A DANGER

SCALD HAZARD!

• NEVER remove the coolant

filler cap if the engine is hot.

Steam and hot engine coolant

will escape and seriously burn

you. Allow the engine to cool

before attempting to remove

the filler cap.

• Securely tighten the filler cap

after checking the coolant

level. Steam can escape during

engine operation if the cap is

loose.

• Failure to comply will result in

death or serious injury.
