2016 MERCEDES-BENZ C-CLASS CABRIOLET turn signal

Speed limit with unknown restriction
:
Maximum permissible speed
; Maximum permissible speed for vehicles for
which the restriction in the additional sign is
relevant
= Additional sign for unknown restriction
A maximum permissible speed of 80 km/h
(80 mph) and a speed limit of 60 km/h (60 mph) 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 on observance of the maximum
permissible speed.
No entry (wrong-way warning) A warning message
:is displayed on the
instrument cluster if Traffic Sign Assist detects
that you are passing a “no entry” sign and you
are driving in the wrong direction. You will then
also hear a warning tone. You should immedi-
ately check your direction of travel in order to
avoid danger to yourself and other road users. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 204) and Lane Keeping
Assist (Y page 206).
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 on the exterior
mirror and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible warning.
Blind Spot Assist supports you from a speed of
approximately 30 km/h.
Important safety notes G
WARNING
Blind Spot Assist does not react to vehicles:
R overtaken too closely on the side, placing
them in the blind spot area
R when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the side
of the vehicle.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is not a substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.
Radar sensors The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free of dirt, ice and slush. The sen- sors must not be covered, e.g. by cycle racks oroverhanging loads. Following a severe impact or in the event of damage to the bumpers, have the
function of the radar sensors checked at a quali- 204

fied specialist workshop. Blind Spot Assist may
no longer work properly in such cases.
Monitoring range In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their lane
R crash barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. At a distance of around 0.5 m
;from the vehi-
cle, Blind Spot Assist monitors the area up to
3.0 mnext 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 the vehicles are driving on the inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R warnings may be interrupted when driving
alongside long vehicles, e.g. lorries, for a pro-
longed time Warning lamp
:
Warning lamp
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above approx-
imately 30 km/h, warning lamp :on the cor-
responding side lights up red. This warning lamp always lights up when a vehicle enters the blindspot monitoring range from behind or from the
side. When you overtake a vehicle, the warning
occurs only if the difference in speed is less than
12 km/h.
If you select 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 blind spot moni-
toring range and you switch on the correspond-
ing 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 exterior mirror.
There are no further warning tones.

rior mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible warning. If a risk of side impact is detec-
ted, a course-corrective brake application may
help you avoid a collision. Active Blind Spot
Assist evaluates the free space in the direction
of travel and to the side before making a course- correcting brake application. For this, Active
Blind Spot Assist uses the forward-facing radar
sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated in the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The rear sen-
sors must not be covered, e.g. by bicycle 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. Active Blind Spot
Assist might otherwise no longer function prop-
erly. Monitoring range G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles. At a distance of approximately 0.5 m
;from
the vehicle, Active Blind Spot Assist monitors
the area up to 3.0 m next to =and behind :
your vehicle, as shown in the picture.
The detection of vehicles may be impaired in the
following situations:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may detect them too late.
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 vehicles are driving on the inner side of
their lane. 208
Driving systemsDriving and parking

R warnings may be issued in error when driving
close to crash barriers or similar solid boun-
daries
R warnings may be interrupted when you are
driving alongside particularly long vehicles,
such as lorries, for a prolonged time
Warning lamp :
Warning lamp
Active Blind Spot Assist is not operational at
speeds of below approximately 30 km/h. Vehi-
cles in the monitoring range are then not indi-
cated.
If a vehicle is detected within the blind spot
monitoring range at speeds of more than
approximately 30 km/h, warning lamp :on
the corresponding side lights up red. This warn-
ing lamp always lights up when a vehicle enters the blind spot monitoring range from behind or
from the side. When you overtake a vehicle, the
warning occurs only if the difference in speed is less than 12 km/h.
If you select the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings. When Active Blind Spot Assist is activated, grey
radar waves propagating rearwards appear next
to the vehicle on the assistant display on the
multifunction display. Above a speed of
30 km/h, the colour of the radar waves on the
assistant display changes to green ;. Active
Blind Spot Assist is then ready for use.
Visual and audible collision warning If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring range, you receive a visual and audible collision warning. You will then hear a double warning
tone and red warning lamp :flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-cor-
recting brake application is carried out. This is
designed to help you avoid a collision. G
WARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the sides.
If a course-correcting brake application occurs, red warning lamp :flashes on the exterior mir-
ror and a double warning tone sounds. In addi-
tion, a display underlining the danger of a side
collision appears on the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 30 km/h and
200 km/h. Driving systems
