2007 VOLVO S40 air conditioning

ready access.
Do not export your Volvo to another country before investigating that country's applicable safety and emission
control requirements. In some cases it may be difficult or impossible to comply with these requirements. Modifications
to the emission control system(s) may render your Volvo not certifiable for legal operation in the U.S., Canada and
other countries.
All information, illustrations and specifications contained in this manual are based on the latest product information
available at the time of publication. Please note that some vehicles may be equipped differently, depending on special
legal requirements. Optional equipment described in this manual may not be available in all markets.
Volvo reserves the right to make model changes at any time, or to change specifications or design without notice
and without incurring obligation.
WARNING
If your vehicle is involved in an accident, unseen damage may affect its driveability and safety.
WARNING
CALIFORNIA proposition 65
Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the
state of California to cause cancer, and birth defects or other reproductive harm. In addition, certain fluids contained
in vehicles and certain products of component wear contain or emit chemicals known to the State of California to
cause cancer, and birth defects or other reproductive harm.

Volvo and the environment
Volvo is committed to the well being of its customers. As a natural part of this commitment, we care about the
environment in which we all live. Caring for the environment means an everyday involvement in reducing our
environmental impact. Volvo's environmental activities are based on a holistic view, which means we consider the
overall environmental 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 partly or completely phased out
several chemicals including CFCs, lead chromates, asbestos, and cadmium; and reduced the number of chemicals used
in our plants 50% since 1991.
Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda sond, now
called the heated oxygen sensor, in 1976. The current version of this highly efficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximately 95-99% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer to offer CFCfree retrofit kits for the air
conditioning system of all models as far back as the 1975 model 240. Advanced electronic engine controls and cleaner
fuels are bringing us closer to our goal. After Volvo vehicles and parts have fulfilled their use, recycling is the 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 controlled recycling, all
Volvo variants have printed dismantling manuals, indicating the weight and material of individual components. For
Volvo, all homogeneous plastic parts weighing more than 3.4 oz. (100 grams) are marked with international symbols
that indicate how the component is to be sorted for recycling. In addition to continuous environmental refinement of
conventional gasoline-powered internal combustion engines, Volvo is actively looking at advanced technology
alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment. To reduce
your vehicle's environmental impact, you can:

General information
Air conditioning - A/C
Your car is equipped with a climate control system that includes either manually adjustable air conditioning or optional
Electronic Climate Control (ECC).
The air conditioning system can be switched off, but for optimal air quality in the passenger compartment and to
prevent the windows from fogging, the air conditioning should be left on - even in cool weather.
NOTE
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.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Climate control maintenance
ProCarManuals.com

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 technician.
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 1.2 lbs (530 g) R134a (HFC 134a), and uses PAG
oil.
Passenger compartment 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.
NOTE
There are different types of cabin air filters. Ensure that the correct type is installed.
Display
The display above the climate control panel shows the climate settings that have been made.
Personal settings
There are two functions in the climate system that can be set to your preferences:
Blower speed to Auto mode (models with ECC only).
Timer controlled recirculation of the air in the passenger compartment. For information about how to make these
settings, see the Personal settings section on page 74
.

General information
Models equipped with ECC (option)
Sensors
The sunlight sensor on the upper side of the dashboard and the passenger compartment temperature sensor, located
behind the climate system control panel, should not be obstructed.
Side windows and optional moonroof
The electronic climate control system will function best if the windows and moonroof are closed. If you drive with the
windows or moonroof open, it may be preferable to manually adjust the temperature and blower control (the LED in
the AUTO switch should be off).
Acceleration
The air conditioning system is temporarily switched off during full throttle acceleration.

1. Blower
The blower speed can be increased or decreased by turning the knob. If the knob is turned counterclockwise and the
indicator light in the display goes out, the blower and the air conditioning are switched off. The display shows the
blower symbol and OFF.
2. Recirculation
This function can be used to shut out exhaust fumes, smoke, 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
very warm weather. 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.
Timer
The timer function minimizes the risk of misting, or stale air when the recirculation function is selected. See page 74
for information on setting the recirculation timer. Recirculation is always disengaged when you select Defroster (3).
3. Defroster
Directs airflow to the windshield and side windows and increases blower speed. When the defroster is activated:
Air flows to the windows at high blower speed.
The LED in the defroster button lights up when this function is activated. The air conditioning system is controlled
to provide maximum air dehumidification.
The air conditioning is automatically switched on (can be switched off by pressing button 5).
The air is not recirculated.
4. Airflow controls

windscreen is deactivated after approximately 12 minutes.
10. Temperature selector
The temperatures on the driver's and passenger's sides can be set separately using the knob (with the thermometer in
it). The temperature can be set for both sides of the car when the ignition is switched on (both LEDs will be on), which
means that a temperature setting will apply to both sides of the car.
