NOTICE
D Be careful not to spill the engine oil on the vehicle
components.
D Avoid overfilling, or the engine could be damaged.
D Check the oil level on the dipstick once again after
adding the oil.
If the oil level is below or only slightly above the low line,
add engine oil of the same type as already in the engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. We recommend that you use a funnel
when adding oil. The approximate quantity of oil needed to fill
between the low line and the full line on the dipstick is indicated
below for reference.
When the level reaches within the correct range, return the filler
cap and turn the cap clockwise until you hear a click.
