ENGINE OIL LEVEL INSPECTION
1. Park the vehicle on a level, horizontal surface.
2. Warm up the engine.
If the vehicle has been parked for a long time, warm up the engine for approximately 20 minutes.
3. Stop the engine, wait 2 - 3 minutes, and then check the engine oil level.

4. Check that the engine oil level is within the allowable range indicated on the engine oil dipstick. If the engine oil level is near or below the minimum level ("L" mark), add oil up to the "F" mark.
Use engine oil of the same type as the oil already in the engine.
5. Check that the engine oil is not contaminated, and that there is no coolant or gasoline in the oil. Check that the engine oil has the correct viscosity.
ENGINE OIL REPLACEMENT

2. Turn the engine off.
3. Remove the oil filler cap and loosen the oil pan drain plug. Drain the engine oil.
4. Install and tighten the drain plug to the specified tightening torque.
