WARNING!
- Under-inflation is the most  common cause of tire failure and  may result in severe tire cracking,  tread separation, or
"blowout," with unexpected loss of vehicle control and  increased risk of injury.
- Under-inflated tires reduce the load carrying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degree temperature drop causes a
corresponding drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures frequently and  adjust them to the
proper pressure, which  can be  found on the vehicle's tire information placard  or certification label.
Checking tire pressure
Cold tires
Inflation  pressure should be  checked when the tires are cold.
The tires are considered to be cold when they have the same temperature as the surrounding (ambient) air.
This temperature is normally reached after the car has been parked for at least 3 hours.
pg. 100 Wheels and tires
After driving a  distance of approximately 1 mile (1.6 km), the tires are considered to be  hot. If you have to drive
farther than this  distance to pump your tire(s), check and  record the tire pressure first and  add  the appropriate air
pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tires are hot from  driving and  it
is normal for pressures to increase above recommended cold pressures. A hot tire at or below  recommended cold
inflation pressure could be  significantly under-inflated.
To check  inflation pressure:
1. 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 pressure
3. Replace the valve cap.
4. Repeat this  procedure for each tire, including the spare.
5. 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.
6. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities.
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 tire gauge.
• Some spare tires require higher inflation pressure than the other tires. Consult the tire inflation table  on page 101
 or
see the inflation pressure placard.

This limit is set by the tire manufacturer.
• Recommended tire inflation pressure: inflation pressure, established  by Volvo, which  is based on the type of tires

found on the tire inflation placard(s) located on the driver's side B-pillar or on the inside of the fuel filler  door on
Canadian models, and  in the tire inflation table  in this  chapter.

Vehicle loading
Properly  loading your vehicle will provide maximum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for determining your vehicle's weight
ratings, with or without a  trailer, from  the vehicle's Federal/Canadian Motor Vehicle Safety Standards
(FMVSS/CMVSS) label,  and  the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a  full tank of fuel and  all standard equipment. It does not include  passengers,
cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and  optional equipment. When towing, trailer hitch tongue load
is also part of cargo weight.
ProCarManuals.com 

NOTE: For trailer towing information, please refer  to the section "Towing a  trailer" on page 89.
Permissible  axle weight
The maximum allowable weight that can be  carried by a  single axle (front or rear).  These numbers  are shown on the
Federal/Canadian Motor Vehicle Safety Standards  (FMVSS/CMVSS) label.  The total load on each axle must  never
exceed its  maximum permissible weight.
Gross vehicle  weight (GVW)
The vehicle's curb weight +  cargo +  passengers.
NOTE:
• The location of the various  labels in your vehicle can be  found on page 144
.
• A table  listing  important weight limits for your vehicle can be  found on page 145
.
Steps for Determining Correct Load Limit
(1) Locate the statement "the  combined  weight of occupants and  cargo should never exceed XXX pounds" on your
vehicle's placard.
(2) Determine the combined  weight of the driver and  passengers that will be  riding in your vehicle.
(3) Subtract the combined  weight of the driver and  passengers from  XXX kilograms or XXX pounds.
(4) The resulting figure equals the available amount of cargo and  luggage load capacity. For example, if the "XXX"
amount equals 1400 lbs. and  there will be  five 150 lb. passengers in your vehicle, the amount of available cargo and
luggage load capacity is 650 lbs. (1400-750 (5 x 150) =  650 lbs.)
(5) Determine the combined  weight of luggage and  cargo being loaded on the vehicle. That weight may not safely
exceed the available cargo and  luggage load capacity calculated in Step 4.
(6) If your vehicle will be  towing a  trailer, load from  your trailer will be  transferred to your vehicle. Consult this
manual
1 to determine how this  reduces the available cargo and  luggage load capacity of your vehicle.
WARNING!
- Exceeding the permissible axle weight, gross vehicle weight, or any  other weight rating limits can cause tire
overheating resulting in permanent deformation or catastrophic failure.
- Do not use replacement  tires with lower load carrying capacities  than the tires that were  original equipment on the
vehicle because this  will lower the vehicle's GVW rating. Replacement tires with a  higher limit than the originals do
not increase the vehicle's GVW rating limitations.
