engine is hot, you will get an inaccurate oil level reading.
7. Remove the dipstick ( ) from the oil tank ( ) and wipe it clean.
8. Insert the dipstick without screwing it in, then remove the dipstick and
check the oil level. The oil level should be between the upper level

9. If required, remove the oil filler cap ( ) and add the specified oil into
the oil filler cap hole, up to the upper level mark on the dipstick. Do
not overfill.
