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

WARNING
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 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 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.

Child safety Children should always be seated safely when traveling in the vehicle.
General informationVolvo recommends the proper use of restraint systems for all occupants including children.Remember that, regardless of age and size, achild should always be properly restrained in avehicle. Your vehicle is also equipped with ISOFIX/ LATCH attachments, which make it more con-venient 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 accidentonly if they are used properly. However, chil-dren 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 being

SAFETY
64ejected from the vehicle during a sudden maneuver or impact. The same can also hap-pen if the infant or child rides unrestrained onthe seat. Other occupants should also beproperly restrained to help reduce the chanceof injuring or increasing the injury of a child. All states and provinces have legislation gov- erning how and where children should be car-ried in a vehicle. Find out the regulations exist-ing in your state or province. Recent accidentstatistics have shown that children are safer inrear seating positions than front seating posi-tions when properly restrained. A childrestraint system can help protect a child in avehicle. Here's what to look for when selectinga child restraint system: It should have a label certifying that it meets applicable Federal Motor Vehicle SafetyStandards (FMVSS 213) - or in Canada,CMVSS 213. Make sure the child restraint system is approved for the child's height, weight anddevelopment - the label required by the stand-ard or regulation, or instructions for infantrestraints, typically provide this information. In using any child restraint system, we urge you to carefully look over the instructions thatare provided with the restraint. Be sure youunderstand them and can use the device prop-erly and safely in this vehicle. A misused childrestraint system can result in increased inju-
ries for both the infant or child and other occu-pants in the vehicle. When a child has outgrown the child safety seat, you should use the rear seat with thestandard seat belt fastened. The best way tohelp protect the child here is to place the childon a cushion so that the seat belt is properlylocated on the hips. Legislation in your state orprovince may mandate the use of a child seator cushion in combination with the seat belt,depending on the child's age and/or size.Please check local regulations. A specially designed and tested booster cush- ion and backrest can be obtained from yourVolvo retailer. See also the article "Integratedbooster cushion."
WARNING

Do not use child safety seats or child booster cushions/backrests in the frontpassenger's seat. We also recommendthat children under 140 cm (4 feet7 inches) in height who have outgrownthese devices sit in the rear seat withthe seat belt fastened.
Sedan models: Keep vehicle doors andtrunk locked and keep remote controlsout of a child's reach. Unsupervisedchildren could lock themselves in anopen trunk and risk injury. Childrenshould be taught not to play in vehi-cles.
On hot days, the temperature in thevehicle interior can rise very quickly.Exposure to these high temperaturesfor even a short period of time cancause heat-related injury or death.Small children are particularly at risk.Never leave children unattended in avehicle.
Child seats should always be registered.
Volvo's recommendationsWhy does Volvo believe that no child shouldsit in the front seat of a vehicle? It's quite sim-ple really. A front airbag is a very powerful

device designed, by law, to help protect an adult. Because of the size of the airbag and its speed of inflation, a child should never be placed inthe front seat, even if he or she is properly bel-ted or strapped into a child safety seat. Volvohas been an innovator in the field of safetysince it was founded. And we have no inten-tion of resting on our laurels. But we needyour help. Please remember to put your chil-dren in the back seat, and buckle them up.
WARNING
A child restraint should never be reused if:
The vehicle has been involved in a colli- sion, no matter how minor
Its history is unknown
It is older than the manufacturer's expi-ration date
Volvo has some very specific recommendations

Always wear your seat belt.
Airbags are a SUPPLEMENTAL safety device which, when used with a three-point seat belt can help reduce seriousinjuries during certain types of accidents.Volvo recommends that you do not dis-connect the airbag system in your vehicle.
Volvo strongly recommends that everyonein the vehicle be properly restrained.
Volvo recommends that ALL occupants(adults and children) shorter than 140 cm(4 feet 7 inches) be seated in the rear seatof any vehicle with a front passenger sideairbag.
Drive safely!

Child restraint systems
Infant seat
There are three main types of child restraint systems: infant seats, convertible seats andbooster cushions. They are classified accord-ing to the child's age and size. The child restraint should be secured using a three-point seat belt, ISOFIX/LATCH anchorsor top tether anchors.

Convertible seat
WARNING
A child seat should never be used in the front passenger seat of any vehicle with afront passenger airbag - not even if the"Passenger airbag off" symbol near therear-view mirror is illuminated. If theseverity of an accident were to cause theairbag to inflate, this could lead to seriousinjury or death to a child seated in thisposition.
Booster cushion
WARNING
Always refer to the child restraint manufac- turer's instructions for detailed informationon securing the restraint.
WARNING
When not in use, keep the child restraint system secured or remove itfrom the passenger compartment tohelp prevent it from injuring passen-gers in the event of a sudden stop orcollision.
A small child's head represents a con-siderable part of its total weight and itsneck is still very weak. Volvo recom-mends that children up to age 4 travel,properly restrained, facing rearward. Inaddition, Volvo recommends that chil-dren should ride rearward facing, prop-erly restrained, as long as possible.
NOTE
Prolonged installation and use of the child restraint may damage the vehicle's interior.Volvo recommends using the kick guardaccessory to help protect the vehicle'sinterior.
Automatic Locking Retractor/ Emergency Locking Retractor (ALR/ELR)
To make child seat installation easier, each seat belt (except for the driver's belt) is equip-ped with a locking mechanism to help keepthe seat belt taut.

When attaching the seat belt to a child seat:
1. Attach the seat belt to the child seataccording to the child seat manufacturer's instructions.
2. Pull the seat belt out as far as possible.
3. Insert the seat belt latch plate into the buckle (lock) in the usual way.
4. Release the seat belt and pull it taut around the child seat.
A sound from the seat belt retractor will be audible at this time and is normal. The belt willnow be locked in place. This function is auto-matically disabled when the seat belt isunlocked and the belt is fully retracted.
WARNING
Do not use child safety seats or child booster cushions/backrests in the frontpassenger's seat. We also recommend thatchildren who have outgrown these devicessit in the rear seat with the seat belt prop-erly fastened.
Child restraint registration and recallsChild restraints could be recalled for safety reasons. You must register your child restraintto be reached in a recall. To stay informedabout child safety seat recalls, be sure to fill out and return the registration card thatcomes with new child restraints. Child restraint recall information is readily available in both the U.S. and Canada.
