Introduction
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 1.7 lbs (770 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

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.
Menu settingsThe default settings for three of the climate
system's functions can be changed in the
menu system, see page 124:
•Blower speed in automatic mode, see
page 131.
•Recirculation timer for passenger com-
partment air, see page 133.
•Automatic rear window defrosting, see
page 100.
The functions can also be returned to factory
settings in the menu system.
Air distribution
G017699
The incoming air is distributed from 20 different
vents in the passenger compartment.Air distribution is fully automatic in AUTO
mode.
If desired, air distribution can be controlled
manually, see page 134.

dows.
Temperature controlThe temperatures on the
driver and passenger sides
can be set independently.
When the vehicle is started,
the most recent setting is
resumed.
NOTE
Heating or cooling cannot be speeded up by
selecting a higher/lower temperature than
the actual temperature required.
A/C – ON/OFFThe air conditioning is con-
trolled automatically by the
system when the ON light is
on. This cools/heats and
dehumidifies the incoming air.
When the OFF light is on, the
air conditioning is always dis-
engaged. Other functions are still controlled
automatically. When defroster is selected, the
air conditioning system 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

Collision warning with Auto-brake*
04

* Option/accessory, for more information, see Introduction.177
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 175). This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
The camera’s limitationsThe camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 180), and Lane Departure Warning (see
page 183).
NOTE
•To help protect the camera in very hot
conditions, it may be temporarily
switched off for approximately 15
minutes after the engine has been
started.
•Keep the section of the windshield in
front of the camera clean and free of ice,
snow, or condensation.
WARNING
•The camera has the same limitations as
the human eye. In other words, its
“vision is impaired” by adverse weather
conditions such as heavy snowfall,
dense fog, etc. These conditions may
reduce the function of systems that
depend on the camera or cause these
systems to temporarily stop function-
ing.
•Never place any objects, decals, etc.,
on the windshield in front of the camera.
This could reduce or block the camera’s
function, and could cause one or more
of the systems that utilize the camera to
stop functioning.
•Strong sunlight, reflections from the
road surface, ice or snow covering the
road, a dirty road surface, or unclear
lane marker lines may drastically reduce
the camera’s capacity to detect the side
of a lane or another vehicle.
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the cam-
era is obscured and cannot detect vehicles or
road marker lines in front of the vehicle.
This, in turn, means that Collision Warning with
Auto-brake, Lane Departure Warning, and
Driver Alert Control will not have full function-
ality.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.

192* Option/accessory, for more information, see Introduction.
Introduction
G021426
BLIS camera
Indicator light
BLIS symbol
The Blind Spot Information System (BLIS) is an
information system that indicates the presence
of another vehicle moving in the same direction
as your vehicle in the side-view mirror's "blind
area."
CAUTION
The BLIS system should only be repaired by
a trained and qualified Volvo service tech-
nician.
WARNING
•BLIS is an information system, NOT a
warning or safety system.
•BLIS 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.
•As the driver, you have full responsibility
for changing lanes in a safe manner.
The system is based on digital camera tech-
nology. The cameras are located beneath the
side-view mirrors.
When one (or both) of the cameras have
detected a vehicle in the blind area (up to
approximately 10 ft. (3 meters) from the side of
your vehicle, and up to approximately 31 ft.
(9.5 meters) behind the side-view mirror), see
the illustration, the indicator light in the door
panel illuminates. The light will glow continu-
ously to alert the driver of the vehicle in the
blind area.
NOTE
The door panel 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.
BLIS has an integrated function that alerts the
driver if a fault should occur with the system.
For example, if one or both of the system's
cameras are obscured, a message (see the
table on page 194) will appear in the informa-
tion display in the instrument panel. If this
occurs, clean the camera lenses. If necessary,
the system can be temporarily switched off (for
instructions, see page 194).
Areas monitored by BLIS Distance A = approx.
31 ft. (9.5 meters), Distance B = approx. 10 ft.
(3 meters)

* Option/accessory, for more information, see Introduction.193 When does BLIS function
The system functions when your vehicle is
moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:The system reacts when you pass another
vehicle at a speed of up to 6 mph (10 km/h)
faster than that vehicle.
When you are passed by another vehicle:The system reacts if your vehicle is passed by
another vehicle at a speed of up to 43 mph
(70 km/h) faster than your vehicle.
WARNING
•BLIS does not function in sharp curves.
•BLIS does not function when your vehi-
cle is backing up.
•If you are towing a wide trailer, this may
prevent the BLIS cameras from detect-
ing other vehicles in adjacent lanes.
How BLIS functions in daylight and
darkness
Daylight
BLIS reacts to the shape of surrounding vehi-
cles. The system is designed to help detect
motor vehicles such as cars, trucks, buses,
motorcycles, etc.
DarknessBLIS reacts to the headlights of surrounding
vehicles. In order to be detected by BLIS, a
vehicle in the blind area must have its head-
lights on. This means, for example, that the
system will not detect a trailer without head-
lights that is being towed behind a car or truck.
WARNING
•BLIS does not react to cyclists or
mopeds.
•BLIS does not react to vehicles that are
standing still.
•The BLIS cameras have the same limi-
tation as the human eye. In other words,
their "vision is impaired" by adverse
weather conditions such as heavy
snowfall, intense light directly into the
camera, dense fog, etc.
LimitationsIn certain situations, the BLIS indicator light(s)
may illuminate even when there are no other
vehicles in the area monitored by the system.
NOTE
If the BLIS indicator lights illuminate occa-
sionally even when there are no other vehi-
cles in the blind area, this does not indicate
a fault in the system.
In the event of a fault,
Blind spot syst.
Service required will be displayed.
The following are several examples of situa-
tions in which the BLIS indicator light(s) may
illuminate even when there are no other vehi-
cles in the area monitored by the system.
