Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side frontairbag
Volvo recommends that ALL occupants (adults and children) shorter than 4 feet7 inches (140 cm) be seated in the back seatof any vehicle with a front passenger side air-bag (p. 32), and be properly restrained fortheir size and weight. For child safety recom-mendations, see Child safety (p. 45). The OWS works with sensors that are part of the front passenger's seat and seatbelt (p. 28). The sensors are designed to detect the presence of a properly seatedoccupant and determine if the passenger'sside 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, 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 childis present in a forward-facing childrestraint that is installed according to themanufacturer's instructions,
• the system determines that a small childis present 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 OFF indicator 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 go on for up to 10 sec-onds while the system performs a self-diagnostic test.
However, if a fault is detected in the system:
• The OWS indicator light will stay on
• The SRS warning light (p. 31) will come on and stay on
• The message
Pass. Airbag OFF Service
urgent will be displayed in the informa-
tion display.
WARNING
If a fault in the system is detected and indicated as described, be aware that thepassenger's side front airbag will notdeploy in the event of a collision. In thiscase, the SRS system and OccupantWeight Sensor should be inspected by atrained and qualified Volvo service techni-cian as soon as possible.

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 isdisabled unless the PASSENGER AIRBAG OFF indicatorlamp is lit. Make sure the child restraint is properly instal-led. If there is any doubt as to the status of the passeng-er's side front airbag, move the child restraint to the rearseat.
The OWS is designed to enable (may inflate) the passenger's side front airbag in the eventof a collision anytime the system senses thata person of adult size is sitting properly in thefront passenger's seat. The PASSENGERAIRBAG OFF indicator lamp will be off andremain off. If a person of adult size is sitting in the frontpassenger'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 to place the seatback 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 condition reflects limitations of the OWS classification capability. It does not indicateOWS malfunction.
ModificationsIf you are considering modifying your vehiclein any way to accommodate a disability, forexample by altering or adapting the driver'sor front passenger's seat(s) and/or airbagsystems, please contact Volvo at: In the USA Volvo Cars of North America, LLC Customer Care Center

•No objects that add to the total weight on the seat should be placed on thefront passenger's seat. If a child isseated in the front passenger's seatwith any additional weight, this extraweight could cause the OWS systemto enable the airbag, which mightcause it to deploy in the event of a col-lision, thereby injuring the child.
• The seat belt should never be wrappedaround an object on the front pas-senger's seat. This could interfere withthe OWS system's function.
• The front passenger's seat belt shouldnever be used in a way that exertsmore pressure on the passenger thannormal. This could increase the pres-sure exerted on the weight sensor by achild, and could result in the airbagbeing enabled, which might cause it todeploy in the event of a collision,thereby injuring the child.
WARNING
• Keep the following points in mind with respect to the OWS system. Failure tofollow these instructions couldadversely affect the system's functionand result in serious injury to the occu-pant of the front passenger's seat:
• The full weight of the front seat pas-senger should always be on the seatcushion. The passenger should neverlift him/herself off the seat cushionusing the armrest in the door or thecenter console, by pressing the feet onthe floor, by sitting on the edge of theseat cushion, or by pressing againstthe backrest in a way that reducespressure on the seat cushion. Thiscould cause OWS to disable the front,passenger's side airbag.

Inflatable Curtain (IC)
The inflatable curtain is designed to help pro- tect the heads of the occupants of the frontseats and the occupant of the outboard rearseating positions in certain side impact colli-sions.
This system consists of inflatable curtains located along the sides of the roof liners,stretching from the center of both front sidewindows to the rear edge of the rear sidedoor windows. In certain side impacts, both the Inflatable
Curtain (IC) and the Side Impact Airbag Sys- tem (p. 39) (SIPS airbag) will deploy. The ICand the SIPS airbag deploy simultaneously.
NOTE
If the inflatable curtain deploys, it remains inflated for approximately 3 seconds.
WARNING
• The IC system is a supplement to the Side Impact Protection System. It isnot designed to deploy during colli-sions from the rear of the vehicle or inrollover situations.
• Never try to open or repair any compo-nents of the IC system. This should bedone only by a trained and qualifiedVolvo service technician.
• Never hang heavy items from the ceil-ing handles. This could impededeployment of the Inflatable Curtain.
• The cargo area and rear seat shouldnot be loaded to a level higher than2 in. (5 cm) below the upper edge ofthe rear side windows. Objects placedhigher than this level could impede thefunction of the Inflatable Curtain.
WARNING
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. Only adults should sit inthe front seats. Children must never beallowed in the front passenger seat, Childsafety (p. 45) for guidelines. Failure tofollow these instructions can result in injuryto the vehicle occupants in an accident.

WARNING
•Occupants in the front seats must never sit out of position. The occu-pant's back must be as upright ascomfort allows and be against the seatback with the seat belt properly fas-tened.
• If your vehicle has been involved in arear-end collision, the front seat back-rests must be inspected by a trainedand qualified Volvo service technician,even if the seats appear to be undam-aged. Certain components in theWHIPS system may need to bereplaced.
• Do not attempt to service any compo-nent in the WHIPS system yourself.
WARNING
•Boxes, suitcases, etc. wedged behind the front seats could impede the func-tion of the WHIPS system.
• If the rear seat backrests are foldeddown, cargo must be secured to pre-vent it from sliding forward against thefront seat backrests in the event of acollision from the rear. This couldinterfere with the action of the WHIPSsystem.
WARNING
Any contact between the front seat back- rests and the folded rear seat or a rear-facing child seat could impede the functionof the WHIPS system. If the rear seat isfolded down, the occupied front seatsmust be adjusted forward so that they donot touch the folded rear seat.

Child safety
Children should always be seated safely when traveling in the vehicle.
General informationVolvo recommends the proper use of restraintsystems (p. 47) for all occupants includingchildren. Remember that, regardless of ageand size, a child should always be properlyrestrained in a vehicle. Your vehicle is also equipped with ISOFIX/ LATCH attachments (p. 54), which make itmore convenient to install child seats. Some restraint systems for children are designed to be secured in the vehicle by lapbelts or the lap portion of a lap-shoulder belt.Such child restraint systems can help protectchildren in vehicles in the event of an acci-dent only if they are used properly. However,children could be endangered in a crash if thechild restraints are not properly secured in thevehicle. Failure to follow the installationinstructions for your child restraint can resultin your child striking the vehicle's interior in asudden stop. Holding a child in your arms is NOT a suitable substitute for a child restraint system. In anaccident, a child held in a person's arms canbe crushed between the vehicle's interior andan unrestrained person. The child could alsobe injured by striking the interior, or by beingejected from the vehicle during a suddenmaneuver or impact. The same can also hap-
