2017 MERCEDES-BENZ C-Class COUPE ESP

The detection of obstacles can be impaired in
the case of:
Rthere is dirt on the sensors or anything else
coveringthe sensors
Rpoor 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 only 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 there are vehicles at the inner edge of
your lane.
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 particularly long vehicles, e.g.
trucks, for aprolonged time.
Warning display
:Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 20 mph (30 km/h).
Vehicles in the monitoring range are then not
indicated.
If av ehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(3 0k m/ h),w arnin glamp :on the correspond-
ing side lights up red. This warnin gisalways
emitted when avehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake avehicle, the warnin gonly
occurs if the differenc einspeed is less than
7m ph (12 km/h). If you select the reverse gear, Active Blind Spot
Assis
tisnot operational.
The brightness of the warnin glamps is auto-
matically adapted to the brightness of the sur-
roundings.
When Active Blind Spot Assis tisactivated, gray
radar waves propagatin gbackwards appear
nex ttot he vehicle in the assistance display in
the multifunction display. Abov easpeed of
20 mph (30 km/h), the color of the radar waves
in the assistance display changes to green ;.
Active Blind Spot Assis tisthen ready for use.
Visua land acoustic collision warning
If you switc honthe turn signals to change lanes
and avehicle is detected in the side monitoring
range, you receiv eavisual and acoustic collision
warning. You will then hear adouble warning
ton eand red warnin glamp :flashes. If the turn
signal remainso n, detected vehicles are indica-
ted by the flashingofr ed warninglamp :.
There are no further warnin gtones.
Course-correcting brake application
If Active Blind Spot Assis tdetects arisk of alat-
eral collision in the monitoring range, acourse-
correcting brake application is carried out. This
is meant to assist you in avoiding acollision.
GWARNING
Ac ourse-correctin gbrake application cannot
always preventac ollision.There is arisk of an
accident.
Always steer ,brake or accelerate yourself,
especially if Active Blind Spot Assis twarns

Ifac ourse-correcting brake application occurs,
red warning lamp :flashe sinthe exterior mir-
ror and adualw arning tone sounds. In addition,
display ;underlining the danger of aside col-
lision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. Acourse-cor-
recting brake application may be interrupted at
any time if you steer slightly in the opposite
direction or accelerate.
The course-correcting brake application is avail-
abl eint he speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).
Either no braking application, or acourse-cor-
recting brake application adapted to the driving
situation occurs if:
Rthere are vehiclesoro bstacles,e.g. crash
barriers, located on both sides of you rvehicle.
Rav ehicle approaches you too closely at the
side.
Ryou have adopted asporty driving style with
high cornering speeds.
Ryou clearl ybrake or accelerate.

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area in
front of you rvehicle by means of multifunction
camera :at the top of the windshield. Various
different area stothe front, rear and side of your
vehicle are also monitored with the aid of the
rada rsensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave you rlane unin-
tentionally .Ifyou do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the originall ane.
Important safety notes
If you fail to adapt yourdriving style, Active Lane
Keeping Assist can neither reduce the risk of
accident nor override the law sofphysics. Active
Lane Keeping Assist cannot take account of
road and weather conditions. It may not recog-
nize traffic situations. Active Lane Keeping
Assist is only an aid .You are responsible for the
distance to the vehicle in front, for vehicle
speed,f or braking in good time and for staying in
you rlane.
Active Lane Keeping Assist cannot continuously
keep you rvehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearl ydetect lane markings.
In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make acourse-correcting brake application
to the vehicle
Rnot give awarning or intervene
There is arisk of an accident.
