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 window
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 Information booklet, or consult your Volvo retailer 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 passenger compartment
temperature sensor in the ECC control panel should not be covered in
any way as this could cause incorrect information to be sent to the ECC
system.
Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the
windows and moonroof (option) for several minutes before driving will
help release the warm air from the passenger 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 compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the windows 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 disengaged during full-throttle
acceleration.
ECC maintenance
All maintenance on the climate control systems should be carried out by
an authorized Volvo service technician only.
Refrigerant
Volvo 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 system contains 2.2 lbs (1000 g) R134a and
uses PAG oil.
Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower
may come on automatically, and run for five minutes, to remove
condensation in the A/C evaporator.

AUTO
This function automatically regulates the
Electronic Climate Control system so that the
selected temperatures are maintained. The
blower, heating, air distribution (air flow) and
air conditioning are controlled. If you prefer to
manually set any of these functions, the remaining functions will still be
controlled automatically. Pressing the AUTO button overrides any
settings that were previously made manually.
Temperature
These controls are used to individually set the
temperature for both sides of the passenger
compartment. Please note that the compartment
will not be heated or cooled faster by setting the
temperature higher or lower than necessary.
Set the control to the temperature you prefer.
Defroster
This function demists/de-ices the windshield and
front side windows. The LED in the switch will
light up to indicate that the defrost function is
engaged. Blower speed increases automatically
and the air in the passenger compartment is
dehumidified. Recirculation will not function while defrost is engaged.
Heated rear window/sideview
mirrors
This function demists/de-ices the rear window
and sideview mirrors. The LED in the switch will
light up to indicate that the heating function is
engaged. See page 38 for additional information on this function.
CAUTION:
Never use ice scrapers made of metal as they can easily scratch the
mirror surface.

Recirculation (see also page 48)
Press this switch to engage the recirculation
function (air in the passenger compartment
recirculates - no fresh air enters the compartment).
The LED in the switch will light up to
indicate that the function is engaged.
Use this function if the outside air is contaminated with exhaust
gases, smoke, etc or to heat/cool the car 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: (Cars with Interior Air Quality system have no
timer mode) Press and hold the recirculation button for at least 3 seconds
to activate 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 the timer mode, each time the recirculation button is pressed, the climate control system will recirculate the air in the passenger compartment for 5-12 minutes, depending on the outside air and then revert back to fresh air.
Timer mode deactivation: Press and hold the recirculation button for at least 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 system will recirculate the air in the passenger compartment until the recirculation button is pressed again.
Timer mode memory: If the car is turned off while timer mode is active, timer mode will still be active when the car is restarted.
Heated front seats (option)
Please see page 38 for more information on this
function.
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.
Air conditioning ON/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 automatically (if
the AUTO switch is on).
The air conditioning functions only at temperatures 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
manually switched the air conditioning off. This will only function if
the blower is not switched off.
Blower control
Turn the control clockwise to increase or
counterclockwise to decrease the blower speed.
Pressing the AUTO switch will automatically
regulate blower speed and override manual
adjustment.
NOTE: Turning the blower control counterclockwise as far as possible
(an orange LED next to the control will light up) will turn both the
blower and the air conditioning off.

Interior Air Quality system
(option)
Some cars 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 car. 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 recirculated, i.e. no
outside air enters the car. The filter also cleans
recirculated passenger compartment air.
When the Air quality sensor is activated, the
LED AUT comes on in 
Operation:
Press 
to activate the Air quality sensor
(normal setting).
Or select one of three functions by pressing
.
1. Press
: the LED AUT comes on.
The Air quality sensor is now activated.
2. Press
: no LED is lighted.
Recirculation not activated.
3. Press
: the LED MAN comes on.
Recirculation is now activated.
You can switch between these three functions by repeatedly pressing
Keep the following in mind:
Make it a rule to have the Air quality
sensor activated at all times.
Recirculation is limited in cold climates to
avoid misting up.
If misting occurs, you should deactivate the
Air quality sensor.
If the windows mist up, you can also use
the windshield and side window defroster
functions. See page 49.
The filter should be changed at the intervals listed in the Warranty and Service Records Information booklet.
However, if the car is used in a severely contaminated
environment, it may be necessary to
change the filter more frequently.

A/C - ON/OFF
The air conditioning function is engaged by pressing ON and disengaged by pressing OFF. When you select Defroster 
, the air conditioning is automatically engaged if the fan is not set to position 0.
Heated front seats (option)
Please see page 38 for more information on this
function.
Heated rear window/sideview
mirrors
This function demists/de-ices the rear window
and sideview mirrors. The LED in the switch will
light up to indicate that the heating function is
engaged. See page 38 for additional information on this function.
CAUTION:
Never use ice scrapers made of metal as they can easily scratch the
mirror surface.
Recirculation
Recirculation can be used to shut out stale air, exhaust, etc. from the passenger 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. Recirculation (together with the air conditioning system) cools the passenger compartment more quickly in warm weather.
If you allow the air in the car to recirculate, there is a risk of icing and fogging, especially in winter. The timer function minimizes the risk of ice, misting and stale air.
Activate the timer function as follows:
Press for more that 3 seconds. the LED flashes for 5 seconds. the air recirculates in the car for 3-12 minutes depending on the outside temperature.
The timer function is activated each time you press .
To switch off the timer function :
Press again for more than 3 seconds. The LED lights for 5 seconds to confirm your selection.
Recirculation is always disconnected when you select Defroster
.
Blower
Blower speed can be increases or decreased by turning the knob. If the knob is set to 0, the air conditioning function is automatically disengaged.
Temperature
Turn the control to set the temperature for the driver's and passenger's sides of the car. For cooler air, the air conditioning function must be engaged.
Air distribution
Use the air distribution control positions (marked with dots) between the different symbols to fine-tune air distribution for the maximum comfort.
