Start the engine and let it run at high speed (about 2500 rpm), until the oil pressure warning light goes out (about 5 seconds). Turn off the engine.
After 5 minutes, check the engine oil level using the dipstick.
Close the flap in the lower engine compartment cover under the oil pan and use a Phillips head screwdriver to turn the locking screw ¼ turn to secure the flap.
After the test drive, check the tightness of the drain bolt and oil filter and tighten them if necessary.
Turn off the warm engine and after 2 minutes check the oil level again, add oil if necessary.
If necessary, reset the service indicator. This requires a special expensive device, so you should contact a workshop for this operation.
To better control the operation and condition of the engine, it is better to use the same grade and brand of oil when changing the oil that was in the engine before. It is recommended to stick a special plate indicating the characteristics of the oil.
Avoid mixing different grades of oil, as motor oils of the same type but different brands may not be compatible. You can add a small amount of oil of the same viscosity, but only as a last resort.
