Checking the oil level in a manual transmission (Hyundai Sonata EF)

1. Place the vehicle on a level, horizontal surface. Check for oil leaks.

2. Unscrew the gearbox filler plug located at the front of the vehicle.



3. The oil level in the crankcase should be at the level of the lower edge of the filler hole (filler plug hole).



4. Check that there is no visible contamination of the oil. Make sure that the oil has the correct viscosity.

Note: If the oil is contaminated, it is necessary to drain the oil and fill it with new transmission oil.

5. If the oil level is below the norm, add the recommended transmission oil until the oil level reaches the bottom of the filler hole.

6. Tighten the filler plug to the specified torque.

• Tightening torque: 30-35 Nm
