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

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 345.
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 131 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.
If desired, air distribution can be controlled
manually, see page 144.

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
131 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

General information
Economical driving conserves natural
resources
Better driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions.
Observe the following rules:
•Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•Drive carefully and avoid rapid acceleration
and hard braking.
•Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•Using the transmission's Sport mode1 may
increase fuel consumption somewhat. Use
the transmission's Drive (D) position as
often as possible. See page 116 for addi-
tional information about Sport mode.
•Do not exceed posted speed limits.
•Avoid carrying unnecessary items (extra
load) in the vehicle.
•Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•Remove snow tires when threat of snow or
ice has ended.
•Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
•At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•Dirty air cleaner
•Dirty engine oil and clogged oil filter
•Dragging brakes
•Incorrect front end alignment
Some of the above mentioned items and others
are checked at the standard maintenance
intervals.
WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the tailgate must be kept open
for any reason, proceed as follows:
•Close the windows
•Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend. This ensures good stability and reduces
the risk of rear wheel skid. Remember that
these properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.
Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See the
"Tire pressure" section. Loads should be dis-
1Models with the T6 turbo engine only.
