Limitations for camera and radar
unit
The camera and radar unit has certain limita-
tions – which in turn also limit those func-
tions that use the unit. A driver should be
aware about the following examples of limita-
tions.
Driving support systems (p. 266)
•
The camera unit is used by several driver sup-
port systems and has the task of for example
detecting lane lines or traffic signs.
•
•
Location of the camera unit
The camera unit is used by the following func-
tions:
Adaptive cruise control*
Pilot Assist*
•
•
•
•
•
•

Lane assistance*
Steering assistance at risk of collision

about 15 minutes after the engine is started so
as to protect the unit's electronics. The cam-
era and radar unit restarts automatically when
the temperature has fallen sufficiently.
Before replacing a windscreen, contact a
workshop132 to verify that the correct
windscreen has been ordered and will be
fitted.
Common limitations for camera and
radar
•
•
•
Blocked unit
Damaged windscreen
The same type of windscreen wipers or
windscreen wipers approved by Volvo
must be fitted when the windscreen is
replaced.
If not rectified it can lead to reduced per-
formance for the driver support systems
that use the camera and radar unit. This
may result functions being reduced, being
switched off completely or giving incorrect
function responses.
When replacing the windscreen, the cam-
era and radar unit must be recalibrated by
a workshop132 to ensure the functionality
of all the camera and radar-based systems
in the car.
Further limitations for radar
The following is also applicable so as not to
risk incorrect function for the driver supports
that use the radar unit:
The marked area must be cleaned regularly and kept
free from stickers, objects, shade film, etc.
Vehicle speed
The radar unit's ability to detect a vehicle
ahead is greatly reduced if the speed of the
vehicle ahead is very different to the speed of
your own car.
The camera unit is placed inside the upper
section of the windscreen together with the
car's radar unit.
If a scratch, crack or stone chip appears
on the windscreen in front of any of the
"windows" for the camera and radar unit
and covers an area of
•
Do not place, stick or mount anything on the
inside or outside of the windscreen, in front of
or around the camera and radar unit – this
may interfere with camera and radar-based
functions. This may result functions being
reduced, being switched off completely or giv-
ing incorrect function responses.
approx. 0.5 × 3.0 mm (0.02 × 0.12 in.) or
more, a workshop132 must be contacted
so that the windscreen can be replaced.
Volvo recommends not repairing cracks,
scratches or stone chips in the area in
front of the camera and radar unit – the
entire windscreen should be replaced
instead.

High temperature
At very high temperatures the camera and
radar unit can temporarily be switched off for

dust storms and snow flurries. Under such
conditions, the functions of camera-depend-
ent systems could be significantly reduced or
temporarily disengaged.
Limited field of vision
The radar unit has a limited field of vision. In
some situations another vehicle is not
detected, or the detection is made later than
expected.
Small vehicles, such as motorcycles, or
vehicles not driving in the centre of the
lane can remain undetected.
Strong oncoming light, reflections in the car-
riageway, snow or ice on the road surface,
dirty road surfaces or unclear lane markings
can also significantly reduce camera function
when it is used to scan the carriageway to
detect pedestrians, cyclists, large animals and
other vehicles.
In bends, the radar unit may detect a dif-
ferent vehicle than intended or lose a
detected vehicle from view.
Low trailers
Low trailer in radar shadow
Low trailers can also be difficult for the radar
unit to detect, or are not detected at all - the
driver should therefore be particularly careful
when driving behind low trailers when the
adaptive cruise control* or Pilot Assist* is acti-
vated.
The radar unit's field of vision
Further limitations for camera
Sometimes the radar unit is late at detect-
ing vehicles at close distances - e.g. a
Impaired vision
The cameras have limitations similar to the
human eye, i.e. may "see" worse in for exam-

Because of this, the image may vary slightly in
brightness and quality. Poor light conditions
can result in reduced image quality.
Further limitations for Park assist
camera*
Recommended maintenance for
camera and radar unit
In order that the camera and radar units shall
function correctly, they must be kept clear of
dirt, ice and snow, and be cleaned regularly
with water and car shampoo.
Blind sectors
A bike carrier or other accessory mounted
on the rear of the car could obscure the
camera's view.
Dirt, ice and snow covering the sensors
may cause incorrect warning signals,
reduced or no function.

There are "blind" sectors between the cameras' fields

In the park assist camera's 360° view* obsta-
cles/objects may "vanish" in the gaps
between the individual cameras.
WARNING
Pay attention to the possibility that, even if
it only looks like a relatively small part of
the image is obscured, a relatively large
sector could be hidden from view. An
obstacle could thereby go undetected until
the car is very close to it.

Location of rear radar units. Keep the surface indi-
cated clean – on both the left and right-hand sides of
the car.
To ensure best possible functionality, the
surfaces in front of the sensors must be
kept clean.
•
Do not affix any objects, tape or labels in
the area of the sensors.
•
•
Clean camera lenses regularly with luke-
warm water and car shampoo - be careful
not to scratch the lenses.
Maintenance of driver support components
must only be performed at a workshop –
an authorised Volvo workshop is recom-
mended.

The following table presents examples of pos-
sible causes for a message being shown,
along with the appropriate action:
Symbols and messages for camera
and radar unit
Here are examples of some of the display
messages and symbols regarding the camera
and radar units that can be shown in the
driver display.
Detector blocked
If the driver display shows this sym-
bol and the message Windscreen
sensor Sensor blocked, see
Owner's manual, this means that
the camera and radar unit cannot detect other
vehicles, cyclists, pedestrians and large ani-
mals in front of the car, and that the car's
camera-based and radar-based functions may
be disrupted.
Cause
Action
The windscreen surface in front of the camera and radar unit is
dirty or covered with ice or snow.
Clean dirt, ice and snow from the windscreen surface in front of the camera
and radar unit.
Thick fog and heavy rain or snow block the radar signals or the
camera view.
No action. Sometimes the unit does not work during heavy rain or snowfall.
Water or snow from the road surface swirls up and blocks the
radar signals or camera view.
No action. Sometimes the unit does not work on a very wet or snow-covered
road surface.
Dirt has appeared between the inside of the windscreen and the
camera and radar unit.
Visit a workshop to have the windscreen inside the unit's cover cleaned - an
authorised Volvo workshop is recommended.
Strong oncoming light
No action. The camera unit is reset automatically in more favourable light con-
ditions.

WARNING
If a camera sector is black
and contains this symbol
then it means that the cam-
era is out of order.
Pay additional attention
while reversing when this
symbol is shown if a
trailer, bicycle rack or sim-
ilar is mounted and electri-
cally connected to the car.
The symbol indicates that
the parking assistance sensors rearward
are switched off and will not warn of any
obstacles.
