Tire Pressure Monitoring System (TPMS) -U.S models only
The tire pressure monitoring system uses sensors mounted in the tire valves 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 vehicle.
NOTE
USA - FCC ID: KR5S122780002
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 device must accept any interference received, including interference
that may cause undesired operation.
When low inflation pressure is detected, TPMS will light up the tire pressure 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 pressure loss.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE PRESS
ProCarManuals.com

SYST SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle 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 inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure 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. Driving 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 and
stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation 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 approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent 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 occur for a variety of reasons, including the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.

NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the tables beginning on page 250
, or consult your Volvo retailer.
The tire pressure warning light will not identify which tire is under-inflated. Be sure to check all four tires.
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.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the tables beginning on page 250
).
3. In certain cases, it may be necessary to 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
ProCarManuals.com

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 installed TPMS wheels/tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will be
displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear. If the message is still
displayed, drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster to erase the message.
Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend
moving sensors back and forth between sets of wheels.
NOTE
If you change to tires with a different recommended inflation pressure, the TPMS system must be recalibrated to
these tires. This must be done by a trained and qualified Volvo service technician.
If a tire is changed, or if the TPMS sensor is moved to another wheel, the sensor's seal, nut, and valve core should
be replaced.
When installing TPMS sensors, the vehicle must be parked for at least 15 minutes with the ignition off. if the
vehicle is driven within 15 minutes, a TPMS error message will be displayed.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging the valve.

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):
ProCarManuals.com

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 258
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.

Inflation pressure: A measure of the amount of air in a tire.
Standard load: A class of P-metric or Metric tires designed to carry a maximum load at 35 psi [37 psi (2.5 bar) for
Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying capability.
Extra load : A class of P-metric or Metric tires designed to carry a heavier maximum load at 41 psi [43 psi (2.9 bar)
for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tire's load carrying
capability.
kPa : Kilopascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unit of air pressure.
B-pillar: The structural member at the side of the vehicle behind the front door.
Bead area of the tire : Area of the tire next to the rim.
Sidewall of the tire: Area between the bead area and the tread.
Tread area of the tire : Area of the perimeter of the tire that contacts the road when mounted on the vehicle.
Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are seated.
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.
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.
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 inflation pressure is affected by the number of occupants in the
vehicle, the amount of cargo, and the speed at 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 Canadian models, and in the tire inflation table in this chapter.
Cold tires : 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 for at least 3 hours.

Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for determining your vehicle's weight
ratings, with or without a trailer, from the vehicle's Federal/Canadian Motor Vehicle Safety Standards
(FMVSS/CMVSS) label, and the vehicle's tire information placard:
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 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" on page 213
.
Permissible axle weight
The 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

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
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.
