Mercedes-Benz M-Class 2013 Owners Manual - Manual (Page 213)

The vehicle level may change visibly if you
park the vehicle and the outside temperature
changes. If the temperature drops, the
vehicle level is lower; with an increase in
temperature, the vehicle level rises.
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.
Basic settings
The extent to which the vehicle is raised or
lowered depends on the basic setting
selected. Select raised level for off-road
driving or highway/high-speed level for
normal roads.
The individual vehicle levels differ from
highway level as follows:
R highway level: +/–0 in (+/–0 mm)
R high-speed level: –0.6 in (–15 mm)
R raised level: +2.3 in (+60 mm)
Raised level
Only select raised level if this is appropriate
for the road conditions. Otherwise, fuel
consumption may increase and handling may
be affected.
