Location of the passenger's side front airbagAs the movement of the seats' occupants compresses the airbags, some of the gas isexpelled at a controlled rate to provide bettercushioning. Both seat belt pretensioners alsodeploy, minimizing seat belt slack. The entireprocess, including inflation and deflation ofthe airbags, takes approximately one fifth of asecond. 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 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 thatno system can prevent all possibleinjuries that 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 consider-able force. During normal deploymentand depending on variables such asseating position, one may experienceabrasions, bruises, swellings, or otherinjuries as a result from 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 deploy during certain frontal or front-angular col-lisions, impacts, or decelerations,depending on the crash severity, angle,speed and object impacted. The airbagsmay also deploy in certain non-frontal collisions where rapid decelerationoccurs.
• The SRS (p. 31) sensors, which triggerthe front airbags, are designed to react toboth the impact of the collision and theinertial forces generated by it, and todetermine if the intensity of the collision issufficient for the seat belt pretensionersand/or airbags to be deployed.
However, not all frontal collisions activate the front airbags.
• If the collision involves a nonrigid object (e.g., a snow drift or bush), or a rigid,fixed object at a low speed, the front air-bags will 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.
WARNING
If any of the airbags have deployed:
• Do not attempt to drive the vehicle. Have it towed to a qualified repairfacility.
• If necessary seek medical attentIon.

WARNING
•Do not use child safety seats or child booster cushions/backrests in thefront passenger's seat. We also rec-ommend that occupants under 4 feet7 inches (140 cm) in height who haveoutgrown these devices sit in the rear seat with the seat belt fastened 1
.
• 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.

NOTE
•
Deployment of front airbags occurs only one time during an accident. In acollision where deployment occurs,the airbags and seat belt pretensionersactivate. Some noise occurs and asmall amount of powder is released.The release of the powder may appearas smoke-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 topresent a clear injury risk, the airbagsare triggered at partial capacity. If theimpact is more severe, the airbags aretriggered at full capacity.

Occupant Weight Sensor
The Occupant Weight Sensor (OWS) is designed to meet the regulatory requirementsof Federal Motor Vehicle Safety Standard(FMVSS) 208 and is designed to disable (willnot inflate) the passenger's side front airbagunder certain conditions.

Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side frontairbag
Volvo recommends that ALL occupants (adults and children) shorter than 4 feet7 inches (140 cm) be seated in the back seatof any vehicle with a front passenger side air-bag (p. 32), and be properly restrained fortheir size and weight. For child safety recom-mendations, see Child safety (p. 45). The OWS works with sensors that are part of the front passenger's seat and seatbelt (p. 28). The sensors are designed to detect the presence of a properly seatedoccupant and determine if the passenger'sside front airbag should be enabled (mayinflate) or disabled (will not inflate). 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 childis present in a forward-facing childrestraint that is installed according to themanufacturer's instructions,
• the system determines that a small childis present 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 OFF indicator 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 go on for up to 10 sec-onds while the system performs a self-diagnostic test.
However, if a fault is detected in the system:
• The OWS indicator light will stay on
• The SRS warning light (p. 31) will come on and stay on
• The message
Pass. Airbag OFF Service
urgent will be displayed in the informa-
tion display.
WARNING
If a fault in the system is detected and indicated as described, be aware that thepassenger's side front airbag will notdeploy in the event of a collision. In thiscase, the SRS system and OccupantWeight Sensor should be inspected by atrained and qualified Volvo service techni-cian as soon as possible.

•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 pas-senger's seat. This could interfere withthe OWS 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.

Components in the SIPS airbag systemThis SIPS airbag system consists of a gas generator, the side airbag modules built intothe outboard sides of both front seat back-rests, and electronic sensors/wiring.WARNING
•The SIPS airbag system is a supple- ment to the structural Side ImpactProtection System and the three-pointseat belt system. It is not designed todeploy during collisions from the frontor rear of the vehicle or in rollover sit-uations.
• The use of seat covers on the frontseats may impede SIPS airbag deploy-ment.
• No objects, accessory equipment orstickers may be placed on, attached toor installed near the SIPS airbag sys-tem or in the area affected by SIPS air-bag deployment.
• Never try to open or repair any compo-nents of the SIPS airbag system. Thisshould be done only by a trained andqualified Volvo service technician.
• In order for the SIPS airbag to provideits best protection, both front seatoccupants should sit in an uprightposition with the seat belt properly fas-tened.
• Failure to follow these instructions canresult in injury to the occupants of thevehicle in the event of an accident.
