NOTE
•Deployment of front airbags occurs only one 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 child booster 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.

Occupant weight sensor
The Occupant Weight Sensor (OWS) is designed to meet the regulatory requirements ofFederal Motor Vehicle Safety Standard (FMVSS)208 and is designed to disable (will not inflate)the passenger's side front airbag under certainconditions.

Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and 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 the front 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 OFF
indicator 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 OWS indicator 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 stay on 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 any components 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.

SAFETY

WARNING
•No objects that add to the total weight on the 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 with respect 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 the front 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 impact airbags
As an enhancement to the structural side impact protection built into your vehicle, it is also equip-ped with Side Impact Protection System (SIPS)airbags.
The SIPS airbag system is designed to help increase occupant protection in the event of cer-tain side impact collisions. The SIPS airbags aredesigned to deploy only during certain side-impact collisions, depending on the crashseverity, angle, speed and point of impact.
NOTE
SIPS airbag deployment (one airbag) occurs only on the side of the vehicle affected by theimpact. The airbags are not designed todeploy in all side impact situations.
Components in the SIPS airbag systemThis SIPS airbag system consists of a gas gener- ator, the side airbag modules built into the out-board sides of both front seat backrests, andelectronic sensors/wiring.WARNING
• The SIPS airbag system is a supplement to the structural Side Impact ProtectionSystem and the three-point seat belt sys-tem. It is not designed to deploy duringcollisions from the front or rear of thevehicle or in rollover situations.
• The use of seat covers on the front seatsmay impede SIPS airbag deployment.
• No objects, accessory equipment or stick-ers may be placed on, attached to orinstalled near the SIPS airbag system orin the area affected by SIPS airbagdeployment.
• 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 provide itsbest protection, both front seat occupantsshould sit in an upright position with theseat belt properly fastened.
• Failure to follow these instructions canresult in injury to the occupants of thevehicle in the event of an accident.

Inflatable curtainsThe inflatable curtain is designed to help protect the heads of the occupants of the front seatsand the occupant of the outboard rear seatingpositions in certain side impact collisions.
This system consists of inflatable curtains located along the sides of the roof liners, stretching fromthe center of both front side windows to the rearedge of the rear side door windows. In certain side impacts, both the Inflatable Cur-
tain (IC) and the side Impact Airbag System (SIPS airbag) will deploy. The IC and the SIPSairbag deploy simultaneously.
WARNING
• Never try to open or repair any compo- nents of the IC system. This should bedone only by a trained and qualified Volvoservice technician.
• Never hang heavy items from the ceilinghandles. This could impede deploymentof the Inflatable Curtain.
• The cargo area and rear seat should notbe loaded to a level higher than 4 in.(10 cm) below the upper edge of the rearside windows. Objects placed higher thanthis level could impede the function ofthe Inflatable Curtain.
• In order for the IC to provide its best pro-tection, both front seat occupants andboth outboard rear seat occupants shouldsit in an upright position with the seat beltproperly fastened; adults using the seatbelt and children using the proper childrestraint system.

Child restraints
Suitable child restraints should always be used when children travel in the vehicle.
Child restraint systems
Infant seat
There are three main types of child restraint sys- tems: infant seats, convertible seats and boostercushions. They are classified according to thechild's age and size. The child restraint should be secured using a three-point seat belt, ISOFIX/LATCH anchors ortop tether anchors.
Convertible seat
WARNING
A child seat should never be used in the front passenger seat of any vehicle with a frontpassenger airbag – not even if the "Passen-ger airbag off" symbol near the rear-view mir-ror is illuminated (on vehicles equipped withOccupant Weight Sensor). If the severity of anaccident were to cause the airbag to inflate,this could lead to serious injury or death to achild seated in this position.
