2004 VOLVO V70 air conditioning

Volvo and the environment
Volvo is committed to the well being of our 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 freons, lead chromates,
naphtanates, asbestos, mercury and cadmium; and reduced the amount of chemicals used in our plants 50% since 1991.
In use, Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda
sond, now called 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% 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 for all models as far back as the M/Y 1975 240. Advanced electronic engine controls, refined
purification systems and cleaner fuels are bringing us closer to our goal.
After Volvo cars 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 car, which makes the car among the most recycled industrial
products. In order to have efficient and well controlled recycling, many Volvo variants have printed dismantling
manuals, indicating the weight and material of individual components. For Volvo, all homogeneous plastic parts
weighing more than 1.7 oz. (50 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:
Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated tires
Follow the recommended maintenance schedule in your Warranty and Service Records Information booklet.
Drive at a constant speed
See an authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator) lamp
illuminates, or stays on after the vehicle has started
Properly dispose of any vehicle related waste such as used motor oil, used batteries, brake pads, etc.
When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to the
environment
PremAir®
On the surface of the radiator in the engine compartment, there is a special coating called PremAir®. PremAir® works
as a catalytic converter, converting most of the ozone passing through the radiator into oxygen, thereby reducing
harmful ground-level ozone.

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
ProCarManuals.com

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

up) will turn both the blower and the air conditioning off.
pg. 51 Electronic Climate Control (ECC) with Interior Air Quality system (option)
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.
ProCarManuals.com

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.

Heated rear window/sideview mirrors
ProCarManuals.com

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.
