However, if a fault is detected in the system:
The OWS indicator light will stay on
The SRS warning light will come on and stayon and a text message will be displayed.

WARNING
If a fault in the system is detected and indi-cated as described, be aware that the pas-senger's side front airbag will not deploy inthe event of a collision. In this case, the SRSsystem and Occupant Weight Sensor shouldbe inspected by a trained and qualified Volvoservice technician as soon as possible.

AVolvo recommends that children always be properly restrainedin appropriate child restraints in the rear seats. Do not assumethat the passenger's side front airbag is disabled unless thePASSENGER AIRBAG OFF indicator lamp is lit. Make sure thechild restraint is properly installed. If there is any doubt as to thestatus of the passenger's side front airbag, move the childrestraint to the rear seat.
The OWS is designed to enable (may inflate) thepassenger's side front airbag in the event of acollision anytime the system senses that a per-son of adult size is sitting properly in the frontpassenger's seat. The PASSENGER AIRBAGOFF indicator lamp will be off and remain off.
If a person of adult size is sitting in the front pas-senger's seat, but the PASSENGER AIRBAGOFF indicator lamp is on, it is possible that the

person isn't sitting properly in the seat. If thishappens:
Turn the vehicle off and ask the person toplace the backrest in an upright position.
Have the person sit upright in the seat, cen-tered on the seat cushion, with the person'slegs comfortably extended.
Restart the vehicle and have the personremain in this position for about two minutes.This will allow the system to detect that per-son and enable the passenger's frontal air-bag.
If the PASSENGER AIRBAG OFF indicatorlamp remains on even after this, the personshould be advised to ride in the rear seat.
This indicates limitations in OWS classificationcapability. It does not indicate OWS malfunction.

Modifications
If you are considering modifying your vehicle inany way to accommodate a disability, for exampleby altering or adapting the driver's or front pas-senger's seat(s) and/or airbag systems, pleasecontact Volvo at:

WARNING
No objects that add to the total weight onthe seat should be placed on the frontpassenger's seat. If a child is seated inthe front passenger's seat with any addi-tional weight, this extra weight couldcause the OWS system to enable the air-bag, which might cause it to deploy in theevent of a collision, thereby injuring thechild.
The seat belt should never be wrappedaround an object on the front passeng-er's seat. This could interfere with theOWS system's function.
The front passenger's seat belt shouldnever be used in a way that exerts morepressure on the passenger than normal.This could increase the pressure exertedon the weight sensor by a child, andcould result in the airbag being enabled,which might cause it to deploy in theevent of a collision, thereby injuring thechild.

WARNING
Keep the following points in mind withrespect to the OWS system. Failure tofollow these instructions could adverselyaffect the system's function and result inserious injury to the occupant of the frontpassenger's seat:
The full weight of the front seat passen-ger should always be on the seat cushion.The passenger should never lift him/herself off the seat cushion using thearmrest in the door or the center console,by pressing the feet on the floor, by sit-ting on the edge of the seat cushion, orby pressing against the backrest in a waythat reduces pressure on the seat cush-ion. This could cause OWS to disable thefront, passenger's side airbag.
WARNING
Do not place any type of object on thefront passenger's seat in such a way thatjamming, pressing, or squeezing occursbetween the object and the front seat,other than as a direct result of the correctuse of the Automatic Locking Retractor/Emergency Locking Retractor (ALR/ELR)seat belt.
No objects should be placed under thefront passenger's seat. This could inter-fere with the OWS system's function.

Driver/passenger-side airbags (p. 53)
Side airbags
The side airbags, on the driver's and passengersides, protect the chest and hip in a collision.
The side airbags are located in the front seats'outer backrest frames and help protect the driverand front seat passenger.
A collision of a sufficiently violent force will trig-ger the sensors and one or more side airbags willinflate. The side airbags inflate between the seatoccupant and the door panel to help cushion theinitial impact of the collision. The airbag deflateswhen compressed by the collision. The side air-bags are normally only deployed on the side ofthe vehicle impacted by the collision.

Inflatable curtain
The inflatable curtain, Inflatable Curtain (IC),helps to prevent the driver and passengers fromstriking their heads on the inside of the vehicleduring a collision.
The inflatable curtains are installed along bothsides of the inside of the roof and help protectoccupants in the vehicle's outer seats. ICAIRBAG is embossed on the panels.
A collision of a sufficiently violent force will trig-ger the sensors and the inflatable curtain willinflate.
WARNING
Volvo recommends contacting an authorizedVolvo workshop for repair. Incorrectly per-formed repairs to the inflatable curtain systemcould impair function and lead to seriousinjury.

WARNING
Never hang or attach heavy objects in thehandle in the ceiling. The hooks are onlyintended for lightweight garments (not forhard objects such as umbrellas).
Never screw or mount anything to the vehi-cle's headlining, door pillars or side panels.This could impair the intended protectiveproperties. Volvo recommends only usingVolvo original parts that are approved forplacement in these areas.

WARNING
If objects are loaded higher than the upperedge of the side windows, leave a 10 cm (4in.) space between the objects and the win-dow. Objects placed closer to this couldimpede the function of the inflatable curtainconcealed inside the headlining.

WARNING
Do not use child safety seats or childbooster cushions/backrests in the frontpassenger's seat. We also recommendthat children under 140 cm (4 feet7 inches) in height who have outgrownthese devices sit in the rear seat with theseat belt fastened.
Sedan models: Keep vehicle doors andtrunk locked and keep remote controlsout of a child's reach. Unsupervised chil-dren could lock themselves in an opentrunk and risk injury. Children should betaught not to play in vehicles.
On hot days, the temperature in the vehi-cle interior can rise very quickly. Exposureto these high temperatures for even ashort period of time can cause heat-rela-ted injury or death. Small children are par-ticularly at risk. Never leave children unat-tended in a vehicle.
Child seats should always be registered.

Volvo's recommendations
Why does Volvo believe that no child should sit inthe front seat of a vehicle? It's quite simple really.A front airbag is a very powerful device designed,by law, to help protect an adult.
Because of the size of the airbag and its speedof inflation, a child should never be placed in thefront seat, even if he or she is properly belted orstrapped into a child safety seat. Volvo has beenan innovator in the field of safety since it wasfounded. And we have no intention of resting onour laurels. But we need your help. Pleaseremember to put your children in the back seat,and buckle them up.
WARNING
A child restraint should never be reused if:
The vehicle has been involved in a colli-sion, no matter how minor
Its history is unknown
It is older than the manufacturer's expira-tion date

Volvo has some very specific
recommendations
Always wear your seat belt.
Airbags are a SUPPLEMENTAL safetydevice which, when used with a three-pointseat belt can help reduce serious injuriesduring certain types of accidents. Volvo rec-ommends that you do not disconnect the air-bag system in your vehicle.
Volvo strongly recommends that everyone inthe vehicle be properly restrained.
Volvo recommends that ALL occupants(adults and children) shorter than 140 cm(4 feet 7 inches) be seated in the rear seatof any vehicle with a front passenger side air-bag.
Drive safely!

Child restraint systems
Infant seat

The child restraint should be secured using athree-point seat belt, ISOFIX/LATCH anchors ortop tether anchors.
Convertible seat

WARNING
A child seat should never be used in the frontpassenger seat of any vehicle with a frontpassenger airbag - not even if the "Passengerairbag off" symbol near the rear-view mirror isilluminated. If the severity of an accident wereto cause the airbag to inflate, this could leadto serious injury or death to a child seated inthis position.
Booster cushion
