Road Sign Information* (p. 357) Driver Alert Control
The Driver Alert Control (DAC) function is
designed to help capture the driver become
aware of erratic behavior, e.g. if the driver is dis-
tracted or showing signs of fatigue.
The objective of DAC is to detect slowly deterio-
rating driving behavior and is primarily intended to
be used on major roads. The function is not
intended for use in city traffic.
DAC is activated when the vehicle's speed
exceeds 65 km/h (40 mph) and remains active
as long as speeds are above 60 km/h (37 mph). A camera monitors the traffic lane's marker lines
and compares the direction of the road with the
driver's movements of the steering wheel. If the driving behavior becomes
noticeably erratic, the driver will
be alerted by this symbol in the
instrument panel and the mes-
sage
Time for a break
soon?.
If driving behavior does not improve but instead
becomes even more erratic, the driver will be
alerted by the same symbol in the instrument
panel, an audible signal and the message Time
for a break. If the Rest Stop Guidance function is activated
in Sensus Navigation* when the Time for a
break warning is given, suggestions will also be provided for suitable places to take a break. 105

382Park Assist front, rear and sides
Park Assist has different parameters depending
on which part of the vehicle is approaching an
obstacle.
Back Note: This illustration is general and details may vary
depending on model.
The rear sensors will be activated if the vehicle
begins rolling backward or if reverse gear is
engaged.
The distance monitored begins
approx. 1.5 meters (5 feet) behind the vehicle.
The rear sensors will be automatically deactivated
if the vehicle is backing up with a trailer attached.
NOTE When reversing with e.g. a trailer or bike car-
rier 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
Park Assist's side sensors are automatically acti-
vated when the engine is started. They are active
at speeds below 10 km/h (6 mph).
The distance monitored begins approx. 30 cm
(1 ft) from the sides. The audible signal for obsta-
cles along the sides of the vehicle is emitted
from the side speakers.
Front camera Note: This illustration is general and details may vary
depending on model.
Park Assist's front sensors are automatically acti-
vated when the engine is started. The front sen-
sors are active at speeds below 10 km/h
(6 mph).
The distance monitored begins approx. 80 cm
(2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivated
when the parking brake is applied or when P
is selected on vehicles with automatic trans-
mission.

• Park Assist* (p. 381) Park Assist limitations
Park Assist may not be able to detect all condi-
tions in all situations and functionality may there-
fore be limited in certain cases.
The driver should be aware of the following limi-
tations for Park Assist:
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 infor-
mation from the sensors is not always
reliable in such situations.
CAUTION In some circumstances, the Park Assist Sys-
tem may produce false warnings due to exter-
nal 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.
NOTE When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch pro-
trusion is included when the function meas-
ures the distance to objects behind the vehi-
cle.

120
are located in the rearview mirrors.
The side cameras can show views along each
side of the vehicle.
Related information
• Park Assist Camera* (p. 386) Park Assist Camera trajectory lines
The Park Assist Camera uses trajectory lines
and fields on the screen to indicate the vehicle's
position in relation to its immediate surround-
ings. Example
121
of trajectory lines.
The trajectory lines show the anticipated trajec-
tory for the vehicle's outermost dimensions based
on the current position of the steering wheel to 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 enables
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, corners of
the body, etc.) extends out from the vehicle.
NOTE
•
When reversing with a trailer that is not
electrically connected to the vehicle, the
screen guide lines show the path the
vehicle will take – not the trailer.
• The screen does not show guide lines
when a trailer is electrically connected to
the vehicle's electrical system.
• Guide lines are not shown when zooming
in. 120

CAUTION•
Bear in mind that when the rearward
camera view is selected, the screen only
shows the area behind the vehicle – pay
attention to the sides and front of the
vehicle when steering while reversing.
• The same applies to the reverse – pay
attention to what is happening with the
rear parts of the vehicle when the front
camera view is selected.
• Note that the guide lines show the short-
est path – pay extra attention to ensure
that the vehicle sides do not come in
contact with/travel over anything when
steering while driving forward or that the
vehicle front moves toward/over anything
when steering while reversing.Trajectory lines in 360° view* 360° view with trajectory lines

In the 360° view, trajectory lines are shown
behind, in front of, or to the sides of the vehicle,
depending on the direction of travel.
• When driving forward: Front lines
• When backing up: Side lines and rear lines.
When the front or rear camera is selected, the
trajectory lines will be shown regardless of the
vehicle's direction of travel.
With a side camera selected, the trajectory lines
will only be shown if the vehicle is backing up.Trajectory lines for a towbar* Towbar with trajectory line

Starting the Park Assist Camera
The Park Assist Camera starts automatically
when reverse gear is engaged or can be started
manually using one of the center display's func-
tion buttons.
Camera view when backing upWhen reverse gear is engaged, the screen shows
the rear view 123
.
Camera view when manually starting
the camera
Start the Park Assist Camera
using this button in the center
display's Function view.
The screen will first show the
most recently used camera
view. However, each time the
engine is started, the previous side view will be
replaced by the 360° view and a previously dis-
played zoomed-in rear view will be replaced by
the regular rear view.
Automatically deactivating the cameraFront view switches off when the vehicle's speed
reaches 25 km/h (16 mph) to help avoid dis-
tracting the driver. It will be automatically reactiva-
ted if the vehicle's speed falls below 22 km/h
(14 mph) within 1 minute as long as the vehicle's
speed has not exceeded 50 km/h (31 mph). Other camera views switch off at 15 km/h
(9 mph) and are not reactivated.
