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.
Cruise control lever With the cruise control lever you can operate
Distronic Plus and variable Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:

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
i
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

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

Blind Spot Assist uses a radar sensor system
to monitor the area on both sides of your
vehicle. It supports you when you change
lanes at speeds above 30 km/h. In each case,
a warning lamp appears in the exterior mirror
as soon as a vehicle is detected in the area
monitored. When you switch on the corre-
sponding turn signal prior to changing lanes,
you receive an optical and acoustic collision
warning. Blind Spot Assist uses two sensors
in the front bumper and four sensors in the
rear bumper. G
Risk of accident
Blind Spot Assist is only an aid and may not
detect all vehicles. Blind Spot Assist does not
relieve you of the responsibility of paying
attention.
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.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
