Mercedes-Benz 2013 M Class - Manual (Page 207)

If you unlock the vehicle or open a door, the
vehicle begins to compensate for load
discrepancies while still parked. However, for
significant level changes, such as after the
vehicle has been stationary for a long period,
the engine must be on. For safety reasons,
the vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened, and it continues once the door has
been closed.
For information about driving off-road, see
(
Y page 187).
