impact of a product throughout its complete life cycle. In this context,\
design, production, product use, and
recycling are all important considerations. In production, Volvo has par\
tly or completely phased out several
chemicals including freons, lead chromates, naphtanates, asbestos, mercu\
ry and cadmium; and reduced the amount
of chemicals used in our plants 50% since 1991.
Volvo was the first in the world to introduce into production a three-wa\
y catalytic converter with a Lambda sond,
now called oxygen sensor, in 1976. The current version of this highly ef\
ficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximatel\
y 95% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer\
to offer CFC-free retrofit kits for the
air conditioning system of all models as far back as the 1975 model 240.\
Advanced electronic engine controls,
refined purification systems and cleaner fuels are bringing us closer to\
our goal.
After Volvo vehicles and parts have fulfilled their use, recycling is th\
e next critical step in completing the life
cycle. The metal content is about 75% of the total weight of a vehicle, \
which makes the vehicle among the most
recycled industrial products. In order to have efficient and well contro\
lled recycling, many Volvo variants have
printed dismantling manuals, indicating the weight and material of indiv\
idual components. For Volvo, all
homogeneous plastic parts weighing more than 1.7 oz. (50 grams) are ma\
rked with international symbols that
indicate how the component is to be sorted for recycling.
In addition to continuous environmental refinement of conventional gasol\
ine-powered internal combustion
engines, Volvo is actively looking at advanced technology alternative-fu\
el vehicles.
When you drive a Volvo, you become our partner in the work to lessen the\
vehicle's impact on the environment.
To reduce your vehicle's environmental impact, you can:
l Maintain proper air pressure in your tires. Tests have shown decreased f\
uel economy with improperly inflated
tires.
l Follow the recommended maintenance schedule in your Warranty and Service\
Records Information booklet.
l Drive at a constant speed.
l See an authorized Volvo retailer as soon as possible for inspection if t\
he check engine (malfunction indicator)
lamp illuminates, or stays on after the vehicle has started.
l Properly dispose of any vehicle-related waste such as used motor oil, us\
ed batteries, brake pads, etc.
l When cleaning your vehicle, use Volvo's own vehicle care products, all o\
f which have systematically been
adapted to the environment.
PremAir® (certain models only)
The surface of the radiator in the engine compartment
1 is treated with a special coating called PremAir2. This
coating works as a catalytic converter, converting most of the ground le\
vel ozone passing through the

Climate control systems - 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 the recommended intervals\
. Please refer to your Warranty and Service
Records Information booklet, or consult your Volvo retailer for these in\
tervals. The filter should be replaced more
often when driving under dirty and dusty conditions. The filter cannot b\
e 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 informati\
on 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 (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 se\
veral 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).

The air conditioning is momentarily disengaged during full-throttle acce\
leration.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repai\
rs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.\
Refrigerant
Volvo cares about the environment. The air conditioning system in your v\
ehicle contains a CFC-free refrigerant -
R134a (HFC134a). This substance will not deplete the ozone layer. The \
system contains 1.5 lbs (700 g) R134a and
uses PAG oil.
Climate system blower
The climate system blower will be automatically switched off when the en\
gine is not running (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.
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.

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 multi-filter and air quality sensor. T\
he filter separates gases and particles,
thereby reducing the amounts of odors and contaminants entering the vehi\
cle. The air quality sensor detects
increased levels of contaminants in the outside air. When the air qualit\
y sensor detects contaminated outside air, the
air intake closes and the air inside the passenger compartment is recirc\
ulated, i.e. no outside air 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 77.
l The filter should be changed at the intervals recommended in the service\
schedule. However, if the vehicle is
used in a severely contaminated environment, it may be necessary to chan\
ge the filter more frequently.
