Camera and radar sensor's field of vision
The camera and radar sensor have limited fields
of vision. In some situations they may detect a
vehicle, large animal, pedestrian or cyclist later
than expected or not detect them at all.
Other vehicles that are dirty may be detected
later than others and in dark conditions, motorcy-
cles may be detected late or not at all.
If a text message is displayed in the instrument
panel indicates that the camera or radar sensor
are blocked, it may be difficult for City Safety to
detect a vehicle, pedestrian or cyclist and the
system's functionality may be reduced.
WARNING
Text messages may not be displayed in all sit-
uations in which the camera and/or radar
sensor are blocked. It is therefore essential to
keep the windshield in front the camera/radar
sensor clean and free from snow, ice, etc.
Camera and radar sensor components should
only be serviced or replaced by a trained and
qualified Volvo service technician.
Action by the driver
Backing up
City Safety is temporarily deactivated while the
vehicle is backing up.
Low speed
City Safety is not activated at very low speeds
(under approx. 3 mph (4 km/h). This means that
the system will not be triggered if your vehicle
approaches a vehicle ahead at very low speed,
such as when parking.
Active driver
Action by the driver always has priority. For this
reason, City Safety may not react or react later
than expected in situations in which the driver is
actively operating the vehicle, even if a collision is
imminent. This is also done to help eliminate
excessive warnings.
Other limitations
City Safety uses the vehicle's camera and radar
sensor, which have certain general limitations.
See the articles "Camera limitations" and "Radar
sensor limitations" for additional information.
WARNING
•
Warnings and braking may be delayed or
not occur at all if traffic, weather or other
conditions prevent the camera and/or
radar sensor from detecting pedestrians,
cyclists, large animals or other vehicles
correctly.
•
Other vehicles can only be detected in
darkness if their headlights and taillights
are clearly visible.
•
The sensors have a limited range for
pedestrians and cyclists. The system
functions best at relative speeds up to
30 mph (50 km/h). For stationary or
slow-moving vehicles, the system func-
tions best at speeds up to approx.
43 mph (70 km/h).
•
If there is a risk of colliding with a large
animal, City Safety can reduce the vehi-
cle's speed by up to 9 mph (15 km/h).
Warnings and braking are most effective
at speeds above 43 mph (70 km/h) and
less effective at lower speeds.
WARNING
•
Warnings for stationary or slow-moving
vehicles and large animals may be impe-
ded by darkness or poor visibility.
•
Warnings and braking for pedestrians and
cyclists will not be provided at speeds
above approx. 43 mph (70 km/h).

•
Do not place, attach or mount any objects
on the inside or outside of the windshield
near or over the sensor. This could affect
the camera-based functions.
•
Objects, snow, ice or dirt in the camera's
field of vision may result in certain func-
tions being reduced or disabled, or they
may respond incorrectly.

Rear Collision Warning (RCW)
The
Rear Collision Warning with braking at
standstill
(RCW) function can help the driver
avoid rear-end collisions.
RCW is activated automatically each time the
engine is started.
RCW can warn the driver of a vehicle approach-
ing yours from behind by rapidly flashing your
turn signals.
RCW is only activated when a vehicle is rapidly
approaching your vehicle from behind.
At speeds below 20 mph (30 km/h), if RCW
determines that your vehicle is at risk of a rear-
end collision, the front seat belt pretensioners
and the Whiplash Protection System are acti-
vated.
Just prior to the collision, the brakes are also
applied to help reduce your vehicle's forward
movement if and when the collision occurs. How-
ever, this can only happen if your vehicle is sta-
tionary.
The brakes will be released immediately if the
accelerator pedal is pressed.
•
Due to local traffic regulations in certain
markets, RCW will not activate the rear
turn signals. That part of the function will
be deactivated.
•
The use of the rear turn signals will also
be deactivated if the City Safety warning
level is set at
Later
. See also the section
"Setting a warning level (distance)" in the
article "City Safety settings."
•
If RCW detects a vehicle approaching
from behind, the seat belt pretensioners
and Whiplash Protection System will be
activated.
Limitations
In some circumstances, it may be difficult for
RCW to help the driver if there is a risk of a colli-
sion, such as:
•
If the vehicle approaching from the rear is
detected at a late stage
•
If the vehicle approaching from the rear
changes lanes at a late stage
•
If the vehicle approaching from the rear is
moving at a speed above approx. 50 mph
(80 km/h)

Blind Spot Information (BLIS)
*
Blind Spot Information is a system designed to
alert the driver to the presence of other vehicles
moving in the same direction as your vehicle on
roads with several lanes.
Blind Spot Information is a driving aid intended
to:
•
detect other vehicles in your door mirrors'
"blind area"
•
detect vehicles that are about to pass your
vehicle or are approaching your vehicle
quickly from behind in the left and/or right
lanes
WARNING
•
Blind Spot Information is an information
system, NOT a warning or safety system
and does not function in all situations.
•
Blind Spot Information does not eliminate
the need for you to visually confirm the
conditions around you, and the need for
you to turn your head and shoulders to
make sure that you can safely change
lanes or back up.
•
As the driver, you have full responsibility
for changing lanes/backing up in a safe
manner.
Overview
Blind Spot Information indicators
Indicator light
BLIS button in the center display's Function
view to activate/deactivate the function
The indicator light illuminates on the side of the
vehicle where the system has detected another
vehicle. If your vehicle is passed on both sides at
the same time, both lights will illuminate.
Principle for Blind Spot Information: Zone 1. Blind area,
Zone 2. Area for approaching/passing vehicles
Blind Spot Information functions when your vehi-
cle is moving at speeds above approx. 6 mph
(10 km/h).
Blind Spot Information is designed to react to:
•
vehicles that are passing your vehicle
•
other vehicles that are rapidly approaching
your vehicle
When Blind Spot Information detects a vehicle in
zone 1 or a fast-approaching vehicle in zone 2,
the indicator light in the respective door mirror
will glow steadily.
If the driver then uses the turn signal on the side
on which the warning is given, the indicator light
will begin flashing and become brighter.

Cross Traffic Alert (CTA)
*
Cross Traffic Alert (CTA) is a supplementary part
of Blind Spot Information and is intended to
detect vehicles crossing behind your vehicle
while you are backing up.
When does Cross Traffic Alert function
Principle for CTA
CTA supplements BLIS by warning the driver of
crossing traffic behind your vehicle, for example,
when backing out of a parking space.
It is primarily designed to detect another vehicle
but in certain cases may also detect pedestrians
or smaller objects such as bicycles.
CTA is only activated when the vehicle is rolling
rearward or backing up and is activated automati-
cally when the gear selector is put in reverse.

Cross Traffic Alert (CTA)
* limitations
CTA functionality may be reduced in certain sit-
uations.
Limitations
CTA has limitations in certain situations, for
example, the CTA sensors cannot "see" through
other parked vehicles or obstructions.
The following are several examples where CTA's
"field of vision" may initially be limited and
approaching vehicles cannot be detected until
they are too close:
The vehicle is pulled far into a parking space
In angled parking spaces, CTA may be "blind" on one
side
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a park-
ing space, CTA's "field of vision" expands.
Examples of other limitations include:
•
Dirt, ice or snow obstructing the sensors may
reduce the system's function or make it
impossible to detect other vehicles or
objects.
•
CTA is deactivated if a trailer's wiring is con-
nected to the vehicle's electrical system.
Maintenance
The CTA sensors are located on the inside of the
rear fenders/bumper.
Keep the highlighted area clean (on both sides of the
vehicle)
For the system to function optimally, the area
over and around the sensors must be kept clean.
Do not attach any objects, tape, decals, etc., on
the surface of the sensors.
Repairs to the BLIS/CTA systems and/or
repainting the rear bumper should only be
done by a trained and qualified Volvo service
technician.

Road Sign Information (RSI)
*
RSI is a feature that helps the driver see road
signs showing the posted speed limit.
Examples of readable road signs
If the vehicle passes a sign showing the speed
limit, this will be displayed in the instrument panel
and the head-up display
*.
If the vehicle is equipped with the Sensus
Navigation system, speed-related information
is provided by this system in the following
instances:
•
In cases where the speed limit is given
indirectly (e.g., when driving on highways
or other major roads).
•
If a previously read speed limit sign is no
longer considered valid and no new sign
has been passed.
If a third-party navigation system is being
used, RSI has no support for speed-related
information.
WARNING
RSI does not function in all situations and is
only intended to provide supplementary infor-
mation.
The driver is always responsible for operating
the vehicle safely.

Driver Alert Control (DAC)
DAC is intended to alert the driver if his/her driv-
ing becomes erratic due to e.g., distraction or
fatigue.
DAC is designed to help detect a slowly chang-
ing driving pattern. It is primarily intended to be
used on main roads and is not meant for use in
city traffic.
The function activates initially when the vehicle's
speed first exceeds 40 mph (65 km/h) and
remains active as long the speed remains above
approx. 38 mph (60 km/h)
A camera monitors the traffic lane's side marker
lines and compares the direction of the road with
the driver’s movements of the steering wheel.
7
Speed information is not available in all markets.
DRIVER SUPPORT

If the driving pattern becomes
noticeably erratic, the driver will
be alerted by an audible signal
and
Driver Alert
Time for a
break
will appear in the instru-
ment panel along with a sym-
bol.
The warning will be repeated if the driving pattern
does not change.
WARNING
•
DAC is not intended to extend the dura-
tion of driving. Always plan breaks at reg-
ular intervals to help remain alert.
•
A warning from DAC should not be
ignored. A driver may not be aware of
how fatigued he/she has become.
•
In certain cases, fatigue may not affect
the driver’s behavior. In situations of this
type, no warning will be provided. There-
fore, it is important to take breaks at reg-
ular intervals, regardless of whether or
not DAC has given a warning.

help reduce the risk of accidents in situations
where the vehicle unintentionally leaves its lane
on highways or other major roads.
Driving lane assistance system
Lane Keeping Aid (LKA) actively steers the vehi-
cle to help keep it in its traffic lane and/or alerts
the driver using an audible signal or through
vibrations in the steering wheel.
The driving lane assistance system are active at
speeds between approx. 40-125 mph
(65-200 km/h) on roads with clearly visible traf-
fic lane marker lines. Always observe posted
speed limits.
On narrow roads, the system may not function
and will go into standby mode. It will return to
active mode if the road becomes sufficiently
wide.
A camera monitors the road/traffic lane's marker lines.
