Condensation on the inside of the
windows
Keeping the insides of the windows clean will
help reduce the amount of condensation that
forms on the windows. Use a commercial win-
dow cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of
the windshield free of snow.
Cabin air filter
Replace 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.
Sensors
The sunlight sensor on the dashboard and pas-
senger compartment temperature sensor in
the ECC control panel should not be covered
in any way as this could cause incorrect infor-
mation to be sent to the ECC system.
Parking the vehicle in warm weather
If your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof* for several minutes before driving
will help release the warm air from the passen-
ger compartment. When the engine is running,
close the windows and moonroof and use the
recirculation function for several minutes to
enable the air conditioning to cool the com-
partment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the win-
dows and optional moonroof are closed. If you
drive with the moonroof open, we recommend
that you manually adjust the temperature and
blower control (the LED in the AUTO switch
should be off).
Acceleration
The air conditioning is momentarily disen-
gaged during full-throttle acceleration.
Climate control maintenance
Special 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.
Refrigerant
Volvo cares about the environment. The air
conditioning system in your vehicle contains a
CFC-free refrigerant – R134a (HFC134a). This
substance will not deplete the ozone layer. The
approximate amount of R134a contained in the
system is a follows:
6-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual
1 A/C system: 2.2 lbs (1000 g)
The system also uses PAG oil.

95 Climate system blower
The climate system blower will be automati-
cally switched off when the engine is not run-
ning (even if the ignition key is in position I or
II) to avoid unnecessary battery drain. To acti-
vate the blower, turn the control to the desired
setting.
The climate system blower may start automat-
ically during a period of up to approximately
50 minutes after the ignition has been turned
off to remove condensation in the A/C evapo-
rator. It will run for 15 minutes and switch off
automatically.
Passenger compartment blower
Approximately 50 minutes after the ignition is
turned off, the blower may come on automati-
cally, and run for seven minutes, to remove
condensation in the A/C evaporator.
Blower function to reduce battery drain
The climate system's blower functions nor-
mally while the engine is running.
However, when the engine is switched off
(even if the ignition is switched to positions I or
II), the blower control will be automatically
switched off to avoid unnecessary battery
drain.The following points pertain if the ignition is on
but the engine in not running:
•To restart the blower, turn the control knob
to the setting of your choice.
•After approximately 2 minutes, the blower
speed will be reduced to avoid battery
drain.
You can reset the blower speed at any time.
Please be aware that the system has been
designed to reduce the blower's speed again
after 2 minutes, until the engine is started.
If the battery becomes drained:
•LOW BATTERY, FAN IS REDUCED will
be displayed in the text window in the
instrument panel.
•The yellow warning light in the instrument
panel (see page 58) will also light up.

* Option/accessory, for more information, see Introduction.97 Ventilated front seats*
G030244
Controls for ventilated front seats
The ventilation system consists of fans in the
seats and backrests that draw air through the
seat upholstery. The cooling effect increases
as the air in the passenger compartment
becomes cooler.
The level of ventilation is adjusted on the con-
trol panel on the side of the seat. The fans can
be set to three speeds.
To start seat ventilation:

Press briefly on
.
To gradually increase ventilation:

Press briefly on
.For maximum ventilation:

Hold down
for approximately 2 sec-
onds.
To gradually decrease ventilation:

Press briefly on
.
To switch off ventilation:

Hold down
for approximately 2 sec-
onds.
The ventilation can be used at the same time
as seat heating*, for example, to help dry damp
clothing.
NOTE
•Seat ventilation cannot be started if the
temperature in the passenger compart-
ment is below 41°F (5°C).
•Seat ventilation should be used with
caution by people who are sensitive to
drafts. A moderate ventilation level
should be set if the function is used for
extended periods.

Functions
A/C – ON/OFF
•The air conditioning functions only at tem-
peratures above 32°F (0°C).
•While the Defroster function is selected,
the air conditioning is temporarily activated
to dehumidify the air, even if you have man-
ually switched the air conditioning off. Thiswill only function if the blower is not
switched off.
Press the switch to turn the air conditioning on
or off. The "ON" or "OFF" LED will light up to
indicate if the system is switched on or off.
Other functions will still be regulated automat-
ically (if the AUTO switch is on).
Interior air quality sensor*
Some vehicles are equipped with a multifilter
and air quality sensor. The filter separates
gases and particles, thereby reducing the
amounts of odors and contaminants entering
the vehicle. The air quality sensor detects
increased levels of contaminants in the outside
air. When the air quality sensor detects conta-

minated outside air, the air intake closes and
the air inside the passenger compartment is
recirculated, i.e. no outside air enters the vehi-
cle. The filter also cleans recirculated passen-
ger compartment air.
When the ECC system is in the AUTO mode,
the green LED will be on.
Recirculation
Press this switch to engage the recirculation
function (air in the passenger compartment
recirculates – no fresh air enters the compart-
ment). The LED in the switch will light up to
indicate that the function is engaged.
•Use this function if the outside air is con-
taminated with exhaust gases, smoke, etc
or to heat/cool the vehicle quickly.
•Recirculation should not be used for more
than 15 minutes. If your windows begin to
fog or mist, make sure that the recirculation
function is switched off.
•Selecting Defroster automatically
switches recirculation off.
•Timer mode activation: (Vehicles equipped
with the Interior Air Quality system have no
timer mode) Press and hold the recircula-
tion button for at least 3 seconds to acti-
vate a recirculation timer mode. The amber
LED in the recirculation button will flash 5
times to show that the timer mode is being
activated. In timer mode, each time therecirculation button is pressed, the climate
control system will recirculate the air in the
passenger compartment for
5 – 12 minutes, depending on the outside
air temperature, and then revert back to
fresh air.
•Timer mode deactivation: Press and hold
the recirculation button for 3 seconds. The
amber LED in the recirculation button will
illuminate steadily for 5 seconds to show a
return to "normal" mode.
•In normal mode, when the recirculation
button is pressed, the climate control sys-
tem will recirculate the air in the passenger
compartment until the recirculation button
is pressed again.
•Timer mode memory: If the vehicle is
turned off while timer mode is active, timer
mode will still be active when the vehicle is
restarted.
AUTO
This function automatically regulates the
Electronic Climate Control system so that
the selected temperatures are maintained.
The blower, heating, air distribution (air
flow), air conditioning, and optional air qual-
ity sensor are controlled. If you prefer to man-
ually set any of these functions, the remaining
functions will still be controlled automatically.
Pressing the AUTO button overrides any set-
tings that were previously made manually.
Air distribution
G027267
•Air flow to windows
•Air through panel vents
•Air through floor vents
Press AUTO to automatically regulate air flow
or press any combination of the controls
shown in the illustration to manually adjust air
flow. An LED in the switch will light up if an air
flow control has been pressed.
Passenger compartment temperature

Measures the temperature in the compart-
ment.
Defroster

and front side windows. The LED in the switch
