If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS (
Ypage 190).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front. The specified minimum distance is
set using the control on the cruise control
lever. When DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi-
tion
Pif:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, unless it is auto- matically switched off by the ECO start/
stop function.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
Ra system malfunction occurs.
Rthe power supply is not sufficient.
If a malfunction in the electric parking brake
occurs, then the transmission may also be
shifted into position Pautomatically.

AMG adaptive sport suspension sys-
tem
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:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection of Sport or Com-
fort mode.
The suspension setting is adjusted using the
corresponding button in the center console.
iThe mode can also be set using the AMG
DYNAMIC SELECT controller (
Ypage 158).
Each time you start the engine with the igni-
tion key or the Start/Stop button, Comfort
mode is activated. For further information
about starting the engine, see (
Ypage 151).
Sport mode
The firmer setting of the 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.

4MATIC
!
Never tow the vehicle with one axle
raised. This may damage the differential.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or be fully raised. Observe the instructions for
towing the vehicle with all wheels in full
contact with the ground.
4MATIC, together with ESP
®, improves the
traction of your vehicle whenever a drive
wheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con- ditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate less when driving.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
DSR
General notes
iDSR (Downhill Speed Regulation) is only
available for vehicles with the Off-Road
Engineering package. DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The
steeper the downhill gradient, the greater the
DSR braking effect on the vehicle. When driv-
ing on flat stretches of road or on an uphill
gradient, the DSR braking effect is minimal or
nonexistent.
DSR controls the vehicle’s speed when it is
activated and the transmission is in position
D
,R or N. You can drive at a higher or a lower
speed than that set on the on-board computer
at any time by accelerating or braking.
Important safety notes
GWARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ- ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor over-
ride the laws of physics. DSR cannot take
account of road, weather and traffic condi-
tions. DSR is only an aid. You are responsible
for the distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in your lane.
You are always responsible for keeping con-
trol of the vehicle and for assessing whether
the downhill gradient can be managed. DSR
may not always be able to keep to the set
speed, depending on road surface and tire
conditions. Select a set speed suitable for the
prevailing conditions and when necessary,
apply the brakes manually.

PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. PARKTRONIC 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 that
there 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.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
