light VOLVO S40 2008 Service Manual

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.
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 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.
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.
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 77
.

Sensors
The sunlight sensor is on the upper side of the dashboard
The passenger compartment temperature sensor is located behind the climate system control panel.
The ambient temperature sensor is in the driver's side door mirror.
The humidity sensor is in the rearview mirror.
These sensors should never be obstructed.

NOTE
The sunlight sensor monitors the side of the vehicle from which the sun shines into the passenger compartment. This
means that the temperature may differ slightly between the left and right air vents, even if the climate system
temperature is set to be the same for both sides of the passenger compartment.
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.

1. Blower
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

The driver's and passenger's seats can be adjusted in a number of ways to provide a comfortable driving and sitting
position.
1. Forward-rearward: Pull the lever up and slide the seat to the position of your choice.
