Setting the specified minimum distance
You can set the specified minimum distance
for DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS keeps to the vehicle in
front, dependent on vehicle speed. You can
see this distance in the multifunction display
(
Ypage 211).

Driving and parking

DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
Level control (vehicles with the
ON&OFFROAD package)
Important safety notes
Level control adapts the vehicle level auto-
matically to the current operating and driving
situation. This results in reduced fuel con-
sumption and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as pos-
sible.
The vehicle level may change visibly if you
park the vehicle and the outside temperature
changes. If the temperature drops, the vehi-
cle level is lower; with an increase in temper-
ature, the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load dis-
crepancies 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.

Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
GWARNING
When you drive with the vehicle raised, the
driving characteristics could be impaired by
the vehicle's raised center of gravity. The vehi-

cle could rollover more easily, for example on
a bend. There is a risk of an accident.
Always select as low a vehicle level as possi-
ble and adjust your driving style.
GWARNING
When you drive with the chassis lowered or
raised, the vehicle's braking and driving char-
acteristics can be significantly impaired. You
could also exceed the permissible vehicle
height if the chassis is raised. There is a risk of an accident.
Adjust the vehicle level before pulling away.
GWARNING
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road
conditions. There is a risk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the
prevailing road and weather conditions.
!When driving on extremely rough terrain,
select a high vehicle level in good time.
Make sure there is always sufficient ground
clearance. You will otherwise damage the
vehicle.
!When you raise the vehicle in such a way
that not all wheels have contact with the
ground, remove the SmartKey from the
ignition lock.
RUtility vehicles have a significantly higher
rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle, and severe or fatal injury.
RIn a rollover crash, an unbelted person is
significantly more likely to die than a per-
son wearing a seat belt.
You and all vehicle occupants should
always wear your seat belts. General notes

Vehicle level
Level control adapts the vehicle level auto-
matically to the current operating and driving
situation. Level control ensures the best pos-
sible suspension and constant ground clear-
ance, even with a laden vehicle. This improves
driving safety and fuel consumption.
The AIRMATIC package and ACTIVE CURVE
SYSTEM are always components of AMG
adaptive suspension system (
Ypage 218).
Due to the sportier suspension settings com-
pared to standard vehicles, the levels and
speed thresholds for sinking and raising the
vehicle are different.
