LOADING AND STORAGE
204•
Place heavier cargo at the bottom of the load.
• Secure the cargo correctly with appropriatetie-down equipment.
• Check periodically that the load carriers andload are properly secured.
• Remember that the vehicle's center of gravityand handling change when you carry a loadon the roof.
• The vehicle's wind resistance and fuel con-sumption will increase with the size of theload.
• Drive smoothly. Avoid rapid starts, fast cor-nering and hard braking.
CAUTION
The optional moonroof should not be opened while load carriers are installed on the vehicle.
See the article "Weights" for information about the maximum permissible load that can be trans-ported on the roof.

DRIVER SUPPORT
* Option/accessory.343
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 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 between1.5-5.0 ft (0.5-1.5 m) from the side of theroad where the 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
In order for PAP to function correctly, these sen- sors must be cleaned regularly with water and asuitable car washing detergent.

sidewall (see the illustration). A tire with e.g., visi- ble cracks or discoloration should be replacedimmediately.
Tire economy
•
Maintain correct tire pressure.
• 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.
Tire rotationYour vehicle has no required tire rotation. Tirewear is affected by a number of factors such astire inflation, ambient temperature, driving style,etc.
NOTE
•If the tires are rotated, they should only be moved from front to rear or vice versa.They should never be rotated left toright/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000 miles(5,000 km) and thereafter at 6,000-mile(10,000-km) intervals. Some customersfind that tire rotation may help to getextra mileage from tire life.
• Tire rotation should only be performed iffront/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Storing wheels and tiresWhen storing complete wheels (tires mounted on rims), they should be suspended off the floor orplaced 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.

Tire sidewall designations
The following information can be found on a tire's sidewall.
Federal law mandates that tire manufacturers place standardized information on the sidewall ofall tires (see the illustration). The vehicle has been certified with certain combi- nations of wheels and tires. The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire desig- nation is an example only and that this par-
ticular tire may not be available on your vehi- cle.
1. 215 : the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its width
in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example, a
load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum
speed at which the tire is designed to bedriven for extended periods of time, carryinga permissible load for the vehicle, and withcorrect inflation pressure. For example, Hindicates a speed rating of 130 mph(210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because they arenot required by law.
7. M+S or M/S = Mud and Snow, AT = All Ter-
rain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and Material Used :
Indicates the number of plies indicates or thenumber of layers of rubber-coated fabric inthe tire tread and sidewall. Tire manufactur-ers also must indicate the ply materials in thetire and the sidewall, which include steel,nylon, polyester, and others.
3 Self-supporting run flat tires may not be available on all models

Maximum Load : Indicates the maximum
load in pounds and kilograms that can be carried by the tire. Refer to the vehicle's tireinformation placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperaturegrades .
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This limit is setby the tire manufacturer.
Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certifiedand should be at least equivalent to the vehicle'stop speed. Winter tires, with our without studs, are excep- tions and may use a lower SS. When winter tiresare installed, the vehicle may not be driven fasterthan the tires' SS. The vehicle's speed should always be determined by the posted speed limit and traffic and roadconditions, not the tire's SS. The following table indicates the maximum per- missible speed for each SS.
Speed Symbol
M 81 mph (130 km/h)
Q 100 mph (160 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (300 km/h)

Tire terminology The following is a glossary of tire-related terms.
The tire suppliers may have additional markings, notes or warnings such as standard load, radialtubeless, etc.• Tire information placard
: A placard show-
ing the OE (Original Equipment) tire sizes,recommended inflation pressure, and themaximum weight the vehicle can carry.
• Tire Identification Number (TIN)
: A number
on the sidewall of each tire providing infor-mation about the tire brand and manufactur-ing plant, tire size and date of manufacturer.
• Inflation pressure
: A measure of the
amount of air in a tire.
• Standard load
: A class of P-metric or Metric
tires designed to carry a maximum load at35 psi [37 psi (2.5 bar) for Metric tires].Increasing the inflation pressure beyond thispressure will not increase the tires load car-rying capability.
• Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maximumload at 41 psi [43 psi (2.9 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetire's load carrying capability.
• kPa
: Kilopascal, a metric unit of air pressure.
• PSI
: Pounds per square inch, a standard unit
of air pressure. •
B-pillar
: The structural member at the side
of the vehicle behind the front door.
• Bead area of the tire
: Area of the tire next
to the rim.
• Sidewall of the tire
: Area between the bead
area and the tread.
• Tread area of the tire
: Area of the perime-
ter of the tire that contacts the road whenmounted on the vehicle.
• Rim
: The metal support (wheel) for a tire or a
tire and tube assembly upon which the tirebeads are seated.
• Maximum load rating
: a figure indicating
the maximum load in pounds and kilogramsthat can be carried by the tire. This rating isestablished by the tire manufacturer.
• Maximum permissible inflation pressure
:
the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby the tire manufacturer.
• Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires that aremounted on a vehicle at the factory. Thisinformation can be found on the tire inflationplacard(s) located on the driver's side B-pillarand in the tire inflation table in this chapter.
• Cold tires
: The tires are considered to be
cold when they have the same temperatureas the surrounding (ambient) air. This tem- perature is normally reached after the vehiclehas been parked for at least 3 hours.

Tire direction of rotation
Incorrectly mounted tires impair the car's braking properties and ability to force aside rain, snowand slush.
The arrows shows the direction of rotation of the tire
• The tires with the most tread should always be on the rear axle (to help reduce the risk ofskidding).
• When switching between summer and wintertires, mark the tires to indicate where theywere mounted on the car, e.g., LF = left front,RR = right rear
• Tires with tread designed to roll in only onedirection are marked with an arrow on thesidewall.
• Contact a trained and qualified Volvo servicetechnician if you are unsure about the treaddepth.

•Tires (p. 440)
Tread wear indicator
The tires have wear indicator strips running across or parallel to the tread.
The letters TWI are printed on the side of the tire. When approximately 1/16" (1.6 mm) is left onthe 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 help preventalteration of the driving characteristics of thevehicle.
