Road Engineering package)
Important safety notes Level control adapts the vehicle level automati-
cally to the current operating and driving situa-
tion. This results in reduced fuel consumption
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 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.

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. Driving systems

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 your driving style, e.g. sporty
R the road surface conditions
R the drive program selected
R the vehicle level setting
Selecting Comfort mode In the
Comfort drive program, the driving char-
acteristics of your vehicle are more comforta-
ble. Therefore, select this mode if you favor a
more comfortable driving style. Also select the
Comfort drive program when driving fast on
straight roads, e.g. on straight stretches of high-
way. X
Select the Comfortdrive program using
DYNAMIC SELECT controller 0043.

All vehicles (except Mercedes-AMG vehi-
cles): in theComfort drive program, the vehicle
is lowered by 0.6 in (15 mm) if you:
R drive at speeds above 70 mph (112 km/h) or
R drive at speeds between 60 mph (96 km/h)
and 70 mph (112 km/h) for longer than
20 seconds
The vehicle is raised again if you:
R drive at speeds below 25 mph (40 km/h) or
R drive at speeds between 25 mph (40 km/h)
and 40 mph (64 km/h) for longer than 20 sec- onds
Mercedes-AMG vehicles: in theComfort drive
program, the vehicle is:
R lowered by 0.4 in (10 mm) if you drive at
speeds above 112 mph (180 km/h)
R raised again if you drive at speeds below
87 mph (140 km/h)
Selecting Sport mode The firmer setting of the suspension tuning in
the Sport drive program ensures even better
contact with the road. Select this drive program when employing a sporty driving style, e.g. on
winding country roads.

Failure to operate this vehicle safely may
result in an accident, rollover of the vehicle,

R In a rollover crash, an unbelted person is sig-
nificantly more likely to die than a person

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.

WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open. G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occupants and luggage/cargo.
Do not exceed the load limit or permitted grossvehicle weight rating (GVWR) for your vehicle.
The gross load limit and the GVWR are specified
on the vehicle identification plate on the B-pillar
of the driver's door (Y page 361).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and rear
axles. The specifications for GVWR and GAWR are on the vehicle identification plate on the B-
pillar of the driver's door (Y
page 361).
Observe the notes on loading the vehicle
(Y page 361).
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a
load:
R Never exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
R The cargo compartment is the preferred place
to carry objects.
R Position heavy loads as far forward as possi-
ble and as low down in the cargo compart-
ment as possible.
R The load must not protrude above the upper
edge of the seat backrests.
R Always place the load against the rear or front
seat backrests. Make sure that the seat
backrests are securely locked into place.
R Always place the load behind unoccupied
seats if possible.
R Use the cargo tie-down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening mate-
rials appropriate for the weight and size of the load.
R Secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges for
protection. Stowage spaces
Important safety notes G
WARNING
If you transport objects in the vehicle interior and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction. Stowage areas
