WARNING
Never repair the belt yourself. Repairs should only be performed by a trainedand qualified Volvo service technician.
Any device used to induce slack intothe shoulder belt portion of the three-point belt system will have a detrimen-tal effect on the amount of protectionavailable in the event of a collision.
The seat back should not be tilted toofar back. The shoulder belt must betaut in order to function properly.
Do not use any type of child restraint inthe front passenger seat. We recom-mend that children who have outgrownthese devices sit in the rear seat withthe seat belt properly fastened.

Airbags
The vehicle is equipped with airbags and inflatable curtains for the driver and passen-gers.
WARNING
If the airbag warning light stays on after the engine has started or if it illu-minates while you are driving, have thevehicle inspected by a trained andqualified Volvo service technician assoon as possible.
Never attempt to alter or repair any ofthe vehicle's safety systems yourself.Incorrectly performed repairs to anysystem could impair function and leadto serious injury. All work on these sys-tems should be performed by a trainedand qualified Volvo service technician.
WARNING
If your vehicle has become water-damaged in any way (e.g., soaked floor mats/stand-ing water on the floor of the vehicle), donot attempt to start the engine. This maycause airbag deployment, which couldresult in serious injury. Volvo recommendstowing the vehicle directly to an authorizedVolvo workshop. Before attempting to tow the vehicle:
1. Switch off the ignition for at least 10
minutes and disconnect the battery.
2. Follow the instructions for manually overriding the shiftlock system.
Deployed airbags
WARNING
If any of the airbags have deployed:
Do not attempt to drive the vehicle. Have it towed to an authorized work-shop.
If necessary, seek medical attention.

As a supplement to the seat belts, the vehicle is equipped with driver and passenger sidefront airbags.
Driver/passenger side front airbags.
In a frontal collision, the airbags help protect the driver's and passenger's head, neck, faceand chest and the driver's knees and legs. A collision of a sufficiently violent force will trigger the sensors and one or more airbagswill inflate. The airbag helps cushion the initialimpact of the collision for the passenger. Theairbag deflates when compressed by the colli-sion. A small amount of powder will also bereleased from the airbag. This may appear tobe smoke and is normal. The entire process, from inflation to deflation of the airbag, occurs within tenths of a second.

ing on the crash severity, angle, speed and object impacted. The airbags may alsodeploy 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.

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.
Occupant Weight Sensor (OWS) indicator light
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 ifthe 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.

Volvo recommends that children always be properly restrained in appropriate child restraints in the rear seats.Do not assume that the passenger's side front airbag is dis-abled unless the PASSENGER AIRBAG OFF indicator lampis lit. Make sure the child restraint is properly installed. Ifthere is any doubt as to the status of the passenger's sidefront airbag, move the child restraint to the rear seat.
The OWS is designed to enable (may inflate) the passenger's side front airbag in the eventof a collision anytime the system senses that aperson of adult size is sitting properly in thefront passenger's seat. The PASSENGER AIR-BAG OFF indicator lamp will be off andremain off. If a person of adult size is sitting in the front passenger's seat, but the PASSENGER AIR- BAG OFF indicator lamp is on, it is possiblethat the person isn't sitting properly in theseat. If this happens:
Turn the vehicle off and ask the person toplace the backrest in an upright position.
Have the person sit upright in the seat,centered on the seat cushion, with theperson's legs comfortably extended.
Restart the vehicle and have the personremain in this position for about twominutes. This will allow the system todetect that person and enable the pas-senger's frontal airbag.
If the PASSENGER AIRBAG OFF indica-tor lamp remains on even after this, theperson should be advised to ride in therear seat.
This indicates limitations in OWS classifica-tion capability. It does not indicate OWS mal-function.ModificationsIf you are considering modifying your vehiclein any way to accommodate a disability, forexample by altering or adapting the driver's orfront passenger's seat(s) and/or airbag sys-tems, please contact Volvo at: In the United StatesVolvo Car USA, LLCCustomer Care Center
