2008 VOLVO S80 air filter

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

There are different types of cabin air filters. Ensure that the correct type is installed.
Interior Air Quality System (IAQS)
A multifilter helps reduce gases and particles in the incoming air, thereby reducing the levels 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 contaminated outside air, the air intake closes and the air inside the passenger
compartment is recirculated, i.e. no outside air enters the vehicle. The filter also cleans recirculated passenger
compartment air.
NOTE
Contact your Volvo retailer for IAQS air filter replacement intervals.
Menu settings
The default settings for three of the climate system's functions can be changed in the menu system, see page 123
:
Blower speed in automatic mode, see page 130.
Recirculation timer for passenger compartment air, see page 130.
Automatic rear window defrosting, see page 100.
The functions can also be returned to factory settings in the menu system.

Air distribution
The incoming air is distributed from 20 different vents in the passenger compartment.
Air distribution is fully automatic in AUTO mode.
If desired, air distribution can be controlled manually, see page 133
.
Air vents in the dashboard

Recirculation/air quality system
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. The indicator light in the button will illuminate when recirculation is selected.
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 fogging, or stale air when the recirculation function is selected by
automatically switching off the function after a certain length of time, depending on the ambient temperature.
Activate/deactivate the function under Climate control settings
Recirculation timer .
For a description of the menu system, see page 123
.
NOTE
When Defroster is selected, recirculation is always deactivated.
Interior Air Quality System -IAQS (option)
This system consists of a multifilter and an air quality sensor. The filter helps remove gases and particles from the
incoming air, 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 contaminated outside
air, the air intake closes and the air inside the passenger compartment is recirculated, i.e., no outside air enters the
vehicle. The filter also cleans recirculated passenger compartment air. When the AUTO button is depressed the air
quality sensor is always engaged.
Activating the air quality sensor
Switch between the three functions by pressing the button repeatedly.
The left orange light comes on - the air quality sensor is disengaged.
The center green light comes on - recirculation not engaged, providing it is not required for cooling in hot weather.
The right orange light comes on - recirculation is engaged.

Climate system
NOTE
The air quality sensor should always be engaged in order to obtain the best air in the passenger compartment.
Recirculation is limited in cold weather to avoid fogging.
If the insides of the windows start fogging, disengage the air quality sensor. Use the defroster function to increase
airflow to the front, side, and rear windows.

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

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.
