Recommended maintenance for the
camera/radar sensor
In order for the camera/radar sensor to function
properly, the area of the windshield in front of the
unit must be kept free of dirt, ice, snow, etc. and
should be washed regularly with water and car
washing detergent.
NOTE
Dirt, ice and snow covering the camera and
radar unit reduce their function and can make
measurement impossible.
It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.

Camera (p. 331) City Safety™
City Safety can alert the driver with light, sound
and pulsations in the brake pedal to help the
driver detect pedestrians, cyclists, large animals
and vehicles that appear suddenly – the vehicle
will then attempt to automatically brake if the
driver does not act within a reasonable amount
of time. Location of the camera and radar sensor
75
.
City Safety can help prevent a collision or lower
the vehicle's speed at the point of impact.
City Safety is an aid intended to assist the driver
if a collision with a pedestrian, large animal,
cyclist or vehicle is imminent.
City Safety can help the driver avoid a collision
when e.g. driving in stop-and-go traffic, when changes in the traffic ahead and driver distraction
could lead to an incident.
The function assists the driver by automatically
applying the brakes if there is an imminent risk of
a collision and the driver does not react in time by
braking and/or steering away.
City Safety activates a brief, forceful braking in an
attempt to stop your vehicle immediately behind
the vehicle or object ahead.
City Safety is activated in situations in which the
driver should have applied the brakes much ear-
lier, which means that the system will not be able
to assist the driver in all situations.
City Safety is designed to be activated as late as
possible to help avoid unnecessary intervention.
Normally, the occupants of the vehicle will not be
aware of City Safety except when the system
intervenes when a collision is imminent.

344City Safety limitations
City Safety functionality may be reduced in cer-
tain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhanging
loads or accessories such as auxiliary lights or
front protective grids that extend beyond the
height of the hood, may limit City Safety function-
ality.
Slippery road conditions
The extended braking distance on slippery roads
may reduce City Safety's capacity to help avoid a
collision. In these types of situations, the Anti-
lock Braking System and Electronic Stability Con-
trol (ESC 77
) will help provide optimal braking
power with maintained stability.
Backlighting
The visual warning signal in the windshield may
be difficult to detect in bright sunlight, if there are
reflections, or if the driver is wearing sunglasses
or not looking straight ahead.
Heat
If the temperature in the passenger compartment
is high due to e.g. bright sunlight, the visual warn-
ing signal in the windshield may be temporarily
disabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer-
tain situations, it may be unable to detect pedes-
trians, large animals, cyclists or vehicles, or it may
detect them later than expected.
Vehicles that are dirty may be detected later than
clean vehicles, and in dark conditions, motorcy-
cles may be detected late or not at all.
If a text message displayed in the instrument
panel indicates that the camera/radar sensor is
obstructed, it may be difficult for City Safety to
detect pedestrians, large animals, cyclists, vehi-
cles or lane markings in front of the vehicle. City
Safety functionality may therefore be reduced.
Text messages may not be displayed for all situa-
tions in which the windshield sensors are
blocked. The driver must therefore always keep
the windshield in front of the camera/radar sen-
sor clean.
CAUTION Maintenance and replacement of City Safety
components may only be performed by a
workshop – an authorized Volvo workshop is
recommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when the
vehicle is backing up.
Low speed
City Safety is not activated at very low speeds
under 4 km/h (3 mph). The system will therefore
not intervene in situations in which your vehicle is
approaching another vehicle very slowly, such as
when parking.
Active driver
Action by the driver always has priority. City
Safety will therefore not react or will react at a
later stage with a warning or intervention in situa-
tions in which the driver is clearly steering and
operating the accelerator pedal, even if a collision
is unavoidable.
An active and aware driving style may therefore
delay collision warnings and intervention in order
to minimize unnecessary warnings.

Cross Traffic Alert*
CTA 86
is a supplementary driver support system
to BLIS 87
that is intended to help the driver
detect vehicles crossing behind the vehicle
while backing up. CTA overview.
CTA supplements BLIS by detecting traffic cross-
ing from the side, e.g. when backing out of a
parking space.
CTA is primarily designed to detect vehicles, but
in certain cases can also detect pedestrians or
smaller objects such as bicycles.
CTA is only active when the vehicle is moving
backward or if reverse gear is engaged. If CTA detects that something is approaching
your vehicle from the side:
• an audible signal will sound from either the
left or right speaker, depending on which
side of your vehicle the object is approaching
from.
• an icon will illuminate in the PAS 88
graphic
on the screen.
• an icon will appear in the Park Assist Cam-
era's Top view. Illuminated CTA icon in the PAS

DRIVER SUPPORT
* Option/accessory.381
Park Assist*
The Park Assist function can help the driver
when maneuvering in tight spaces by indicating
distances to obstacles using audible signals and
graphics in the center display. Display view showing obstacle zones and sensor sec-
tors.
The center display shows an overview of the vehi-
cle in relation to objects that have been detected.
The marked sector indicates where the obstacle
is located. The closer the vehicle symbol is to a
marked sector, the closer the detected obstacle
is to your vehicle.
The audible signals will also speed up the closer
the obstacle is to the vehicle. The volume of the
audio system will be automatically lowered.
Audible signals for obstacles in front and to the
sides of the vehicle are active when the vehicle is moving but will cease after the vehicle has been
stationary for approx. 2 seconds. Audible signals
for obstacles behind the vehicle will remain active
even when the vehicle is stationary.
If a detected obstacle is within 30 cm (1 ft) from
the front or rear of the vehicle, the tone will
become constant and the active sensor's field
closest to the vehicle symbol will be filled in.
The volume of the Park Assist audible signals
can be adjusted while the signal is being given
using the >II knob or in the center display's Top
view under Settings.
NOTE •
Acoustic warnings are only given for
objects directly in front of the vehicle's
path.
WARNING •
The Parking Assist function is supple-
mentary driver support intended to facili-
tate driving and help make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.
• The parking sensors have dead/blind
spots where objects cannot be detected.
• Pay particular attention to people and
animals near the vehicle.
• Parking Assist is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

CAUTION Objects such as chains, thin and glossy poles
or low obstacles may end up in the "signal
shadow" and then go temporarily undetected
by the sensors – the pulsating tone may then
unexpectedly stop instead of becoming a
constant tone as expected.
The sensors cannot detect high objects, such
as protruding ramps.
• In such situations, pay extra attention and
maneuver/drive the vehicle very slowly or
stop the current parking maneuver –
there may be a high risk of damage to
the vehicle or other objects since infor-
mation from the sensors is not always
reliable in such situations.
CAUTION In some circumstances, the Park Assist Sys-
tem may produce false warnings due to exter-
nal sound sources with the same ultrasonic
frequencies as those the system works with.
Examples of such sources are horns, wet tires
on asphalt, pneumatic brakes, exhaust noise
from motorcycles, etc.
NOTE When a trailer hitch is configured with the
vehicle electrical system, the trailer hitch pro-
trusion is included when the function meas-
ures the distance to objects behind the vehi-
cle.
