Engine Oil
INSPECTION
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe away the oil.
3) Reinsert the oil level gauge all the way. Be sure that the oil level gauge is correctly inserted and properly orientated.
4) Remove the oil level gauge again and check the reading. If the engine oil level is below line, add oil to bring the level up to "F line.
5) Start the engine and warm it up for a time.
6) After turning off the engine, wait a few minutes for the oil to return to the oil pan before checking the level.
7) Just after driving or while the engine is warm, engine oil level shows in the range between "F line and notch mark. This is caused by thermal expansion of engine oil.
NOTE:
^ To prevent overfilling of engine oil, do not add oil above "F line when the engine is cold.
^ As the oil level gauge is used for daily maintenance, the upper level and the lower level is set assuming that the engine is cold.
