|---|---|
| Below the MIN line | Replenish the same type of oil immediately |
| Over the MAX line | Professional oil extraction required |

For vehicles equipped with CVT transmissions, the inspection frequency should be increased to every 10,000 kilometers. If metal debris is found in the oil, it may indicate an internal mechanical failure and requires immediate repair.
