Loading specifications
Properly loading your vehicle will provide maximum return of vehicle design perform-ance. Before loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or withouta trailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weightThe weight of the vehicle including a full tankof fuel and all standard equipment. It doesnot include passengers, cargo, or optionalequipment.
Capacity weightAll weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
Permissible axle weightThe maximum allowable weight that can becarried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-gers.
NOTE
•The location of the various labels in your vehicle, see Label information(p. 367).
• A table listing important weight limitsfor your vehicle, see Weights (p. 372).
Loading specifications – load limit
The load limit of your vehicle is the combined weight of the occupants and cargo.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo shouldnever exceed XXX pounds" on your vehi-cle's placard.
2. Determine the combined weight of the driver and passengers that will be ridingin your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kilo-grams or XXX pounds.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle,the amount of available cargo and lug-gage load capacity is 650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceedthe available cargo and luggage loadcapacity calculated in Step 4.

6. If your vehicle will be towing a trailer, loadfrom your trailer will be transferred to your vehicle.
WARNING
•Exceeding the permissible axle weight, gross vehicle weight, or any otherweight rating limits can cause tireoverheating resulting in permanentdeformation or catastrophic failure.
• Do not use replacement tires withlower load carrying capacities than thetires that were original equipment onthe vehicle because this will lower thevehicle's GVW rating. Use only tireswith the correct load carrying capacity.Consult your Volvo retailer for informa-tion.
Tire specifications – terminology
The following is a glossary of tire-related terms. The tire suppliers may have additional mark- ings, notes or warnings such as standardload, radial tubeless, etc.
• Tire information placard
: A placard
showing the OE (Original Equipment) tire sizes, recommended inflation pressure,and the maximum weight the vehicle cancarry.
• Tire Identification Number (TIN)
: A
number on the sidewall of each tire pro-viding information about the tire brandand manufacturing plant, tire size anddate 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 maximumload at 35 psi [37 psi (2.5 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetires load carrying capability.
• Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maxi-mum load at 41 psi [43 psi (2.9 bar) forMetric tires]. Increasing the inflation pres-sure beyond this pressure will notincrease the tire's load carrying capabil-ity. •
kPa
: Kilopascal, a metric unit of air pres-
sure.
• 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 perim-
eter of the tire that contacts the roadwhen mounted on the vehicle.
• Rim
: The metal support (wheel) for a tire
or a tire and tube assembly upon whichthe tire beads are seated.
• Maximum load rating
: a figure indicating
the maximum load in pounds and kilo-grams that can be carried by the tire. Thisrating is established by the tire manufac-turer.
• Maximum permissible inflation pressure
: the greatest amount of air
pressure that should ever be put in the tire. This limit is set by the tire manufac-turer.
• Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires thatare mounted on a vehicle at the factory.This information can be found on the tireinflation placard(s) located on the driver's

WARNING
The bottle is equipped with a catch to keep it securely in place and help preventsealing compound leakage. Once in place,the bottle cannot be unscrewed. This mustbe done by a trained and qualified Volvoservice technician.
5. Remove the valve cap from the tire’sinflation valve and screw the tire sealing system’s hose connector onto the valveas tightly as possible by hand.
6. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
NOTE
Be sure that none of the other 12-volt sockets is being used while the compres-sor is in operation.
7. Start the vehicle’s engine.
WARNING
The vehicle´s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be sure thevehicle is parked in a well ventilated place,or outdoors, before using the system.
8. Start the tire sealing system’s compres-sor by pressing the on/off switch to posi- tion I.
WARNING
• Never stand next to the tire being infla- ted when the compressor is in opera-tion.
• If cracks, bubbles, etc. form on the tire,switch off the compressor immediately.
• If there is visible damage to the sidewallor the rim, the tire cannot be repaired.The vehicle should not be driven if thisoccurs. Contact a towing service orVolvo On Call Roadside Assistance ifapplicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approxi-mately 88 psi (6 bar) while the sealingcompound is being pumped into the tire.The pressure should return to a normallevel after approximately 30 seconds.
9. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch off the compressor briefly to get aclear reading from the pressure gauge.
