inflation pressure VOLVO XC70 2007 User Guide

2007 Volvo XC70
Tire Pressure Monitoring System (TPMS) - option on certain U.S. models\

only
- Use a tire pressure gauge to check the inflation pressure of all four \
tires.
- Re-inflate the tire(s) to the correct pressure (consult the tire pr\
essure placard or the tables on
pages 160
and 161.
- 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.

self supporting run flat tires.
Tires of this type have specially reinforced sidewalls that make it poss\
ible to continue driving in the
event of a drop in inflation pressure. Tires of this type are mounted on\
special rims.
NOTE: Self supporting run flat tires are only available in conjunction with T\
PMS.
If a self supporting run flat tire should lose inflation pressure, the y\
ellow TPMS warning symbol (
) in
the instrument panel lights up to alert the driver, and a message will b\
e shown in the text window in the
instrument panel.
If this occurs, reduce vehicle speed to a maximum of 50 mph (80 km/h).\
The vehicle can be driven
approximately 50 miles (80 km), or somewhat farther if the vehicle is \
not heavily loaded. The tire should
be replaced as soon as possible.
Hard braking and sudden steering maneuvers should be avoided.
In certain cases, it may be difficult to see which self supporting run f\
lat tire is defective.
To determine which tire is damaged, check the inflation pressure of all \
four tires.
WARNING!
l Only specially trained persons should mount self supporting run flat tir\
es.
l If self supporting run flat tires are mounted, the vehicle must be equip\
ped with a Tire Pressure
Monitoring System.
l After a low pressure warning has been displayed, do not exceed 50 mph (\
80 km/ h).
l Avoid severe cornering and hard braking, and minimize the distance trave\
led before replacing the
self supporting run flat tire.
l Self supporting run flat tires cannot be repaired. They must be replaced\
if damaged or punctured.

Federal law mandates that tire manufacturers place standardized informat\
ion 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 desi\
gnation):
1. 215: the width of the tire (in millimeters) from sidewall edge to s\
idewall 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, 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 169 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
Tire suppliers may have additional markings, notes or warnings such as s\
tandard load, radial tubeless,
etc.
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.

Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle des\
ign performance.
Before loading your vehicle, familiarize yourself with the following ter\
ms for determining your vehicle's
weight ratings, with or without a trailer, from the vehicle's Federal/ C\
anadian Motor Vehicle Safety
Standards (FMVSS/CMVSS) label, and the vehicle's tire information plac\
ard:
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 equipm\
ent. When towing, trailer hitch
tongue load is also part of cargo weight.
NOTE: For trailer towing information, please refer to the section "Towing a tr\
ailer" on
page 145.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (fron\
t or rear). These numbers are
shown on the Federal/Canadian Motor Vehicle Safety Standards (FMVSS/ CM\
VSS) label. The total
load on each axle must never exceed its maximum permissible weight.
