Climate control

General information on climate control

Misting windows
Reduce the problem of windows misting up
on the inside by cleaning the windows. Use a
regular window cleaner.
Particle filter
Make sure the particle filter is replaced
regularly. Consult your Volvo workshop.
Ice and snow
Remove ice and snow from the climate
control air intake (the grille between the
bonnet and the windscreen).
Fault tracing
An authorised Volvo workshop has the instru-
ments and tools required for any fault tracing
or repair of your climate control system.
Entrust checks and repairs only to trained
personnel.
Refrigerant
The air conditioning system contains R134a
refrigerant. This refrigerant contains no
chlorine, which means that it is harmless to
the ozone layer. The system must only be
charged with R134a refrigerant. Have an
authorised Volvo workshop carry out this
work.
SO
Fan function to reduce risk of
battery discharge
When the engine is switched off (even if the
ignition key is in position I or II), the fan will
be switched off automatically. To activate the
fan, turn the knob and set the desired speed.
After two minutes, the fan will reduce to a
lower speed. This is one way to avoid
discharging the battery when the engine is
switched off.
Cars with ECC
Actual temperature
The temperature you select corresponds to
the physical experience with reference to air
speed, humidity, exposure to sun, etc. which
affect the interior and exterior of the car.
Sensors
The sun sensor is on the upper portion of the
dashboard. Remember not to cover it. Do not
cover the passenger compartment temper-
ature sensor on the climate control panel.
Side windows and sunroof
To ensure that the air conditioning works
satisfactorily, close all side windows and the
sunroof (if fitted).
Acceleration
The air conditioning system switches off
temporarily at full acceleration. You may feel
a temporary rise in temperature.
Condensation
In warm weather, condensation from the air
conditioning system may drip under the car.
This is normal.
Fuel economy
With ECC, the air conditioning system is
controlled automatically and is used just
enough to cool the passenger compartment
and to adequately dehumidify the incoming
air. This provides better fuel economy
compared to conventional systems where the
air conditioning cools the air to just above
freezing point.
