"Collision Warning with Auto Brake and Cyclist
and Pedestrian Detection" is an aid to assist the
driver when there is a risk of colliding with a
pedestrian, bicycle or vehicle in front that are
stationary or moving in the same direction.
The function uses the car's camera sensor,
which has certain limitations.
The car’s camera sensor is also used - as well as
by Collision Warning with Auto Brake - by the
functions:
•
•
Road sign information (p. 238)
•
Driver Alert Control - DAC (p. 243)
•
Keep the windscreen surface in front of the
camera sensor free from ice, snow, mist and
dirt.
Do not stick or attach anything to the wind-
screen in front of the camera sensor as this
may reduce effectiveness or cause one or
more of the systems dependent on the cam-
era to stop working.
The camera sensors have limitations similar to
the human eye, i.e. they "see" worse in darkness,
heavy snowfall or rain and in thick fog for exam-
ple. Under such conditions the functions of cam-
era-dependent systems could be significantly
reduced or temporarily disengaged.
Strong oncoming light, reflections in the carriage-
way, snow or ice on the road surface, dirty road
surfaces or unclear lane markings could also sig-
nificantly reduce camera sensor function when it
is used to scan the carriageway and detect
pedestrians and other vehicles.
The field of vision of the camera sensor is limited,
which is why pedestrians, cyclists and vehicles
cannot be detected in some situations, or they
are detected later than anticipated.
During very high temperatures the camera is
temporarily switched off for about 15 minutes
after the engine is started in order to protect
camera functionality.
Fault tracing and action
If the display shows the message
Windscreen
sensors blocked See manual
then this means
that the camera sensor is blocked and cannot
detect pedestrians, cyclists, vehicles or road
markings in front of the car.
At the same time, this means that - besides Colli-
sion Warning with Auto Brake - the following
functions will not have full functionality either:
•
Active main beam
•
Driver Alert Control
•
Lane Keeping Aid
•
Road sign information
The following table presents possible causes for
a message being shown along with the appropri-
ate action.
Cause
Action
The windscreen sur-
face in front of the
camera is dirty or cov-
ered with ice or snow.
Clean the windscreen
surface in front of the
camera from dirt, ice
and snow.
Thick fog, heavy rain
or snow means that
the camera does not
work sufficiently well.
No action. At times
the camera does not
work during heavy rain
or snowfall.
The windscreen sur-
face in front of the
camera has been
cleaned but the mes-
sage remains.
Wait. It may take sev-
eral minutes for the
camera to measure
the visibility.
Dirt has appeared
between the inside of
the windscreen and
the camera.
Visit a workshop to
have the windscreen
inside the camera
cover cleaned - an
authorised Volvo
workshop is recom-
mended.
