1. Open the left-hand door.
2. Withdraw the dipstick, wipe with a lint-free cloth and insert fully.
3. Withdraw the dipstick once more and read off the oil level.
Oil level between both markings: Oil level OK.
The level has reached the
minimum level or is below the mark: Replenish engine oil.
4. Close the door.
The marked
maximum oil level should not be exceeded in order for the level of oil in the
crankcase not to reach the crankshaft. If this were to occur, it could create oil bubbles that
would reduce the oil's lubricating capability and impair engine performance.
