climate control VOLVO S80 2008 User Guide

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.

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.

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

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.
132 04 Comfort and driving pleasure
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.

Audio system
Introduction
The audio system is available in two versions: High Performance and Premium Sound. The system version is shown in
the display when the audio system is switched on.
If the audio system is on when the ignition is switched off, it will come on automatically the next time the ignition is
put in mode I or higher. The audio system can be operated without a key in the ignition slot for 15 minutes at a time
by pressing the POWER button (the driver's door must be closed on vehicles with the optional keyless drive).
Some functions are controlled from the menu system in the center console. For more information on menus, see page
123.

Overview

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and many depart significantly from the norm due to variation in driving habits,
maintenance practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The traction
grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of cornering (turning)
traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of
cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a minimum level of performance that all
passenger vehicle tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.
WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and tire
failure.
