NOTE
If a window is obstructed during auto-up, it
will automatically reverse direction and
return to its starting position. If a window is
repeatedly obstructed during auto-up oper-
ation, an overload protection circuit breaker
will temporarily halt window function. The
window will return to normal function after a
brief cool-down period.
WARNING
Always remove the ignition key when the
vehicle is unattended.
Make sure that the windows are completely
unobstructed before they are operated.
Never leave children unattended in the vehi-
cle.
NOTE
To reduce buffeting wind noise if the rear
windows are opened, also open the front
windows slightly.

Rearview mirror
G026660
To reduce glare from the headlights of follow-
ing vehicles, use the control to switch between
the normal and night-driving positions.
Normal position
Night position, reduces glare from follow-
ing headlights
Autodim function*The autodim function reacts to headlights from
following traffic and automatically reduces
glare.
NOTE
This function is automatically switched off
when the gear selector is placed in the
Reverse position.
Rearview mirror with compass*
G026965
The upper left-hand corner of the rearview mir-
ror has an integrated display that shows the
compass direction toward which the car is
pointing. Eight different directions can be dis-
played:
N, NE, E, SE, S, SW, W and NW. The
display shows your car's orientation with
respect to true north.
If the compass is activated, it will be displayed
automatically when the ignition is in postilion IIor when the engine is running. The compass
can be switched off or on by pressing the inset
button on the rear side of the mirror (see the
inset illustration). This can be done with
straightened paperclip or similar object. The
button is recessed approximately 1 in. (2.5 cm)
in the mirror.
G026409
Magnetic zonesThe earth is divided into 15 magnetic zones.
The compass is initially set for the zone to
which the car was delivered, and should
always be adjusted if the car is driven to a new
magnetic zone. To do so:
1.
Switch the ignition to position II.

83 Power moonroof
G007503
To operate the moonroof, turn the ignition key
to position I or II, or start the engine. The moon-
roof can be operated in two ways:
Tilt position
Sliding moonroof
G027010
Tilt positionOpen: With the moonroof closed, push up the
rear edge of the switch (position 5 in the illus-
tration in the center column).
Close: Pull down and hold the rear edge of the
switch (position 6 in the illustration in the center
column) until the moonroof has closed com-
pletely.
Sliding moonroofManual open: Pull the switch rearward to posi-
tion 3 and hold it until the moonroof has
opened to the position of your choice.Auto open: Pull the switch as far back as pos-
sible (position 4) and release it to automatically
slide open the moonroof to the "comfort"
1
position. Pull the switch rearward again to
open the moonroof completely.
Manual close: Push the switch to position 2
and hold it until the moonroof has closed com-
pletely or to the position of your choice.
Auto close: Push the switch forward as far as
possible (position 1) and release it to automat-
ically close the moonroof.
CAUTION
•Remove ice and snow before opening
the moonroof.
•Do not operate the moonroof if it is fro-
zen closed.
•Never place heavy objects on the
moonroof.
1A position where the moonroof is not quite fully open, which helps alleviate "rumbling" wind noise.

03 Climate
Climate control system – general information

90* Option/accessory, for more information, see Introduction.
Condensation on the inside of the
windows
Keeping the insides of the windows clean will
help reduce the amount of condensation that
forms on the windows. Use a commercial win-
dow cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of
the windshield free of snow.
Cabin air filter
Replace 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.
Sensors
The sunlight sensor on the dashboard and pas-
senger compartment temperature sensor in
the ECC control panel should not be covered
in any way as this could cause incorrect infor-
mation to be sent to the ECC system.
Parking the vehicle in warm weather
If your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof* for several minutes before driving
will help release the warm air from the passen-
ger compartment. When the engine is running,
close the windows and moonroof and use the
recirculation function for several minutes to
enable the air conditioning to cool the com-
partment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the win-
dows and optional moonroof are closed. If you
drive with the moonroof open, we recommend
that you manually adjust the temperature and
blower control (the LED in the AUTO switch
should be off).
Acceleration
The air conditioning is momentarily disen-
gaged during full-throttle acceleration.
Climate control maintenance
Special 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.
Refrigerant
Volvo cares about the environment. The air
conditioning system in your vehicle contains a
CFC-free refrigerant – R134a (HFC134a). This
substance will not deplete the ozone layer. The
approximate amount of R134a contained in the
system is a follows:
6-cylinder engine
Single A/C system: 1.4 lbs (700 g)
Dual
1 A/C system: 2.2 lbs (1000 g)
8-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual
1 A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.

91 Climate system blower
The climate system blower will be automati-
cally switched off when the engine is not run-
ning (even if the ignition key is in position I or
II) to avoid unnecessary battery drain. To acti-
vate the blower, turn the control to the desired
setting.
The climate system blower may start automat-
ically during a period of up to approximately
50 minutes after the ignition has been turned
off to remove condensation in the A/C evapo-
rator. It will run for 15 minutes and switch off
automatically.
Passenger compartment blower
Approximately 50 minutes after the ignition is
turned off, the blower may come on automati-
cally, and run for seven minutes, to remove
condensation in the A/C evaporator.
Blower function to reduce battery drain
The climate system's blower functions nor-
mally while the engine is running.
However, when the engine is switched off
(even if the ignition is switched to positions I or
II), the blower control will be automatically
switched off to avoid unnecessary battery
drain.The following points pertain if the ignition is on
but the engine in not running:
•To restart the blower, turn the control knob
to the setting of your choice.
•After approximately 2 minutes, the blower
speed will be reduced to avoid battery
drain.
You can reset the blower speed at any time.
Please be aware that the system has been
designed to reduce the blower's speed again
after 2 minutes, until the engine is started.
If the battery becomes drained:
•LOW BATTERY, FAN IS REDUCED will
be displayed in the text window in the
instrument panel.
•The yellow warning light in the instrument
panel (see page 54) will also light up.

into position after adjusting.
Folding the backrests in the front seat
G014805
The front passenger seat backrest can be
folded to a horizontal position to make room for
a long load. Fold the backrest as follows:1. Move the seat as far back as possible.
2. Adjust the backrest to the upright position.
3. Lift the catches on the rear of the backrest.
4. Without releasing the catches, push the
backrest forward.
5. Move the seat as far forward as possible
so that the head restraint slides under the
glove compartment.
WARNING
Cover sharp edges on the load to help pre-
vent injury to occupants. Secure the load to
help prevent shifting during sudden stops.

ferent seating position and locked the
vehicle with a different remote key.
•This feature will work in the same way
with all of the remote key transmitters
(up to 3 ) that you use with your vehicle.
•This feature will not function if you lock
