Limitations of Driver Alert Control

The Driver Alert Control (DAC) function may
have limitations in certain situations.

In some cases the system may issue a warn-
ing despite driving ability not deteriorating, for
example:

•

in strong side winds

•

on rutted road surfaces.

WARNING

In some cases, driving behaviour is not

affected despite driver fatigue – e.g. when

using the Pilot Assist

*

function – resulting

in the driver not getting a warning from

DAC.
It is therefore important to always stop and

take a break at the slightest feeling of fati-

gue, regardless of whether the function has

given a warning.

NOTE

This function uses the car's camera and
radar units, which have certain general lim-
itations.

Distance Warning

*

107

The Distance Warning function can assist the
driver to notice that the time interval to the
vehicle ahead may be too short. This requires
the car to be equipped with a head-up dis-
play

*

to be able to display Distance Warning.

Distance Warning symbol on the windscreen with

head-up display.

In cars equipped with head-up display, a sym-
bol is shown on the windscreen for as long as
the time interval to the vehicle ahead is shorter
than the preset value. However, this assumes
that the

Show Driver Support

function is

activated via the settings in the car's menu
system.

Distance warning is active at speeds
above 30 km/h (20 mph) and only reacts to

the vehicle ahead travelling in the same direc-
tion. No distance information is provided for
oncoming, slow or stationary vehicles.

NOTE

Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
screen difficult to recognise.

NOTE

Distance warning is deactivated during the
time the adaptive cruise control

*

or Pilot

Assist

*

is active.

WARNING

Distance warning only reacts if the time

window to the vehicle ahead is shorter

than the preset value – the speed of the

driver's vehicle is not affected.

Cross Traffic Alert

*

110

Cross Traffic Alert (CTA) is a driver support
that supplements BLIS

111

and is designed to

help the driver detect traffic crossing behind
the car when it is reversing.

The

auto-brake

subfunction can help the

driver to stop the car in the event of a risk of
collision with an unobserved vehicle.

Examples of areas where Cross Traffic Alert can

assist the driver to detect obstacles during reversing.

The function is primarily designed to detect
vehicles. In favourable conditions it may also
be able to detect smaller objects, such as
cyclists and pedestrians.

The function is only active if the car rolls back-
wards or if reverse gear has been selected.

If the function senses that something is
approaching from the side, this is indicated
with:

•

an acoustic signal - the sound is heard in
the left-hand or right-hand speaker
according to the direction from which the
object approaches.

•

an illuminated icon in the

Park Assist

System

graphic on the screen.

•

an icon on the Park assist camera top
view.

Illuminated icon for Cross Traffic Alert in the

Park

Assist System

graphic on the screen.

If the driver does not observe the warning
from the function and a collision is unavoida-
ble, the

auto-brake

function engages in order

to stop the car, after which the driver display
shows an explanatory text message on why
the car was braked.

WARNING

•

The function is supplementary driver
support intended to facilitate driving
and make it safer – it cannot handle all
situations in all traffic, weather and
road conditions.

The Cross Traffic Alert (CTA) function with

auto-brake

may have limited functionality in

certain situations. Brake intervention is active
at speeds below 15 km/h.

WARNING

The

auto-brake

subfunction can only

detect and brake for other vehicles that are

moving –

not

for stationary obstacles, a

cyclist or a pedestrian, for example.

The function has a certain limitation – the sen-
sors cannot "see" through other parked vehi-
cles or obstructions, for example.

Here are some examples of situations where
the function's "field of vision" may be already
limited and approaching vehicles cannot
therefore be detected until they are very close:

The car is parked deep inside a parking slot.

In an angled parking slot Cross Traffic Alert may be

completely “blind” on one side.

Blind sector.

Sector in which the function can
detect/"see".

However, as your car slowly reverses, the
angle it makes with the obstructing vehicle/
object changes and the blind sector rapidly
decreases.

Examples of further limitations

•

The

auto-brake

subfunction only detects

moving vehicles and therefore

cannot

"see" and brake for stationary obstacles, a
cyclist or a pedestrian, for example.

•

Dirt, ice and snow covering the sensors
may reduce the functions and deactivate
alerts.

•

CTA is automatically deactivated if a
trailer, bicycle rack or similar is connected
to the car's electrical system.

•

For good performance of CTA, there
should be no bicycle rack, luggage carrier
or similar mounted on the car's towbar.

NOTE

This function uses the car's radar units,
which have certain general limitations.

Park Assist

*

The Parking Assistance System (PAS

115

) uses

sensors to assist the driver when manoeu-
vring in tight spaces by indicating the dis-
tance to obstacles through acoustic signals
combined with a graphic in the centre dis-
play.

Screen view showing obstacle zones and sensor sec-

tors.

The centre display shows an overview of the
relationship between the car and detected
obstacles.

The highlighted sector indicates the location
of the obstacle. The closer the car symbol is to
a highlighted sector box at the front/back, the
shorter the distance between the car and
detected obstacle.

The side sectors change colour as the distance
between the car and an object is reduced.

The shorter the distance to the obstacle, the
faster the signal sounds. Other sound from the
audio system is muted automatically.

The acoustic signal for obstacles ahead and to
the sides is active when the car is moving but
stops after the car has been stationary for
approx. 2 seconds. The acoustic signal for
obstacles behind is also active when the car is
stationary.

At a distance within approx. 30 cm (1 ft) from
an obstacle behind or in front of the car, the
tone is constant and the active sensor field
closest to the car symbol is filled.

At a distance within approx. 25 cm (0.8 ft)
from an obstacle To the sides, the tone pulses
intensively and the active sector field changes
colour from ORANGE to RED.

The volume of the parking assistance signal
can be adjusted while the signal is sounding
by means of the [

>II

] knob on the centre con-

sole. Adjustment can also be performed in the
top view's

Settings

menu option.

NOTE

Except in the sector nearest to the car
symbol, audible warnings are only given for
objects directly in the path of the car.

) has dif-

ferent behaviour depending on which part of
the car is approaching an obstacle.

Forwards

The warning signal has a constant tone at less than

approx. 30 cm (1 ft) from an obstacle.

The Parking Assistance System's front detec-
tors are activated automatically when the
engine is started. They are active at speeds
below 10 km/h (6 mph).

The measuring range is approx. 80 cm (2.5 ft)
in front of the car.

NOTE

Parking assistance is deactivated when the
parking brake is used or

P

mode is

selected in a car with an automatic gear-
box.

IMPORTANT

When auxiliary lamps are fitted: Remember
that these must not obscure the sensors -
the auxiliary lamps may then be perceived
as an obstacle.

Backwards

The warning signal has a constant tone at less than

approx. 30 cm (1 ft) from an obstacle.

116

Park Assist System

DRIVER SUPPORT

* Option/accessory.

387

The sensors for reverse are activated if the car
rolls backward without a gear engaged or
when the gear lever is moved to reverse posi-
tion.

The measuring range is approx. 1.5 metres
(5 ft) behind the car.

When reversing with a trailer connected to the
car's electrical system, parking assistance
backward is deactivated automatically.

NOTE

When reversing with e.g. a trailer or bike
carrier on the towbar - without Volvo genu-
ine trailer wiring - parking assistance may
need to be switched off manually in order
that the sensors do not react to them.

Along the sides

The warning signal pulses intensively at less than

approx. 25 cm (0.8 ft) from an obstacle.

Parking assistance side sensors are activated
automatically when the engine is started. They
are active at speeds below 10 km/h (6 mph).

The measuring range is approx. 25 cm (0.8 ft)
from the sides.

However, the detection range of the side sen-
sors increases significantly when the steering
angle of the front wheels is increased, and
obstacles of up to approx. 90 cm (3 ft) located
diagonally behind or in front of the vehicle are
detected when the steering wheel is turned.

Limitations of Parking assistance

The Parking Assistance System (PAS

118

) can-

not detect everything in all situations and
may therefore have limited functionality in
some cases.

A driver should be aware about the following
examples of Park Assist Pilot's limitations:

WARNING

•

The parking sensors have blind spots
where obstacles cannot be detected.

•

Pay particular attention if there are
people and animals near the car.

•

Bear in mind that the front of the car
may swing out towards oncoming traf-
fic during the parking manoeuvre.

WARNING

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.

IMPORTANT

Objects e.g. chains, thin glossy poles or
low barriers may be in the "signal shadow"
and are then temporarily not detected by
the sensors - the pulsating tone may then
unexpectedly stop instead of changing
over to the expected constant tone.

The sensors cannot detect high objects,
such as projecting loading docks.

•

In such situations, pay extra attention
and manoeuvre/reposition the car par-
ticularly slowly or stop the current
parking manoeuvre - there may be a
high risk of damage to vehicles or
other objects since information from
the sensors is not always reliable in
such situations.

IMPORTANT

In certain conditions the parking assistance
system may produce incorrect warning
signals that are caused by external sound
sources with the same ultrasonic frequen-
cies that the system works with.

Examples of such sources include horns,
wet tyres on asphalt, pneumatic brakes,
exhaust noises from motorcycles, etc.

NOTE

Since a towbar is configured with the car's
electrical system, towbar protrusion is
included when the function measures the
distance to an object behind the car.

360° view

*

The "field of vision" of the parking cameras with

approximate coverage area.

The

360° view

function activates all parking

cameras, whereupon the four sides of the car
are shown simultaneously in the centre dis-
play, which helps the driver to observe what is
around the car when manoeuvring at slow
speeds.

From the 360° view, each camera view can
be activated separately:

•

Press the screen for the desired “field of
vision” of the camera, e.g. on the surface
in front of/above the front camera.

A camera symbol on the cen-
tre display's car symbol indi-
cates which of the cameras is
active.

If the car is also equipped
with

Park Assist System

*

then distance to detected obstacles is illus-
trated with fields in different colours.

The cameras can be activated automatically or
manually.

Backwards

The backwards-facing camera is fitted above the reg-

istration plate.

The backward-facing camera shows a wide
area behind the car. For certain models, part
of the bumper can be seen as well as the tow-
bar in some cases.

Objects shown in the centre display may
appear slightly tilted — this is normal.

Forwards

The forwards parking camera is located in the grille.

The front camera can be helpful on an exit
road with limited visibility to the sides, e.g.
when driving out of a garage. It is active at
speeds up to 25 km/h (16 mph) - following
which, the front camera is switched off.

If the car does not reach 50 km/h (30 mph)
and the speed falls below 22 km/h (14 mph)
within 1 minute after the forward-facing cam-
era has been extinguished, the camera is reac-
tivated.
