DISTRONI C PLUS
General notes DISTRONIC PLU S regulates th e speed and auto-
matically helps you maintain th e distanc e from
th e vehicle detecte d in front. Vehicles are detec -
te d wit h th e aid of th e radar sensor system.
DISTRONIC PLU S brake s automatically so that
th e set speed is no t exceeded.
Change into a lowe r gear in goo d time on lon g
and steep downhill gradients. Thi s is especially
important if th e vehicle is laden. By doin g so, you
will mak e use of th e braking effect of th e engine.
Thi s relieves th e load on th e brake syste m and
prevents th e brake s from overheatin g and wear -
in g to o quickly.
If DISTRONIC PLU S detects that there is a ris k of
a collision , you will be warned visually and
acoustically. DISTRONIC PLU S canno t preven t a
collision without your intervention . An intermit -
tent warnin g tone will then soun d and th e dis -
tanc e warnin g lamp will ligh t up in th e instru-
men t cluster. Brak e immediately in order to
increase th e distanc e to th e vehicle in fron t or
take evasiv e action provided it is saf e to do so.
DISTRONIC PLU S operates in th e speed range
between 0 mph (0 km/ h) an d 120 mph
(200 km/h).
Do not use DISTRONIC PLUS whil e driving on
roa ds with steep gradients.
As DISTRONIC PLUS transmits radar waves, it
can resemble the radar detectors of the respon-
sible authorities. You can refer to the relevant
chapter in the Operator's Manual if questions

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.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS.
G WARNING
DISTRONIC PLUS brakes your vehicle with up
to 50% of the maximum possible deceleration.
If this braking force is insufficient, DISTRONIC
PLUS warns you visually and audibly. There is
a risk of an accident.164
Driving systems
Driving and parking
Page 167 of 374

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
in 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 DISTRONIC 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 (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored.

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.
If these conditions are not present, Steering
Assist and Stop&Go Pilot cannot provide assis-
tance.
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 ai d. Y ou are responsible
fo
r maintaining a safe distance to the vehicle in
front, for vehicle speed, for braking in good time
and for staying in lane.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions and does not detect all road users. If
you 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 traffic pylons 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 system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
i llumination 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
work 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 highly variable shade conditions on
the roadway
The system is switched to passive and no longer
assists you by performing steering interventions
if: R
you actively change lane R
you switch on the turn signal R
you take your hands off the steering wheel or
do not steer for a prolonged period of time
Steering Assist and Stop&Go Pilot are activated
again automatically after a lane chang e is com-
p leted.
Steering Assist and Stop&Go Pilot do not pro-
vide any support: R
on very sharp corners R
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 164).
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 with170

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.

PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. Make sure that there are no persons,
animals or objects in the maneuvering area
while maneuvering and parking in/leaving park-
ing spaces.
! 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.
! Remove the detachable ball coupling if the
trailer tow hitch is not required. PARKTRONIC
measures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling.
PARKTRONIC is activated automatically when
you: R
switch on the ignition R
shift the transmission to position [ , ^ or
\\
PARKTRONIC is deactivated at speeds above
11 mph (18 km/ h) . It is reactivated at lower
speeds.
PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer.
Range of the sensors PARKTRONIC does not take objects into con-
sideration that are: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, for example over-
hanging loads, truck overhangs or loading
ramps. C
