Steering assistance at risk of

collision

The 

Collision avoidance assistance

 function

is intended to help the driver reduce the risk of
the vehicle inadvertently veering from the traffic
lane and/or colliding with another vehicle or
obstacle by actively steering the vehicle back
into the lane and/or swerving out of the way.

Collision avoidance assistance

 consists of

three sub-functions:

•

Run-Off Mitigation with steering assistance

•

Steering assistance during collision risks
from oncoming traffic

•

Steering assistance during collision risks
from behind*

After the system has automatically intervened,
this text message will appear in the instrument
panel:

•

Collision avoidance assistance

 –

373

Run-Off Mitigation with steering

assistance

This sub-function is intended to help reduce the
risk of the vehicle inadvertently running off the
road by actively steering the vehicle back onto
the road.

The function is active at speeds between
65-140 km/h (40-87 mph) on roads with clearly
visible traffic lane markings/lines.

The system uses a camera to monitor the edges
of the road and the painted side marker lines. If
the vehicle is about to cross the edge of the road,
the function will attempt to steer the vehicle back
onto the road. If this is not sufficient to keep the
vehicle on the road, the brakes will also be
applied.

However, the function will not provide either
steering assistance or braking 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 run-
off" subfunction is supplementary driver
support intended to help improve driving
safety – it cannot handle all situations in
all traffic, weather and road conditions.

•

The function cannot detect barriers, rails
or similar obstacles at the side of the
road.

•

"Steering assistance at risk of run-off" 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 appropri-
ate speed, with an appropriate distance to
other vehicles, and in accordance with
current traffic rules and regulations.

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 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 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 approx. 30 cm
(1 ft) from the front or rear of the vehicle, the
tone will become constant and the active sen-
sor's 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 puls-
ing 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

.

NOTE

•

Besides in the sector closest to the vehi-
cle symbol, audible warnings are only pro-
vided for objects located directly in 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.

Park Assist front, rear and sides

Park Assist has different parameters depending
on which part of the vehicle is approaching an
obstacle.

Front camera

Continuous tone warning signal when the obstacle is
less than approx. 30 cm (1 ft) from the vehicle 

107

.

Park Assist's front sensors are automatically acti-
vated 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.

NOTE

The Parking Assist system is deactivated
when the parking brake is applied or when P
is selected on vehicles with automatic trans-
mission.

CAUTION

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

Back

Continuous tone warning signal when the obstacle is
less than approx. 30 cm (1 ft) from the vehicle 

107

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 Parking Assist system's rear sensors will be
automatically deactivated if the vehicle is backing
up with a trailer connected to the vehicle's elec-
trical system.

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.
