03 ClimateGeneral information

Air conditioning – A/CYour car is equipped with a climate control
system that includes either manually adjusta-
ble air conditioning or optional Electronic Cli-
mate Control (ECC).
The air conditioning system can be switched
off, but for optimal air quality in the passenger
compartment and to prevent the windows from
fogging, the air conditioning should be left on
– even in cool weather.
NOTE
In warm weather, a small amount of water
may accumulate under the car when it has
been parked. This water is condensation
from the A/C system and is normal.Ice and snowAlways keep the air intake grille at the base of
the windshield free of snow.
Fog on the inside of the windowsThe defroster function should be used to
remove fog or mist from the inside of the win-
dows. Keeping the windows clean with a com-
mercially available window washing spray will
also help prevent fogging or mistingClimate control maintenanceSpecial tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.RefrigerantVolvo cares about the environment. The air
conditioning system in your car contains a
CFC-free refrigerant – R134a. This substance
will not deplete the ozone layer. The system
contains 1.2 lbs (530 g) R134a (HFC 134a), and
uses PAG oil.
Passenger compartment filterReplace the cabin air filter with a new one at
the recommended intervals. Please refer to
your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
NOTE
There are different types of cabin air filters.
Ensure that the correct type is installed.DisplayThe display above the climate control panel
shows the climate settings that have been
made.Personal settingsThere are two functions in the climate system
that can be set to your preferences:•
Blower speed to Auto mode (models with
ECC only).
•
Timer controlled recirculation of the air in
the passenger compartment.

General information
0393
For information about how to make these set-
tings, see the Personal settings section on
page 83.Models equipped with ECC (option)Sensors•
The sunlight sensor is on the upper side of
the dashboard
•
The passenger compartment temperature
sensor is located behind the climate sys-
tem control panel.
•
The ambient temperature sensor is in the
driver's side door mirror.
•
The humidity sensor is in the rearview mir-
ror.
These sensors should never be obstructed.NOTE
The sunlight sensor monitors the side of the
vehicle from which the sun shines into the
passenger compartment. This means that
the temperature may differ slightly between
the left and right air vents, even if the climate
system temperature is set to be the same
for both sides of the passenger compart-
ment.Side windows and optional moonroofThe electronic climate control system will func-
tion best if the windows and moonroof areclosed. If you drive with the windows or moon-
roof open, it may be preferable to manually
adjust the temperature and blower control (the
LED in the AUTO switch should be off).
AccelerationThe air conditioning system is temporarily
switched off during full throttle acceleration.

Manual climate system functions1. Blower
The blower speed can be
increased or decreased by
turning the knob. If the knob is
turned counterclockwise and
the indicator light in the dis-
play goes out, the blower and
the air conditioning are
switched off. The display shows the blower
symbol and
OFF.
2. Recirculation
This function can be used to
shut out exhaust fumes,
smoke, etc from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e. no air
from outside the car is taken
into the car when this function is activated.
Recirculation (together with the air condition-
ing system) cools the passenger compartment
more quickly in very warm weather. If the air in
the car recirculates for too long, there is a risk
of condensation forming on the insides of the
windows, especially in winter.

TimerThe timer function minimizes the risk of mist-
ing, or stale air when the recirculation function
is selected, see page 83 for information on set-
ting the recirculation timer. Recirculation is
always disengaged when you select Defroster
(3).3. Defroster
Directs airflow to the wind-
shield and side windows and
increases blower speed.
When the defroster is activated:•
Air flows to the windows at high blower
speed.
•
The LED in the defroster button lights up
when this function is activated. The air con-
ditioning system is controlled to provide
maximum air dehumidification.
•
The air conditioning is automatically
switched on (can be switched off by press-
ing button 5).
4. Airflow controls
Press one of the three buttons
in the illustration to activate
the selected airflow. A symbol
in the display above the cli-
mate control panel and a lit
LED in the selected button
indicate that the manual func-
tion has been selected. With manually selected
airflow both warm and cool air can be selected.
The desired temperature is selected using con-
trol 9.
5. A/C – On or Off
ON: The air conditioning sys-
tem is engaged when the ON
light is lit.
OFF: The system is disen-
gaged when the OFF lights
up.
If Defroster (3) is activated the air conditioning
is always engaged.6/7. Heated front seats (option)
Maximum heating: Press the
button once – both LEDs light
up.
Reduced heating: Press the button a second
time – one LED lights up.
Seat heating off: Press the button a third time
– no LEDs are lit.8. Heated rear window and door mirrors
Press to defrost the rear win-
dow and door mirrors.
The rear window and door
mirrors are defrosted simulta-
neously if the switch is
pressed once. The defrost
function is active if the LED in the switch is illu-
minated.
•
The function can be switched off manually
by pressing the button,
•
The defrost function switches off automat-
ically after 12–20 minutes, depending on
the outside temperature.NOTE
On certain markets, the defrost function
may remain on longer than 20 minutes in
cold weather to help keep the rear window
free from ice or condensation.

10. Temperature selector
The temperatures on the driv-
er's and passenger's sides
can be set separately using
the knob (with the thermome-
ter in it). The temperature can
be set for both sides of the car
when the ignition is switched
on (both LEDs will be on), which means that a
temperature setting will apply to both sides of
the car.
To set the temperature on one side of the car:
1. Press the knob once. The LED for one side
of the car will light up. Turn the knob to
adjust the temperature.
2. Press the knob a second time to set the
temperature on the opposite side of the
car.
3. Press the knob a third time to set the tem-
perature on both sides of the car at the
same time.
NOTE
Selecting a temperature that is higher or
lower than necessary will not heat or cool
the passenger compartment faster.
