if the automatic locking retractor/emer- gency locking retractor (ALR/ELR) isactivated. Each seat belt (except for thedriver's) is equipped with an ALR func-tion, which is designed to keep the seatbelt taut when installing a childrestraint. ALR is activated when the seatbelt is pulled out as far as possible. Ifthis is done, a sound from the seat beltretractor will be audible, which is nor-mal. The seat belt can now only be fedinto the retractor, not pulled out. Thisfunction is automatically disabled whenthe seat belt is unbuckled and fullyretracted.

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 (p. 56)
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.
