Important safety notes
Your vehicle regulates its height
automatically. All-round self-leveling ensures
the best possible suspension and constant
ground clearance, even with a laden vehicle.

automatically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible on
vehicles without 4MATIC:
R normal
R raised: the vehicle is raised by about 1.00
in (25 mm) when compared with the normal
level
R lowered: the vehicle is lowered by about
0.60 in (15 mm) when compared with the
normal level
The following vehicle levels are possible on
vehicles with 4MATIC:
