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.
Indicate d temperatures jus t abov e th e freezing
poin t do no t guarantee that th e roa d surfac e is
free of ice . The roa d may s till be icy, especially in
w ooded area s or on bridges .
You should pay special attention to roa d condi-
tion s when temperatures are around freezing
point.

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
If there is a chang e of drivers, advise th e ne w
driver of th e speed stored.Driving systems 169

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.
