2008 VOLVO S80 air conditioning

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 CFC-free 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,
dismantling information is available for all Volvo models. 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:
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 whenever possible.
See a trained and qualified Volvo service technician as soon as possible for inspection if the check engine (
malfunction indicator) light 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 vehicle, please use genuine Volvo car care products. All Volvo car care products are
formulated to be environmentally friendly.

Climate system
Introduction
Air conditioning
The vehicle is equipped with Electronic Climate Control (ECC). The climate control system cools, heats or
dehumidifies the air in the passenger compartment.
NOTE
The air conditioning can be switched off, but to ensure the best possible climate comfort in the passenger
compartment and to prevent the windows from misting, it should always be on.
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.
Sensor location
The sunlight sensor is located on the top side of the dashboard.
NOTE
The sunlight sensor monitors which side of the car that is most exposed to sunlight. This can mean that the
temperature may differ between the right and left-side air vents, even if the temperatures set for both sides of the
passenger compartment are the same.

The temperature sensor for the passenger compartment is located below the climate control panel.
The outside temperature sensor is located on the door mirror.
The humidity sensor (option) is located in the interior rearview mirror.
NOTE
Do not cover or block the sensors with clothing or other objects.
Side windows and moonroof
To ensure that the air conditioning works optimally, the side windows, and the optional moonroof should be closed.
Fog on the inside of the windows
The defroster function should be used to remove fog or mist from the inside of the windows. Keeping the windows
clean with a commercially available window washing spray will also help prevent fogging or misting.
Vents in the parcel shelf
NOTE
The air vents at the rear of the parcel shelf should never be obstructed.
Temporary shut-off of the air conditioning
The air conditioning is momentarily disengaged during full-throttle acceleration or when driving uphill with a trailer.
This may result in a temporary increase in cabin temperature.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Climate system maintenance
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
127 04 Comfort and driving pleasure
Climate system
will not deplete the ozone layer. The air conditioning system contains 1.8 lbs (800 g) of R134a. The systems 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 a trained and qualified Volvo service technician 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

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
If the blower is turned off completely, the air conditioning is disengaged, which may result in fogging on the
windows.
Heated front seats (option)
Press the button once for the highest heat level - three indicator lights come on.
Press the button twice for a lower heat level - two indicator lights come on.
Press the button three times for the lowest heat level - one indicator light comes on.
Press the button four times to switch off the heat - no indicator lights come on.
130 04 Comfort and driving pleasure
Climate system
Heated rear seats (option)
Heat control for the outboard seating positions takes place in the same way as for the front seat.
Air distribution
The figure consists of three buttons. When the buttons are pressed, an indicator light in front of the respective part of
the figure illuminates and shows which air distribution is selected, see page 133
.
Auto

The function automatically regulates cooling, heating, blower speed, recirculation, and air distribution to maintain the
chosen temperature. If you select one or more manual functions, the other functions continue to be controlled
automatically. The air quality sensor is engaged and all manual settings are switched off when AUTO is pressed. The
display shows AUTO CLIMATE.
Blower speed in automatic mode can be set under Climate settings
Automatic blower adjust . Choose between Low,
Normal or High.
NOTE
Selecting the lowest blower speed may increases the risk of fog forming on the windows.
For a description of the menu system, see page 123
.
Temperature control
The temperatures on the driver and passenger sides can be set independently. When the vehicle is started, the most
recent setting is resumed.
NOTE
Heating or cooling cannot be speeded up by selecting a higher/lower temperature than the actual temperature
required.
A/C - ON/OFF
The air conditioning is controlled automatically by the system when the ON light is on. This cools/heats and
dehumidifies the incoming air. When the OFF light is on, the air conditioning is always disengaged. Other functions
are still controlled automatically. When defroster is selected, the air conditioning system is set for maximum blower
speed and dehumidification.
131 04 Comfort and driving pleasure
Climate system
Defroster
This function defrosts/deices the windshield and front side windows. The indicator light in the defroster button lights
when the function is active.
Blower speed increases automatically and the air conditioning will switch on (if not already on and if the passenger
compartment blower is not turned off) to dehumidify the air in the passenger compartment. Air conditioning can be
switched off by pressing the AC button.
Recirculation will not function while defrost is engaged.
The climate system will return to its previous settings when the defroster function is switched off.

At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard maintenance intervals.
WARNING
Driving with the trunk open : Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed
so that capacity weight
189 05 During your trip
Driving recommendations
or maximum permissible axle loads are not exceeded.
Driving through water
The vehicle can be driven through water up to a depth of approximately 9 in. (25 cm), at a maximum speed of 6 mph
(10 km/h).
Take particular care when driving through flowing water.
Clean the electrical connections for trailer wiring after driving in mud or water.
When driving through water, maintain low speed and do not stop in the water.
WARNING
After driving through water, press lightly on the brake pedal to ensure that the brakes are functioning normally.
Water or mud can make the brake linings slippery, resulting in delayed braking effect.

1On vehicles with the optional keyless drive, the remote key must be in the passenger compartment.
CAUTION
Please check with state and local authorities before attempting this type of towing, as vehicles being towed are
subject to regulations regarding maximum towing speed, length and type of towing device, lighting, etc.
If the vehicle's battery is dead, do not attempt to start the vehicle by pushing or pulling it as this will damage the
three-way catalytic converter(s). The engine must be jump started using an auxiliary battery (see page 109
).
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the
flat bed. Consult the tow truck operator.
205 05 During your trip
Emergency towing
Towing vehicles with front wheel drive/All Wheel Drive
Volvo recommends the use of flat bed equipment.
If wheel lift equipment must be used, please use extreme caution to help avoid damage to the vehicle. In this case,
the vehicle should be towed with the rear wheels on the ground if at all possible .
If it is absolutely necessary to tow the vehicle with the front wheels on the ground, please refer to the towing
information on the page 204
.
CAUTION
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use sling -type equipment at the rear or apply lifting equipment inside the rear
wheels; serious damage to the rear axle may result.
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the
flat bed. Consult the tow truck operator.
