Collision warning system*
"Collision Warning with Auto Brake and Cyclist
and Pedestrian Detection" is an aid to assist the
driver when there is a risk of colliding with a
pedestrian, cyclist or vehicle in front that are sta-
tionary or moving in the same direction.
"Collision Warning with Auto Brake and Cyclist
and Pedestrian Detection" is activated in situa-
tions where the driver should have started brak-
ing earlier, which is why it cannot help the driver
in every situation.
"Collision Warning with Auto Brake and Cyclist
and Pedestrian Detection" is designed to be acti-
vated as late as possible in order to avoid unnec-
essary intervention.
"Collision Warning with Auto Brake and Cyclist
and Pedestrian Detection" can prevent a collision
or reduce collision speed.
"Collision Warning with Auto Brake and Cyclist
and Pedestrian Detection" must not be used as
an excuse for the driver to change his/her driving
style. If the driver solely relies on Collision Warn-
ing with Auto Brake to do the braking, there
might be a risk of a collision sooner or later.
Two system levels
Depending on how the car is equipped, the "Col-
lision Warning with Auto Brake and Cyclist and
Pedestrian Detection" function may appear in
two variants:
Level 1
The driver is merely warned
19
of occurring obsta-
cles by means of visual and acoustic signals - no
automatic braking intervenes, the driver must
himself brake.
Level 2
The driver is warned of occurring obstacles by
means of visual and acoustic signals - the car is
braked automatically if the driver himself does not
act within a reasonable time.
Maintenance of the internal components of
the "Collision Warning with Auto Brake and
Cyclist and Pedestrian Detection" must only
be performed at a workshop - an authorised
Volvo workshop is recommended.

Audio-visual warning signal in the event of a
collision risk.
Radar sensor
21
Camera sensor
Collision Warning with Auto Brake executes
three steps in the following order:
1. Collision warning
2. Brake support
21
3. Auto Brake
21
The collision warning system and City
Safety
™ (p. 221) complement each other.
1 - Collision warning
The driver is first warned of a potentially immi-
nent collision.
The collision warning system can detect pedes-
trians, cyclists or vehicles that are stationary or
moving in the same direction as your car and are
located in front of you.
If there is a risk of collision with a pedestrian,
cyclist or a vehicle then the driver's attention is
attracted with a flashing red warning signal (1)
and an acoustic signal.
2 - Brake support
If the risk of collision has increased further after
the collision warning then the brake support is
activated.
This means that the brake system is prepared for
rapid braking by applying the brakes lightly, which
may feel like a slight jolt.
If the brake pedal is depressed sufficiently
quickly then full brake function is implemented.
Brake support also reinforces the driver's braking
if the system considers that the braking is not
sufficient to avoid a collision.
3 - Auto Brake
The automatic brake function is activated last.
If in this situation the driver has not yet started to
take evasive action and the risk of collision is
imminent then the automatic braking function is
deployed - this takes place irrespective of
whether or not the driver brakes. Braking then
takes place with full brake force in order to
reduce collision speed, or with limited brake force
if it is sufficient to avoid a collision. For cyclists,
the warning and full brake intervention may come
very late or simultaneously.

WARNING
The collision warning system does not
engage in all driving situations or traffic,
weather or road conditions. The collision
warning system does not react to vehicles or
cyclists driving in another direction to the car
or to animals.
Warning only activated in the event of a high
risk for collision. This section "Function" and
the section "Limitations" inform about limita-
tions that the driver must be aware of before
using the Collision Warning system with Auto
Brake.
Warnings and brake interventions for pedes-
trians and cyclists are deactivated at vehicle
speeds above 80 km/h (50 mph).
Warnings and brake interventions for pedes-
trians and cyclists do not work in darkness
and tunnels - not even when streetlights are
lit.
The auto-brake function can prevent a colli-
sion or reduce collision speed. To ensure full
brake performance, the driver should always
depress the brake pedal - even when the car
auto-brakes.
Never wait for a collision warning. The driver is
always responsible that the correct distance
and speed are maintained - even when the
collision warning system with auto-brake is
used.

Collision warning system* -
detection of cyclists
The function only "sees" cyclists from behind, who are
travelling in the same direction.
Optimal example of what the system interprets as a
cyclist - with clear body and bicycle contours, directly
from behind and in the car's centre line.
Optimal performance of the system requires that
the system function that detects a cyclist
receives as unambiguous information as possible
about the body and bicycle contours - this implies
the opportunity to identify the bicycle, head, arms,
shoulders, legs, upper and lower body combined
with a normal human pattern of movement.
If large parts of the cyclist's body or bicycle are
not visible to the function's camera then the sys-
tem cannot detect a cyclist.
•
For the function to be able to detect a cyclist,
he/she must be an adult and riding an "adult
bicycle".
•
The function can only detect cyclists directly
from behind and who are travelling in the
same direction - not at an angle from behind,
not from the side.

rearward-facing red
reflector, fitted at least 70 cm above the
roadway.
•
Cyclists travelling on the left or right-hand
edge of the car's imagined/extended side
lines may be detected late or not at all.
•
The function's capacity to detect cyclists at
dusk and dawn is limited - just like the
human eye.
•
The function's capacity to detect cyclists is
deactivated when driving in darkness and
tunnels - even when streetlights are lit.
•
For optimum bicycle detection, the City
Safety

WARNING
Collision Warning with Auto Brake & Cyclist
Detection is a means of assistance.
The function cannot detect:
•
all cyclists in all situations and does not
see partially obscured cyclists, for exam-
ple.
•
cyclists in clothing that obscures the con-
tours of the body or who are approaching
from the side.
•
bicycles that have no rearward-facing red
reflector.
•
bicycles loaded with large objects.
The driver is always responsible that the vehi-
cle is driven properly and with a safety dis-
tance adapted to the speed.

detection of pedestrians
Optimal examples of what the system regards as pedes-
trians with clear body contours.
Optimal performance of the system requires that
the system function that detects pedestrians
receives as unambiguous information as possible
about the contours of the body - this implies the
opportunity to identify the head, arms, shoulders,
legs, upper and lower body combined with a nor-

If large parts of the body are not visible to the
function's camera then the system cannot detect
a pedestrian.

pedestrians in all situations and does not see,
for example:
•
partially obscured pedestrians, people in
clothing that hides their body contour or
pedestrians shorter than 80 cm.
•

Settings for the collision warning system are
made from MY CAR via the centre console
screen and menu system, see MY CAR (p. 113).
Warning signals On and Off
1. Acoustic and visual warning signal in the event of a
collision risk
23
.
It is possible to select whether the collision warn-
ing system's acoustic and visual warning signals
should be switched on or off.
When starting the engine, the setting that was
selected when the engine was switched off is
obtained automatically.
The Brake Support and Auto Brake functions
are always activated - they cannot be deacti-
vated.
Settings for the collision warning system are
made via the centre console's screen and the
menu system MY CAR, see (p. 113).
Light and acoustic signals
When the collision warning system's light and
acoustic warnings are activated, the warning lamp
(no. [1] in previous illustration) is tested each
time the engine is started by briefly illuminating
the warning lamp's separate points of light.
After starting the engine, both light and acoustic
signals are switched off:
•
Search for
Collision warning
in
Driver
support system
in the menu system MY
CAR (p. 113) - and there select to uncheck
the function.

After starting the engine the warning sound can
be activated/deactivated separately:
•
Search for

The warning distance regulates the distance at
which the visual and acoustic warnings are
deployed.
•
Search for
Warning distance
in
Collision
warning
in the menu system MY CAR
Long
,
Normal
or
Short
.
The warning distance determines the system's
sensitivity. Warning distance
Long
provides an
earlier warning. First test with
Long
and if this
setting produces too many warnings, which could
be perceived as irritating in certain situations,
then change to warning distance
Normal
.
Only use warning distance
Short
in exceptional
cases, e.g. for dynamic driving.
When the adaptive cruise control is in use the
warning lamp and warning sound will be used
by the cruise control even if the collision
warning system is switched off.
The collision warning system warns the driver
in the event of a risk of a collision, but the
function cannot shorten driver reaction time.
In order for the collision warning system to be
effective, always drive with Distance Alert
(p. 199) set at time interval 4–5.
Even if the warning distance has been set to
Long
warnings could be perceived as being
late in certain situations, e.g. when there are
large differences in speed or if vehicles in
front brake heavily.
WARNING
No automatic system can guarantee 100 %
correct function in all situations. Therefore,
never test Collision Warning with Auto Brake
by driving at people or vehicles - this may
cause severe damage and injury and risk lives.
Checking settings
The settings required can be controlled on the
centre console display screen.

Collision warning system* -
limitations
The function has certain limitations - for example,
it is not active until 4 km/h (3 mph).
The collision warning system's visual warning sig-
nal may be difficult to notice in the event of
strong sunlight, reflections, when sunglasses are
being worn or if the driver is not looking straight
ahead. The warning sound should therefore
always be activated.
On slippery road surfaces the braking distance is
extended, which may reduce the capacity to avoid
a collision. In such situations the ABS and ESC
(p. 186) systems will provide best possible brak-
ing force with maintained stability.
The visual warning signal can be temporarily
disengaged in the event of high passenger
compartment temperature caused by strong
sunlight for example. If this occurs then the
warning sound is activated even if it is deacti-
vated in the menu system.
•
Warnings may not appear if the distance
to the vehicle in front is small or if steer-
ing wheel and pedal movements are
large, e.g. a very active driving style.
WARNING
Warnings and brake interventions could be
implemented late or not at all if the traffic sit-
uation or external influences mean that the
radar or camera sensor cannot detect a
pedestrian, a vehicle or a cyclist in front cor-
rectly.
The sensor system has a limited range for
pedestrians and cyclists
25
- the system can
give effective warnings and brake interven-
tions for them at vehicle speeds up to
50 km/h (30 mph). For stationary or slow-
moving vehicles, warnings and brake interven-
tions are effective at vehicle speeds up to
70 km/h (43 mph).
Warnings for stationary or slow-moving vehi-
cles could be disengaged due to darkness or
poor visibility.
Warnings and brake interventions for pedes-
trians and cyclists are deactivated at vehicle
speeds exceeding 80 km/h (50 mph).
The collision warning system uses the same
radar sensors as the adaptive cruise control
(p. 203).
If warnings are perceived as being too frequent
or disturbing then the warning distance can be
reduced. This then leads to the system providing
a warning at a later stage, which reduces the
total number of warnings; see Collision warning
system - operation (p. 232).
Collision Warning with Auto Brake is temporarily
deactivated with reverse gear engaged.
Collision Warning with Auto Brake is not acti-
vated at low speeds - below 4 km/h (3 mph),
which is why the system does not intervene in sit-
uations where the car is approaching a vehicle in
front very slowly, e.g. when parking.
In situations where the driver demonstrates
active, aware driving behaviour, a collision warn-
ing may be postponed slightly in order to keep
unnecessary warnings to a minimum.
When Auto Brake has prevented a collision with
a stationary object the car remains stationary for
a maximum of 1.5 seconds. If the car is braked
for a vehicle in front that is moving, then speed is
reduced to the same speed as that maintained by
the vehicle in front.
On a car with manual gearbox the engine stops
when Auto Brake has stopped the car, unless the
driver manages to depress the clutch pedal
beforehand.

Collision warning system* - camera
sensor limitations
The function uses the car's camera sensor,
which has certain limitations.
The car’s camera sensor is also used - as well as
by Collision Warning with Auto Brake - by the
functions:
•
•
Road sign information (p. 243)
•
Driver Alert Control - DAC (p. 247)
•
Keep the windscreen surface in front of the
camera sensor free from ice, snow, mist and
dirt.
Do not stick or attach anything to the wind-
screen in front of the camera sensor as this
may reduce effectiveness or cause one or
more of the systems dependent on the cam-
era to stop working.
The camera sensors have limitations similar to
the human eye, i.e. they "see" worse in darkness,
heavy snowfall or rain and in thick fog for exam-
ple. Under such conditions the functions of cam-
era-dependent systems could be significantly
reduced or temporarily disengaged.
Strong oncoming light, reflections in the carriage-
way, snow or ice on the road surface, dirty road
surfaces or unclear lane markings could also sig-
nificantly reduce camera sensor function when it
is used to scan the carriageway and detect
pedestrians and other vehicles.
The field of vision of the camera sensor is limited,
which is why pedestrians, cyclists and vehicles
cannot be detected in some situations, or they
are detected later than anticipated.
During very high temperatures the camera is
temporarily switched off for about 15 minutes
after the engine is started in order to protect
camera functionality.
Fault tracing and action
If the display shows the message
Windscreen
sensors blocked See manual
then this means
that the camera sensor is blocked and cannot
detect pedestrians, cyclists, vehicles or road
markings in front of the car.
At the same time, this means that - besides Colli-
sion Warning with Auto Brake - the following
functions will not have full functionality either:
•
Active main beam
•
Driver Alert Control
•
Lane Keeping Aid
•
Road sign information
The following table presents possible causes for
a message being shown along with the appropri-
ate action.

BLIS
BLIS (Blind Spot Information System) is a func-
tion designed for providing support for the driver
when driving in dense traffic on roads with sev-
eral lanes in the same direction.
BLIS is a driver's aid intended to provide a warn-
ing about:
•
vehicles in the car's blind spot
•
quickly approaching vehicles in the left and
right lanes closest to the car.
WARNING
BLIS is a supplementary aid and does not
work in all situations.
BLIS is no substitute for a safe driving style
and the use of rearview and door mirrors.
BLIS can never replace the driver's responsi-
bility and attention - it is always the driver's
responsibility to change lanes in a safe man-
ner.

guishes.
When BLIS operates
Principle for BLIS: 1. Zone in blind spot. 2. Zone for
quickly approaching vehicle.
The BLIS function is active at speeds above
10 km/h (6 mph).
The system is designed to react when:
•
the vehicle is overtaken by other vehicles
•
another vehicle is quickly approaching the
vehicle.
When BLIS detects a vehicle in zone 1 or a
quickly approaching vehicle in zone 2, the door
panel BLIS lamp illuminates with a constant glow.
If the driver activates the direction indicator on
the same side as the warning in this situation
then the BLIS lamp will change from a constant
glow to flashing with a more intense light.

BLIS and CTA - symbols and messages
(p. 242)
CTA*
The BLIS function CTA (Cross Traffic Alert) is a
driver aid intended to warn about crossing traffic
when the car is reversing. CTA is a supplement
to BLIS (p. 238).
Activate/deactivate CTA
CTA is activated when the engine is started. This
is confirmed by the indicator lamps in the door
panels flashing once.
On/Off for parking assistance and CTA sensors.
In cars equipped with Parking assistance
(p. 255), the CTA function can be deactivated/
activated separately with the parking assistance
On/Off button.
In cars without a button for parking assistance,
the CTA function can be operated in the menu
system MY CAR (p. 113), as follows:
•
Search for
Cross Traffic Alert
under
BLIS
and uncheck - the CTA function is then
deactivated.
However, the BLIS function remains activated
after the CTA has been deactivated.
WARNING
CTA is a supplementary aid and does not
work in all situations.
CTA is no substitute for a safe driving style
and the use of rearview and door mirrors.
CTA can never replace the driver's responsi-
bility and attention - it is always the driver's
responsibility to reverse in a safe manner.

reversing, such as when reversing out of a park-
ing space.
CTA is primarily designed to detect vehicles. In
favourable conditions, it may also be able to
detect smaller objects, such as cyclists and
pedestrians.
CTA is only active during reversing and is acti-
vated automatically when reverse is selected at
the gearbox.
•
If CTA detects something approaching from
the side, an acoustic warning signal sounds.
The signal comes from either the left or the
right speaker depending on which direction
the approaching object is coming from.
•
CTA also warns by illuminating the BLIS
lamps.
•
An additional warning is provided in the form
of an illuminated icon in the display screen's
PAS graphics (p. 255).
Limitations
CTA does not perform optimally in all situations,
but has a certain limitation - for example, the CTA
sensors cannot "see" through other parked vehi-
cles or obstructing objects.
Here are some examples of when CTA's "field of
vision" may be limited from the beginning and
approaching vehicles cannot therefore be
detected until they are very close:
The car is parked deep inside a parking slot.
Blind CTA sector.
Sector where CTA can detect/"see".
In an angled parking slot CTA can be completely "blind"
on one side.
However, when the driver is slowly reversing the
car, the angle is changed in relation to the vehi-
cle/object that is blocking, at which the blind
sector rapidly decreases.
Examples of further limitations:
•
Dirt, ice and snow covering sensors can
reduce functionality and make it impossible
to provide warnings. CTA cannot detect haz-
ards if it is covered.
•
CTA is deactivated when a trailer is con-
nected to the car’s electrical system.
Repair of the BLIS and CTA functions' com-
ponents or repainting the bumpers must only
be performed by a workshop - an authorised
Volvo workshop is recommended.

Road Sign Information* (RSI)
The Road Sign Information function (RSI
28
)
helps the driver to observe speed-related road
signs and certain prohibition signs as the car
passes them.
Examples of readable signs
29
.
RSI provides information about such things as
current speed, when a motorway or road is star-
ting/ending, when overtaking is prohibited or
when the direction of travel is one-way.
If both a sign for motorway/road for motorised
traffic and a sign showing the maximum permit-
ted speed are passed, RSI decides to show the
sign symbol for motorway/road for motorised
traffic.
WARNING
•
The Road Sign Information 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.
•
Road Sign Information is not a substitute
for the driver's attention and judgement.
The driver is always responsible for
ensuring the car is driven in a safe man-
ner, at the appropriate speed, with an
appropriate distance to other vehicles,
and in accordance with current traffic
rules and regulations.
RSI On/Off
The function for Road Sign Information is select-
able - the driver can select On or Off.
Activate RSI as follows:
1. Search and locate the function in the menu
system MY CAR, see MY CAR (p. 113).

Road Sign Information (RSI)* -
operation
The Road Sign Information function (RSI
30
) reg-
isters and shows road signs in different ways
depending on the sign and the situation.
Example
31
of detected speed information.
When RSI has recorded a road sign with an
imposed speed, the combined instrument panel
displays the sign as a symbol.
An additional
31
sign, such as
"no overtaking", may be shown
together with the speed limit
symbol.
End of speed limit or motorway
When RSI detects an "indirect speed sign" that
means end of current speed limit - e.g. at end of
motorway - a symbol with the corresponding road
sign is shown in the combined instrument panel.
Examples of indirect speed sign
31
are:
End of all restrictions.
End of motorway.
The symbol in the combined instrument panel
extinguishes after 10-30 seconds and remains
extinguished until the next speed-related sign is
passed.
Changed speed limit
On passing a direct speed sign when the speed
limit changes, a symbol with the corresponding
road sign is shown in the combined instrument
panel.
Example of a direct speed
sign
31
.
The symbol in the combined instrument panel
extinguishes after approx. 5 minutes and remains
extinguished until the next speed-related sign is
passed.
Sensus Navigation
If the car is equipped with Sensus Navigation,
speed information is read from the navigation
unit in the following cases:
•
On detection of signs that indirectly indicate
a speed limit, such as motorway, dual car-
riageway and city limit signs.
•
If a previously detected speed sign is
assumed not to apply any longer, but no new
sign has been detected.
