Volvo recommends that ALL occupants (adults and children) shorter than 4 feet 7 inches(140 cm) be seated in the back seat of any vehi-cle with a front passenger side airbag and beproperly restrained for their size and weight.

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 OFF
indicator 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 OWS indicator 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 stay on 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 any components in the OWS system. Thiscould result in system malfunction. Main-tenance or repairs should only be carriedout by an a trained and qualified Volvoservice 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.

NOTE
When switching to higher octane fuel or changing gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticeable.
Fuel FormulationsDo not use gasoline that contains lead as a knock inhibitor, and do not use lead additives.Besides damaging the exhaust emission controlsystems on your vehicle, lead has been stronglylinked to certain forms of cancer. Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, take pre-cautions. These may include: •standing upwind away from the filler nozzle while refueling.
• refueling only at gas stations with vaporrecovery systems that fully seal the mouth ofthe filler neck during refueling.
• wearing neoprene gloves while handling afuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze duringwinter months, do not add solvents, thickeners, orother store-bought additives to your vehicle'sfuel, cooling, or lubricating systems. Overuse maydamage your engine, and some of these additivescontain organically volatile chemicals. Do notneedlessly expose yourself to these chemicals.
WARNING
Never carry a cell phone that is
switched on
while refueling your vehicle. If the phone rings, this may cause a spark that could ignite gaso-line fumes, resulting in fire and injury.
