215 Operation
The first 1000 miles (1500 km)
All of the above instructions, as may apply
to your vehicle type, also apply when driv-
ing the first 1000 miles (1500 km) after the
engine, the transfer case, the front differ-
ential or the rear differential has been re-
placed.
iG55AMG:
For better protection of the front and
rear differential, the oil must be
changed after a break-in period of
1900 miles (3000 km).
Changing oil in the front and rear
differential increases the service life
and helps reduce noise from the
differential locks.
See Maintenance Booklet for additional
information and Factory Approved
Service Products pamphlet for informa-
tion on the approved service product
required to perform the front and rear
axle oil change.
iAlways obey applicable speed limits.
