pg. 10 Occupant Weight Sensor (OWS)
WARNING!
If a fault in the system is detected and indicated as explained on the previous page, be aware that the passenger's
side front airbag will not deploy in the event of a collision. In this case, the safety systems and Occupant Weight
Sensor should be inspected by an authorized Volvo retailer as soon as possible.
Modifications
If 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 systems, please contact Volvo at:

1-800-663-8255 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
ProCarManuals.com

never be wrapped around an object on the front passenger'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 exerted 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!
Never try to open, remove, or repair any components in the OWS system. This could result in system malfunction.
Maintenance or repairs should only be carried out by an authorized Volvo service technician. 'The front passenger's
seat should not be modified in any way. This could reduce pressure on the seat cushion, which might interfere with
the OWS system's function.
pg. 11 Occupant Weight Sensor (OWS)
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 passenger should always be on the seat cushion. 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 ALR/ELR seat belt
(see page 21
).
No objects should be placed under the front passenger's seat. This could interfere with the OWS system's function.

car has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or tensioner, a front
airbag, side impact airbag, and/or an inflatable curtain. Have the system(s) inspected by a trained and qualified Volvo
service technician as soon as possible.

Press the switch to turn the air conditioning on or off. The "ON" or "OFF" LED will light up to indicate if the system
is switched on or off. Other functions will still be regulated automatically (if the AUTO switch is on).
The air conditioning functions only at temperatures above 32° F (0° C).
While the Defroster function is selected, the air conditioning is temporarily activated to dehumidify the air, even if
you have manually switched the air conditioning off. This will only function if the blower is not switched off.
Blower control
Turn the control clockwise to increase or counterclockwise to decrease the blower speed. Pressing the AUTO switch
will automatically regulate blower speed and override manual adjustment.
NOTE: Turning the blower control counterclockwise as far as possible (an orange LED next to the control will light
up) will turn both the blower and the air conditioning off.
pg. 50 Climate control system - general information
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 window 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 Information booklet, or consult your Volvo retailer 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 passenger compartment temperature sensor in the ECC control panel should
not be covered in any way as this could cause incorrect information to be sent to the ECC system.
Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the windows and sun roof (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 sun roof and use the recirculation function for several minutes to enable the air conditioning to
cool the compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the windows 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 disengaged 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 technician.
ProCarManuals.com

Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a
(HFC134a). This substance will not deplete the ozone layer. The system contains 2.2 lbs (1000 g) R134a and uses
PAG oil.
Climate system blower
The climate system blower will be automatically switched off when the engine is not running (even if the ignition key
is in position I or II) to avoid unnecessary battery drain. To activate the blower, turn the control to the desired setting.
Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower may come on automatically, and run for five
minutes, to remove condensation in the A/C evaporator.
pg. 51 Interior Air Quality system (option)
Interior Air Quality system (option)
Some cars 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 car. The air quality sensor detects increased levels of
contaminants in the outside air. When the air quality sensor detects contaminated outside air, the air intake closes and
the air inside the passenger compartment is recirculated, i.e. no outside air enters the car. The filter also cleans
recirculated passenger compartment air. When the Air quality sensor is activated, the LED AUT comes on in the
recirculation button
Operation:
Press
to activate the Air quality sensor (normal setting).
Or select one of three functions by pressing

1. Press
the LED AUT comes on.
The Air quality sensor is now activated.
2. Press
no LED is lighted.
Recirculation not activated.
3. Press
the LED MAN comes on. Recirculation is now activated. You can switch between these three functions
by repeatedly pressing
Keep the following in mind:
Make it a rule to have the air quality sensor activated at all times.
Recirculation is limited in cold climates to avoid misting up.
If misting occurs, you should deactivate the Air quality sensor.
If the windows mist up, you can also use the windshield and side window defroster functions. See page 48.
The filter should be changed at the intervals listed in the Warranty and Service Records Information booklet.
However, if the car is used in a severely contaminated environment, it may be necessary to change the filter more
frequently.
