Curb weightThe weight of the vehicle including a full tank
of fuel and all standard equipment. It does not
include passengers, cargo, or optional equip-
ment.
Capacity weightAll weight added to the curb weight, including
cargo and optional equipment. When towing,
trailer hitch tongue load is also part of cargo
weight.
NOTE
For trailer towing information, please refer to
the section "Towing a trailer", see
page 208.
Permissible axle weightThe 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 + passen-
gers.
NOTE
•The location of the various labels in your
vehicle can be found on page 268.
•A table listing important weight limits for
your vehicle can be found on page
273.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined
weight of occupants and cargo should
never exceed XXX pounds" on your vehi-
cle'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 luggageload capacity is 650 lbs. (1400 – 750
(5 × 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 manual1 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 over-
heating resulting in permanent defor-
mation 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 vehi-
cle's GVW rating. Replacement tires
with a higher limit than the originals do
not increase the vehicle's GVW rating
limitations.

251 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 appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire gra-
ded 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 signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked Cmay have poor traction performance. The trac-
tion 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.
TEMPERATUREThe temperature grades are AA (the highest),
A, B, and C, representing the tire's resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions 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 corre-
sponds 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 per-
formance on the laboratory test wheel than the
minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.
Snow chains, snow tires, studded tires
Snow chainsSnow 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.
•All Wheel Drive models: Snow chains
should only be installed on the front
wheels.

Consult your Volvo retailer for additional snow
chain information.
CAUTION
•Check local regulations regarding the
use of snow chains before installing.
•Use single-sided snow chains only.
•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.
Snow tires, studded tires2
Tires for winter use:
•Owners who live in or regularly commute
through areas with sustained periods of
snow or icy driving conditions are stronglyadvised 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. Fail-
ure 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 vehicle 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 regula-
tions restricting the use of studded winter
tires before installing such tires.
Temporary Spare
The spare tire in your vehicle3 is called a "Tem-
porary Spare".
Recommended tire pressure (see the placard
on the B-pillar or on the fuel filler door) should
be maintained irrespective of which position on
the vehicle 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 other than as a tem-
porary 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).
CAUTION
The vehicle must not be driven with wheels
of different dimensions or with a spare tire
other than the one that came with the vehi-
cle. The use of different size wheels can
seriously damage your car's transmission.
2Where permitted3Not on models equipped with the Tire sealing system.

Location of jack and tools
Spare wheelThe spare wheel (Temporary spare) is only
intended for temporary use. Replace the spare
wheel with a normal wheel as soon as possible.
The car's handling may be altered by the use
of the spare wheel. The correct tire pressure for
the spare wheel is stated in the tire pressure
tables on pages 247 and 247.
WARNING
Current legislation prohibits the use of the
“Temporary Spare” tire other than as a tem-
porary 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.
CAUTION
The vehicle must never be driven with more
than one temporary spare wheel.
The spare wheel is located in the spare wheel
well with the rim side down. There are two foam
blocks, one under the spare wheel and one
over/inside. The upper one contains all tools.
The same bolt runs through to secure the spare
wheel and the foam blocks.
Taking out the spare wheel1. Fold the rear edge of the floor mat forward.
2. Open the floor hatch.
3. Undo the retaining bolt.
4. Lift out the foam block with tools.
5. Lift out the spare wheel.
The other two blocks can remain in the wheel
well.
After useThe foam block and spare wheel must be
replaced in the reverse order. Note the arrow
on the upper foam block. It should point for-
ward.
NOTE
If the floor hatch is not completely closed,
the private locking feature (see page 59) will
not function.

ble) using the lug wrench in the tool
bag.With the vehicle still on the ground,
use the lug wrench to loosen the wheel
nuts 1/2 – 1 turns by exerting downward
pressure.
5. Turn the nuts counterclockwise to loosen.
6. There are two jack attachment points on
each side of the vehicle. 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 raisingthe vehicle, check that the jack is still cor-
rectly positioned in the attachment.
7. Raise the vehicle until the wheel to be
changed is lifted off the ground.
8. Unscrew the wheel nuts completely and
carefully remove the wheel so as not to
damage the threads on the studs.
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 vehicle supported by
a jack.
•Use the jack intended for the vehicle
when changing a tire. For any other job,
use stands to support the vehicle.
•Apply the parking brake and put the
gear selector in the Park (P) position.
•Block the wheels standing on the
ground, use rigid wooden blocks or
large stones.
•The jack should be kept well-greased
and clean, and should not be damaged.
•No objects should be placed between
the base of jack and the ground, or
between the jack and the attachment
bar on the vehicle.

If irritation persists, get medical atten-
tion.
Tire sealing system–temporarily
repairing a flat tire
G014338
Temporarily repairing a flat tire is done in two
stages:
•Stage 1: 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.
NOTE
Do not remove any foreign objects (nails,
etc.) from the tire before using the sealing
system.
•Stage 2: The tire’s inflation pressure is
checked and adjusted if necessary.
WARNING
•Never leave the tire sealing system
unattended when it is operating.
•Keep the tire sealing system away from
children.
•Be sure the vehicle is parked safely off
the road and away from moving traffic.
•Apply the parking brake.
Stage 1: Sealing the hole1. Open the cover on the tire sealing kit.2. Peel off the speed limit sticker and affix it
to the steering wheel hub where it will be
clearly visible to the driver.
3. Ensure that the on/off switch is in posi-
tion 0 (the 0 side of the switch should be
pressed down).
WARNING
Contact with the sealing compound may
cause skin irritation. If contact occurs, wash
the affected area immediately with soap and
water.
4. Unscrew the orange cover over the bottle
holder and unscrew the cap on the bottle
of sealing compound.
NOTE
Do not break the seal on the bottle. This
occurs automatically when the bottle is
screwed into the holder.
5. Screw the bottle into the bottle holder.

06 Maintenance and specifications

258
WARNING
The bottle is equipped with a catch to keep
it securely in place and help prevent sealing
compound leakage. Once in place, the bot-
tle cannot be unscrewed. This must be done
by a trained and qualified Volvo service
technician.
6. Remove the valve cap from the tire’s infla-
tion valve and screw the tire sealing sys-
tem’s hose connector onto the valve as
tightly as possible by hand.
7. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
8. Start the vehicle’s engine.
WARNING
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, or out-
doors, before using the system.
9. Start the tire sealing system’s compressor
by pressing the on/off switch to position I.
WARNING
•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.
NOTE
The air pressure gauge will temporarily
show an increase in pressure to approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.
10. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
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.
11. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.
12. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
13. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire.
