Tips for driving with DISTRONIC PLUS
General notes
The following contains descriptions of certain
road and traffic conditions in which you must be particularly attentive. In such situations,
brake if necessary. DISTRONIC PLUS is then
deactivated.
Cornering, going into and coming out of a
bend
The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles traveling on a different line
DISTRONIC PLUS may not detect vehicles
traveling on a different line. The distance to
the vehicle in front will be too short.
186Driving systems
Driving an d parking

Other vehicles changing lanes
DISTRONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,
because of its narrow width. The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, thedetected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may detect vehicles that
are crossing your lane by mistake. Activating
DISTRONIC PLUS at traffic lights with cross-
ing traffic, for example, could cause your vehi-
cle to pull away unintentionally.
HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep
slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.

AMG adaptive sport suspension sys-
tem
General notes
The electronically controlled damping system works continuously. This improves driving
safety and ride comfort.
190Driving systems
Driving and parking

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 156).
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 149).
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.
XPress button :.
Indicator lamp ;lights up. You have selec-
ted Sport mode.
The AMG
SuspensionSystemSPORTmes-
sage appears in the multifunction display.
Comfort mode
In Comfort mode, the driving characteristics
of your vehicle are more comfortable. Select
this mode if you favor a more comfortable
driving style, but also when driving fast on
straight roads, e.g. highways.
XPress button :again so that indicator
lamp ;goes out.
You have selected Comfort mode.

message appears in the multifunction dis-
play.
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.

dampers. The damping characteristics adapt
to the current operating and driving situation.
The damping is tuned individually to each
wheel and depends on:
Ryour driving style, e.g. sporty
Rthe road surface conditions
Rthe drive program selected
Rthe vehicle level setting
The drive program can be set using the
DYNAMIC SELECT button (
Ypage 155).
Selecting Comfort mode
In the Comfort drive program, the driving
characteristics of your vehicle are more com-
fortable. Therefore, select this mode if you
favor a more comfortable driving style. Also
select the Comfortdrive program when driv-
ing fast on straight roads, e.g. on straight
stretches of highway.
XPress DYNAMIC SELECT button :
(
Ypage 155) as many times as necessary
until the Comfort drive program is selec-
ted.
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 pro-
gram when employing a sporty driving style,
e.g. on winding country roads.

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.
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:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rrelease the electric parking brake
Range of the sensors
General notes
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps.

:Sensors in the front bumper, left-hand

The sensors must be free from dirt, ice or
slush. They can otherwise not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(
Ypage 305).
