DANGER

SCALD HAZARD!

• NEVER remove the radiator cap if the

engine is hot. Steam and hot engine
coolant will spurt out and seriously
burn you. Allow the engine to cool
down before you attempt to remove
the radiator cap.

• Securely tighten the radiator cap after

you check the radiator. Steam can
spurt out during engine operation if
the cap is loose.

• ALWAYS check the level of the engine

coolant by observing the reserve tank.

• Failure to comply will result in death or

serious injury.
