Air Conditioning; Actual Temperature; Sensor Location; Side Windows And Sunroof - Volvo XC70 Owner's Manual

General

Air conditioning

The car is equipped with Electronic Climate
Control (ECC) or Electronic Temperature
Control (ETC). The climate control system
cools or heats as well as dehumidifies the air
in the passenger compartment.
NOTE
The air conditioning can be switched off,
but to ensure the best possible climate
comfort in the passenger compartment and
to prevent the windows from misting, it
should always be on.

Actual temperature

The temperature you select corresponds to
the physical experience with reference to
factors such as air speed, humidity and solar
1
radiation etc. in and around the car.
The system includes a sun sensor
detects the side from which the sun is shin-
ing. This means that the temperature can dif-
fer between the right and left-hand air vents
despite the controls being set for the same
temperature on both sides.

Only applies to ECC

Sensor location

• The sun sensor is located on the top side
of the dashboard.
• The temperature sensor for the passenger
compartment is located below the climate
control panel.
• The outside temperature sensor is located
on the door mirror.
• The humidity sensor* is located in the
interior rearview mirror.
NOTE
Do not cover or block the sensors with
clothing or other objects.

Side windows and sunroof

To ensure that the air conditioning works
optimally, the side windows, and sunroof if
appropriate, should be closed.
Misting windows
1 Remove misting on the insides of the win-
which
dows by primarily using the defroster func-
tion.
To reduce the risk of misting, clean the win-
dows with a normal window cleaning agent.
Temporary shut-off of the air condi-
tioning
When the engine requires full power, e.g. for
full acceleration or driving uphill with a trailer,
04 Comfort and driving pleasure
the air conditioning could be temporarily
switched off. There may then be a temporary
1
increase in temperature.
Condensation
In warm weather, condensation from the air
conditioning may drip under the car. This is
normal.
Ice and snow
1
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 climate control system contains R134a
refrigerant. This refrigerant contains no chlo-
rine, which means that it is harmless to the
ozone layer. Have an authorised Volvo work-
shop carry out the filling/changing of refriger-
ant.
Total airing function
The function opens/closes all side windows
simultaneously and can be used for example
to quickly air the car during hot weather, see
page 39.
