AMG vehicles with rear axle locking differential
Your vehicle is equipped with a self-locking differential on the rear axle. For better protection of the differential on the rear axle, carry out an oil change after a breaking-in phase of 2000 miles (3000 km). This oil change extends the service life of the differential. Have the oil change carried out at a qualified specialist workshop. Mercedes- Benz recommends that you use an authorized Mercedes-Benz Center for this purpose.
