NOTE
•Deployment of front airbags occurs onlyone 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 into the front seat beltbuckles. 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.
Should you have questions about any componentin the SRS system, please contact a trained andqualified Volvo service technician or Volvo cus-tomer support:

Disabling the passenger's side front
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.

76 Integrated booster cushion*
1
The integrated booster cushion in the second
row center seating position helps ensure that a
child can sit comfortably and safely.
The integrated booster cushion has been spe-
cially designed to help safeguard children in the
rear seat when used with the vehicle's seat belts.
If using a booster cushion does not result in
proper positioning of the shoulder strap, then the
child should be placed in a properly secured child
restraint. The shoulder belt must never be placed
behind the child's back or under the arm.
Only used for children in the weight range
15-36 kg (33-80 lbs) and height range
97-137 cm (38-54 inches).
In Canada: 18 kg (40 lbs) is the minimum
weight requirement for a child using booster
cushions according to the Canadian regulation
CMVSS 213.4 Correct seating position: the seat belt is positioned
across the collarbone.
Before driving, make sure that:
• the booster cushion is locked into position
• the head restraint is set to the same height
as the child's head, so that, if possible, the
entire back of the child's head is covered
• the seat belt is taut, in contact with the
child's body and not twisted
• the seat belt is not positioned across the
child's throat or below the shoulder
• the lap section of the seat belt is placed low
over the child's hips to provide the best pro-
tection.
WARNING DEATH or SERIOUS INJURY can
occur
•
Follow all instructions on this
child restraint and in the vehicle's
owner's manual.
• Make sure the booster cushion is
securely locked before the child
is seated.
• Only use for children who weigh between
15-36 kg (33-80 lbs) and who are
between 97-137 cm (38-54 tum) in
height. In Canada: 18 kg (40 lbs) is the
minimum weight requirement for a child
using booster cushions according to the
Canadian regulation CMVSS 213.4
• Use only the vehicle's lap and shoulder
belt system when restraining the child in
this booster cushion.
• In the event of a collision while the inte-
grated booster cushion was occupied, the
entire booster cushion and seat belt must
be replaced. The booster cushion should
also be replaced if it is badly worn or
damaged in any way. This work should be
performed by a trained and qualified
Volvo service technician only. 1
