NOTE:
The engine oil should be between the mini-
mum and maximum level marks.
4. If the engine oil is below the minimum
level mark, add sufficient oil of the recom-
mended type to raise it to the correct lev-
el.
NOTE:
When adding oil, be careful not to overfill the
engine; the oil level rises faster starting from
the half-level-portion on the dipstick.
5. Insert the dipstick into the oil filler hole,
and then tighten the oil filler cap.
CAUTION:
Make sure that the oil filler cap is securely
tightened, otherwise oil may seep out when
the engine is running.
