The vehicle must be level when measuring.
After turning off the engine, wait at least 3 minutes for the oil to drain into the crankcase.
Pull out the dipstick and wipe it with a clean cloth.
Then insert the probe into the guide tube as far as it will go. The oil level must be between the two marks.
Add fresh oil when the oil level approaches the lower mark. It takes about 1 liter of oil to raise the level from the lower mark to the upper one. Topping up the oil is done through the neck on the valve cover.
Attention: Do not overfill oil above the upper mark. Overfilling increases oil consumption and can damage the engine and catalytic converter.
