03 Climate control

General information on climate control

Air conditioning
The climate control system cools or heats as
well as dehumidifies the air in the passenger
compartment. The car is equipped with elec-
tronic climate control (ECC).

NOTE
The air conditioning can be switched off, but
to ensure the best possible air in the pas-
senger compartment and prevent the win-
dows from misting, it should always be on.
Misting windows
Reduce the problem of windows misting up on
the inside by cleaning the windows. Use a reg-
ular 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
system air intake (the grille between the bonnet
and the windscreen).
Fault tracing and repair
Entrust fault tracing and repair of the climate
control system to an authorised Volvo work-
shop only.
Refrigerant
The climate control system contains R134a
refrigerant. This refrigerant contains no chlo-
rine, 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 auto-
matically switched off. This is to prevent the
battery from becoming discharged.
To activate the ventilation fan, turn the fan con-
trol and set the desired speed.
ECC (electronic climate control)
Actual temperature
The temperature you select corresponds to the
physical experience with reference to factors
such as air speed, humidity and solar radiation
in and around the car.
Sensor location
•
The sun sensor is on the top side of the
dashboard.
•
The temperature sensor for the passenger
compartment is behind the climate control
panel.
NOTE
Do not cover or block the sensors with
clothing or other objects.
Side windows and sunroof
To ensure that the air conditioning works sat-
isfactorily, the side windows, and sunroof if
appropriate, should be closed.
Acceleration
The air conditioning system switches off tem-
porarily at full throttle. You may briefly feel a
temporary rise in temperature.
