Rear Collision Warning

*

95

The Rear Collision Warning

96

 (RCW) function

can help the driver to avoid being hit by a
vehicle approaching from behind.

Drivers in vehicles behind can be warned
about an imminent collision by the function
flashing intensively with the direction indica-
tors.

If, at a speed below 30 km/h (20 mph), the
function detects that the car is in danger of
being hit from behind, the seatbelt tensioners
may tension the front seatbelts. The Whiplash
Protection System is also activated in the
event of a collision.

Immediately before a collision from behind,
this function may also activate the foot brake
in order to reduce the forward acceleration of
the car during the collision. However, the foot
brake is only activated if the car is stationary.
The foot brake releases immediately if the
accelerator pedal is depressed.

This function is activated automatically each
time the engine is started.

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

In certain cases the Rear Collision Warning
(RCW) may have difficulty helping the driver
in the event of a collision risk.

This can, for example, be if:

•

the vehicle approaching from behind is
detected too late

•

the vehicle approaching from behind
changes lane at the last moment

•

a trailer, bicycle rack or similar is con-
nected to the car's electrical system - the
function is then deactivated automatically.

NOTE

In certain markets, RCW does 

not

 give a

BLIS

*

The BLIS

98

 function is intended to help the

driver detect vehicles diagonally behind and
to the side of the car so as to provide assis-
tance in heavy traffic on roads with several
lanes in the same direction.

Location of BLIS lamp

BLIS is a driver aid intended to give a warning
of:

•

vehicles in the car's blind spot

•

quickly approaching vehicles in the left
and right lanes closest to the car.

Principle of BLIS

Zone in blind spot

Zone for quickly approaching vehicle

The system is designed to react when:

•

your car is overtaken by other vehicles

•

another vehicle is quickly approaching
your car.

When BLIS detects a vehicle in Zone 1 or a
quickly approaching vehicle in Zone 2, the
indicator lamp on the door mirror on the affec-
ted side illuminates with a constant glow. If
the driver activates the direction indicator on
the same side as the warning, the indicator
lamp will change over from a constant glow to
flashing with a more intense light.

BLIS is active when the driver's vehicle is trav-
elling at a speed above 10 km/h (6 mph).

If passing vehicles drive more than 15 km/h
(9 mph) faster than the driver's vehicle, BLIS
will not react.

NOTE

The lamp illuminates on the side of the car
where the system has detected the vehicle.
If the car is overtaken on both sides at the
same time then both lamps illuminate.

Driver Alert Control

The Driver Alert Control (DAC) function is
intended to help make the driver aware that
he or she is starting to drive less consistently,
e.g. if the driver becomes distracted or starts
to fall asleep.

The objective for DAC is to detect slowly dete-
riorating driving ability and it is primarily
intended for major roads. The function is not
intended for city traffic.

The function is activated when speed exceeds
65 km/h (40 mph) and remains active as long
as the speed is over 60 km/h (37 mph).

DAC reads the position of the car in the lane.

A camera detects the edge markings painted
on the carriageway and compares the align-
ment of the road with the driver’s steering
wheel movements.

The car is being driven erratically in the lane.

If driving behaviour becomes
noticeably inconsistent, the
driver is alerted by this sym-
bol in the driver display, com-
bined with an acoustic signal
and the text message 

Time

to take a break

.

If the car is equipped with Sensus Navigation

*

and has the function 

Rest Stop Guidance

activated, suggestions for an appropriate
place for a break are also displayed.

The warning is repeated after a time if driving
behaviour has not improved.

WARNING

Driver Alert Control should not be used to

extend a period of driving. The driver

should instead plan for breaks at regular

intervals and make sure they are well

rested.

WARNING

An alarm from Driver Alert Control should

be taken very seriously, as a sleepy driver is

often not aware of his/her own condition.
If the alarm sounds or you feel fatigued:

•

Stop the car safely as soon as possible
and rest.

Studies have shown that it is just as dan-

gerous to drive while tired as it is to drive

under the influence of alcohol or other

stimulants.

Limitations of Driver Alert Control

The Driver Alert Control (DAC) function may
have limitations in certain situations.

In some cases the system may issue a warn-
ing despite driving ability not deteriorating, for
example:

•

in strong side winds

•

on rutted road surfaces.

WARNING

In some cases, driving behaviour is not

affected despite driver fatigue – e.g. when

using the Pilot Assist

*

 function – resulting

in the driver not getting a warning from

DAC.
It is therefore important to always stop and

take a break at the slightest feeling of fati-

gue, regardless of whether the function has

given a warning.

NOTE

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

Cross Traffic Alert

*

103

Cross Traffic Alert (CTA) is a driver support
that supplements BLIS

104

 and is designed to

help the driver detect traffic crossing behind
the car when it is reversing.

The 

auto-brake

 subfunction can help the

driver to stop the car in the event of a risk of
collision with an unobserved vehicle.

Examples of areas where CTA can assist the driver to

detect obstacles during reversing.

CTA is primarily designed to detect vehicles. In
favourable conditions it may also be able to
detect smaller objects, such as cyclists and
pedestrians.

The function is only active if the car rolls back-
wards or if reverse gear has been selected.

If CTA senses that something is approaching
from the side, this is also indicated with:

•

an acoustic signal - the sound is heard in
the left-hand or right-hand speaker
according to the direction from which the
object approaches.

•

an illuminated icon in the 

Park Assist

System

 graphic on the screen.

•

an icon on the Park assist camera top
view.

Illuminated icon for Cross Traffic Alert in the 

Park

If the driver does not observe the warning
from CTA and a collision is unavoidable, the

 function takes effect to stop the

car, after which the driver display shows an

The Cross Traffic Alert (CTA) function with

auto-brake

 may have limited functionality in

certain situations. Brake intervention is active
at speeds below 15 km/h.

WARNING

The 

auto-brake

 subfunction can only

detect and brake for other vehicles that are

moving – 

not

 for stationary obstacles, a

cyclist or a pedestrian, for example.

CTA has a certain limitation – the CTA sensors
cannot "see" through other parked vehicles or
obstructions, for example.

Here are some examples of situations where
CTA’s "field of vision" may be already limited
and approaching vehicles cannot therefore be
detected until they are very close:

The car is parked deep inside a parking slot.

In an angled parking slot CTA may be completely

“blind” on one side.

Blind CTA sector.

Sector in which CTA can detect/“see”.

However, as your car slowly reverses, the
angle it makes with the obstructing vehicle/
object changes and the blind sector rapidly
decreases.

Examples of further limitations

•

The 

auto-brake

 subfunction only detects

moving vehicles and therefore 

cannot

"see" and brake for stationary obstacles, a
cyclist or a pedestrian, for example.

•

Dirt, ice and snow covering the sensors
may reduce the functions and deactivate
alerts.

•

CTA is automatically deactivated if a
trailer, bicycle rack or similar is connected
to the car's electrical system.

•

For good performance of CTA, there
should be no bicycle rack, luggage carrier
or similar mounted on the car's towbar.

NOTE

This function uses the car's radar units,

Park Assist

*

The Parking Assistance System (PAS

108

) uses

sensors to assist the driver when manoeu-
vring in tight spaces by indicating the dis-
tance to obstacles through acoustic signals
combined with a graphic in the centre dis-
play.

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 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.

) has dif-

ferent 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.

109

Park Assist System

DRIVER SUPPORT

* Option/accessory.

357

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

111

) can-

not 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.
