove the radiator cap, radiator hoses or other cooling system components when the engine is hot. Allow the
engine and cooling system to cool down. In case of scalding, rinse immediately with lukewarm water.

Warning

Danger of poisoning

Coolant is poisonous and a health hazard.

–

Coolant must not come into contact with the skin, eyes, or clothing. If contact occurs with the eyes, rinse with water imme-
diately and contact a physician. Immediately clean contaminated areas on the skin with soap and water. If fuel is swal-
lowed, contact a physician immediately. Change clothing that is contaminated with coolant. Keep coolant out of reach of
children.

Condition

The engine is cold.
