NOTE
•Deployment of front airbags occurs onlyone time during an accident. In a collisionwhere deployment occurs, the airbagsand seat belt pretensioners activate.Some noise occurs and a small amountof powder is released. The release of thepowder may appear as smoke-like matter.This is a normal characteristic and doesnot indicate fire.
•Volvo's front airbags use special sensorsthat are integrated into the front seat beltbuckles. The point at which the airbagdeploys is determined by whether or notthe seat belt is being used, as well as theseverity of the collision.
•Collisions can occur where only one ofthe airbags deploys. If the impact is lesssevere, but severe enough to present aclear injury risk, the airbags are triggeredat partial capacity. If the impact is moresevere, the airbags are triggered at fullcapacity.
WARNING
•Do not use child safety seats or childbooster 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 with theseat belt fastened. See also the Occu-pant Weight Sensor information.
•Never drive with the airbags deployed.The fact that they hang out can impair thesteering of your vehicle. Other safety sys-tems can also be damaged.
•The smoke and dust formed when theairbags are deployed can cause skin andeye irritation in the event of prolongedexposure.
Should you have questions about any componentin the SRS system, please contact a trained andqualified Volvo service technician or Volvo cus-tomer support:

Disabling the passenger's side front
airbag
Volvo recommends that ALL occupants (adultsand children) shorter than 140 cm (4 feet7 inches) be seated in the back seat of any vehi-cle with a front passenger side airbag and beproperly restrained for their size and weight.
The OWS works with sensors that are part of thefront passenger's seat and seat belt. The sensorsare designed to detect the presence of a properly

seated occupant and determine if the passeng-er's side 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, orhas small/medium objects in the front seat,
•the system determines that an infant is pres-ent in a rear-facing infant seat that is instal-led according to the manufacturer's instruc-tions,
•the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufactur-er's instructions,
•the system determines that a small child ispresent in a booster seat,
•a front passenger takes his/her weight off ofthe seat for a period of time,
•a child or a small person occupies the frontpassenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stay on toremind you that the passenger's side front airbagis disabled. The PASSENGER AIRBAG OFF indi-cator lamp is located in the overhead console,near the base of the rearview mirror.

NOTE
When the ignition is switched on, the OWSindicator light will illuminate for several sec-onds while the system performs a self-diag-nostic 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 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.
WARNING
•Never try to open, remove or repair anycomponents 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 not bemodified in any way. This could reducepressure on the seat cushion, whichmight interfere with the OWS system'sfunction.

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.

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.

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.

WARNING
Volvo recommends contacting an authorizedVolvo workshop for repairs. Incorrectly per-formed repairs to the side airbag systemcould impair function and lead to seriousinjury.

WARNING
Do not place any objects in the area betweenthe outer edges of the seats and the doorpanels, as this could impair the function of theside airbags.
Volvo recommends only using seat coversapproved by Volvo. Other seat covers couldprevent the side airbags from functioningproperly.

WARNING
The side airbag is a supplement to the seatbelt. Always wear your seat belt.
