The camera in the rear area is protected by
means of a flap. This flap opens when the 360°
camera is activated. Observe the notes on
cleaning (
Ypage 310). For technical reasons,
the flap may remain open briefly after the 360°
camera has been deactivated.
The field of vision and other functions of the
camera system may be restricted due to addi-
tional attachments (e.g. license plate holder,
rear bicycle carrier).
On vehicles with height-adjustable chassis,
depending on technical conditions, leaving the
standard height can result in:
Rinaccuracies in the guide lines
Rinaccuracies in the display of generated
images (top view)

fo rthis reason ,traffic signs put up temporarily
(e.g. near roadworks) are no tdetected. There is
also no display fo rchangin gtraffic signs .
Traffic signs wit h arestriction indicated by an
additional sig n(e.g. in wet conditions) are also
shown .
Driving systems187

Page 190 of 370

The sign indicating the end of a restriction only
appears with the restriction in the instrument
cluster when:
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 avail-
able sources, no speed limit appears in the
instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, display :appears in the
assistance graphic (
Ypage 214).
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incorrect or out of date.
Instrument cluster display

XCall up the assistance graphic display func-
tion using the on-board computer

ment cluster.
Speed limit with unknown restriction
:Maximum permitted speed
;Maximum permitted speed for vehicles for
which the restriction in the additional sign is relevant
=Additional sign for unknown restriction
A maximum permitted speed of 80 mph
(80 km/h) and a speed limit of 60 mph
(60 km/h) with an unknown restriction apply.
The unit for the speed limit (km/h or mph)
depends on the country in which you are driving. It is generally neither shown on the traffic sign
nor on the instrument cluster but must be taken
into account when observing the maximum per-
mitted speed.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 188) and Lane Keeping
Assist (Ypage 190).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning lamp lights up in the exterior
mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical and
audible warning.
Blind Spot Assist supports you from a speed of
approximately 20 mph (30 km/h).
188Driving systems

Important safety notes
GWARNING
Blin dSpo t Assist does not react to:
Rvehicles overtaken too closely on the side,
plac ing them inthe blind spot area
Rvehicleswhic happr oach with a large speed
diff erential and overtake your veh icle
As a result, Blind Spot Assist may not give
warnings insuch situations. There isa risk of
an acc ident.
Always observe the traff icconditions care-
fully, and maintain a safe lateral distance.
Blin dSpo t Assist isonly anaid. It may fail to
detect some veh icles and isno substitute for
attentive driving. Always ensure that there is
suff icientdist ance to the sidefor other road
users and obstacles.
iUSA only:
This device has been approved bythe FCC as
a "Vehicular Radar System". The radar sensor
is intended for use inan automotive radar
system only. Removing, tampering with, or
altering the device willvoid any warranties,
and isnot permitted bythe FCC. Do not tam-
per with, alter, or use inany non- approved
way.
Any unauthorized mod ification to th isdevice
could void the user’s authority to operate the
equipm ent.
Radar sensors
The radar sensors for BlindSpo t Assist are inte-
grated into the rear bumper. Make sure that the bumpers are free from dirt, ice or slush. The
sensors must not becovered, for example by
cyc le
r
acks or overhanging loads. Fol lowing a
severe impact or inthe event of damage to the
bumpers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blin dSpo t Assist may no longer work properly.
Monitoring area
Inparticular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere ispoor vis ibility, e.g. due to fog, heavy
rain, snow or spray
Rthere are narrow vehicles, e.g. motorcycles or
bicycles
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middleof the lane
Rthere are barriers or other road boundaries
Vehicles inthe monitoring range are then not
indicated.
At a distance of around 1.6 ft (0.5m); from the
vehicle, Blind Spot Assist monitors the area up
to 10 ft (3 m)next to =and behind :your
vehicle, as shown in the picture.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles driving at the inner
edge of their lanes.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders
Rwarnings may be interrupted when driving
alongside long vehicles, such as trucks, for a
prolonged time

Warning lamp
:Warning lamp
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Blind Spot Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. The red warning lamp flashes on the
relevant exterior mirror. If the turn signal
remains on, detected vehicles are indicated by
the flashing of the red warning lamp on the exte-
rior mirror. There are no further warning tones.
Switching on Blind Spot Assist
XMake sure that Blind Spot Assist is activated
in the on-board computer (Ypage 216).
XTurn the SmartKey to position 2in the igni-
tion lock.
The red warning lamps on the exterior mirrors
light up until the engine is started.
Display in the assistance graphic
When Blind Spot Assist is activated, gray radar
waves propagating backwards appear next to
the vehicle in the assistance display in the mul-
tifunction display (
Ypage 214). Above a speed
of 20 mph (30 km/h), the color of the radar
waves in the assistance graphic changes to
green :. Blind Spot Assist is then ready for use.
Towing a trailer
When you attach a trailer, make sure you have
correctly established the electrical connection.
This can be accomplished by checking the trailer
lighting. In this event, Blind Spot Assist is deac-
tivated. The Blind
SpotAssistNotAvail‐able When Towing a Trailer See Opera‐tor's Manualmessage appears in the multi-
function display.
Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of multifunction cam-
era :which is attached behind the top of the
windshield. Active Lane Keeping Assist detects
lane markings on the road and can warn you
before you leave your lane unintentionally.
