General information on climate control

03

Air conditioning

The climate control system cools or heats,

and dehumidifies the air entering the passen-

ger compartment. The car is equipped with

electronic climate control (

ECC).

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 con-

trol 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 air conditioning 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 au-

thorised 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 au-

tomatically 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.

ECC (option)

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.

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

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 con-

trolled 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 condi-

tioning cools the air to just above freezing

point.

NOTE

The air conditioning can be switched off, but

to ensure the best possible air in the passen-

ger compartment and prevent the windows

from misting, it should always be on.

NOTE

Do not cover or block the sensors with

clothing or other objects.
