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
upper hole on the engine oil level dipstick.
4. Install the dipstick 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 dipstick and/or the engine oil filler cap removed.
