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. Driving systems

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 219).
Due to the sportier suspension settings com- pared to standard vehicles, the levels and
speed thresholds for sinking and raising the
vehicle are different.
In Comfort and Sport driving modes, after
locking the vehicle it lowers to the Sport+
level. When locking the vehicle at the raised
level, the vehicle does not lower.
The settings will remain stored after you
switch off the engine. When starting the
engine, the selected setting, e.g. AMG adap-
tive suspension system Comfort, is restored.
i The vehicle level may change visibly if you
park the vehicle and the outside tempera-
ture changes. If the temperature drops, the vehicle level lowers; with an increase in
temperature, the vehicle level rises.
Suspension tuning General notes
The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.
The damping is tuned individually to each
wheel and depends on:
R your driving style
R the road surface conditions
R your individual selection of Sport, Sport +
or Comfort
Your selection remains stored even if you
remove the SmartKey from the ignition lock. Sport mode
The firmer suspension tuning in Sport mode
ensures even better contact with the road.
Select this mode when employing a sporty
driving style, e.g. on winding country roads.

Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park- ing space. When maneuvering, parking or
pulling out of a parking space, make sure thatthere are no persons, animals or objects in
the area in which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objects when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction. PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when you:
R switch on the ignition
R shift the transmission to position D,Ror N
R Release the electric parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/ h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper and four sensors in the rear bumper. 0043

Range of the sensors General notes
PARKTRONIC does not take objects into con-
sideration that are:
R below the detection range, e.g. people, ani-
mals or objects
R above the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps. Driving systems

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 225).
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. When maneu-
vering, parking or pulling out of a parking
space, make sure that there are no persons,
animals or objects in the area in which you are maneuvering. 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. 228
Driving systemsDriving and parking

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
Parking tips:
R On narrow roads, drive as close to the park-
ing space as possible.
R Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 226 )warning messages during the
parking procedure.
R At any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be canceled.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. G
WARNING
If there are objects above the detection range, Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Y page 225).
Active Parking Assist does not support you
with parking spaces parallel to the direction
of travel if:
R the parking space is on a curb
R the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
R the area is too small for the vehicle to
maneuver into
R the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer 0043
Detected parking space on the left
0044 Parking symbol
0087 Detected parking space on the right
Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle. Driving systems
229Driving and parking Z

Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 51 in (1.3 m) longer than
your vehicle
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a
status indicator in the instrument cluster.
When a parking space has been detected, an 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 0076
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) away from it.
