NOTE: The placards shown indicate inflation pressure for the tires installed on the car at the factory only.
Use a tire gauge to check the tire inflation pressure, including the spare, at least once a month and before long trips.
You are strongly urged to buy a reliable tire pressure gauge, as automatic service station gauges may be inaccurate.
Use the recommended cold inflation pressure for optimum tire performance and wear.
Under-inflation or over-inflation may cause uneven treadwear patterns.
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. 129 Wheels and tires
Tire inflation
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:
Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve.
Add air to reach the recommended air pressure
Replace the valve cap.
Repeat this procedure for each tire, including the spare.
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.
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 130 or
see the inflation pressure placard.

Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
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.
3. R: Radial tire.
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 be driven for extended periods of
time, carrying a permissible load for the vehicle, and with correct inflation pressure. For example, H indicates a speed
rating of 130 mph (210 km/h).
NOTE: This information may not appear on the tire because it is not required by law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and indicates that the tire meets
all federal standards. The next two numbers or letters are the plant code where it was manufactured, the next two are
the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers
317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of
2001. The numbers 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 manufacturers 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 that can be carried by the tire. Refer to the
vehicle's tire information placard or the safety certification label, located on the B-Pillar or the driver's door or on the
inside of the fuel filler door on Canadian models, for the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperature grades : See page 134
for more information.
12. 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 manufacturer.

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 188.
A table listing important weight limits for your vehicle can be found on page 189.
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.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature
A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and many depart significantly from the norm due to variation in driving habits,
maintenance practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The traction
ProCarManuals.com
Page 121 of 182
grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of cornering (turning)
traction.
WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of
cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a minimum level of performance that all
passenger vehicle tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.
WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and tire
failure.

Snow chains, snow tire, studded tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
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. Sufficient clearances between chains and brakes, suspension and
body components must be maintained.
Some strap -on type chains will interfere with brake components and therefore CANNOT be used. Consult your
Volvo retailer for additional snow chain information.
CAUTION!
Check local regulations regarding the use of snow chains before installing.
Always follow the chain manufacturer's installation instructions carefully. 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 with chains. Avoid fast or sharp turns as well
as locked wheel braking.

Tires for winter use:
ProCarManuals.com
Page 122 of 182
Owners who live in or regularly commute through areas with sustained periods of snow or icy driving conditions are
strongly advised to fit suitable winter tires to help retain the highest degree of traction.
It is important to install winter tires on all four wheels to help retain traction during cornering, braking, and
accelerating. Failure to do so could reduce traction to an unsafe level or adversely affect handling.
Do not mix tires of different design as this could also negatively affect overall tire road grip.
Winter tires wear more quickly on dry roads in warm weather. They should be removed when the winter driving
season has ended.
Studded tires should be run-in 300-600 miles (500-1000 km) during which 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 studded winter tires before installing such
tires.

Wheel nuts
Wheel nuts
There are two different types of wheel nut, depending on whether the wheels are steel or aluminum.
Steel rims - low nut
Steel rims are normally secured using the low type of nut, although steel rims may also use the high type.
WARNING!
Never use the short type of nut for aluminium wheels. This could cause the wheel to come loose.
Aluminum wheels - high nut
Only the high type of nut can be used for aluminum wheels. This is considerably different from other types of nut
because it has a rotating conical thrust washer.
NOTE: This nut can also be used on steel wheels.
Lockable wheel nut
If steel wheels with lockable wheel nuts are used in combination with wheel covers, the lockable wheel nut must be
fitted to the stud nearest the air valve. The wheel cover cannot otherwise be installed on the wheel.

the car. The use of different size wheels can seriously damage your car's transmission.
Location of the optional spare wheel and tools
The spare wheel is packed in a storage bag and is located under the panel in the floor of the trunk. On cars with a
spare wheel, the jack and lug wrench are secured in a foam plastic block placed in the center of the wheel. The
retaining straps securing the spare wheel is attached to two eyelets in the floor of the spare wheel's storage
compartment.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. It must be replaced as soon as possible 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 spare tire.
Accessing the spare wheel:
Open the hatch in the floor of the trunk.
Release the retaining straps and lift out the spare wheel in its storage bag.
Open the zipper on the storage bag and lift out the spare wheel.
The wheel that was replaced by the temporary spare tire can then be placed in the storage bag.

Positioning the jack
There are two jack attachment points on each side of the car.
Position the jack correctly in the attachment (see illustration above) and crank while simultaneously guiding the base
of the jack to the ground. The base of the jack must be flat on a level, firm, non-slippery surface.
Before raising the car, check that the jack is still correctly positioned in the attachment.
WARNING!
The jack must correctly engage the jack attachment.
Be sure the jack is on a firm, level, non-slippery surface.
Never allow any part of your body to be extended under a car supported by a jack.
Use the jack intended for the car when changing a tire. For any other job, use stands to support the car.
Apply the parking brake and put the gear selector in the (P)ark position.
Block the wheels standing on the ground, use rigid wooden blocks or large stones.
The jack should be kept well-greased.
Removing a wheel:
Raise the vehicle until the wheel to be changed is lifted off the ground.
Unscrew the wheel nuts completely and carefully remove the wheel so as not to damage the threads on the studs.
Installing a wheel
Clean the contact surfaces on the wheel and hub.
Lift the wheel and place it on the hub.
Install the wheel nuts and tighten hand -tight. Using the lug wrench, tighten crosswise until all nuts are snug.
Lower the vehicle to the ground and alternately tighten the bolts crosswise to 62 ft. lbs. (85 Nm).
Install the wheel cap (where applicable).

Tire sealing system
ProCarManuals.com
Page 126 of 182
Your vehicle is equipped with a tire sealing system that enables you to temporarily seal a hole in the tread surface and
re-inflate a flat tire, or to adjust a tire's inflation pressure.
The tire sealing kit is stowed behind the ski hatch in the center of the rear seat backrest.
The jack, and lug wrench are secured in a foam plastic block located under the floor panel in the trunk.
The system consists of an air compressor, an integrated container for the sealing compound, wiring to connect the
system to the vehicle's electrical system via one of the 12-volt sockets, and a hose used to connect the system to the
tire's inflation valve.
NOTE:
The tire sealing system is only intended to seal holes on the tire's tread area, not the sidewall.
Tires with large holes or tears cannot be repaired with the tire sealing system.
WARNING!
After using the tire sealing system, the vehicle should not be driven farther than approximately 120 miles (200
km). Have the tire replaced as soon as possible.
The vehicle should not be driven faster than 50 mph (80 km/h) while using a tire that has been temporarily
repaired with the tire sealing system.
After using the tire sealing system, drive carefully and avoid abrupt steering maneuvers and sudden stops.

Temporarily repairing a flat tire
Before using the tire sealing system, observe the following:
WARNING!
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system kit away from children.
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be
sure the vehicle is parked in a well ventilated place before using the system.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Do not remove any foreign objects (nails, etc.) from the tire.
Temporarily repairing a flat tire is done in two stages.
In the first stage, the hole is sealed by pumping sealing compound into the tire. The car is then driven a short
distance to distribute the sealing compound in the tire.
In the second stage, the tire's inflation pressure is checked and adjusted if necessary.
Stage 1: Sealing the hole
Peel off the speed limit sticker (1) and affix it to the steering wheel hub where it will be clearly visible to the driver.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Pull out the electrical wire (5) and hose (4) from the side compartment (3).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Release the safety catch (6) and turn the orange colored section of the sealing kit (7), which holds the sealing
compound container, 90 degrees until it clicks into the vertical position.
Start the vehicle's engine.
Start the tire sealing system's compressor by pressing the switch (2) to position I.
NOTE: The air pressure gauge (9) will temporarily show an increase in pressure to approximately 88 psi (6 bar) while
the sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately
one minute.
pg. 143 Wheels and tires
Tire sealing system
WARNING!
ProCarManuals.com
Page 128 of 182
Contact with the sealing compound may cause skin irritation. If contact occurs, wash the affected area immediately
with soap and water.
Never stand next to the tire being inflated when the compressor is in operation. If cracks, bubbles, etc. form on the
tire, switch off the compressor immediately. If there is visible damage to the sidewall or the rim, the tire cannot be
repaired. The vehicle should not be driven if this occurs. Contact a towing service or Volvo On Call Roadside
Assistance if applicable.
Within seven minutes, inflate the tire to between 22 - 50 psi (1.8 - 3.5 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge (9).
CAUTION!
If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn off the compressor. In this
case, the hole is too large to be sealed and the vehicle should not be driven.
Disconnect the electrical wire from the 12-volt socket.
Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
Fold down the orange section of the tire sealing system to its original (horizontal) position and press the safety catch
into place.
Safely stow the tire sealing system kit in a convenient place as it will soon be used again to check the tire's inflation
pressure.
Immediately drive the vehicle for approximately 2 miles (3 km) to distribute the sealing compound in the tire.
WARNING!
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the car
in a safe place. Recheck the tire for bumps, cracks, or other visible damage, and recheck its inflation pressure. If the
pressure is below 16 psi (1.3 bar), do not continue driving. Have the vehicle towed to a workshop or Volvo retailer.
Stage 2: Checking inflation pressure
Park the car in a safe place.
Ensure that the orange switch (2) is in position 0 (the 0 side of the switch should be pressed down).
Remove the valve cap from the tire's inflation valve and screw the hose connector onto the valve as tightly as
possible by hand.
Connect the electrical wire to the nearest 12-volt socket in the vehicle.
Start the vehicle's engine.
Check the tire's inflation pressure on the gauge (9).
NOTE: In dark conditions, switching on the tire sealing system's compressor will illuminate the pressure gauge.
Inflate the tire to the correct pressure as indicated in the tire inflation tables on page 116. If the tire needs to be
inflated, start the tire sealing system's compressor. If necessary, release air from the tire by pressing the vent button (8).
Turn off the compressor (press switch 2 to the 0 position) when the correct inflation pressure has been reached.
