* Option/accessory, for more information, see Introduction.173 Signals from the park assist system
View in the display (warning for objects front left/
right rear)
Visual indicatorThe audio system’s display gives an overview
of the vehicle’s position in relation to a
detected object.
The marked sectors in the display indicate that
one or more of the sensors has detected an
object. The closer the car symbol comes to a
sector, the closer the vehicle is to the object.
If the infotainment system is switched off, the
park assist system will not be able to provide a
visual indicator. An audible signal will still be
provided.
Audible signalThe Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
in front of or behind the vehicle. If there are
objects within this distance both behind and in
front of the vehicle, the tone alternates
between front and rear speakers.
NOTE
The level of the audible signal can be low-
ered/raised with the infotainment volume
control. The level can also be set in the MY
CAR menu system. See page 189 for a
description of the menu system.
If the volume of another source from the audio
system is high, this will be automatically low-
ered.
Rear park assist
G017833
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The audible signal
comes from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.

Front park assist
G021424
The distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system's front
speakers.
It may not be possible to combine auxiliary
headlights and front park assist since these
lights could trigger the system's sensors.
NOTE
Front park assist is deactivated when the
parking brake is applied and or when the
gear selector is in the P position.
Faults in the system
If the information symbol illuminates and Park
assist syst Service required is shown on the
information display, this indicates that the sys-
tem is not functioning properly and has been
disengaged. Consult a trained and qualified
Volvo service technician.
CAUTION
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.
Cleaning the sensors
Location of the front sensors
Location of the rear sensors
The sensors must be cleaned regularly to
ensure that they work properly. Clean them

with water and a suitable car washing deter-
gent.
Ice and snow covering the sensors may cause
incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warn-
ing signals from the park assist system.

"Wheel tracks"
The solid line (1) indicates a zone within 1 ft
(30 centimeters) of the rear bumper.The dashed line (2) indicates the clear zone of
approximately 5 feet (1.5 m) behind the
bumper. These lines also indicate the outmost
limits that any object (door mirrors, corners of
the body, etc.) extends out from the vehicle,
even when it turns.
The "wheel tracks" (3) between the side marker
lines show where the wheels will roll and can
extend up to approximately 10.5 ft (3.2 m)
behind the bumper if there are no objects in the
way.
Vehicles equipped with Park Assist
Colored fields (4-one per sensor) indicate distance
If the vehicle is equipped with the optional Park
Assist system, the distance to an object will be
indicated more exactly and colored markers in
the display indicate which of the sensor(s) has
detected the object.The markers change color (from yellow to
orange to red) as the vehicle comes closer to
the object.

image is shown on the center console dis-
play.
•When backing up, two solid lines are pro-
jected on the screen to show the path that
the vehicle's rear wheels will take. These
lines are affected by movements of the
steering wheel. The vehicle's approximate
outer dimension are shown by two dashed
lines.
•The graphic lines will not be displayed
when backing up with a trailer that is con-
nected to the vehicle's electrical system.
•Objects on the ground that are closer than
1 ft (30 centimeters) cannot be detected by
the camera.
•The camera is active for approx.
5 seconds after the gear selector is moved
to R or until the vehicle's speed exceeds
6 mph (10 km/h).
•The optional Park Assist sensors and the
parking camera work together and infor-
mation from the sensors is shown graphi-
cally on the display.
•The graphic lines shown on the screen
when the vehicle backs up can be disabled
in the settings menu.
•Manual zoom can be selected in the MY
CAR menu.
•The system can be switched off by press-
ing CAM. By default, the system is acti-
vated when the gear selector is moved toR. This setting can be changed in the MY

•If there are two cameras installed on the
vehicle*, to switch between cameras, turn
TUNE (at least one of the cameras has to
be active), press CAM repeatedly or use
the center console controls. If the front
camera is on, it overrides the optional park
assist system's visual indicator but there
will still be an audible signal.
Limitations
Even if a fairly small section of the screen image
appears to be obstructed, this may mean that
a relatively large area behind the vehicle is hid-
den and objects there may not be detected
until they are very near the vehicle.
NOTE
Bicycle carriers or other accessories moun-
ted on the tailgate may obstruct the cam-
era's field of view.
Keep in mind
•Keep the camera's lens free of dirt, ice and
snow. Remove ice and snow carefully to
avoid scratching the lens.
•Clean the lens regularly with warm water
and a suitable car washing detergent.

Air conditioningThe vehicle is equipped with Electronic Climate
Control (ECC). The climate control system
cools, heats or dehumidifies the air in the pas-
senger compartment.
NOTE
•The air conditioning can be switched
off, but to ensure the best possible cli-
mate comfort in the passenger com-
partment and to prevent the windows
from misting, it should always be on.
•In warm weather, a small amount of
water may accumulate under the car
when it has been parked. This water is
condensation from the A/C system and
is normal.
Sensor location
•The sunlight sensor is located on the top
side of the dashboard.
NOTE
The sunlight sensor monitors which side of
the car that is most exposed to sunlight.
This can mean that the temperature may
differ between the right and left-side air
vents, even if the temperatures set for both
sides of the passenger compartment are the
same.
•The temperature sensor for the passenger
compartment is located below the climate
control panel.
•The outside (ambient) temperature sensor
is located on the door mirror.
•The humidity sensor* is located in the inte-
rior rearview mirror.
NOTE
Do not cover or block the sensors with
clothing or other objects.
Side windows and moonroofTo ensure that the air conditioning works opti-
mally, the side windows, and the optional
moonroof should be closed.
Fog on the inside of the windowsThe defroster function should be used to
remove fog or mist from the inside of the win-
dows. Keeping the windows clean with a com-mercially available window washing spray will
also help prevent fogging or misting.
Temporary shut-off of the air
conditioning
The air conditioning is momentarily disen-
gaged during full-throttle acceleration or when
driving uphill with a trailer. This may result in a
temporary increase in cabin temperature.
Ice and snowAlways keep the air intake grille at the base of
the windshield free of snow.
Climate system maintenanceSpecial tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.
RefrigerantVolvo cares about the environment. The air
conditioning system in your car contains a
CFC-free refrigerant – R134a. This substance
will not deplete the ozone layer. The air condi-
tioning system contains 1.8 lbs (820 g) of
R134a. The systems uses PAG oil.
Passenger compartment filterReplace the cabin air filter with a new one at
the recommended intervals. Please refer to

05 Comfort and driving pleasure

your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
NOTE
There are different types of cabin air filters.
Ensure that the correct type is installed.
Interior Air Quality System (IAQS)A multifilter helps reduce gases and particles
in the incoming air, thereby reducing the levels
of odors and contaminants entering the vehi-
cle. The air quality sensor detects increased
levels of contaminants in the outside air. When
the air quality sensor detects contaminated
outside air, the air intake closes and the air
inside the passenger compartment is recircu-
lated, i.e. no outside air enters the vehicle. The
filter also cleans recirculated passenger com-
partment air.
NOTE
Contact your Volvo retailer for IAQS air filter
replacement intervals.
Materials used in the cabinThe materials used in the cabin have been
developed to help minimize the amount of dust
and make the cabin easier to keep clean. All
floor mats can be easily removed for cleaning.
Use car cleaning products recommended by
Volvo. See also the information beginning on
page 351.
Menu settingsThe default settings for four of the climate sys-
tem's functions can be changed in the menu
system.
•Blower speed in automatic mode.
•Recirculation timer for passenger com-
partment air.
•Automatic rear window defrosting.
•The optional Interior Air Quality System
(IAQS).
The functions can also be returned to factory
settings in the menu system.
See page 189 for a description of the menu
system.
Air distribution
G017699
The incoming air is distributed from a number
of different vents in the passenger compart-
ment.
Air distribution is fully automatic in AUTO
mode.

A/C – ON/OFFWhen the indicator light in the
button is on, the air condition-
ing is controlled automati-
cally. This cools/heats and
dehumidifies the incoming air.
When the indicator light in the
button is off, the air condition-
ing is disengaged. Other functions are still con-
trolled automatically. When maximum
defroster is selected, the air conditioning sys-
tem is set for maximum blower speed and
dehumidification.
DefrosterThis function defrosts/de-ices
the windshield and front side
windows. The indicator light
in the defroster button lights
when the function is active.
•Blower speed increases automatically and
the air conditioning will switch on (if not
already on and if the passenger compart-
ment blower is not turned off) to dehumid-
ify the air in the passenger compartment.
Air conditioning can be switched off by
pressing the AC button.
•Recirculation will not function while defrost
is engaged.The climate system will return to its previous
settings when the defroster function is
switched off.
Recirculation/air quality system
Recirculation
This function can be used to
shut out exhaust fumes,
smoke, etc., from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e., no air
from outside the car is taken
into the car when this function is activated. The
indicator light in the button will illuminate when
recirculation is selected.
If the air in the car recirculates for too long,
there is a risk of condensation forming on the
insides of the windows, especially in winter.
TimerThe timer function minimizes the risk of fog-
ging, or stale air when the recirculation function
is selected by automatically switching off the
function after a certain length of time, depend-
ing on the ambient temperature. Activate/
deactivate the function under Climate
settings
Recirculation timer. See page
189 for a description of the menu system.
NOTE
When Defroster is selected, recirculation is
always deactivated.
Interior Air Quality System–IAQS*This system consists of a multifilter and an air
quality sensor. The filter helps remove gases
and particles from the incoming air, thereby
reducing the amounts of odors and contami-
nants entering the vehicle. The air quality sen-
sor detects increased levels of contaminants in
the outside air. When the air quality sensor
detects contaminated outside air, the air intake
closes and the air inside the passenger com-
partment is recirculated, i.e., no outside air
enters the vehicle. The filter also cleans recir-
culated passenger compartment air. When the
AUTO button is depressed the air quality sen-
sor is always engaged.
Activate or deactivate this function in Climate
settings

NOTE
•The air quality sensor should always be
engaged in order to obtain the best air
in the passenger compartment.
•Recirculation is limited in cold weather
to avoid fogging.
•If the insides of the windows start fog-
ging, disengage the air quality sensor.
Use the defroster function to increase
airflow to the front, side, and rear win-
dows.
