If the PASSENGER AIRBAG OFF indicator
lamp remains on even after this, the person
should be advised to ride in the rear seat.
This condition reflects limitations of the OWS
classification capability. It does not indicate
OWS malfunction.ModificationsIf you are considering modifying your vehicle in
any way to accommodate a disability, for
example by altering or adapting the driver's or
front passenger's seat(s) and/or airbag sys-
tems, please contact Volvo at:

WARNING
•
No objects that add to the total weight
on the seat should be placed on the
front passenger's seat. If a child is
seated in the front passenger's seat
with any additional weight, this extra
weight could cause the OWS system to
enable the airbag, which might cause it
to deploy in the event of a collision,
thereby injuring the child.
•
The seat belt should never be wrapped
around an object on the front passeng-
er's seat. This could interfere with the
OWS system's function.
•
The front passenger's seat belt should
never be used in a way that exerts more
pressure on the passenger than normal.
This could increase the pressure exer-
ted on the weight sensor by a child, and
could result in the airbag being enabled,
which might cause it to deploy in the
event of a collision, thereby injuring the
child.
WARNING
Keep the following points in mind with
respect to the OWS system. Failure to follow
these instructions could adversely affect the
system's function and result in serious injury
to the occupant of the front passenger's
seat:•
The full weight of the front seat passen-
ger should always be on the seat cush-
ion. The passenger should never lift
him/herself off the seat cushion using
the armrest in the door or the center
console, by pressing the feet on the
floor, by sitting on the edge of the seat
cushion, or by pressing against the
backrest in a way that reduces pressure
on the seat cushion. This could cause
OWS to disable the front passenger's
side airbag.
•
Do not place any type of object on the
front passenger's seat in such a way
that jamming, pressing, or squeezing
occurs between the object and the front
seat, other than as a direct result of the
correct use of the Automatic Locking
Retractor/Emergency Locking Retrac-
tor (ALR/ELR) seat belt (see page 34).
•
No objects should be placed under the
front passenger's seat. This could inter-
fere with the OWS system's function.

WARNING
A child seat should never be used in the
front passenger seat of any vehicle with a
front passenger airbag – not even if the
"Passenger airbag off" symbol near the
rear-view mirror is illuminated (on vehicles
equipped with Occupant Weight Sensor). If
the severity of an accident were to cause the
airbag to inflate, this could lead to serious
injury or death to a child seated in this posi-
tion.3. Fasten the seat belt by inserting the latch
plate into the buckle (lock) until a distinct
click is audible.

CAUTION
•
Use ample washer fluid when washing
the windshield to avoid scratching the
glass. The windshield should be thor-
oughly wet when the wipers are in oper-
ation.
•
Before using the wipers, ice and snow
should be removed from the wind-
shield/rear window. Be sure the wiper
blades are not frozen in place.

Condensation on the inside of the
windowsKeeping 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 snowAlways keep the air intake grille at the base of
the windshield free of snow.Cabin air 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.
SensorsThe 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 weatherIf your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof (option) for several minutes before
driving will help release the warm air from the
passenger 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 compartment as quickly as possible.Windows and optional moonroofThe 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).
AccelerationThe air conditioning is momentarily disen-
gaged during full-throttle acceleration.Climate 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 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)
Dual1 A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.

Interior air quality sensor (option)Some vehicles are equipped with a multifilter
and air quality sensor. The filter separates
gases and particles, thereby reducing the
amounts of odors and contaminants entering
the vehicle. The air quality sensor detects
increased levels of contaminants in the outside
air. When the air quality sensor detects conta-

minated outside air, the air intake closes and
the air inside the passenger compartment is
recirculated, i.e. no outside air enters the vehi-
cle. The filter also cleans recirculated passen-
ger compartment air.
When the ECC system is in the AUTO mode,
the green LED will be on. RecirculationPress this switch to engage the recirculation
function (air in the passenger compartment
recirculates – no fresh air enters the compart-
ment). The LED in the switch will light up to
indicate that the function is engaged.•
Use this function if the outside air is con-
taminated with exhaust gases, smoke, etc
or to heat/cool the vehicle quickly.
