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

City Safety

Driver Alert Control*

Road Sign Information*

Active main beam*

Park Assist*

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

workshop¹³²to 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.

NOTE

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 workshop¹³²to 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 workshop¹³²must 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

the vehicle ahead.

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.

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

NOTE

A bike carrier or other accessory mounted

on the rear of the car could obscure the

camera's view.

NOTE

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.

Defective camera

Rear parking camera

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.
