of a properly seated occupant and determine if the passenger's side front airbag should beenabled (may inflate) or disabled (will notinflate). The OWS will disable (will not inflate) the pas- senger's side front airbag when:
the front passenger's seat is unoccupied,or has small/medium objects in the frontseat,
the system determines that an infant ispresent in a rear-facing infant seat that isinstalled according to the manufacturer'sinstructions,
the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufac-turer's instructions,
the system determines that a small child ispresent in a booster seat,
a front passenger takes his/her weight offof the seat for a period of time,
a child or a small person occupies thefront passenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stayon to remind you that the passenger's sidefront airbag is disabled. The PASSENGERAIRBAG OFF indicator lamp is located in theoverhead console, near the base of the rear-view mirror.
NOTE
When the ignition is switched on, the OWS indicator light will illuminate for sev-eral seconds while the system performs aself-diagnostic test.
However, if a fault is detected in the system:
The OWS indicator light will stay on.
The SRS warning light will come on and stay on and a text message will be dis-played.
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, theSRS system and Occupant Weight Sensorshould be inspected by a trained and quali-fied Volvo service technician as soon aspossible.
WARNING
Never try to open, remove or repair any components in the OWS system. Thiscould cause the system to malfunction.Maintenance or repairs should only becarried out by an a trained and qualifiedVolvo service technician.
The front passenger's seat should notbe modified in any way. This couldreduce pressure on the seat cushion,which might interfere with the OWSsystem's function.

SAFETY

WARNING
No objects that add to the total weight on the seat should be placed on thefront passenger's seat. If a child isseated in the front passenger's seatwith any additional weight, this extraweight could cause the OWS systemto enable the airbag, which mightcause it to deploy in the event of a col-lision, thereby injuring the child.
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 exertsmore pressure on the passenger thannormal. This could increase the pres-sure exerted on the weight sensor by achild, and could result in the airbagbeing enabled, which might cause it todeploy in the event of a collision,thereby injuring the child.
WARNING
Keep the following points in mind with respect to the OWS system. Failure tofollow these instructions couldadversely affect the system's functionand result in serious injury to the occu-pant of the front passenger's seat.
The full weight of the front seat pas-senger should always be on the seatcushion. The passenger should neverlift him/herself off the seat cushionusing the armrest in the door or thecenter console, by pressing the feet onthe floor, by sitting on the edge of theseat cushion, or by pressing againstthe backrest in a way that reducespressure on the seat cushion. Thiscould cause OWS to disable the front,passenger's side airbag.
WARNING
Do not place any type of object on the front passenger's seat in such a waythat jamming, pressing, or squeezingoccurs between the object and thefront seat, other than as a direct resultof the correct use of the AutomaticLocking Retractor/Emergency LockingRetractor (ALR/ELR) seat belt.
No objects should be placed under thefront passenger's seat. This could inter-fere with the OWS system's function.

Side airbags
The side airbags, on the driver's and passen- ger sides, protect the chest and hip in a colli-sion.
The side airbags are located in the front seats' outer backrest frames and help protect thedriver and front seat passenger. A collision of a sufficiently violent force will trigger the sensors and one or more side air-bags will inflate. The side airbags inflate between the seat occupant and the door panel to help cushion the initial impact of the colli- sion. The airbag deflates when compressed by the collision. The side airbags are normally only deployed on the side of the vehicle impacted by the collision.
WARNING
Volvo recommends contacting an author- ized Volvo workshop for repairs. Incorrectlyperformed repairs to the side airbag sys-tem could impair function and lead to seri-ous injury.
WARNING
Do not place any objects in the area between the outer edges of the seats andthe door panels, as this could impair thefunction of the side airbags. Volvo recommends only using seat covers approved by Volvo. Other seat covers couldprevent the side airbags from functioningproperly.
WARNING
The side airbag is a supplement to the seat belt. Always wear your seat belt.

Child safety Children should always be seated safely when traveling in the vehicle.
General informationVolvo recommends the proper use of restraint systems for all occupants including children.Remember that, regardless of age and size, achild should always be properly restrained in avehicle. Your vehicle is also equipped with ISOFIX/ LATCH attachments, which make it more con-venient to install child seats. Some restraint systems for children are designed to be secured in the vehicle by lapbelts or the lap portion of a lap-shoulder belt.Such child restraint systems can help protectchildren in vehicles in the event of an accidentonly if they are used properly. However, chil-dren could be endangered in a crash if thechild restraints are not properly secured in thevehicle. Failure to follow the installationinstructions for your child restraint can resultin your child striking the vehicle's interior in asudden stop. Holding a child in your arms is NOT a suitable substitute for a child restraint system. In anaccident, a child held in a person's arms canbe crushed between the vehicle's interior andan unrestrained person. The child could alsobe injured by striking the interior, or by being ejected from the vehicle during a suddenmaneuver or impact. The same can also hap-pen if the infant or child rides unrestrained onthe seat. Other occupants should also beproperly restrained to help reduce the chanceof injuring or increasing the injury of a child. All states and provinces have legislation gov- erning how and where children should be car-ried in a vehicle. Find out the regulations exist-ing in your state or province. Recent accidentstatistics have shown that children are safer inrear seating positions than front seating posi-tions when properly restrained. A childrestraint system can help protect a child in avehicle. Here's what to look for when selectinga child restraint system: It should have a label certifying that it meets applicable Federal Motor Vehicle SafetyStandards (FMVSS 213) - or in Canada,CMVSS 213. Make sure the child restraint system is approved for the child's height, weight anddevelopment - the label required by the stand-ard or regulation, or instructions for infantrestraints, typically provide this information. In using any child restraint system, we urge you to carefully look over the instructions thatare provided with the restraint. Be sure youunderstand them and can use the device prop-erly and safely in this vehicle. A misused childrestraint system can result in increased inju-

64ries for both the infant or child and other occu- pants in the vehicle. When a child has outgrown the child safety seat, you should use the rear seat with thestandard seat belt fastened. The best way tohelp protect the child here is to place the childon a cushion so that the seat belt is properlylocated on the hips. Legislation in your state orprovince may mandate the use of a child seator cushion in combination with the seat belt,depending on the child's age and/or size.Please check local regulations. A specially designed and tested booster cush- ion and backrest can be obtained from yourVolvo retailer. See also the article "Integratedbooster cushion."
WARNING

Do not use child safety seats or child booster 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 withthe seat belt fastened.
Sedan models: Keep vehicle doors andtrunk locked and keep remote controlsout of a child's reach. Unsupervisedchildren could lock themselves in anopen trunk and risk injury. Childrenshould be taught not to play in vehi-cles.
On hot days, the temperature in thevehicle interior can rise very quickly.Exposure to these high temperaturesfor even a short period of time cancause heat-related injury or death.Small children are particularly at risk.Never leave children unattended in avehicle.
Child seats should always be registered.
Volvo's recommendationsWhy does Volvo believe that no child shouldsit in the front seat of a vehicle? It's quite sim-ple really. A front airbag is a very powerful device designed, by law, to help protect anadult. Because of the size of the airbag and its speed of inflation, a child should never be placed inthe front seat, even if he or she is properly bel-ted or strapped into a child safety seat. Volvohas been an innovator in the field of safetysince it was founded. And we have no inten-tion of resting on our laurels. But we needyour help. Please remember to put your chil-dren 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 expi-ration date

Volvo has some very specific recommendations
Always wear your seat belt.
Airbags are a SUPPLEMENTAL safety device which, when used with a three-point seat belt can help reduce seriousinjuries during certain types of accidents.Volvo recommends that you do not dis-connect the airbag system in your vehicle.
Volvo strongly recommends that everyonein the 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 sideairbag.
Drive safely!

Suitable child restraints should always be used when children travel in the vehicle.
Child restraint systems
Infant seat
There are three main types of child restraint systems: infant seats, convertible seats andbooster cushions. They are classified accord-ing to the child's age and size. The child restraint should be secured using a three-point seat belt, ISOFIX/LATCH anchorsor top tether anchors.
Convertible seat
WARNING
A child seat should never be used in the front passenger seat of any vehicle with afront passenger airbag - not even if the"Passenger airbag off" symbol near therear-view mirror is illuminated. If theseverity of an accident were to cause theairbag to inflate, this could lead to seriousinjury or death to a child seated in thisposition.
