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 that the multifilter/particle filter is
replaced regularly. Consult an authorised
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.
Ventilation fan function
When the engine is off (and if the ignition key
is in position
I or II ), the ventilation fan is
automatically switched off. This is to prevent
the battery from becoming discharged.
To activate the ventilation fan, turn the fan
control and set the desired speed.
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). Also, make sure the air
ducts in the parcel shelf are not blocked.
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 dehumidify the incoming air. This
provides better fuel economy compared to
conventional systems where the air condi-
tioning cools the air to just above freezing
point.
