Volvo XC90 Excellence (2018 year). Instruction

Do not place, stick or mount anything on the
outside or inside of the windscreen in front of
or around the camera and radar unit — this
can interfere with camera and radar-depend-
ent functions.

This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.

If the driver display shows this symbol
with the message "

Windscreen

sensor

Sensor blocked, see

Owner's manual

", it means that the

camera and radar unit cannot detect other vehi-
cles in front of the car.

The following table presents examples of possible causes for a message being shown, along with the appropriate action:

Cause

Action

The windscreen surface in front of the camera and radar unit is dirty or cov-
ered 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.

NOTE: The illustration is schematic - details may vary depending on car model.

Cause

Action

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.

NOTE

Keep the windscreen clean in front of the
camera and radar unit.

Vehicle speed

The capacity of the radar unit to detect vehicles
ahead is reduced significantly if:

•

the speed of the vehicle ahead is signifi-
cantly different from that of your own car

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.

The radar unit's field of vision.

Sometimes the radar unit is late at detecting
vehicles at close distances - e.g. a vehicle

that drives in between your car and the vehi-
cle ahead.
Small vehicles, such as motorcycles, or vehi-
cles not driving in the centre of the lane can
remain undetected.
In bends, the radar unit may detect the
wrong vehicle 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 driv-
ing behind low trailers when the adaptive cruise
control or Pilot Assist is activated.

High temperature

At very high temperatures the camera and radar
unit can temporarily be switched off for
about 15 minutes after the engine is started so
as to protect the unit's electronics. The camera
and radar unit restarts automatically when the
temperature has fallen sufficiently.

Damaged windscreen

IMPORTANT

If a crack, scratch or stone chip in the wind-
screen in front of one of the camera and
radar unit “windows” covers an area of
approx. 0.5 × 3.0 mm (0.02 × 0.12 in.) or
larger, a workshop must be contacted to have
the windscreen replaced – an authorised
Volvo workshop is recommended.

If not rectified it can lead to reduced perform-
ance for the driver support systems that use
the camera and radar unit.

This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.

To avoid the risk of failed, deficient or
reduced operation of driver support systems
that use the radar unit, the following also
applies:

•

Volvo recommends against repairing
cracks, scratches or stone chips in the
area in front of the camera and radar unit.
Instead, the whole windscreen should be
replaced.

•

Before replacing a windscreen, contact
an authorised Volvo workshop to verify
that the correct windscreen is ordered
and fitted.

•

The same type or Volvo-approved wind-
screen wipers must be fitted during
replacement.

IMPORTANT

When the windscreen is replaced, the camera
and radar unit must be recalibrated at the
workshop to ensure the functionality of all the
car’s camera and radar-based systems. An
authorised Volvo workshop is recommended.

Maintenance

In order that the camera and radar unit shall
function correctly, the windscreen in front of the
unit must be kept clear of dirt, ice and snow, and
be cleaned regularly with water and car shampoo.

NOTE

Dirt, ice and snow covering the camera and
radar unit will reduce its function and may
prevent measurement.

This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.

Limitations of the camera unit

The camera unit has certain limitations - which in
turn also limits those functions that use the unit.

Impaired vision

The camera has limitations similar to the human
eye, i.e. it can "see" worse in for example intense
snowfall or rain, dense fog, heavy dust storms
and snow flurries. Under such conditions, the
functions of camera-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 can also sig-
nificantly reduce camera function when it is used
to scan the carriageway to detect pedestrians,
cyclists, large animals and other vehicles.

Blocked unit

The marked area must be kept free from stickers,
objects, shade film, etc.

The camera unit is placed inside the upper sec-
tion of the windscreen together with the car's
radar unit.

IMPORTANT

Do not place, stick or mount anything on the
outside or inside of the windscreen in front of
or around the camera and radar unit — this
can interfere with camera and radar-depend-
ent functions.

This may mean that functions are reduced,
deactivated completely or give incorrect func-
tion response.

City Safety

City Safety uses visual, haptic and acoustic sig-
nals to alert the driver of any pedestrians,
cyclists, large animals and vehicles that appear.
The car then brakes automatically unless the
driver him/herself acts within a reasonable time.

Location of the radar unit

City Safety can prevent a collision or reduce colli-
sion speed.

City Safety is an aid to assist a driver who is at
risk of colliding with a pedestrian, large animal,
cyclist or a vehicle.

The City Safety function can help the driver to
avoid a collision when driving in queues, e.g.
when changes in the traffic ahead, combined with
a lapse in attention, could lead to an incident.

The function helps the driver by automatically
braking the car in the event of an imminent risk
of collision if the driver does not react in time by
braking and/or swerving.

City Safety activates a short, sharp braking proce-
dure, normally stopping the car just behind the
vehicle in front. For most drivers this is well out-
side normal driving style and may be perceived as
uncomfortable.

City Safety is activated in situations where the
driver should have started braking earlier, which
is why it cannot help the driver in every situation.

City Safety is designed to be activated as late as
possible in order to avoid unnecessary interven-
tion.

The driver or passengers are not normally aware
of City Safety - it only intervenes in a situation
where a collision is immediately imminent.

WARNING

•

The City Safety is supplementary driver
support intended to improve driving safety
– it cannot handle all situations in all traf-
fic, weather and road conditions.

•

The City Safety auto-brake function can
prevent a collision or reduce collision
speed, but to ensure full brake perform-
ance the driver should always depress the
brake pedal – even if the car auto-brakes.

•

The warning and steering assistance are
only activated if there is a high risk of col-
lision – you must therefore never wait for
a collision warning or for City Safety to
intervene.

•

The warning and brake intervention for
pedestrians and cyclists are deactivated
at vehicle speeds exceeding 70 km/h
(43 mph).

•

City Safety does not activate any auto-
brake functions in the event of heavy
acceleration.

•

City Safety is not a substitute for the driv-
er's attention and judgement. The driver
is always responsible for ensuring the car
is driven in a safe manner, at the appro-
priate speed, with an appropriate distance

NOTE: The illustration is schematic - details may vary depending on car model.

to other vehicles, and in accordance with
current traffic rules and regulations.

•

The driver is advised to read all sections
in the Owner's Manual that relate to City
Safety to learn about factors such as its
limitations and what the driver should be
aware of before using the system (see
the list of links at the end of this article).

Parameters for City Safety

City Safety can avoid a collision with a vehicle, a
cyclist, a pedestrian or a larger animal in front by
reducing the car's speed with the auto-brake
function.

If the speed difference is greater than the follow-
ing specified speeds, the City Safety auto-brake
function cannot prevent a collision but mitigates
the consequences of it.

Vehicles

For a vehicle in front, City Safety can reduce the
speed by up to 60 km/h (37 mph).

cyclists

For a cyclist, City Safety can reduce the speed by
up to 50 km/h (30 mph).

Pedestrians

For a pedestrian, City Safety can reduce speed by
up to 45 km/h (28 mph).

Large animals

In the event of a risk of a collision with a large
animal, City Safety can reduce the car's speed by
up to 15 km/h (9 mph).

The brake function for large animals is primarily
intended to reduce the force of the impact at
higher speeds and is most effective at speeds
above 70 km/h (43 mph) but less effective at
lower speed.

Overview

Function overview

Audio-visual warning signal in the event of a
collision risk
Distance measurement with the camera and
radar unit

City Safety carries out three steps in the follow-
ing order:

1. Collision warning
2. Brake support
3. Auto Brake
The following text explains what happens during
the three steps:

1 - Collision warning

The driver is first warned of a potentially immi-
nent collision.

City Safety can detect pedestrians, cyclists or
vehicles that are stationary or moving in the same
direction as the car and are ahead. City Safety
can also detect pedestrians, cyclists or large ani-
mals that are crossing the road in front of the car.

In the event of a risk of collision with a pedes-
trian, large animal, cyclist or vehicle (including
vehicles described in the "City Safety in cross
traffic" section), the driver's attention is alerted by
means of a red flashing warning signal, an acous-
tic signal and a haptic warning in the form of a
brake pulse. At lower speeds or with hard braking
or acceleration there will be no haptic warning.
The brake pulse frequency varies according to
the car's speed.
