AIRMATIC package
General notes AIRMATIC is an air suspension system with var-
iable damping for improved driving comfort.
Level control ensures the best possible suspen-
sion and constant ground clearance, even with a
laden vehicle. When you drive fast, the vehicle is
lowered automatically to improve driving safety
and to reduce fuel consumption. There is also
the option to manually adjust the vehicle level.
AIRMATIC consists of: R
level settings R
level control and R
ADS or ADS PLUS (Adaptive Damping Sys-
tem)
All vehicles (except Mercedes-AMG vehi-
cles): your vehicle may also be equipped with
the ACTIVE CURVE SYSTEM ( Y
page 187).
Mercedes-AMG vehicles: your vehicle is equip-
ped with the ACTIVE CURVE SYSTEM
( Y
page 187).
Observe the notes on driving with a trailer
( Y
page 222).
The vehicle level can be set using the DYNAMIC
SELECT controller ( Y
page 145) or the level but-
ton ( Y
page 188). The setting always corre-
sponds to the last selected function. 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.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant 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. Low-
ering is interrupted if a door is opened, and it
continues once the door has been closed.
ADS and ADS PLUS (Adaptive Damping
System)
General notes The Adaptive Damping System automatically
controls the calibration of the dampers. The
damping characteristics adapt to the current
operating and driving situation.
The damping is tuned individually to each wheel
and depends on: R

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
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.
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 clear-
ance. You will otherwise damage the vehicle. R
Utility vehicles have a significantly higher roll-
over 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 sig-
nificantly more likely to die than a person
wearing a seat belt.
You and all vehicle occupants should always
wear your seat belts.
General notes Only select raised level if this is appropriate for
the road conditions. Otherwise, fuel consump-
tion may increase and handling may be affected.
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 possible.
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 discrep-
ancies while still parked. However, for signifi-
cant 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. Low-
ering is interrupted if a door is opened, and it
continues once the door has been closed.
Vehicles with no trailer coupled: below a
speed of 37 mph (60 km/h), you can choose
between the normal and raised vehicle level.
Sel ect the normal vehicle level for normal road
surfaces and the raised vehicle level for driving
with snow chains or on particularly poor road
surfaces. Your selection remains stored even if
you remove the SmartKey from the ignition lock.
If you try to select raised level at a speed above
37 mph (60 km/h), the Drive More Slowly

appears and a warning tone sounds. The vehicle
is now parked. The vehicle is kept stationary
without the driver having to depress the brake
pedal. The braking effect is canceled when you
depress the accelerator pedal.
Parking Pilot no longer supports you with steer-
ing interventions and brake applications. When
Parking Pilot is finished, you must steer and
brake again yourself. Parking Assist
PARKTRONIC is still available.
Parking tips: R
The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditions of the location. It
may be the case that Parking Pilot guides you
too far into a parking space, or not far enough
into it. In some cases, it may also lead you
across or onto the curb. If necessary, you
should cancel the parking procedure with
Parking Pilot. R
You can also select preselect transmission
position D . The vehicle redirects and does not
drive as far into the parking space. Should the
transmission change take place too early, the
parking procedure will be canceled. A sensi-
ble parking position can no longer be ach-
ieved from this position.
Exiting a parking space In order for Parking Pilot to assist you: R
the border of the parking space must be high
enough at the front and the rear. A curb 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 maneuvering into the parking
space. R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Parking Pilot can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel.
i If Parking Assist PARKTRONIC detects
obstacles, Parking Pilot brakes automatically
whilst the vehicle is exiting the parking space.
You are responsible for braking in good time. X

wheel is moved to the straight-ahead posi-
tion. X
Drive forwards and back up as prompted by
the Parking Assist PARKTRONIC warning dis-
plays, several times if necessary.
Once you have exited the parking space com-
pletely, the steering wheel is moved to the
straight-ahead position. You hear a tone and the
Parking Pilot Finished message appears in
the multifunction display. You will then have to
steer and merge into traffic on your own. Park-
ing Assist PARKTRONIC is still available. You can
take over the steering before the vehicle has
exited the parking space completely. This is
useful, for example when you recognize that it is
already possible to pull out of the parking space.196

ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways. It is
active in the 37 mph (60 km/h) to 125 mph
(200 km/h) range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid to the driver. It
might not always recognize fatigue or increasing
inattentiveness in time or fail to recognize them
at all. The system is not a substitute for a well-
rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occur at all: R
if the length of the journey is less than approx-
imately 30 minutes R
if the road condition is poor, e.g. if the surface
is uneven or if there are potholes R
if there is a strong side wind R
if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration R
if you are predominantly driving slower than
37 mph (60 km/ h) or faster than 125 mph
(200 km/ h)R
if you are driving with the Steering Pilot of
Distance Pilot DISTRONIC activated R
if the time has been set incorrectly R
in active driving situations, such as when you
change lanes or change your speed The attention level evaluation is deleted and
restarts when the journey is continued, if: R
you switch off the engine R
you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
Displaying the attention level
You can have current status information dis-
played in the assistance menu ( Y
page 236) of
the on-board computer. X
Select the Assistance display for ATTENTION
ASSIST using the on-board computer
( Y
page 237).
The following information is displayed: R
Length of the journey since the last break. R
the attention level determined by ATTENTION
ASSIST, displayed in a bar display in five levels
from high to low. R
If ATTENTION ASSIST is unable to calculate
the attention level and cannot output a warn-
ing, the System suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below
37 mph (60 km/h) or above 125 mph
(200 km/h).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer ( Y

Permissible trailer loads and drawbar
loads
Weight specifications
Maximum allowable gross mass The gross vehicle weight of the trailer is calcu-
lated by adding the weight of the trailer to the
weight of the load and equipment on the trailer.
You will find installing dimensions and loads
under "Technical data" ( Y
page 387).
Permissible noseweight
You will find installing dimensions and loads
under "Technical data" ( Y
page 387).
Loading a trailer R
When loading the trailer, make sure that nei-
ther the permissible gross weight of the trailer
nor the gross vehicle weight are exceeded.
The permissible gross vehicle weight is indi-
cated on the identification plate located on
the B-pillar on the driver's side of the vehicle.
You can find the maximum permissible values
on the type plates of your vehicle and the
trailer. When calculating how much weight the vehicle and trailer may carry, pay atten-
tion to the respective lowest values. R
The trailer drawbar load on the ball coupling
must be added to the rear axle load to avoid
exceeding the permissible gross axle weight.
The permissible gross vehicle weight is indi-
cated on the identification plate located on
the B-pillar on the driver's side of the vehicle.
i Mercedes-Benz recommends a trailer load
where the trailer drawbar noseweight
accounts for 8 % to 15 % of the trailer's per-
missible gross weight.
i The weight of additional accessories, pas-
sengers, and cargo reduces the permissible
trailer load and drawbar load for your vehicle.
Checking the vehicle and trailer weight R
To check that the weights of the towing vehi-
cle and the trailer comply with the maximum
permissible values, have the vehicle/trailer
combination (including the driver, passen-
gers, and cargo with a fully laden trailer)
weighed on a calibrated weighbridge. R
Check the gross axle weight rating of the front
and rear axles, the gross weight of the trailer
and the trailer drawbar noseweight.
