Driver Alert Control limitations

Driver Alert Control (DAC) functionality may
be reduced in certain situations.

In certain situations, the system may provide a
warning even if it has not detected a change in
driving behavior, e.g.:

•

in strong crosswinds

•

on grooved road surfaces.

WARNING

In certain cases, driving behavior might not

be affected despite the driver's fatigue –

when using the Pilot Assist

function –

resulting in the driver not getting a warning

from DAC.
It is therefore very important to always

stop and take a break at the slightest sign

of fatigue, regardless of whether the func-

tion has issued a warning or not.

Driver Alert Control (p. 329)

The function uses the vehicle's camera and
radar sensor, which has certain general
limitations.

Cross Traffic Alert

Cross Traffic Alert(CTA) is a supplementary
driver support system to BLIS

that is

intended to help the driver detect vehicles
crossing behind the vehicle while backing up.

The

auto-brake

subfunction can help the

driver stop the car if there is a risk of collision
with an unobserved vehicle.

Examples of areas in which Cross Traffic Alert can

help the driver detect obstacles while backing up.

The function is primarily designed to detect
vehicles, but in certain cases can also detect
pedestrians or smaller objects such as bicy-
cles.

The function is only active when the vehicle is
moving backward or reverse gear is engaged.

If the function detects that something is
approaching your vehicle from the side:

•

an audible signal will sound from either
the left or right speaker, depending on
which side of your vehicle the object is
approaching from.

•

an icon will illuminate in the

Park Assist

System

graphic on the screen.

•

an icon will appear in the Park Assist Cam-
era's Top view.

Illuminated Cross Traffic Alert icon in the

Park

Assist System

graphic on the screen.

If the driver does not pay attention to the
warning from the function and a collision is
unavoidable, the

auto brake

function will

intervene to stop the vehicle and a text will be

Warning for crossing traffic when the vehicle is backing up.

Cross Traffic Alert

limitations

The Cross Traffic Alert (CTA) function with

auto brake

may have limited functionality in

certain situations. Auto-brake is active at
speeds under 15 km/h (9.3 mph).

WARNING

The

auto-brake

sub-function can only

detect and apply the brakes for other mov-

ing vehicles –

not

for e.g. stationary obsta-

cles, cyclists or pedestrians.

The function has certain limitations – the sen-
sors, for example, cannot "see" through other
parked vehicles or objects blocking the vehi-
cle.

Below are a few examples of situations in
which the function's field of vision may be ini-
tially limited and approaching vehicles may
therefore not be detected until they are very
close to your vehicle:

The vehicle is parked very far into a parking space.

In a diagonal parking space, Cross Traffic Alert may

be completely "blind" on one side of your vehicle.

Blind zone.

The function's field of vision.

However, as you back your vehicle slowly out
of a parking space, CTA's field of vision
changes in relation to the obstructing vehicle/
object and its blind zone is reduced.

Examples of further limitations

•

The

auto brake

subfunction only detects

vehicles in motion and may therefore

not

"see" and brake for e.g. stationary obsta-
cles, a cyclists or a pedestrian.

•

Dirt, ice and snow covering the sensors
may reduce functionality and prevent the
system from providing warnings.

•

CTA is automatically deactivated if a
trailer, bicycle holder or similar is con-
nected to the vehicle's electrical system.

•

For CTA to function effectively, bicycle
holders, luggage racks or similar should
not be mounted on the vehicle's towbar.

The function uses the vehicle's radar sen-
sors, which have certain general limita-
tions.

Park Assist

The Park Assist function (PAS

) uses sen-

sors to help the driver when maneuvering in
tight spaces by indicating distances to obsta-
cles using audible signals and graphics in the
center display.

Display view showing obstacle zones and sensor

sectors.

The center display shows an overview of the
vehicle in relation to objects that have been
detected.

The marked sector indicates where the obsta-
cle is located. The closer the vehicle symbol is
to a marked sector forward/rearward, the
closer the detected obstacle is to your vehicle.

The side sectors change color as the distance
between the vehicle and an object decreases.

The audible signals will also speed up the
closer the obstacle is to the vehicle. The vol-
ume of the audio system will be automatically
lowered.

Audible signals for obstacles in front and to
the sides of the vehicle are active when the
vehicle is moving but will cease after the vehi-
cle has been stationary for approx. 2 seconds.
Audible signals for obstacles behind the vehi-
cle will remain active even when the vehicle is
stationary.

If a detected obstacle is within approx. 30 cm
(1 ft) from the front or rear of the vehicle, the
tone will become constant and the active sen-
sor field closest to the vehicle symbol will be
filled in.

At distances within approx. 25 cm (0.8 ft)
from an obstacle to the sides of the vehicle, an
rapid pulsing signal will be given and the
active sector fields will change color from
ORANGE to RED.

The volume of the Park Assist audible signals
can be adjusted while the signal is being given
using the

>II

knob or in the center display's

Top view under

Settings

Besides in the sector closest to the vehicle
symbol, audible warnings are only provided
for objects located directly in the vehicle's
path.

Park Assist front, rear and sides

Park Assist (PAS

) behaves differently

depending on which part of the vehicle is
approaching an obstacle.

Front camera

The warning signal has a continuous tone when the

obstacle is less than approx. 30 cm (1 ft) from the

vehicle.

The Park Assist system's front sensors are
automatically activated when the engine is
started. They are active at speeds
below 10 km/h (6 mph).

The distance monitored extends
approx. 80 cm (2.5 ft) in front of the vehicle.

The Park Assist system is deactivated
when the parking brake is used or when

is selected on vehicles with automatic
transmission.

CAUTION

When installing auxiliary lights: Make sure
these do not obscure the sensors – the
auxiliary lights could be perceived as an
obstacle.

Back

The warning signal has a continuous tone when the

obstacle is less than approx. 30 cm (1 ft) from the

vehicle.

Park Assist System

-------------------------------------------------------------------------------------------------------------------------------------------------------------

DRIVER SUPPORT

* Option/accessory.

337

The rear sensors will be activated if the vehicle
begins rolling backward or if reverse gear is
engaged.

The distance monitored extends
approx. 1.5 meters (5 ft) behind the vehicle.

The Park Assist system's rear sensors will be
automatically deactivated if the vehicle is
backing up with a trailer connected to the
vehicle's electrical system.

When reversing with e.g. a trailer or bike
carrier on the trailer hitch – without Volvo
original trailer cables – the Parking Assist
system may have to be turned off manually
to prevent the sensors from reacting to
these.

Side sensors

The warning signal will begin pulsating rapidly when

the obstacle is less than approx. 25 cm (0.8 ft) from

the vehicle.

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

The distance monitored is approx. 25 cm
(0.8 ft) out from the sides.

The detection area of the side sensors increa-
ses significantly, however, when the steering
angle of the front wheel increases and
depending on the position of the steering
wheel, obstacles up to approx. 90 cm (3 ft)
diagonally behind or in front of the vehicle can
be detected.

Park Assist limitations

Park Assist (PAS

) may not be able to detect

all conditions in all situations and functional-
ity may therefore be limited in certain cases.

The driver should be aware of the following
limitations for Park Assist:

WARNING

•

The parking sensors have dead/blind
spots where objects cannot be
detected.

•

Pay particular attention to people and
animals near the vehicle.

•

Bear in mind that the front end of the
vehicle may swing out towards oncom-
ing traffic during the parking maneuver.

WARNING

Be extra cautious when

reversing if this symbol is

shown when a trailer, bike

carrier or similar is

attached and electrically

connected to the vehicle.
The symbol indicates that

the rear parking assist sensors are

deacti-

vated

and will not warn of any obstacles.

CAUTION

Objects such as chains, thin and glossy
poles or low obstacles may end up in the
"signal shadow" and then go temporarily
undetected by the sensors – the pulsating
tone may then unexpectedly stop instead
of becoming a constant tone as expected.

The sensors cannot detect high objects,
such as protruding ramps.

•

In such situations, pay extra attention
and maneuver/drive the vehicle very
slowly or stop the current parking
maneuver – there may be a high risk of
damage to the vehicle or other objects
since information from the sensors is
not always reliable in such situations.

CAUTION

In some circumstances, the Park Assist
System may produce false warnings due to
external sound sources with the same
ultrasonic frequencies as those the system
works with.

Examples of such sources are horns, wet
tires on asphalt, pneumatic brakes, exhaust
noise from motorcycles, etc.

When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch
protrusion is included when the function
measures the distance to objects behind
the vehicle.

while maneuvering at low speeds.

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

•

Tap the screen to select the camera's field
of vision, e.g. in the area in front/above the
front camera.

The active cameras will be
indicated by a camera symbol
on the vehicle symbol in the
center display.

If the vehicle is equipped with

Park Assist

System

, the distance to detected obstacles

will be illustrated by fields in different colors.

The cameras can be activated automatically or
manually.

Back

The rear camera is located above the license plate.

The rear camera shows a wide area behind the
vehicle. On certain models, part of the bumper
and the towbar (if installed) may be visible.

Objects on the center display may appear to
be leaning slightly. This is normal.

Front camera

The front Park Assist Camera is located in the grille.

The front camera can be useful when pulling
out from areas with limited visibility, such as
when pulling out of a garage. The front camera
is active at speeds up to 25 km/h (16 mph)
and is automatically turned off when the vehi-
cle exceeds this speed.

If the vehicle does not reach a speed of
50 km/h (30 mph) and speed falls below
22 km/h (14 mph) within 1 minute after the
front camera turns off, the camera will be
reactivated.

Park Assist Camera trajectory

lines

The Park Assist Cameras (PAC

104

) use trajec-

tory lines and fields on the screen to indicate
the vehicle's position in relation to its imme-
diate surroundings.

Example of trajectory lines

The trajectory lines show the anticipated tra-
jectory for the vehicle's outermost dimensions

based on the current position of the steering
wheel and can help simplify parallel parking,
backing into tight spaces or attaching a trailer.

The lines on the screen are projected as if they
were painted lines on the ground behind the
vehicle and are directly affected by the way in
which the steering wheel is turned. This
makes it possible for the driver to see path the
vehicle will take, even if he/she turns the
steering wheel.

These lines also indicate the outermost limits
that any object (towbar, rearview mirrors, cor-
ners of the body, etc.) extends out from the
vehicle.
