Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side frontairbag
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 (p. 33), andbe properly restrained for their size and weight.For child safety recommendations, see Childsafety (p. 46). The OWS works with sensors that are part of thefront passenger's seat and seat belt (p. 28). Thesensors are designed to detect the presence of aproperly seated occupant and determine if thepassenger's side front airbag should be enabled(may inflate) 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.

Park Assist Pilot (PAP) * –
introduction
The Park Assist Pilot provides assistance when parallel parking by measuring the parking spaceand turning the steering wheel.
Introduction
The off/on button shown is located on the center con- sole
Park Assist Pilot (PAP) is a semi-automatic sys- tem that provides assistance when parallel park-ing by:
• Finding a parking space and determining if itis big enough for the vehicle
• Helping to steer the vehicle into the parkingspace
Information about the actions required of thedriver is provided in the instrument panel in theform of symbols, images and text.
NOTE
If a trailer hitch is configured in the vehicle's electrical system, PAP will take the trailerhitch into consideration when determining thenecessary size of a parking space.
WARNING
• PAP does not function in all situations and is only intended to assist the driverwhen parallel parking.
• As the driver, you have full responsibilityfor parking the vehicle in a safe manner.

Park Assist Pilot (PAP)
* – function
PAP's function is to measure the parking space and to turn the steering wheel during the parallelparking procedure. The driver is responsible forfollowing the instructions shown in the instru- ment panel and for: shifting between R (Reverse)
and D (Drive) when required, regulating the vehi-
cle's speed, applying the brakes and stopping the vehicle. PAP can be activated in the following conditions:
• When the stability or ABS systems are not working actively
• The vehicle is not towing a trailer
• The vehicle's speed is below 30 mph(50 km/h)
How PAP works
PAP helps park the vehicle by:

Park Assist Pilot (PAP) * – limitations
The PAP parking procedure will be cancelled if.
• The vehicle's speed goes above approxi- mately 4 mph 7 km/h
• The driver moves the steering wheel
• If the stability or ABS systems are activated(e.g., if a wheel starts to spin because of aslippery road surface
If the system has been switched off, this will beindicated by a text message in the instrumentpanel.
NOTE
• PAP will not function correctly if its sen- sors are obstructed by dirt, snow, etc.
• In certain situations, PAP may not be ableto measure a parking space. This couldbe due to external sources of sound (e.g.,a vehicle's horn, tires on wet asphalt,pneumatic brakes, noise from a motorcy-cle's exhaust, etc.) emitting ultrasoundusing approximately the same frequen-cies as PAP.
Information to keep in mind
PAP is only intended to provide parallel parking assistance but may not be able to function fully inall situations. •
PAP's function is based on the way that thevehicles are parked behind and in front ofyour parking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims couldbe damaged by the curb during the parkingprocedure.
• PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with curved or irregular curbs. Be surethat your vehicle is parallel to the curb whenPAP measures the parking space.
• PAP may not be able to provide parkingassistance on narrow streets due to lack ofspace to maneuver the vehicle. In situationslike this, it may help to drive as close to theside of the road as possible where the park-ing space is located.
• Use only approved tires with the correct infla-tion pressure because this affects PAP'scapacity to provide parking assistance.Changing to a different approved tire sizemay affect PAP's parameters. Consult atrained and qualified Volvo service technician.
• Heavy rain or snow may inhibit PAP'scapacity to correctly measure a parkingspace.
• Do not use PAP if snow chains or a tempo-rary spare tire is being used.
• Do not use PAP if there are any objects pro-truding from the vehicle.
WARNING
• The front end of your vehicle may turn out toward oncoming traffic during the park-ing procedure.
• Objects located above the parking sen-sors' field of vision are not included whenPAP measures a parking space. For thisreason, PAP may turn into the parkingspace too soon. Avoid parking spaces ofthis type.
• The driver is always responsible for deter-mining if PAP has selected a suitableparking space.

Tires – storage and ageWhen storing complete wheels (tires mounted on rims), they should be suspended off the flooror placed on their sides on the floor.
New Tires
Remember that tires are perishable goods. As of 2000, the manufacturing week and year (Depart-ment of Transportation (DOT) stamp) will be indi-cated with 4 digits (e.g., 1513 means that the tireillustrated was manufactured during week 15 of2013).
Tire ageTires degrade over time, even when they are not being used. It is recommended that tires gener-ally be replaced after 6 years of normal service.Heat caused by hot climates, frequent high load-ing conditions or Ultra Violet (U.V.) exposure can accelerate the aging process. The temporary spare
1
should also be replaced at 6-year inter-
vals, even if it has never been used. A tire's age can be determined by the DOT stamp on the sidewall (see the illustration). A tire with e.g., visible cracks or discoloration should be replaced immediately.
Storing wheels and tiresWhen storing completes wheels (tires mountedon rims), they should be suspended off the flooror placed on their sides on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not besuspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should never be stored inclose proximity to solvents, gasoline, oils, etc.
WARNING
• The wheel and tire sizes for your Volvo are specified to meet stringent stabilityand handling requirements. Unapprovedwheel/tire size combinations can nega-tively affect your vehicle's stability andhandling.
• Any damage caused by installation ofunapproved wheel/tire size combinationswill not be covered by your new vehiclewarranty. Volvo assumes no responsibilityfor death, injury, or expenses that mayresult from such installations.

Tires – tread wear indicator The tires have wear indicator strips running across or parallel to the tread.
G021829
The letters TWI are printed on the side of the tire.
When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indi-cate that the tire should be replaced. Tires withless than 1/16" (1.6 mm) tread offer very poortraction. When replacing worn tires, it is recommended that the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of thesame make (manufacturer) will prevent alterationof the driving characteristics of the vehicle.

Tires – tire economy
A smooth driving style and correct inflation pres- sure can help prolong the tires' service life.
• Maintain correct tire pressure. The tire infla- tion table, see the tire inflation decal on thedriver's door opening.
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-tant.
• Unbalanced wheels impair tire economy anddriving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.

6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your vehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
WARNING
• Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.
