G
Risk of accident
Distronic Plus cannot take account of road
and traffic conditions. If Distronic does not
recognise or no longer recognises the vehicle
in front, do not activate Distronic or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at roadworks on a
motorway
Otherwise, Distronic Plus maintains the cur-
rent speed or accelerates up to the set speed.
Distronic Plus cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic Plus:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when Distronic Plus is activated. Other-
wise, you may fail to recognise dangers in
time, could cause an accident and injure your-
self and others.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. Further information
can be found in the index under "Radar
sensor system".
Vehicles with COMAND and navigation sys-
tem*: you must deactivate the radar sensor
system near radio telescope facilities
(Y page 411). If you want Distronic Plus to assist you, the
radar sensor system must be activated and
operational.
If no car is driving in front of you, Distronic
Plus works like cruise control in the speed
range between 30 km/h and 200 km/h. If a
vehicle is driving in front of you, Distronic Plus
works in the speed range between 0 km/h
and 200 km/h.
Do not use Distronic Plus while driving on
roads with steep gradients.
G
Risk of accident
Distronic Plus brakes your vehicle at a maxi-
mum of 4m/s2
depending on its speed. This
corresponds to approximately 40% of your
vehicle's maximum brake force. You must
also apply the brakes yourself if this braking
power is not sufficient.
If Distronic Plus detects a risk of collision with
a vehicle in front, an intermittent warning tone
sounds. In addition, the ·distance warn-
ing lamp in the instrument cluster lights up.
Brake to avoid a collision.

erate briefly to overtake, Distronic Plus
adjusts the vehicle's speed to the last
speed stored after you have finished over-
taking.
Distronic Plus is automatically deactivated if:
R you engage the electric parking brake or if
the vehicle is automatically secured with
the electric parking brake
R you are driving slower than 25 km/h and
there is no vehicle in front, or the vehicle in
front is no longer detected

a warning tone. You will see the DISTRONIC
PLUS off message in the multi-function dis-
play for approximately five seconds
Tips for driving with Distronic Plus 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.

If you want Park Assist to assist you, the radar
sensor system must be activated and opera-
tional.
Park Assist is an electronic parking aid with
radar sensors. It assists you when parking by
displaying the distance between your vehicle
and an obstacle, and by emitting a warning
tone when you approach an obstacle.
Park Assist is automatically activated when
you shift the automatic transmission to D,R
or Nwhile the engine is running.
Park Assist is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Park Assist is also deactivated when you shift
the automatic transmission to Por switch off
the engine.
Park Assist is deactivated when the transmis-
sion is in position Nif you use the electric
parking brake to secure the vehicle.
Park Assist monitors the area around your
vehicle using four sensors in the front bumper
and two sensors in the rear bumper.
Range of the sensors Side view Top view

As the sensors have a wide detection
range, Park Assist may detect and warn you
about the following obstacles:
R Obstacles on the ground, such as man-
hole covers, rails, holes in the road or
drains
R Obstacles that move upwards quickly,
such as roller doors

as low walls around flower beds, high cross-
bars or trailer towbars. Park Assist does not
detect such objects when they are in the
immediate vicinity of the vehicle. You could
damage the vehicle or the objects.
i The Park Assist sensors are built into the
front and rear bumpers. Make sure that the
bumpers are free from dirt, ice or slush in 252

Parking Guidance*
Parking Guidance is an electronic parking aid
with radar sensors. The radar sensors are
used to measure the road on both sides of the
vehicle. It indicates suitable parking spaces
and provides steering instructions to help you
park in the indicated spaces. G
Risk of accident
Parking Guidance is only an aid. Parking
spaces detected may not be suitable for park-
ing due to, for example, parking prohibitions,
driveways, or unsuitable surfaces, etc.
The Parking Guidance display in the instru-
ment cluster is only a symbolic display of the
parking space as measured when first driving
past it. Later changes to the parking space are
not taken into account, e.g. if the vehicle
parked in front of or behind the space has
changed its position, or if obstacles are
moved into the parking space. Moving
objects, such as pedestrians and passing
vehicles, are not displayed.
Parking Guidance does not relieve you of the
responsibility to pay attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. Further information
can be found in the index under "Radar
sensor system".
Vehicles with COMAND and navigation sys-
tem*: the radar sensor system is automati-
cally deactivated near radio telescope facili-
ties (Y page 411). If you want Parking Guidance to assist you,
the radar sensor system must be activated
and operational.
Use Parking Guidance for parking spaces:
R
that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat kerbs.
Parking tips:
R on narrow roads, drive as close to the park-
ing space as possible.
R parking spaces which are littered, over-
grown or in front of trailers might not be
identified properly.
R pay attention to the Park Assist warning
messages when using Parking Guidance
(Y page 251).
R The position of your vehicle in the parking
space after using Parking Guidance
depends on the position and shape of the
vehicles parked in front and behind, and on
the conditions of the space. In some cases,
Parking Guidance may guide you too far
into a parking space, or not far enough into
it. In this case, you should cancel Parking
Guidance and correct the vehicle's posi-
tion.
Detecting parking spaces Parking Guidance is automatically activated
when you drive forwards. The system is
operational at speeds of up to approximately
40 km/h. While in operation, the system inde-
pendently locates and measures existing
parking spaces to both sides of the vehicle.
When driving at speeds below 16 km/h, you
will see the white parking space symbol as a
status indicator in the instrument cluster. If a
parking space is detected, the parking space
symbol changes colour to blue.254

For Blind Spot Assist to help you when driving,
the radar sensor system must be switched on
and operational. G
Risk of accident
Blind Spot Assist cannot detect road and traf-
fic conditions.
Blind Spot Assist may not detect narrow vehi-
cles, such as motorcycles or bicycles, or only
detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others.
Monitoring range of the sensors Blind Spot Assist monitors the area up to
three metres behind your vehicle and directly
next to your vehicle as shown in the diagram. G
Risk of accident
Blind Spot Assist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past at high speeds are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in a staggered formation in
different lanes. This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest away from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others.
If the lanes are narrow, the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especially if the vehicles are driving in a stag-
gered formation in different lanes. This may
be the case if vehicles are driving at the edge
of the lane that is nearest your vehicle.
The Blind Spot Assist sensors are integrated
into the front and rear bumpers. Make sure
that the bumpers are free from dirt, ice or
slush around the sensors. The radar sensors
must not be covered, for example by cycle
racks or overhanging loads. Following a
severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre. Otherwise, Blind Spot Assist may not
work properly. Driving systems
