(p. 272) Steering assistance during collision
risks from oncoming traffic
This sub-function can help assist a distracted
driver who has not noticed that the vehicle is
veering into oncoming traffic. The function provides assistance by swerving your vehi-
cle back into your own lane.
Oncoming vehicles
Own vehicle
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly
visible traffic lane markings/lines.
If your vehicle is starting to veer from your own
lane and a vehicle is approaching from the oppo-
site direction, this function can help the driver
steer the vehicle back into its own lane. However, the function will not provide steering
assistance if the turn signal is used. The function
will also not be activated if it detects that the
driver is actively operating the vehicle.
After the system has automatically intervened,
this text message will appear in the instrument
panel:
• Collision avoidance assistance –
Automatic intervention
WARNING •
The "Steering assistance at risk of head-
on collision" subfunction is supplemen-
tary driver support intended to improve
driving safety – it cannot handle all situa-
tions in all traffic, weather and road condi-
tions.
• Pilot Assist is only activated if there is a
high risk of collision – you must therefore
never wait for the function to intervene.
• The function is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

• Steering assistance at risk of collision
(p. 372) Limitations of steering assistance
during collision risks from
oncoming traffic
The function may have limited functionality in
certain situations and not intervene, e.g.:
•
for smaller vehicles such as motorcycles
• on roads that do not have clear lane mark-
ings
• if more than half of your vehicle has moved
into the adjacent lane
• outside the speed range 60-140 km/h
(37-87 mph)
• when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").
Functionality may also be reduced in other situa-
tions, such as: • road work
• winter driving conditions
• narrow roads
• poor road surfaces
• a very sporty driving style
• bad weather with reduced visibility.
In these demanding driving conditions, the func-
tion may not be able to properly assist the driver.
In these situations, it is recommended that it is
turned off.

risks from behind*
If you become distracted and do not notice your
vehicle starting to veer out of the lane while
another vehicle is approaching from behind or is
in your vehicle's blind spot, this sub-function can
help provide assistance. The function provides assistance by steering your vehi-
cle back into your own lane.
Another vehicle in blind spot zone
Own vehicle
If your vehicle is beginning to veer out of your
lane while another vehicle is in your blind spot or
another vehicle is rapidly approaching in the next
lane, this function can help the driver steer the
vehicle back into its own lane.
Even if the driver intentionally changes lanes
using a turn signal without noticing another vehi- cle approaching, the function can provide assis-
tance.
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly

Park Assist*
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating
distances to obstacles using audible signals and
graphics in the center display. Display view showing obstacle zones and sensor sec-
tors.
The center display shows an overview of the vehi-
cle in relation to objects that have been detected.
The marked sector indicates where the obstacle
is located. The closer the vehicle symbol is to a
marked sector, the closer the detected obstacle
is to your vehicle.
The audible signals will also speed up the closer
the obstacle is to the vehicle. The volume 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 vehicle has been
stationary for approx. 2 seconds. Audible signals
for obstacles behind the vehicle will remain active
even when the vehicle is stationary.
If a detected obstacle is within 30 cm (1 ft) from
the front or rear of the vehicle, the tone will
become constant and the active sensor's field
closest to the vehicle symbol will be filled in.
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.
NOTE •
Acoustic warnings are only given for
objects directly in front of the vehicle's
path.
WARNING •
The Parking Assist function is supple-
mentary driver support intended to facili-
tate driving and help make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.
• The parking sensors have dead/blind
spots where objects cannot be detected.
• Pay particular attention to people and
animals near the vehicle.
• Parking Assist is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

DRIVER SUPPORT
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.
