Points to keep in mindPAP is a parking aid only and the driver should always be prepared to take control and cancel aparking sequence. This can be due to one ormore of the following factors:
• PAP's function is based on the way that the vehicles 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 between 1.5-5 ft(0.5-1.5 m) from the side of the road wherethe parking 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 when using snow chainsand/or a temporary spare tire.
• 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.
Maintenance
Location of the PAP sensors
PAP uses the same sensors as the Park Assist system. To function correctly, these sensors mustbe cleaned regularly with water and a suitable carwashing detergent.

WHEELS AND TIRES
452temperature drop causes a corresponding drop of 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tiresare hot from driving and it is normal for pressuresto increase above recommended cold pressures.A hot tire at or below recommended cold inflationpressure could be significantly under-inflated.
Recommended inflation pressures
Tire inflation placard
A tire inflation pressure placard is located on the driver's side B-pillar (the structural member at theside of the vehicle, at the rear of the driver's dooropening). This placard indicates the designation
of the factory-mounted tires on your vehicle, aswell as load limits and inflation pressure.
NOTE
•
The placard shown indicates inflation pressure for the tires installed on thevehicle at the factory only.
• A certain amount of air seepage from thetires occurs naturally and tire pressurefluctuates with seasonal changes in tem-perature. Always check tire pressure reg-ularly.
•Use a tire gauge to check the tire inflation pressure, including the spare 3
, at least once
a month and before long trips. You are strongly urged to buy a reliable tire pressuregauge, as automatic service station gaugesmay be inaccurate.
• Use the recommended cold inflation pres-sure for optimum tire performance and wear.
• Under-inflation or over-inflation may causeuneven treadwear patterns.
Checking tire pressure1. Remove the cap from the valve on one tire,
then firmly press the tire gauge onto the valve. 2. Add air to reach the recommended air pres-
sure.
3. Replace the valve cap.
CAUTION
• After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded that could puncture the tire and cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including the spare.
NOTE
If you overfill the tire, release air by pushing on the metal stem in the center of the valve.Then recheck the pressure with your tiregauge.

Tire Pressure Monitoring System (TPMS) TPMS provides a warning if inflation pressure in one or more tires is too low. It also uses a sym-bol (called a telltale) that will flash for60 seconds and then glow steadily if there is asystem malfunction.
TPMS uses sensors mounted in the tire valves to check inflation pressure levels. When the vehicleis moving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmit infla-tion pressure data to a receiver located in thevehicle. If inflation pressure is too low, an indica-tor symbol will illuminate in the instrument paneland a text message will be displayed.
SymbolExplanation
The symbol illuminates to indicate low tire inflation pressure. If a malfunction occurs in the sys- tem, the tire pressure warning sym-bol will flash for approximately1 minute and then remain illumi-nated.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated tothe inflation pressure recommended by the vehi-cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale. When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panel
When the TPMS symbol illuminates, the following text messages may also be displayed:
•
Tire pressure low: the tire(s) affected will
also be specified.
•
Tire needs air now: the tire(s) affected will
also be specified.
•
Tire pressure system Service required.
If TPMS cannot determine which tire(s) have low inflation pressure, general messages may be dis-played, such as:
•
Tire pressure low Check tires
•Tire needs air now Check tires
TPMS sensors can be installed on the valve hole area, on the factory-installed wheels as well as onoptional ones.

WHEELS AND TIRES
458If a spare wheel or other wheel without a TPMS sensor is used, a fault message will appear in theinstrument panel after driving for a few minutes. After changing wheels, always check that the new wheels have TPMS sensors to avoid a sys-tem malfunction warning. TPMS does not replace the need for regular tire inspection and maintenance.
RecommendationsTPMS sensors should be mounted on all wheelsused with the vehicle, including winter wheels.
NOTE
•
If you change to tires with a different dimension than the factory-installed ones,the TPMS system must be reconfiguredfor these tires. This must be done by atrained and qualified Volvo service techni-cian.
• If a tire is changed, or if the TPMS sensoris moved to another wheel, the rubbervalve and valve core should be replaced.
• When installing TPMS sensors, the vehi-cle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.
