The front airbag systemThe front airbag system includes gas genera- tors surrounded by the airbags, and decelera-tion sensors that activate the gas generators,causing the airbags to be inflated with nitro-gen gas. As the movement of the seats' occupants compresses the airbags, some of the gas isexpelled at a controlled rate to provide bettercushioning. The belt tensioners minimize slackin the seat belts and are activated for occu-pants wearing their seat belts. The entire proc-ess, from inflation to deflation of the airbag,occurs within tenths of a second. The location of the front airbags is indicated by SRS AIRBAG embossed on the steering
wheel pad and above the glove compartment,and by decals on both sun visors and on thefront and far right side of the dash. The driver's side front airbag is folded and
located in the steering wheel hub.The knee airbag is folded on the underside of
the dashboard on the driver's side. The text AIRBAG is embossed on the panel.
The passenger's side front airbag is folded
behind a panel located above the glove com-partment.WARNING
The airbags in the vehicle are designed to be a SUPPLEMENT to-not areplacement for-the three-point seatbelts. For maximum protection, wearseat belts at all times. Be aware that nosystem can prevent all possible injuriesthat may occur in an accident.
Never drive with your hands on thesteering wheel pad/airbag housing.
The front airbags are designed to helpprevent serious injury. Deploymentoccurs very quickly and with considera-ble force. During normal deploymentand depending on variables such asseating position, one may experienceabrasions, bruises, swellings, or otherinjuries as a result of deployment ofone or both of the airbags.
When installing any accessory equip-ment, make sure that the front airbagsystem is not damaged. Any interfer-ence in the system could cause mal-function.
Front airbag deployment
The front airbags are designed to deployduring certain frontal or front-angular colli-sions, impacts, or decelerations, depend-ing on the crash severity, angle, speed andobject impacted. The airbags may also deploy in certain non-frontal collisionswhere rapid deceleration occurs.
The airbag system's sensors, which triggerthe front airbags, are designed to deter-mine if the collision is powerful enough toactivate the belt tensioners and/or the air-bags.
However, not all frontal collisions activate thefront airbags. If the collision involves a nonrigid object (e.g., a snow drift or bush), or a rigid, fixedobject at a low speed, the front airbagswill not necessarily deploy.
Front airbags do not normally deploy in aside impact collision, in a collision fromthe rear or in a rollover situation.
The amount of damage to the bodyworkdoes not reliably indicate if the airbagsshould have deployed or not.

NOTE
Deployment of front airbags occurs only one time during an accident. In acollision where deployment occurs, theairbags and seat belt tensioners acti-vate. Some noise occurs and a smallamount of powder is released. Therelease of the powder may appear assmoke-like matter. This is a normalcharacteristic and does not indicatefire.
Volvo's front airbags use special sen-sors that are integrated with the frontseat buckles. The point at which theairbag deploys is determined bywhether or not the seat belt is beingused, as well as the severity of the col-lision.
Collisions can occur where only one ofthe airbags deploys. If the impact isless severe, but severe enough to pres-ent a clear injury risk, the airbags aretriggered at partial capacity. If theimpact is more severe, the airbags aretriggered at full capacity.
WARNING
Do not use child safety seats or child booster cushions/backrests in the frontpassenger's seat. We also recommendthat occupants under 140 cm (4 feet7 inches) in height who have outgrownthese devices sit in the rear seat withthe seat belt fastened. See also theOccupant Weight Sensor information.
Never drive with the airbags deployed.The fact that they hang out can impairthe steering of your vehicle. Othersafety systems can also be damaged.
The smoke and dust formed when theairbags are deployed can cause skinand eye irritation in the event of pro-longed exposure.

WARNING
Children must never be allowed in the front passenger's seat.
Occupants in the front passenger'sseat must never sit on the edge of theseat, sit leaning toward the instrumentpanel or otherwise sit out of position.
The occupant's back must be asupright as comfort allows and beagainst the seat back with the seat beltproperly fastened.
Feet must be on the floor, e.g., not onthe dash, seat or out of the window.
WARNING
No objects or accessory equipment, e.g. dashboard covers, may be placedon, attached to, or installed near the airbag cover (the area above the glovecompartment) or the area affected byairbag deployment.
There should be no loose articles, suchas coffee cups on the floor, seat, ordashboard area.
Never try to open the airbag cover onthe steering wheel or the passenger'sside dashboard. This should only bedone by a trained and qualified Volvoservice technician.
Failure to follow these instructions canresult in injury to the vehicle's occu-pants.

Occupant weight sensor
The Occupant Weight Sensor (OWS) is designed to meet the regulatory require-ments of Federal Motor Vehicle SafetyStandard (FMVSS) 208 and is designed todisable (will not inflate) the passenger's sidefront airbag under certain conditions.

Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and children) shorter than 140 cm(4 feet 7 inches) be seated in the back seat ofany vehicle with a front passenger side airbagand be properly restrained for their size andweight. The OWS works with sensors that are part of the front passenger's seat and seat belt. Thesensors are designed to detect the presence

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.
