General information
Tire inflation
Check tire inflation pressure regularly.
Tables listing the recommended inflation pressure for your vehicle can b\
e found on
pages 154 and 155.
A tire inflation pressure placard is also located on the driver's side B\
pillar (the structural member at the
side of the vehicle, at the rear of the driver's door opening). This pl\
acard indicates the designation of the
factory-mounted tires on your vehicle, as well as load limits and inflat\
ion pressure.
NOTE: The placards shown indicate inflation pressure for the tires installed \
on the vehicle at the factory
only.
l Use a tire gauge to check the tire inflation pressure, including the spa\
re, at least once a month and
before long trips. You are strongly urged to buy a reliable tire pressur\
e gauge, as automatic service

station gauges may be inaccurate.
l Use the recommended cold inflation pressure for optimum tire performance\
and wear.
l Under-inflation or over-inflation may cause uneven treadwear patterns.
WARNING!
l 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.
l Under-inflated tires reduce the load carrying capacity of your vehicle. \
When weather temperature changes occur, tire inflation pressures also ch\
ange. A 10- degree temperature
drop causes a corresponding drop of 1 psi (7 kPa) in inflation pressur\
e. 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
A certain amount of air seepage from the tires occurs naturally and tire\
pressure fluctuates with seasonal
changes in temperature. Always check tire pressure regularly.
Cold tires
Inflation pressure should be checked when the tires are cold.
pg. 153 Wheels and tires
General information
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 vehicle has been parked f\
or at least 3 hours.

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:
- 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 ob\
jects 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:
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 154 or see the inflation pressure placard.

Tire Pressure Monitoring System (TPMS) - option
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 approximately 20 mph (\
30 km/h) or faster, these
sensors transmit inflation pressure data to a receiver located in the ve\
hicle.
USA - FCC ID: MRXTG315AM04
This device complies with part 15 of the FCC rules. Operation is subject\
to the following conditions:
(1) This device may not cause harmful interference, and (2) this dev\
ice must accept any interference
received, including interference that may cause undesired operation.
When low inflation pressure is detected, TPMS will light up the tire pre\
ssure warning light (
) (also
referred to as a telltale) in the instrument panel, and will display a \
message in the text window. The
wording of this message is determined by the degree of inflation pressur\
e loss.
NOTE: If a fault occurs in TPMS, the tire pressure warning light will flash f\
or approximately 1 minute
and TIRE PRESS SYST SERVICE REQUIRED will be displayed.

Each tire, including the spare (if provided), should be checked monthl\
y when cold and inflated to the
inflation pressure recommended by the vehicle manufacturer on the vehicl\
e placard or tire inflation
pressure label. (If your vehicle has tires of a different size than the\
size indicated on the vehicle placard
or tire inflation pressure label, you should determine the proper tire i\
nflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire p\
ressure monitoring system
(TPMS) that illuminates a low tire pressure telltale when one or more \
of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale illuminates, \
you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driv\
ing on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. \
Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle's handling an\
d stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenanc\
e, and it is the driver's
responsibility to maintain correct tire pressure, even if under-inflatio\
n has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to\
indicate when the system is
not operating properly. The TPMS malfunction indicator is combined with \
the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for appro\
ximately one minute and then
remain continuously illuminated. This sequence will continue upon subseq\
uent vehicle start-ups as long
as the malfunction exists. When the malfunction indicator is illuminated\
, the system may not be able to
detect or signal low tire pressure as intended. TPMS malfunctions may oc\
cur for a variety of reasons,
including the installation of replacement or alternate tires or wheels o\
n the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction tellta\
le after replacing one or
more tires or wheels on your vehicle to ensure that the replacement or a\
lternate tires and wheels allow
the TPMS to continue to function properly.
NOTE:
l TPMS indicates low tire pressure but does not replace normal tire mainte\
nance. For information on
correct tire pressure, please refer to the table on
page 154, or consult your Volvo retailer.
Erasing warning messages

- Drive the vehicle for several minutes at a speed of 20 mph (30 km/h)\
or faster.
This will erase the warning text and the warning light will go out.
WARNING!
Incorrect inflation pressure could lead to tire failure, resulting in a \
loss of control of the
vehicle.
Changing wheels with TPMS
Please note the following when changing or replacing the factory install\
ed TPMS wheels/ tires on the
vehicle:
l Only the factory-mounted wheels are equipped with TPMS sensors in the va\
lves.
l If the vehicle is equipped with a temporary spare tire, this tire does n\
ot have a TPMS sensor.
l If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SY\
ST SERVICE
REQUIRED will be displayed each time the vehicle is driven above 25 mph \
(40 km/h) for 10 minutes or
more.
l Once TPMS sensors are properly installed, the warning message should not\
reappear.
l Volvo recommends that TPMS sensors be fitted on all wheels used on the v\
ehicle. Volvo does not
recommend moving sensors back and forth between sets of wheels.
CAUTION!
When inflating tires with TPMS valves, press the pump's mouthpiece strai\
ght onto the valve to help
avoid bending or otherwise damaging the valve.
Adjusting (recalibrating) TPMS
1
TPMS can be adjusted, or recalibrated, in order to help adapt the system\
to different inflation pressures,
for example when transporting heavy loads. To do so:
- Switch off the engine.
- Inflate the tires to the desired pressure.
- Turn the ignition key to position I or II.
- Turn the thumbwheel on the left steering wheel lever until the text TI\
RE PRESSURE CALIBRATION
is displayed.
- Press in and hold the Reset button (see the illustration on
page 50) until TIRE PRESSURE
CALIBRATED is displayed. This completes the procedure.
NOTE: TPMS should be recalibrated each time tire inflation pressure is change\

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, a\
nd 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 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 163 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.
Tire suppliers may have additional markings, notes or warnings such as s\
tandard load, radial tubeless,
etc.

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.
l PSI: Pounds per square inch, a standard unit of air pressure.
l B-pillar: The structural member at the side of the vehicle behind the front door\
.
l Bead area of the tire: Area of the tire next to the rim.
l Sidewall of the tire: Area between the bead area and the tread.
l Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted \
on the
vehicle.
l Rim: The metal support (wheel) for a tire or a tire and tube assembly upo\
n which the tire beads are
seated.
l Maximum load rating: a figure indicating the maximum load in pounds and kilograms that can \
be
carried by the tire. This rating is established by the tire manufacturer\
.
l 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.
l Recommended tire inflation pressure: inflation pressure, established by Volvo, which is based on
the type of tires that are mounted on a vehicle at the factory. This inf\
lation pressure is affected by the
number of occupants in the vehicle, the amount of cargo, and the speed a\
t which the vehicle will be
driven for a prolonged period. This information can be 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 C\
anadian models, and in the tire
inflation table in this chapter.
l Cold tires: The tires are considered to be cold when they have the same temperatur\
e as the
surrounding (ambient) air. This temperature is normally reached after \
the vehicle has been parked for at
least 3 hours.
