Too full
4. Pull the dipstick out and look at the oil level while holding a
rag under the end. If it is between the full level mark (
5
) and
the low level mark ( 4
), it is O.K.
NOTICE
Be careful not to drop engine oil on the vehicle
components.

If the oil level is below or only slightly above the low level
mark, 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
raise the level between low and full on the dipstick is indicated
as follows:
1.5 L (1.6 qt., 1.3 lmp. qt.)
For the engine oil capacity, see “Specifications” on pages 512
and 515.
When the level reaches within the correct range, return the
filler cap and turn the cap clockwise until you hear a click.
