Seat belts
Seat belts should always be worn by all occu-pants of your vehicle. Children should be prop-erly restrained, using an infant, car, or boosterseat determined by age, weight and height.
Most states and provinces make it mandatory foroccupants of a vehicle to use seat belts.
Reversible seat belt pretensioners
Reversible seat belt pretensioners is a system inthe front seats that pulls the seat belts slightlytaut prior to a collision. This function helps posi-tion the front seat occupants to help improve theeffects of other safety systems, e.g., the airbagsystem.

Seat belt maintenance
Check periodically that the seat belts are in goodcondition. Use water and a mild detergent forcleaning. Check seat belt mechanism function asfollows: attach the seat belt and pull rapidly onthe strap.
WARNING
•Never repair the belt yourself; have thiswork done by a trained and qualifiedVolvo service technician only.
•Any device used to induce slack into theshoulder belt portion of the three-pointbelt system will have a detrimental effecton the amount of protection available toyou in the event of a collision.
•The seat back should not be tilted too farback. The shoulder belt must be taut inorder to function properly.
•Do not use child safety seats or childbooster cushions/backrests in the frontpassenger's seat. We also recommendthat children who have outgrown thesedevices sit in the rear seat with the seatbelt properly fastened.

Airbag system
As an enhancement to the three-point seat belts,your vehicle is equipped with an airbag system.

WARNING
•If the airbag warning light stays on afterthe engine has started or if it illuminateswhile you are driving, have the vehicleinspected by a trained and qualified Volvoservice technician as soon as possible.
•Never try to repair any component or partof the airbag systems yourself. Any inter-ference in the system could cause mal-function and serious injury. All work onthese systems should be performed by atrained and qualified Volvo service techni-cian.

WARNING
If your vehicle has become flood-damaged inany way (e.g., soaked carpeting/standingwater on the floor of the vehicle), do notattempt to start the vehicle. This may causeairbag deployment which could result in seri-ous injury. Have the vehicle towed to a trainedand qualified Volvo service technician forrepairs.
Before attempting to tow the vehicle:
1.Switch off the ignition for at least10 minutes and disconnect the battery.
2. Follow the instructions for manually over-riding the shiftlock system.
Deployed airbags
WARNING
If any of the airbags have deployed:
•Do not attempt to drive the vehicle. Haveit towed to a qualified repair facility.
•If necessary seek medical attentIon.
Driver/passenger side airbags
The front airbags supplement the three-pointseat belts. For these airbags to provide the pro-tection intended, seat belts must be worn at alltimes.
Driver's and passenger's side airbags

The front airbag system
The front airbag system includes gas generatorssurrounded by the airbags, and deceleration sen-sors that activate the gas generators, causing theairbags to be inflated with nitrogen gas.
As the movement of the seats' occupants com-presses the airbags, some of the gas is expelledat a controlled rate to provide better cushioning.Both seat belt pretensioners also deploy, mini-mizing seat belt slack. The entire process, includ-ing inflation and deflation of the airbags, takesapproximately one fifth of a second.

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 with the front seatbuckles. 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 4 feet 7 inches(140 cm) 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 4 feet 7 inches(140 cm) 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 result in system malfunction. Main-tenance or repairs should only be carriedout by an a trained and qualified Volvoservice 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.

PASSENGER 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 theperson isn't sitting properly in the seat. If thishappens:
•Turn the vehicle off and ask the person toplace the seatback 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 condition reflects limitations of the OWSclassification capability. It does not indicate OWSmalfunction.

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.
