Limitations of Lane assistance

In certain demanding conditions lane assis-
tance (LKA

109

) may have difficulty helping the

driver correctly. In such cases it is recom-
mended to switch off this function.

Examples of such conditions are:

•

road works

•

winter road conditions

•

poor road surface

•

a very “sporty” driving style

•

poor weather with reduced visibility

•

roads with unclear or non-existent side
markings

•

sharp edges or lines other than the lane's
side markings

•

as the steering servo for speed-dependent
steering wheel resistance is working at
reduced power – e.g. when cooling due to
overheating.

The function is unable to detect barriers, rails
or similar obstacles at the side of the carriage-
way.

NOTE

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

Steering assistance at risk of

collision

The function 

Collision avoidance assistance

can help the driver reduce the risk of the car
leaving its lane unintentionally and/or collid-
ing with another vehicle or obstacle by
actively steering the car back into its lane
and/or swerving.

The function consists of these subfunctions:

•

Steering assistance upon risk of run-off

•

Steering assistance upon risk of head-on
collision

•

Steering assistance upon risk of rear-end
collision

*

After automatic engagement, the driver dis-
play indicates that this has occurred via a text
message:

Collision avoidance assistance

 

Automatic

intervention

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.

•

•

Driver support functions are not a sub-
stitute for the driver's attention and
judgement. The driver is always
responsible for ensuring the car is
driven in a safe manner, at the appro-
priate speed, with an appropriate dis-
tance to other vehicles, and in accord-
ance with current traffic rules and reg-
ulations.

NOTE

It is always the driver who decides how
much the car should steer – the car can
never take command.

Steering assistance upon risk of

run-off

Steering assistance has a number of subfunc-
tions. Steering assistance in the event of run-
off risk can help the driver and reduce the risk
of the car accidentally leaving the road by
actively steering the car back onto the road.

The function has two activation levels on inter-
vention:

•

385

Steering assistance with brake intervention

Intervention with steering assistance and braking.

Brake intervention helps in situations where
steering assistance alone is not sufficient. The
brake force is adapted automatically depend-
ing on the situation at the time of road run-off.

The function is active within the speed range
65-140 km/h (40-87 mph) on roads with
clearly visible lane markings/lines.

A camera scans the edges of the road and the
painted side markings. If the car is about to
leave the side of the road, the car is steered
back onto the road and if the steering inter-
vention is not enough to avoid run-off, the
brakes are also activated.

However, the function does 

not

 intervene with

either steering assistance or brake interven-
tion if the direction indicators are used. And if
the function detects that the driver is actively

driving the car, activation of the function will
be delayed.

Steering assistance upon risk of

head-on collision

Steering assistance has a number of subfunc-
tions. Steering assistance upon risk of head-
on collision can help a distracted driver who
does not notice that the car is heading into
the opposite lane.

The function can assist by guiding the car back to its

own lane.

The function is active within the speed range
60-140 km/h (37-87 mph) on roads with
clearly visible lane markings/lines.

If the car is about to leave its own lane while
an oncoming vehicle is approaching at the
same time, the function can help the driver to
steer the car back into its own lane.

However, the function does 

not

 intervene with

steering assistance if the direction indicator is
used. And if the function detects that the
driver is actively driving the car, activation of

Steering assistance upon risk of

rear-end collision

*

Steering assistance has a number of subfunc-
tions. Steering assistance if there is a risk of
rear-end collision can help a distracted driver
who does not notice that the car is about to
leave its own lane while an oncoming vehicle
is approaching at the same time, either from
behind or in the blind spot.

The function can assist by steering the car back to its

own lane.

Other vehicle in the blind spot

Your car

If the car is about to leave its own lane while
another vehicle is in the blind spot, or another
vehicle is approaching rapidly in an adjacent
lane at the same time, the function can help

the driver to steer the car back into its own
lane.

The function can even assist if the driver inten-
tionally changes lanes using direction indica-
tors without noticing that another vehicle is
approaching.

The function is active within the speed range
60-140 km/h (37-87 mph) on roads with
clearly visible lane markings/lines.

The lamps in the door mirrors flash during
steering intervention, regardless of whether
the BLIS

Limitations for steering assistance

at risk of collision

In certain situations the function may have
limited functionality and fail to intervene in
the following cases, for example:

•

for small vehicles, such as motorcycles

•

if the majority of the car has steered into
the adjacent lane

•

on roads/in lanes with unclear or non-exis-
tent lane markings

•

outside the speed range 60-140 km/h
(37-87 mph)

•

as the steering servo for speed-dependent
steering wheel resistance is working at
reduced power – e.g. when cooling due to
overheating.

Other demanding situations can include:

•

road works

•

winter road conditions

•

narrow roads

•

poor road surface

•

a very “sporty” driving style

•

poor weather with reduced visibility.

In these demanding situations, the function
may have difficulty helping the driver correctly.
In such cases it is recommended to switch off
this function.

NOTE

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

Park Assist

*

The Park Assist Pilot function can assist the
driver when manoeuvring in tight spaces by
indicating the distance to obstacles through
acoustic signals combined with a graphic in
the centre display.

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's 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.

Park Assist Pilot front, rear and

along the sides

*

Park Assist Pilot has different 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.

The sensors for reverse are activated if the car
rolls backward without a gear engaged or

DRIVER SUPPORT

* Option/accessory.

391

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 cannot
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.
