All Wheel Drive
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive (option), wh\
ich means that power is
distributed automatically between the front and rear wheels. Under norma\
l driving conditions, most of
the engine's power is directed to the front wheels. However, if there is\
any tendency for the front wheels
to spin, an electronically controlled coupling distributes power to the \
wheels that have the best traction.
Tire dimensions
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread
pattern, load-, speed-, traction-, temperature-, and treadwear rating. N\
ever drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire inflation pressure placards, located on the driver's side B-pil\
lar (the structural member at the side
of the vehicle, at the rear of the driver's door opening), or on the in\
side of the fuel filler door on
Canadian models.
Temporary Spare
The temporary spare tire is for temporary, lowspeed, short-distance use \
only. Replace it with a full-sized
tire as soon as possible. Do not drive on the temporary spare at speeds \
above 50 m.p.h. (80km/h) or for
distances greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

2006 VOLVO XC90
The tires have good road holding characteristics and offer good handling\
on dry and wet surfaces. It
should be noted however that the tires have been developed to give these\
features on snow/ice-free
surfaces.
Certain models are equipped with "all-season" tires, which provide a som\
ewhat higher degree of road
holding on slippery surfaces than tires without the "all-season" rating.\
However, for optimum road
holding on icy or snow-covered roads, we recommend suitable winter tires\
on all four wheels.
When replacing tires, be sure that the new tires are the same size desig\
nation, type (radial) and
preferably from the same manufacturer, on all four wheels. Otherwise the\
re is a risk of altering the car's
roadholding and handling characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed
on their sides on the floor.
Tires not mounted on rims should be stored on their sides or standing up\
right, but should not be
suspended.
Tread wear indicator
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should\
never be stored in close
proximity to solvents, gasoline, oils, etc.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the t\
read. 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 indicate that the tire should be replaced. Tires with less than 1/16\
" (1.6 mm) tread offer very poor
traction.
When replacing worn tires, it is recommended that the tire be identical \
in type (radial) and size as the
one being replaced. Using a tire of the same make (manufacturer) will \
prevent alteration of the driving
characteristics of the vehicle.

WARNING!
- The wheel and tire sizes for your Volvo are specified to meet stringen\
t stability and handling
requirements. Unapproved wheel/ tire size combinations can negatively af\
fect your vehicle's stability
and handling. Approved tire sizes are shown in the Tire inflation pressu\
re tables on
page 116.
- Any damage caused by installation of unapproved wheel/tire size combin\
ations will not be covered
by your new vehicle warranty. Volvo assumes no responsibility for death,\
injury, or expenses that
may result from such installations.
pg. 113 Wheels and tires
New tires
Remember that tires are perishable goods. As of 2000, the manufacturing \
week and year will be
indicated with 4 digits (e.g. 1502 means that the tire illustrated was \
manufactured during week 15 of
2002).
Tire age
Tires degrade over time, even when they are not being used, which can af\
fect their reliability and
roadholding characteristics. Therefore, all tires older than 6 years (i\
ncluding the spare tire and winter
tires) should be inspected by a qualified technician, regardless of app\
earance or mileage. Heat caused by
hot climates or frequent high loading conditions can accelerate the agin\
g process.
A tire's age can be determined by the DOT stamp on the sidewall (see th\
e illustration above).
A tire with e.g., visible cracks or discoloration should be replaced imm\
ediately.
Improving tire economy:
l Maintain correct tire pressure. See the tire pressure table on page 116.
l Drive smoothly: avoid fast starts, hard braking and tire screeching.
l Tire wear increases with speed.
l Correct front wheel alignment is very important.

pg. 115 Wheels and tires
After driving a distance of approximately 1 mile (1.6 km), the tires a\
re considered to be hot. If you have
to drive farther than this distance to pump your tire(s), check and re\
cord 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 col\
d pressures. A hot tire at or
below recommended cold inflation pressure could be significantly under-i\
nflated.
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 o\
bjects 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:
l If you overfill the tire, release air by pushing on the metal stem in th\
e center of the valve. Then
recheck the pressure with your tire gauge.
l Some spare tires require higher inflation pressure than the other tires.\
Consult the tire inflation table
on
page 116 or see the inflation pressure placard.

pg. 117 Wheels and tires
Tire Pressure Monitoring System (TPMS) - option on certain U.S. models\
only
The tire pressure monitoring system uses sensors mounted in the tire val\
ves to check inflation pressure
levels. When the vehicle is moving at a speed of 20 mph (30 km/h) or f\
aster, these sensors transmit
inflation pressure data to a receiver located in the vehicle.

8. U.S. DOT Tire Identification Number (TIN): This begins with the let\
ters "DOT" and indicates that the
tire meets all federal standards. The next two numbers or letters are th\
e plant code where it was
manufactured, the next two are the tire size code and the last four numb\
ers represent the week and year
the tire was built. For example, the numbers 317 mean the 31st week of 1\
997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The nu\
mbers in between are
marketing codes used at the manufacturer's discretion. This information \
helps a tire manufacturer
identify a tire for safety recall purposes.
9. Tire Ply Composition and Material Used: Indicates the number of plies\
indicates or the number of
layers of rubber-coated fabric in the tire tread and sidewall. Tire manu\
facturers also must indicate the
ply materials in the tire and the sidewall, which include steel, nylon, \
polyester, and others.
10. Maximum Load: Indicates the maximum load in pounds and kilograms tha\
t can be carried by the
tire. Refer to the vehicle's tire information placard or the safety cert\
ification label, located on the B-Pillar
or the driver's door or on the inside of the fuel filler door on Canadia\
n models, for the correct tire
pressure for your vehicle.
11. Treadwear, Traction, and Temperature grades: See
page 122 for more information.
12. Maximum permissible inflation pressure: the greatest amount of air p\
ressure that should ever be put
in the tire. This limit is set by the tire manufacturer.

Glossary of tire terminology
l Tire information placard: A placard showing the OE (Original Equipment) tire sizes, recommende\
d
inflation pressure, and the maximum weight the vehicle can carry.
l Tire Identification Number (TIN): A number on the sidewall of each tire providing information
about the tire brand and manufacturing plant, tire size and date of manu\
facturer.
l Inflation pressure: A measure of the amount of air in a tire.
l Standard load: A class of P-metric or Metric tires designed to carry a maximum load a\
t 35 psi [37
psi (2.5 bar) for Metric tires]. Increasing the inflation pressure bey\
ond this pressure will not increase the
tires load carrying capability.
l Extra load: A class of P-metric or Metric tires designed to carry a heavier maximu\
m load at 41 psi
[43 psi (2.9 bar) for Metric tires]. Increasing the inflation pressure\
beyond this pressure will not increase
the tires load carrying capability.
l kPa: Kilopascal, a metric unit of air pressure.

Snow chains, snow tire, studded tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l If accessory, aftermarket or "custom" tires and wheels are installed and\
are of a size different than the
original tires and wheels, chains in some cases CANNOT be used. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
l All Wheel Drive models: Snow chains should only be installed on the fron\
t wheels. Only chains
adapted for AWD models should be used.
NOTE: Consult your Volvo retailer for additional snow chain information.
CAUTION
- Check local regulations regarding the use of snow chains before instal\
ling.
- Always follow the chain manufacturer's installation instructions caref\
ully. Install chains as tightly as
possible and retighten periodically.
- Never exceed the chain manufacturer's specified maximum speed limit. (\
Under no circumstances
should you exceed 31 mph 50 km/h)
- Avoid bumps, holes or sharp turns when driving with snow chains.
- The handling of the vehicle can be adversely affected when driving wit\
h chains. Avoid fast or sharp
turns as well as locked wheel braking.

Tires for winter use:
- Owners who live in or regularly commute through areas with sustained p\
eriods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help ret\
ain the highest degree of traction.
- It is important to install winter tires on all four wheels to help ret\
ain traction during cornering, braking,
and accelerating. Failure to do so could reduce traction to an unsafe le\
vel or adversely affect handling.
- Do not mix tires of different design as this could also negatively aff\
ect overall tire road grip.
- Winter tires wear more quickly on dry roads in warm weather. They shou\
ld be removed when the
winter driving season has ended.

- Studded tires should be run-in 300-600 miles (500-1000 km) during wh\
ich the car should be driven as
smoothly as possible to give the studs the opportunity to seat properly \
in the tires. The tires should have
the same rotational direction throughout their entire lifetime.
NOTE: Please consult state or provincial regulations restricting the use of st\
udded winter tires before
installing such tires.
1. Where permitted
pg. 124 Wheels and tires
Temporary Spare
The spare tire in your car is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar or on the fu\
el filler door) should be
maintained irrespective of which position on the car the temporary spare\
tire is used on. In the event of
damage to this tire, a new one can be purchased from your Volvo retailer\
.
WARNING!
! Current legislation prohibits the use of the "Temporary Spare" tire ot\
her than as a temporary
replacement for a punctured tire. It must be replaced as soon as possibl\
e by a standard tire. Road
holding and handling may be affected with the "Temporary Spare" in use. \
Do not exceed 50 mph (80
km/h). Do not drive farther than 50 miles (80 km) on a temporary spar\
e tire.
CAUTION:
The car must not be driven with wheels of different dimensions or with a\
spare tire other than the one
that came with the car. The use of different size wheels can seriously d\
amage your car's transmission.
