TIP
The engine oil should be between the “H” and
“L” level marks on the dipstick.

6. If the engine oil is below the “L” level
mark, add sufficient oil of the recom-
mended type to raise it to the “H” level
mark. (See page 122 for the recommend-
ed oil.) NOTICE: When adding the en-
gine oil, be careful not to fill above the
“H” level mark on the dipstick. Use
only the recommended oil. (See page
122.) Make sure that no foreign materi-
al enters the engine oil tank.
