Climate control system-general information
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 intervals shown in your W\
arranty and Service Records Information booklet.
The filter should be replaced more often when driving under dirty and du\
sty 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 temperatu\
re sensor in the ECC control panel should not
be covered in any way as this could cause incorrect information to be se\
nt 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 (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 a\
re 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 acce\
leration.
Climate control 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 v\
ehicle 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 ma\
y come on automatically, 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 normally while the engine is runni\
ng.
However, when the engine is switched off (even if the ignition is switc\
hed to positions I or II), the blower control will be
automatically switched off to avoid unnecessary battery drain. The follo\
wing points pertain if the ignition key is on but the
engine is not running:
l To restart the blower, turn the control knob to the setting of your choi\
ce.
l 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 sys\
tem has been designed to reduce the blower's speed
again after 2 minutes, until the engine is started. If the battery becom\
es drained:
l LOW BATTERY, FAN IS REDUCED will be displayed in the text window in the \
instrument panel.
l The yellow warning light in the instrument panel (see page 25) will also light up.

AUTO
This function automatically regulates the Electronic Climate Control sys\
tem so that the selected temperatures are
maintained. The blower, heating, air distribution (air flow) and air c\
onditioning are controlled.
If you prefer to manually set any of these functions, the remaining func\
tions will still be controlled automatically. Pressing
the AUTO button overrides any settings that were previously made manuall\
y.
Rear window and sideview mirror defrosters
This function defrosts/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 35 for additional information on this function.
Never use ice scrapers made of metal as the can easily scratch the mirro\
r surface.
Temperature
These controls are used to individually set the temperature for both sid\
es of the passenger compartment. Please note that the
compartment will not be heated or cooled faster by setting the temperatu\
re higher or lower than necessary.

Defroster
This function defrosts/de-ices the windshield and front side windows. Th\
e LED in the switch will light up to indicate that
the defrost function is engaged. Blower speed increases automatically an\
d the air in the passenger compartment is
dehumidified. Recirculation will not function while defrost is engaged. \
Blower control*
Turn the control clockwise to increase or counterclockwise to decrease t\
he blower speed. Pressing the AUTO switch will
automatically regulate blower speed and override manual adjustment.
NOTE: Turning the blower control counterclockwise until an orange LED comes on\
will turn both the blower and the air
conditioning off.

A/C - ON/OFF
Press the switch to turn the air conditioning on or off. The "ON" or "OF\
F" LED will light up to indicate if the system is
switched on or off. Other functions will still be regulated automaticall\
y (if the AUTO switch is on).
l The air conditioning functions only at temperatures above 32° F (0°\
C).
l While the Defroster function is selected, the air conditioning is tempor\
arily 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.
Recirculation
Press this switch to engage the recirculation function (air in the pass\
enger compartment recirculates - no fresh air enters the
compartment). The LED in the switch will light up to indicate that the \
function is engaged.
l Use this function if the outside air is contaminated with exhaust gases,\
smoke, etc or to heat/cool the vehicle quickly.
l 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.
l Selecting Defroster automatically switches recirculation off.
l Timer mode activation: (Vehicles equipped with the Interior Air Quality System have no timer m\
ode) Press and hold
the recirculation button for at least 3 seconds to activate a recirculat\
ion 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 the recirculation button is
pressed, the climate control system will recirculate the air in the pass\
enger compartment for 5-12 minutes, depending on the
outside air temperature, and then revert back to fresh air.
l Timer mode deactivation: Press and hold the recirculation button for 3 s\
econds. The amber LED in the recirculation
button will illuminate steadily for 5 seconds to show a return to "norma\
l" mode.
pg. 51 Climate control

l In normal mode, when the recirculation button is pressed, the climate co\
ntrol system will recirculate the air in the
passenger compartment until the recirculation button is pressed again.
l Timer mode memory: If the vehicle is turned off while timer mode is acti\
ve, timer mode will still be active when the
vehicle is restarted.
Interior Air Quality sensor (option)
Some vehicles are equipped with a multifilter and Air Quality sensor. Th\
e 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 con\
taminated outside air, the air intake closes and the
air inside the passenger compartment is recirculated, i.e. no outside ai\
r enters the vehicle. The filter also cleans recirculated
passenger compartment air. When the ECC system is in the AUTO mode, the \
green LED will be on
.

Operation
Press
to operate the Air Quality sensor (normal setting).
Or:
Select one of the following three functions by pressing
1, 2 or 3 times.
1. The AUT LED lights. The Air Quality sensor is now activated.
2. No LED lights. Recirculation is not activated unless needed to cool t\
he passenger compartment in a warm climate.
3. The MAN LED lights. Recirculation is now activated.
Keep in mind the following:
l Make it a rule to have the Air Quality sensor activated at all times.
l Recirculation is limited in cold climates to avoid fogging.
l If window fogging occurs, you should deactivate the Air Quality sensor. \
l If fogging occurs, use the defroster functions for the windshield, side \
windows and rear window. See page 49.
l The filter should be changed at the intervals recommended in the mainten\
ance schedule. However, if the vehicle is used
in a severely contaminated environment, it may be necessary to change th\
e filter more frequently.
