[SanBrooklyn]

The method to check the engine oil level in a Volkswagen Touareg is: 1. Turn on the car's ignition switch. 2. Press the CAR button on the infotainment system. 3. Lightly press the Service button on the function panel, and the engine oil level will be displayed on the car's function panel. Extended content: The functions of engine oil are: 1. Friction reduction. A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear between car components. 2. Sealing effect. The oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing the entry of external contaminants. 3. Cleaning effect. The oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and the flow of the lubricant washes away dirt generated on the working surfaces of the parts.
