3. Engine Oil

A: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and properly
orientated.
4) Remove it again and check the engine oil level. If
the engine oil level is below "L" line, add oil to bring
the level up to "F" line.
5) After turning off the engine, wait a few minutes
for the oil to return to the oil pan before checking
the level.
6) Just after driving or while the engine is warm, en-
gine oil level show in the range between "F" line
and the notch mark. This is caused by thermal ex-
pansion of the engine oil.
NOTE:
To prevent overfilling the engine oil, do not add oil
above "F" line when the engine is cold.
