2006 VOLVO S40 climate control

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) 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.
Introduction
When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to the
environment.
PremAir®
The surface of the radiator in the engine compartment is treated with a special coating called Premair
1. This coating
works as a catalytic converter, converting most of the ground level ozone passing through the radiator into oxygen,
thereby reducing harmful ground-level ozone.

pg. 62 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
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 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.
Display
The display above the climate control panel shows the climate settings that have been made.
ProCarManuals.com

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 57
.
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.

Manual climate system functions
1. Blower speed
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 57
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.
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 is not recirculated.
pg. 65 Manual climate control
4. Airflow controls
Press one of the three buttons in the illustration to activate the selected airflow. A symbol in the display
above the climate control panel and a lit LED in the selected button indicate that the manual function has been
selected. With manually selected airflow both warm and cool air can be selected. The desired temperature is selected
using control 9.
5. A/C - On or Off
The air conditioning system is engaged when the ON LED is lit. The system is disengaged when the OFF
lights up. If Defroster (3) is activated the air conditioning is always engaged.
6/7. Heated front seats (option)
Maximum heating: Press the button once - both LEDs light up.
Reduced heating: Press the button a second time - one LED lights up.
Seat heating off: Press the button a third time - no LEDs are lit.
8. Heated rear window and door mirrors
Use this function to defrost the rear window and door mirrors.
9. Temperature selector
The knob with the thermometer symbol is used to select cooling or heating for both the driver's and passenger's sides
of the car.

ECC functions
1. Auto -On/Off
The AUTO function automatically regulates climate control to maintain the desired temperature. The automatic
function controls heating, air conditioning, blower speed, recirculation, and air distribution.
If you select one or more manual functions, the remaining functions continue to be controlled automatically. All
manual settings are switched off when AUTO is switched on. AUTO CLIMATE is shown in the display.
2. Blower speed
The blower speed can be increased or decreased by turning the knob. The blower speed is regulated automatically if
AUTO is selected. The previously set blower speed is disconnected.
NOTE: If the knob is turned counterclockwise and the blower indication in the display goes out, the blower and the air
conditioning are switched off. The display shows the blower symbol and OFF.
