G DANGER
If th e exhaust pipe is blocke d or adequate
ventilation is no t possible, poisonous gase s
suc h as carbon monoxide (CO) may ente r th e
vehicle. This is th e case, e.g. if th e vehicl e
become s trapped in snow. There is a ris k of
fatal injury.
If you leav e th e engin e or th e auxiliary heating
running, mak e sur e th e exhaust pipe and area
around th e vehicl e are clear of snow. To
ensur e an adequate supply of fresh air, open a
window on th e side of th e vehicl e that is no t
facing int o th e wind.
Hav e your vehicl e winter-proofe d at a qualified
specialist workshop at th e onset of winter.
Drive particularly carefully on slipper y roa d sur -
faces. Avoid sudden acceleration , steering and
braking maneuvers . Do no t use th e cruise con-
trol or DISTRONI C PLUS.
If th e vehicl e threaten s to skid or canno t be
stoppe d when moving at low speed:X
Shift th e transmission to position N .
The outside temperature indicator is no t
designed to serve as an ice-warning device and
is therefor e unsuitable for that purpose .
Changes in th e outside temperature are dis-
played after a short delay.

Cruise cont rol
Gene ra l notesCruis e control maintains a constan t roa d speed
for you. It brakes automatically in order to avoid
exceedin g th e set speed. Change int o a lower
gear in goo d time on lon g and steep downhill
gradients . This is especially important if th e
vehicl e is laden . By doin g so, you will mak e use
of th e braking effec t of th e engine. This relieves
th e load on th e brak e system and prevents th e
brakes from overheating and wearing to o
quickly.
You can use cruise control if you wan t to drive at
a steady speed for a prolonged period of time.
You can store any roa d speed abov e 20 mph
(30 km/h).
Import ant safety notesIf you fail to adapt your drivin g style, cruise con-
trol can neither reduce th e ris k of an acciden t
no r override th e laws of physics . Cruis e control
canno t tak e int o accoun t th e road, traffic and
weather conditions. Cruis e control is only an
aid. You are responsibl e for maintainin g a saf e
distanc e to th e vehicl e in front, for vehicl e
speed, for braking in goo d time and for stayin g in
lane.
Do no t use cruise control :R
in roa d and traffic condition s whic h do no t
allow you to maintai n a constan t speed, e.g. in
heav y traffic or on windin g roadsR
on slipper y roa d surfaces. Braking or accel-
erating could caus e th e drive wheels to lose
traction and th e vehicl e could then skidR
when there is poor visibility, e.g. due to fog ,
heav y rain or snow

DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance from
the vehicle detected in front. Vehicles are detec-
ted with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear-
ing too quickly.
If DISTRONIC PLUS detects that there is a risk of
a collision, you will be warned visually and
acoustically. DISTRONIC PLUS cannot prevent a
collision without your intervention. An intermit-
tent warning tone will then sound and the dis-
tance warning lamp will light up in the instru-
ment cluster. Brake immediately in order to
increase the distance to the vehicle in front or
take evasive action provided it is safe to do so.
DISTRONIC PLUS operates in the speed range
between 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTR ONIC P LUS transmits radar waves, it
ca
n resemble the radar detectors of the respon-
sible authorities. You can refer to the relevant
chapter in the Operator's Manual if questions
are asked about this.

Important safety notes
G WARNING
DISTRONIC PLUS does not react to: R
people or animals R
stationary obstacles on the road, e.g. stop-
ped or parked vehicles R
oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
G WARNING
DISTRONIC PLUS cannot always clearly iden-
tify other road users and complex traffic sit-
uations.
In such cases, DISTRONIC PLUS may: R
give an unnecessary warning and then
brake the vehicle R
neither give a warning nor intervene R
accelerate or brake unexpectedly
There is a risk of an accident.Driving system s 171
Dr ivi ng an d parking Z

Continue to driv e carefully and be ready to
brake, in particular when warned to do so by
DI ST RONIC PLU S.
G WAR NING
DI ST RONIC PLUS brakes your veh icle wit h up
to 50 %o f the maximum possible deceleration.
If this braking force is insufficient, DISTRONIC
PLUS warns you visually and audibly. There is
a risk of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat-
ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations: R
when towing the vehicle R
in the car wash
DISTRONIC PLUS can neither reduce the risk of
an accident if you fail to adapt your driving style
nor override the laws of physics. DISTRONIC
PLUS cannot take account of road, weather and
traffic conditions. DISTRONIC PLUS is only an
aid. You are responsible for maintaining a safe
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
Do not use DISTRONIC PLUS: R
in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line.
In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is snow or heavy rain R
there is interference by other radar sources R
there are strong radar reflections, for exam-
ple, in parking garages
If DISTR ONIC PLUS no longer detects a vehicle
in front, DISTRONIC PLUS may unexpectedly
accelerate the vehicle to the stored speed.
This speed may: R
be too high if you are driving in a filter lane or
an exit lane R
be so high in the right lane that you pass vehi-
cles driving on the left (left-hand drive coun-
tries) R
be so high in the left lane that you pass vehi-
cles driving on the right (right-hand drive
countries)
If there is a change of drivers, advise the new
driver of the speed stored.

gram, the vehicle accelerates more gently. This
setting is recommended in stop-and-start traf-
fic.
Mercedes-AMG vehicles: DISTRONIC PLUS
supports a sporty driving style when you select
the S or M drive program ( Y
page 155). Accel-
eration behind the vehicle in front or to the set
speed is then noticeably more dynamic. When
you select the C drive program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-and-start traffic.
Changing lanes DISTRONIC PLUS aids you when switching to
the overtaking lane, if: R
you are driving faster than 45 mph (70 km/h) R
you switch on the appropriate turn signal R
DISTRONIC PLUS does not detect a danger of
a collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
When you change lanes, DISTRONIC PLUS mon-
itors the left lane (on left-hand-drive vehicles) or
the right lane (on right-hand-drive vehicles).
Stopping
G WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle. R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. R
the battery is disconnected. R
the 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 ( Y
page 176).
If DISTRONIC PLUS detects that the vehicle in
front has stopped, it will cause your vehicle to
brake and come to a halt.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient 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 trans-
mission is shifted automatically to position P if:R
the driver's seat belt is not fastened and the
driver's door is open. R
the 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: R
a system malfunction occurs. R
the power supply is not sufficient.
If a malfunction occurs, the transmission may
also shift into position P automatically.

taking.
Setting a specified minimum distance You can set the specified minimum distance for
DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS maintains to the vehicle in
front, depending on the driving speed. You can
see this distance in the multifunction display
( Y
page 175).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.

DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot helps you keep the vehicle in the
center of the lane by means of moderate steer-
ing interventions in a speed range from
0–125 mph (0–200 km/h).
It monitors the area in front of your vehicle by
means of multifunction camera C , at the top of
the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
Stop&Go Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when
you are following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Steering Assist focuses on clear lane markings
(left and right), only focusing on the vehicle in
front if clear lane markings are not present.
Steering Assist and Stop&Go Pilot do not pro-
vide any support if these conditions do not exist.
DISTRONIC PLUS must be active in order for the
function to be available.
Important safety notes
If you fail to adapt your driving style, DISTRONIC
PLUS with Steering Assist and Stop&Go Pilot
can neither reduce the risk of an accident nor
override the laws of physics. It cannot take
account of road, weather and traffic conditions.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot is only an aid. You are responsible
for the distance to the vehicle in front, for vehi- cle speed, for braking in good time and for stay-
ing in your lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and d oes not detect all road users. If
y ou are following a vehicle which is driving
towards the edge of the road, your vehicle could
come into contact with the curb or other road
boundaries. Be particularly aware of other road
users, e.g. cyclists, that are directly next to your
vehicle.
Obstacles such as building site huts on the lane
or projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the
opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, steering inter-
vention is not sufficient to bring the vehicle back
to the lane. In such cases, you must steer the
vehicle yourself to ensure that it does not leave
the lane.
The support provided by the system can be
impaired if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
w o rk R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are strong shadows cast on the roadDriving systems 177

when a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS ( Y
page 171).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Assist
and Stop&Go Pilot are switched to passive.
