LIGHTING
154Parking lights
The parking lights can be used to help other
road users see the vehicle if it is stopped or
parked. Use the lighting ring on the steering
wheel lever to turn on the parking lights.
Lighting ring in the parking light position.
Turn the lighting ring to the position to
turn on the parking lights (the license plate light-
ing will also illuminate).
Canadian models: If the ignition is in the II posi-
tion or the engine is running, the daytime running
lights will illuminate instead of the front parking
lights. With the lighting ring in this position, the
parking lights will remain on regardless of what
position the ignition is in.
US models: When mode is selected, the
daytime running lights can be deactivated in the
center display. The parking lights will also be deactivated. In weak daylight or dark conditions,
the parking lights and low beams will be illumi-
nated.
In dark conditions, the rear parking lights also
illuminate when the tailgate is opened to alert fol-
lowing traffic. This happens regardless of what
position the lighting ring or ignition is in.

dimming function
Bright light entering the vehicle from behind, e.g.
from the headlights of following vehicles, could
reflect in the rearview mirror and door mirrors
and cause a glare. Use the dimming function
when light from behind is distracting.
Auto-dimIf bright light enters the vehicle from behind, the
door mirrors will automatically dim. Auto-dim is
always active when the engine is running, except
when reverse gear is engaged.
NOTE When the level of sensitivity is changed, this
change will not be noticeable immediately but
will instead take effect after a short period of
time.
The sensitivity level for dimming will affect both
the rearview mirror and door mirrors.

Normal, Dark or Light.
The rearview mirror instead has two sensors -
one pointing forward and one pointing rearward -
which work together to identify and eliminate glare. The forward-pointing sensor monitors
ambient light, while the rearward-pointing sensor
monitors light from the headlights of following
vehicles.
For the door mirrors to be equipped with auto-
dim, the rearview mirror must also be equipped
with auto-dim.
NOTE
If the sensors are obstructed by e.g. a parking
permit, transponder, sunshade or objects on
the seats or in the cargo compartment in a
way that prevents light from reaching the sen-
sors, the auto-dim function in the door and
rearview mirrors will be reduced.

CLIMATE CONTROL
* Option/accessory.
202 Climate
The vehicle is equipped with electronic climate
control. The climate system cools, heats and
dehumidifies the air in the passenger compart-
ment. All of the climate system functions are controlled
from the center display and the buttons on the
center console.
Certain rear seat functions can also be controlled
from the climate controls* on the rear of the tun-
nel console.

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
88
graphic 89
on the
screen.
WARNING •
The Cross Traffic Alert function is supple-
mentary driver support intended to facili-
tate driving and make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
• The responsibility for reversing the vehicle
safely and using good judgment always
rests with the driver.
• Cross Traffic Alert 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 appropri-
ate distance to other vehicles, and in
accordance with current traffic rules and
regulations.

CTA 91
functionality may be reduced in certain
situations.
CTA does not function optimally in all situations
and has certain limitations. The CTA sensors, for
example, cannot "see" through other parked
vehicles or objects blocking the vehicle.
Below are a few examples of situations in which
CTA's field of vision may be initially limited and
approaching vehicles may therefore not be
detected until they are very close to your vehicle: The vehicle is parked very far into a parking space. In a diagonal parking space, CTA may be completely
"blind" on one side of your vehicle.

However, as you back your vehicle slowly out of a
parking space, CTA's field of vision changes in
relation to the obstructing vehicle/object and its

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.

DRIVER SUPPORT
382Park Assist front, rear and sides
Park Assist has different parameters depending
on which part of the vehicle is approaching an
obstacle.
Back Note: This illustration is general and details may vary
depending on model.
The rear sensors will be activated if the vehicle
begins rolling backward or if reverse gear is
engaged.
The distance monitored begins
approx. 1.5 meters (5 feet) behind the vehicle.
The rear sensors will be automatically deactivated
if the vehicle is backing up with a trailer attached.
NOTE When reversing with e.g. a trailer or bike car-
rier on the trailer hitch – without Volvo original
trailer cables – the Parking Assist system may
have to be turned off manually to prevent the
sensors from reacting to these.
Side sensors
Park Assist's side sensors are automatically acti-
vated when the engine is started. They are active
at speeds below 10 km/h (6 mph).
The distance monitored begins approx. 30 cm
(1 ft) from the sides. The audible signal for obsta-
cles along the sides of the vehicle is emitted
from the side speakers.
Front camera Note: This illustration is general and details may vary
depending on model.
Park Assist's front sensors are automatically acti-
vated when the engine is started. The front sen-
sors are active at speeds below 10 km/h
(6 mph).
The distance monitored begins approx. 80 cm
(2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivated
when the parking brake is applied or when P
is selected on vehicles with automatic trans-
mission.

Park Assist may not be able to detect all condi-
tions in all situations and functionality may there-
fore be limited in certain cases.
The driver should be aware of the following limi-
tations for Park Assist:
WARNING Be extra cautious when
reversing if this symbol is
shown when a trailer, bike
carrier or similar is attached
and electrically connected
to the vehicle.
The symbol indicates that
the rear parking assist sensors are deacti-
vated and will not warn of any obstacles.

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.
