Adding engine oil
1. Check the engine oil. For instructions, refer to
Checking the engine oil in this chapter.
2. If the engine oil level is not within the normal
range, add only certified engine oil of the
recommended viscosity. Remove the engine oil filler
cap and use a funnel to pour the engine oil into the
opening.
3. Recheck the engine oil level. Make sure the oil
level is not above the MAX mark on the engine oil
level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the
filler cap clockwise until three clicks can be heard.
To avoid possible oil loss, DO NOT operate the
vehicle with the engine oil level indicator
and/or the engine oil filler cap removed.
