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

Whiplash Protection System (WHIPS)
The WHIPS system consists of specially designed hinges and brackets on the frontseat backrests designed to help absorb someof the energy generated in a collision from therear (when the vehicle is rear-ended).
In the event of a rear-end collision, the hinges and brackets of the front seat backrests aredesigned to change position slightly to allowthe backrest/head restraint to help supportthe occupant's head before moving slightlyrearward. This movement helps absorb someof the forces that could result in whiplash.
WARNING
•
The WHIPS system is designed to supplement the other safety systemsin your vehicle. For this system tofunction properly, the three-point seatbelt must be worn. Please be awarethat no system can prevent all possibleinjuries that may occur in an accident.
• The WHIPS system is designed tofunction in certain collisions from therear, depending on the crash severity,angle and speed.
