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.
G WARNING
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.
G WARNING
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. R
Utility 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. R
In 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
Further information about "Driving off-road"
( Y
page 198).
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.
If y
ou select ADS comfort mode ( Y
page 218),
the vehicle is lowered to high-speed level as
the speed increases. As the vehicle speed
decreases, the vehicle is raised back up to
highway level.
If you select ADS sport mode ( Y
page 218),
the vehicle skips highway level and lowers
directly to high-speed level depending on the
basic setting ( Y
page 220).
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.
Basic settings (excluding Mercedes-AMG
vehicles)

Important safety notes
G WARNING
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.
G WARNING
The vehicle is lowered if: R
you have selected the Comfort or Sport
suspension tuning and R
lock the vehicle after switching off the
engine
Persons in the vicinity of the wheel arch or the
underbody may thus become trapped. There
is a risk of injury.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you switch
off the engine.
! The vehicle is lowered by approximately
10 mm if: R
you have selected the Sport or Comfort
suspension tuning and R
you switch off the engine and then R
lock the vehicle
When parking, position your vehicle so that
it does not make contact with the curb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
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 ( Y
page 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.222

Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention can assist you during
parking. You may also use PARKTRONIC
( Y
page 224).
Important safety notes
Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park-
ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces Driving systems 227

arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv-
er's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the v
button on the multifunction steering wheel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) awa y from it .

Parking tips: R
The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In Driving system s 229
Dr ivi ng an d parking Z

some cases, it may also lead you across or
onto the curb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist. R
You can also select preselect transmission
position D . The vehicle redirects and does
not drive as far into the parking space.
Should the gear change occur too soon to
achieve a sensible parking position, the
parking procedure will be aborted.
Exiting a parking space In order that Active Parking Assist can sup-
port you when you exit the parking space: R
you need to have parked using Active Park-
ing Assist. R
the border of the parking space must be
high enough at the front and the rear. A
curb stone is too small, for example. R
the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvered into the park-
ing space. R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available. X

not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not func-
tion if: R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray R
there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet) R

or covered, for instance by a sticker, in the
vicinity of the camera R
there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work R
the lane markings are worn away, dark or
covered up, e.g. by dirt or snow R
the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected R
the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge R
the road is narrow and winding R
there are highly variable shade conditions
on the roadway R
no vehicle is detected in the adjacent lane
and there are broken lane markings
Warning vibration in the steering wheel
A warning may be given if a front wheel
passes over a lane marking. It will warn you by means of intermittent vibration in the steer-
ing wheel for up to 1.5 seconds.
In order that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly.
The warning vibration occurs earlier if: R
you approach the outer lane marking on a
bend. R
the road has very wide lanes, e.g. a high-
way. R
the system recognizes solid lane markings.
The warning vibration occurs later if: R
the road has narrow lanes. R
you cut the corner on a bend.
Lane-correcting brake application
G WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
G WARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate
brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk of
an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles.252
Driving systems
Driving and parking

If you leave your lane, under certain circum-
stances the vehicle will brake briefly on one
side. This is meant to assist you in bringing
the vehicle back to the original lane.
If a lane-correcting brake application occurs,
display C appears in the multifunction dis-
play.
A lane-correcting brake application can only
be made after driving over a solid, recogniz-
able lane marking. Before this, a warning
must be given by means of intermittent vibra-
tion in the steering wheel. In addition, a lane
with lane markings on both sides must be
recognized. The brake application also
slightly reduces vehicle speed.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if: R
you clearly and actively steer, brake or
accelerate. R
