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. 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, the
192Driving systems
Driving and parking

detected 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.
Important safety notes
GWARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations.
To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-
tion in the following or other similar situa-
tions:
Rwhen towing the vehicle
Rin the car wash
Deactivating the HOLD function
(

matically switched off by the ECO start/
stop function

RACE START (AMG vehicles)
Important safety notes
iRACE START must not be used on normal
roads. RACE START must only be activated and used on dedicated road circuits, out-
side of public road use.
iRACE START is only available in
Mercedes‑AMG vehicles.
GWARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP
®mode, there
is an increased risk of skidding and having an accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
RACE START enables optimal acceleration
from a standing start. For this, a suitably high-
grip road surface is required, along with the
tires and vehicle being in proper operating
condition.
iObserve the safety notes on driving safety
systems (
Ypage 65).
Be sure to read the safety notes and infor-
mation on ESP
®(Ypage 69).
Conditions for activation
You can activate RACE START if:
Rthe doors, hood and the trunk lid are
closed.
Rthe engine is running and the transmission,
all-wheel drive clutch and the engine are at operating temperature.
Rthe steering wheel is in the straight-ahead
position.
Rthe vehicle is stationary and the brake
pedal is depressed (left foot).
Rthe transmission is in position D.
Rdrive program S,S+ orRACE is selected
(

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.
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.

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.
