and level surface, then check the oil level. If the engine is already
running, turn it off and allow 10 minutes before checking.
• Pull out oil level gauge and wipe clean.
• Insert oil level gauge.
• Check that the oil level is within the low (L) and high (H) range as
indicated on the dipstick.
• If the engine oil level is out of range, add oil as necessary. Refer to
MA-16, "FOR USA AND CANADA : Fluids and Lubricants"
.
CAUTION:
Do not overfill the engine with oil.
NOTE:
It is normal to add some oil between oil maintenance intervals or during the break-in period, depending on
the severity of the operating conditions.
