IntroductionAir 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 temperature sensor is located
on the door mirror.
•
The humidity sensor (option) is located in
the interior 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
conditioningThe 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 (800 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 120:•
Blower speed in automatic mode, see
page 127.
•
Recirculation timer for passenger com-
partment air, see page 127.
•
Automatic rear window defrosting, see
page 97.
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 130.

Stability system
04``155 Introduction
The Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed help reduce wheel spin, coun-
teract skidding, and to generally help improve
directional stability.
CAUTION
A pulsating sound will be audible when the
system is actively operating and is normal.Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and
cannot be switched off.Active Yaw Control (AYC)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
This is one of DSTC's permanent functions and
cannot be switched off.
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
WARNING
The car's handling and stability characteris-
tics will be altered if the spin control function
has been disabled.Operation
