object is marked with a bar. Objects located
some distance from the vehicle away are
marked with a yellow bar. If the distance to
the object is very small, the bar is displayed in
red.
Object detection only works in wide-angle
mode.
In order to use the function, it must be
switched on in Audio 20 or COMAND (see the
Digital Operator's Manual).
360° camera
General notes
The 360° camera is a system consisting of
four cameras.
The system analyzes images from the follow-
ing cameras:
RRear view camera
RFront camera
RTwo side cameras in the exterior mirrors
The cameras capture the immediate sur-
roundings of the vehicle. The system sup-
ports you, for example when parking or if
vision is restricted at an exit.
You can show pictures from the 360° camera
in full-screen mode or in six different split-
screen views on the Audio 20 or COMAND
display. A split-screen view also includes a
top view of the vehicle. This view is calculated
from the data supplied by the installed cam-
eras (virtual camera).
The six split-screen views are:
Rtop view and picture from the rear view
camera (130° viewing angle)
Rtop view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
Rtop view and enlarged rear view
Rtop view and enlarged front view
Rtop view and images from the rear-facing
side cameras (rear wheel view)
Rtop view and images from the forward-
facing side cameras (front wheel view) When the function is active and you shift the
transmission from
Dor Rto N, the guide lines
in the Audio 20 or COMAND display are hid-
den.
When you change between transmission
positions Dand R, you see the previously
selected front or rear view.
Distances measured by PARKTRONIC will
also be optically displayed:
Rin split screen view as red or yellow brack- ets around the vehicle icon in the top view,
or
Rat the bottom right as red or yellow brack-
ets around the vehicle symbol in full-screen
mode
The line thickness and color of the brackets
show how far the vehicle is from an object.
Ryellow brackets with thin lines:
PARKTRONIC is active
Ryellow brackets with normal lines: an
object is present in close range of the vehi- cle
Rred line: an object is present in the imme-
diate close range of the vehicle
Important safety notes
The 360°camera is only an aid and may show
a distorted view of obstacles, show them
incorrectly or not at all. The 360°camera is
not a substitute for attentive driving.
You are always responsible for safe maneu-
vering and parking. When maneuvering or
parking, make sure that there are no persons,
animals or objects in the area in which you are
maneuvering.
You are always responsible for safety, and
must always pay attention to your surround-
ings when parking and maneuvering. This
applies to the areas behind, in front of and
beside the vehicle. You could otherwise
endanger yourself and others.

When ATTENTION ASSIST is deactivated, the
ésymbol appears in the multifunction
display in the assistance graphic display.
When ATTENTION ASSIST has been deactiva-
ted, it is automatically reactivated after the
engine has been stopped. The sensitivity
selected corresponds to the last selection
activated (standard/sensitive).
Warning in the multifunction display
If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: ATTENTION ASSIST
Take a Break!.
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
XIf necessary, take a break.
XConfirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in concentra-
tion, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND. You can select a service station
and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum
speed permitted to the driver in the instru-
ment cluster. The data and general traffic reg-
ulations stored in the navigation system are
used to determine the current speed limit. Traffic Sign Assist is a map-based system,
and thus, traffic signs put up temporarily (e.g.
near roadworks) are not detected.
If a traffic sign that is relevant to your vehicle
is passed, the display of the speed limits is
updated.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are
also shown.
The traffic signs are only displayed with the
restrictions if:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the
available sources, no speed limit is displayed
in the instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, symbol :is shown in the
assistance graphic display (
Ypage 251).
Important safety notes
Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits.
Traffic signs always have priority over the
Traffic Sign Assist display.
The system may be either functionally
impaired or temporarily unavailable if the
information in the digital street map of the
navigation system is incorrect or out of date.
216Driving systems
Driving and parking

Rthe distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
Rthe lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
If no vehicle is detected in the adjacent lane
and broken lane markings are detected, no
lane-correcting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel
passes over a lane marking. It will warn you by
means of intermittent vibration in the steer-
ing wheel for up to 1.5 second s.
Lane -correcting brake application
If you leave your lane, under certain circum-
stances the vehicle will brake briefly on one
side. This is meant to assist you in bringing
the vehicle back to the original lane.
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
If a lane-correcting brake application occurs,
display :appears in the multifunction dis-
play. The brake application also slightly
reduces vehicle speed. This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can be
made after driving over a lane marking detec-
ted as being solid or broken. Before this, a
warning must be given by means of intermit-
tent vibration in the steering wheel. In addi-
tion, a lane with lane markings on both sides
must be recognized.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detec-
ted in the adjacent lane. Oncoming vehicles,
overtaking vehicles and vehicles in adjacent
lanes can be detected.
iA further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
Ryou clearly and actively steer, brake or
accelerate.
Ryou cut the corner on a sharp bend.
Ryou have switched on the turn signal.
Ra driving safety system intervenes, e.g.
ESP®, PRE-SAFE®Brake or Active Blind
Spot Assist.
Ryou have adopted a sporty driving style with
high cornering speeds or high rates of
acceleration.
RESP®is switched off.
Rthe transmission is not in position D.
Ra loss of tire pressure or a defective tire has
been detected and displayed.
Ran obstacle in the lane in which you are
driving has been detected .
Acti

ve Lane Keeping Assist may not detect
other road users or traffic situations. An inap-
propriate brake application may be interrup-
ted at any time if you:
Rsteer slightly in the opposite direction
Rswitch on the turn signal
Rclearly brake or accelerate
226Driving systems
Driving and parking

The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max-
imum permissible speed is. Observe the
legally prescribed maximum speed in the rel-
evant country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. Refer to the "Technical
data" section to find out whether this applies
to your vehicle.
If you utilize any of the added maximum rear
axle load when towing a trailer, the vehicle/
trailer combination may not exceed a maxi-
mum speed of 60 mph (100 km/h) for rea-
sons concerning the operating permit. This
also applies in countries in which the permis-
sible maximum speed for vehicle/trailer com-
binations is above 60 mph (100 km/h).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
Use the left-hand steering wheel paddle
shifter to shift into a lower gear in good time
on long and steep downhill gradients.
iThis also applies if you have activated
cruise control.
This will use the braking effect of the engine,
so that less braking will be required to main-
tain the speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you
need additional braking, depress the brake
pedal repeatedly rather than continuously.
Driving tips
RMaintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
RAvoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
RThe values given for gradient-climbing
capabilities from a standstill refer to sea level. When driving in mountainous areas,
note that the power output of the engine
and, consequently, the vehicle's gradient-
climbing capability, decreases with
increasing altitude.
If the trailer swings from side to side:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
Installing the ball coupling
GWARNING
If the ball coupling is not correctly installed
and secured, it can come loose during the
journey and endanger other road users. There is a risk of an accident and injury.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
GWARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
GWARNING
If the ball coupling is not installed and secured
correctly the trailer may come loose. There is
a risk of an accident.
Install and secure the ball coupling as descri-
bed in the ball coupling installation instruc-
tions. Make sure that the ball coupling is
installed and secured correctly before every
journey.
230Towing a trailer
Driving and parking

Observe the following when towing a trailer:
RTo gain driving experience and to become
accustomed to the new handling charac-
teristics, you should practice the following
in a traffic-free location:
-cornering
-stopping
-backing up
RBefore driving, check:
-trailer tow hitch
-safety switch for braked trailers
-safety chains
-electrical connections
-lights
-wheels
RAdjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
RIf the trailer has electronically controlled
brakes, pull away carefully. Brake manually
using the brake controller and check
whether the brakes function correctly.
RSecure any objects on the trailer to prevent
the cargo from slipping when the vehicle is
in motion.
RWhen you couple up a trailer, check at reg-
ular intervals that the load is firmly secured.
If the trailer is equipped with trailer lights
and brakes, check the trailer to ensure that
these are working.
RBear in mind that the handling will be less
stable when towing a trailer than when driv-
ing without one. Avoid sudden steering
movements.
RThe vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to side winds and
requires more careful steering.
RIf possible, do not brake suddenly, but
instead depress the brake pedal moder-
ately at first so that the trailer can activate its brakes. Then increase the pressure on
the brake pedal.
RIf the automatic transmission repeatedly
shifts between gears on uphill or downhill
gradients, shift to a lower gear using the
left-hand steering wheel paddle shifter.
A lower gear and lower speed reduce the
risk of engine failure.
RWhen driving downhill, shift to a lower gear
to utilize the engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
RIf the coolant temperature increases dra-
matically while the air-conditioning system is switched on, switch off the air-condition-
ing system.
Coolant heat can also be dissipated by
opening the windows and switching the
ventilation blower and the interior temper-
ature to the highest level.
RWhen overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of the vehicle/trailer
combination, you require addi

tional road
space in relation to the vehicle you are
overtaking before you can change back to
the original lane.
Decoupling a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
!Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound-
ing of the overrun brake.
