Running-in notes

The first 1,500 km

If you treat the engine with sufficient care from the very start, you will be rewarded with excellent performance for the remainder of the engine's life.

  • You should therefore drive at varying road and engine speeds for the first 1,500 km.

  • Avoid heavy loads, e.g. driving at full throttle, during this time. Do not exceed 2/3 of the maximum permissible engine speed for each gear.

  • Change gear in good time.

  • Do not shift down a gear manually in order to brake.

  • Try to avoid depressing the accelerator pedal beyond the pressure point (kickdown).

  • Only use ranges 3, 2 or 1 for slow driving, e.g. in mountainous terrain.

After 1,500 km you may gradually bring the vehicle up to full road and engine speeds.

Additional driving tips for AMG vehicles:

  • Do not drive faster than 140 km/h for the first 1,500 km.

  • Only bring the engine up to a maximum speed of 4,500 rpm for a brief period.

  • It is advisable to select drive program C for comfort mode.

You should also observe these notes if the engine or rear axle transmission on your vehicle has been replaced.
