WARNING
If your vehicle has become water-damaged inany way (e.g., soaked floor mats/standingwater on the floor of the vehicle), do notattempt to start the engine. This may causeairbag deployment, which could result in seri-ous injury. Volvo recommends towing thevehicle directly to an authorized Volvo work-shop.
Before attempting to tow the vehicle:
1.Switch off the ignition for at least 10minutes and disconnect the battery.
2. Follow the instructions for manually over-riding the shiftlock system.

Deployed airbags
WARNING
If any of the airbags have deployed:
Do not attempt to drive the vehicle. Haveit towed to an authorized workshop.
If necessary, seek medical attention.

Driver/passenger-side airbags
As a supplement to the seat belts, the vehicle isequipped with driver and passenger side frontairbags.
Driver/passenger side front airbags.
In a frontal collision, the airbags help protect thedriver's and passenger's head, neck, face andchest and the driver's knees and legs.
A collision of a sufficiently violent force will trig-ger the sensors and one or more airbags willinflate. The airbag helps cushion the initial impactof the collision for the passenger. The airbagdeflates when compressed by the collision. Asmall amount of powder will also be releasedfrom the airbag. This may appear to be smokeand is normal. The entire process, from inflationto deflation of the airbag, occurs within tenths ofa second.
NOTE
The sensors react differently depending onthe circumstances of the accident andwhether or not the seat belt is used. Thisapplies to all belt positions.
There may therefore be accident situations inwhich only one (or none) of the airbags aredeployed. The sensors monitor the impact ofthe collision and react accordingly to deployone, several or no airbags.

WARNING
The seat belt and the airbag work together. Ifthe seat belt is not used or is used incorrectly,the airbag may not provide the intended pro-tection in a collision.
To help prevent injury in the event the airbagis deployed, passengers should sit as uprightas possible, with their feet on the floor andtheir backs against the seat backrest.

WARNING
Volvo recommends contacting an authorizedVolvo workshop for repairs. Incorrectly per-formed repairs to the airbag system couldimpair function and lead to serious injury.

The front airbag system
The front airbag system includes gas generatorssurrounded by the airbags, and deceleration sen-

sors that activate the gas generators, causing theairbags to be inflated with nitrogen gas.
As the movement of the seats' occupants com-presses the airbags, some of the gas is expelledat a controlled rate to provide better cushioning.The belt tensioners minimize slack in the seatbelts and are activated for occupants wearingtheir seat belts. The entire process, from inflationto deflation of the airbag, occurs within tenths ofa second.
The location of the front airbags is indicated bySRS AIRBAG embossed on the steering wheelpad and above the glove compartment, and bydecals on both sun visors and on the front andfar right side of the dash.
The driver's side front airbag is folded andlocated in the steering wheel hub.
The knee airbag is folded on the underside ofthe dashboard on the driver's side. The textAIRBAG is embossed on the panel.
The passenger's side front airbag is foldedbehind a panel located above the glove compart-ment.

WARNING
The airbags in the vehicle are designed tobe a SUPPLEMENT to-not a replacementfor-the three-point seat belts. For maxi-mum protection, wear seat belts at alltimes. Be aware that no system can pre-vent all possible injuries that may occur inan accident.
Never drive with your hands on the steer-ing wheel pad/airbag housing.
The front airbags are designed to helpprevent serious injury. Deployment occursvery quickly and with considerable force.During normal deployment and depend-ing on variables such as seating position,one may experience abrasions, bruises,swellings, or other injuries as a result ofdeployment of one or both of the airbags.
When installing any accessory equipment,make sure that the front airbag system isnot damaged. Any interference in the sys-tem could cause malfunction.

Front airbag deployment
The front airbags are designed to deploy dur-ing certain frontal or front-angular collisions,impacts, or decelerations, depending on thecrash severity, angle, speed and objectimpacted. The airbags may also deploy in
certain non-frontal collisions where rapiddeceleration occurs.
The airbag system's sensors, which triggerthe front airbags, are designed to determineif the collision is powerful enough to activatethe belt tensioners and/or the airbags.
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, fixed objectat a low speed, the front airbags will not nec-essarily deploy.
Front airbags do not normally deploy in aside impact collision, in a collision from therear 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 onlyone time during an accident. In a collisionwhere deployment occurs, the airbagsand seat belt tensioners activate. Somenoise occurs and a small amount of pow-der is released. The release of the pow-der 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 childbooster 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 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.

airbag
Volvo recommends that ALL occupants (adultsand children) shorter than 140 cm (4 feet7 inches) 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 thefront 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 OFFindicator 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 OWSindicator 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 stayon 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 anycomponents 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 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 onthe 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 withrespect 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 thefront 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 airbags
The side airbags, on the driver's and passengersides, protect the chest and hip in a collision.
The side airbags are located in the front seats'outer backrest frames and help protect the driverand front seat passenger.
A collision of a sufficiently violent force will trig-ger the sensors and one or more side airbags willinflate. The side airbags inflate between the seatoccupant and the door panel to help cushion theinitial impact of the collision. The airbag deflateswhen compressed by the collision. The side air-bags are normally only deployed on the side ofthe vehicle impacted by the collision.

WARNING
Volvo recommends contacting an authorizedVolvo workshop for repairs. Incorrectly per-formed repairs to the side airbag systemcould impair function and lead to seriousinjury.

WARNING
Do not place any objects in the area betweenthe outer edges of the seats and the doorpanels, as this could impair the function of theside airbags.
Volvo recommends only using seat coversapproved by Volvo. Other seat covers couldprevent the side airbags from functioningproperly.

WARNING
The side airbag is a supplement to the seatbelt. Always wear your seat belt.
