Checking the oil level using the oil dipstick
On vehicles with a 12-cylinder engine, the oil level can be checked using the on-board computer. On all other models, the dipstick must be used to check the engine oil level.

Example: vehicles with a gasoline engine

Example: vehicles with 4MATIC
Park the vehicle on a level surface.
To check the oil level with the engine at operating temperature, switch the engine off and wait for approximately five minutes.
Pull oil dipstick 1 out of the dipstick guide
tube.
Wipe off oil dipstick 1.
Slowly slide oil dipstick 1 into the guide
tube to the stop, and take it out again.
If the level is between MIN mark 3 and MAX mark 2, the oil level is correct.
If the fuel level has sunk to MIN mark 3 or
below, add 0.55 to 1.1 US qt (0.5 to 1.0 l)
engine oil.
