How do you check the oil in a 2005 Mercedes E500?

To check the oil in a 2005 Mercedes E500, first ensure the car is on a level surface and the engine is turned off. Open the hood and locate the oil dipstick, which is usually marked with a yellow or red handle. Pull out the dipstick, wipe it clean with a cloth, reinsert it fully, and then remove it again to check the oil level. The oil level should be between the marked minimum and maximum lines; if it's low, add the appropriate type of oil as specified in the owner's manual.
