Set warning distance
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 Warning
(p. 193) 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 current settings can be controlled via the
centre console's screen and the menu system
(p. 109) MY CAR.
Maintenance
Camera and radar sensor
21
.
For the sensors to work correctly, they must be
kept clear of dirt, ice and snow, and be cleaned
regularly with water and car shampoo.
Dirt, ice and snow covering the sensors will
reduce their function and may prevent meas-
urement.

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 (see (1) in the illustration (p. 223)) 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 warn-
ing 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. 182) 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
22
- 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. 196). Read more about radar sensor limita-
tions (p. 210).
If warnings are perceived as being too frequent
or disturbing then the warning distance can be
reduced (p. 226). This would lead to the system
warning at a later stage, which reduces the total
number of warnings.
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.

For cyclists, the warning and full brake intervention may come very late or simultaneously.

Collision warning system* - camera
sensor limitations
"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, bicycle or vehicle in front that are
stationary or moving in the same direction.
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. 237)
•
Driver Alert Control - DAC (p. 242)
•
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.
Cause
Action
The windscreen sur-
face in front of the
camera is dirty or cov-
ered with ice or snow.
Clean the windscreen
surface in front of the
camera from dirt, ice
and snow.
Thick fog, heavy rain
or snow means that
the camera does not
work sufficiently well.
No action. At times
the camera does not
work during heavy rain
or snowfall.
The windscreen sur-
face in front of the
camera has been
cleaned but the mes-
sage remains.
Wait. It may take sev-
eral minutes for the
camera to measure
the visibility.
Dirt has appeared
between the inside of
the windscreen and
the camera.
Visit a workshop to
have the windscreen
inside the camera
cover cleaned - an
authorised Volvo

BLIS*
BLIS (Blind Spot Information) is a function
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
•
rapidly approaching vehicles in the left and
right-hand lanes closest to the car.
The BLIS function CTA (p. 235) (Cross Traffic
Alert) is a driver's aid intended to provide a warn-
ing about:
•
crossing traffic when the car is reversed.
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.

the car is overtaken on both sides at the
same time then both lamps illuminate.
Maintenance
The sensors for the BLIS functions are located
inside the rear wing/bumper on each corner of
the car.
Keep this surface clean - also on the left-hand side.
•
To ensure optimal functionality the areas in
front of the sensors must be kept clean.

BLIS* - operation
BLIS (Blind Spot Information) is a function
designed for providing support for the driver
when driving in dense traffic on roads with sev-
eral lanes in the same direction.
Activate/deactivate BLIS
BLIS is activated when the engine is started. This
is confirmed by the indicator lamps in the door
panels flashing once.
Button for activating/deactivating.
The BLIS function can be deactivated/activated
by pressing the BLIS button on the centre con-
sole.
Some combinations of the selected equipment
leave no vacant space for a button in the centre
console - in which case the function is handled
by the car's menu system MY CAR (p. 109).
When BLIS is deactivated/activated the lamp in
the button extinguishes/illuminates and the com-
bined instrument panel confirms the change with
a text message. The door panel indicator lamps
flash once upon activation.
To extinguish the message:
•
Press the left stalk switch OK button.
or
•
Wait approx. 5 seconds - the message extin-
guishes.
When BLIS operates
Principle for BLIS: 1. Zone in blind spot. 2. Zone for rap-
idly approaching vehicle.
The BLIS function is active at speeds above
10 km/h (6 mph).
The system is designed to react when:
•
the driver's vehicle is overtaken by other
vehicles
•
the driver's vehicle is rapidly caught up by
another 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.
WARNING
BLIS does not work in sharp bends.
BLIS does not work when the car is being
reversed.
Limitations
•
Dirt, ice and snow covering sensors can
reduce functionality and make it impossible
to provide warnings. BLIS cannot detect haz-
ards if it is covered.
•
Do not affix any objects, tape or labels in the
area of the sensors.
•
BLIS is deactivated when a trailer is con-
nected to the car's electrical system.

BLIS - symbols and messages (p. 237)
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. 233).
Activate/deactivate CTA
CTA is activated when the engine is started. This
is confirmed by the indicator lamps for BLIS in
the door panels flashing once.
On/Off for parking assistance and CTA sensors.
The CTA function can be deactivated/activated
separately with the Parking assistance (p. 254)
On/Off button. The BLIS lamps flash once on
reactivation.
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.
When CTA operates
Principle for CTA.
CTA supplements the BLIS function by being
able to see crossing traffic from the side during
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
||
DRIVER SUPPORT
236
detect smaller objects, such as cyclists and
pedestrians.
CTA is only active during reversing and is acti-
vated automatically when the gearbox's reverse
position is selected.
•
If CTA detects something approaching from
the side, an acoustic warning signal sounds.
The signal comes from either the left or the
right-hand speaker, depending on the direc-
tion from which the object is approaching.
•
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. 254).
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.
Maintenance
The sensors for the BLIS and CTA functions are
located inside the rear wing/bumper on each
corner of the car.

Road Sign Information (RSI)*
The Road Sign Information function (RSI – Road
Sign Information) helps the driver to remember
which speed-related road signs the car has
passed.
||
DRIVER SUPPORT
* Option/accessory.
238
Examples of readable speed related signs
24
.
The RSI function gives information on current
speed, e.g. that a motorway or road is starting/
ending and when overtaking is prohibited.
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 maximum permitted speed.
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. 109).
2. Highlight
Road sign information
by press-
ing the OK/MENU button once and go back
out with EXIT.

Road Sign Information (RSI)* -
operation
The Road Sign Information function (RSI
25
) reg-
isters and shows road signs in different ways
depending on the sign and the situation.
Recorded speed information
26
.
When RSI has recorded a road sign with an
imposed speed, the combined instrument panel
displays the sign as a symbol.
Together with the symbol for
the current speed limit, a sign
26
showing that overtaking is pro-
hibited may also be displayed
where appropriate.
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
26
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

.
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.

Additional signs
Examples of additional signs
26
.
Sometimes different speed limits are signposted
for the same road - an additional sign then indi-
cates the circumstances under which the differ-
ent speeds apply. The road section may be par-
ticularly susceptible to accidents in rain and/or
fog, for example.
An additional sign relating to rain is displayed
only if the windscreen wipers are in use.
The speed applicable on an exit
is indicated in certain markets
by means of an additional sign
containing an arrow.
Speed signs linked to this type
of additional sign are displayed
only if the driver is using the direction indicator.
Some speeds are applicable
only after e.g. a specific dis-
tance or at a certain time of
day. The driver's attention is
drawn to the situation by
means of a symbol for an addi-
tional sign under the symbol
showing speed.
A symbol for additional sign in
the form of an empty frame
under the combined instrument
panel's speed symbol
26
means
that RSI has detected an addi-
tional sign with supplementary
information for the current
speed limit.
Speed Alert On/Off
The
Speed Limit Warning
subfunction for RSI
is selectable - the driver can select On or Off.
The speed warning is given in
the form of the combined
instrument panel's symbol
26
for
maximum permitted speed
temporarily flashing when the
speed is exceeded by 5 km/h
(5 mph) or more.

limitations
The Road Sign Information (RSI
27
) function may
have limitations in certain situations.
The camera sensor for RSI has limitations just
like the human eye. Find out more about this in
the section on the camera sensor limitations
(p. 229)).
Signs which indirectly provide information on a
prevailing speed limit, e.g. name signs for towns/
districts, are not recorded by RSI.
Examples of factors that can reduce RSI are as
follows:
•
Faded signs
•
Signs positioned on bends
•
Rotated or damaged signs
•
Signs positioned high above the roadway
•
Fully/partially obscured or poorly positioned
signs
•

Driver Alert System*
The Driver Alert System is intended to assist dri-
vers whose driving ability is deteriorating or who
are inadvertently leaving the lane they are driving
on.
The Driver Alert System consists of different
functions which can either be switched on at the
same time or individually:
•
Driver Alert Control - DAC (p. 243).
•
Lane Departure Warning - LDW (p. 245).
or
•
Lane Keeping Aid - LKA (p. 249)
A switched-on function is set in standby mode
and is not activated automatically until speed
exceeds 65 km/h (40 mph).
The function is deactivated again when speed
decreases to below 60 km/h (37 mph).
Both functions use a camera which is dependent
on the lane having side markings painted on
each side.

WARNING
Driver Alert System does not work in all situa-
tions but is designed merely as a supplemen-
tary aid.
The driver always bears ultimate responsibility
for ensuring that the vehicle is driven safely.

•
Driver Alert Control (DAC)*
The DAC function is intended to attract the driv-
er's attention when he/she starts to drive less
consistently, e.g. if he/she becomes distracted
or starts to fall asleep.
The objective for DAC is to detect slowly deterio-
rating driving ability and it is primarily intended for
major roads. The function is not intended for city
traffic.
A camera detects the side markings painted on
the carriageway and compares the section of the
road with the driver's steering wheel movements.
The driver is alerted if the vehicle does not follow
the carriageway evenly.
In some cases driving ability is not affected
despite driver fatigue. In which case there may
not be any warning issued for the driver. For this
reason it is always important to stop and take a
break in the event of any signs of driver fatigue,
irrespective of whether or not DAC issues a
warning.
The function must not be used to extend a
period of driving. Always plan breaks at regu-
lar intervals, and make sure you are well
rested.
Limitation
In some cases the system may issue a warning
despite driving ability not deteriorating, for exam-
ple:
•
in strong side winds
•
on rutted road surfaces.
The camera sensor has certain limitations
(p. 229).
