Engine oil
Checking the engine oil level 1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach normal operating temperature.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully.
WARNING - Radiator hose Be very careful not to touch the radiator hose when checking or adding the engine oil as it may be hot enough to burn you.
5. Pull the dipstick out again and check the level. The level should be between F and L.
If it is near or at L, add enough oil to bring the level to F. Do not overfill.
Use only the specified engine oil. (Refer
to “Recommended Lubricants” later in
this section.)
