WA R N I N G
Do not drive the vehicle at high speeds if
the TPMS warning light turns on or flashes:
Driving the vehicle at high speeds while the
TPMS warning light is turned on or flashing
is dangerous because the brake
performance and the steering wheel
operability will be reduced. If the vehicle is
driven at high speeds or the brakes are
suddenly applied, it could lead to an
accident. Gradually apply the brakes to
lower the vehicle's speed.
Do not ignore the TPMS warning light

Continuing to drive the vehicle while
ignoring the illumination/flashing of the
TPMS warning light is dangerous because a
tire may burst which could lead to an
accident. Take appropriate measures as
soon as possible.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a tire
position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for the
tire positions may be different from the
actual tire pressures at the tire positions.
Action to be taken
Adjust the tire pressu res to the appropriate
pressures.

CAUTION
Adjust the tire pressures while the tires
are cool. Because the air pressure in the
tires
fluctuates depending on the
temperature, before adjusting the tire
pressures, let the vehicle sit for an hour or
drive it only within a 1.6 km (1 mile)
distance. If the tire pressures are adjusted
while the tires are warm, the tire
pressures may decrease below the
specified air pressure after cooling down
which could turn on the warning light. In
addition, because the air pressure in the
tires decreases when the ambient
temperature is low, if the ambient
temperature increases, an illuminated
TPMS warning light may turn off. Under
any circumstances, always adjust the tire
pressures while the tires are cool.
 After adjusting the tire pressures, the
TPMS warning light turns off. If the TPMS
warning light does not turn off, drive the
vehicle at a speed of about 25 km (16
mph) or faster for 3 minutes or longer
and make sure the warning light turns
off.
If the TPMS warning light remains on
even after adjusting the tire pressures, one
of the tires may have a puncture.
Refer to Changing a Flat Tire on page 7-7.

Tire Labeling
▼Tire Labeling
Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires.
This information
identifies and describes the fundamental
characteristics of the tire and also provides
a tire identification number for safety
standard certification and in case of a
recall.
▼ Information on Passenger Vehicle
Tires
Please refer to the sample below.

P215/65R15 95H is an example of a tire
size and load index rating. Here is an
explanation of the various components of
that tire size and load index rating. Note
that the tire size and load index rating may
be different from the example.
P
Indicates a tire that may be installed on
cars, SUVs, minivans and light trucks as
designated by the Tire and Rim
Association (T&RA).
NOTE
If your tire size does not begin with a letter
this may mean it is designated by either
ETRTO (European Tire and Rim Technical
Organization) or JATMA (Japan Tire
Manufacturing Association).
215
“215” is the nominal w idth of the tire in
millimeters. This three-digit number gives
the width in millimeters of the tire from
sidewall edge to sidewall edge. In general,
the larger the number, the wider the tire.
65
“65” is the aspect r atio. This two-digit
number indicates the tire's ratio of height
to width.
R
“R” is the tire construction symbol. R
indicates “Radial ply construction”.

U.S. DOT Tire Identification Number
(TIN)
This begins with the letters “DOT” which
indicates the tire meets all federal
standards. The next two numbers or letters
are the plant code where it was
manufactured, and the last four numbers
represent the week a nd year the tire was
manufactured. For example, the numbers
457 means the 45st week of 1997. After
2000 the numbers go to four digits. For
example, the number 2102 means the 21th
week of 2002. The other numbers are
marketing codes used at the
manufacturer's discretion. This
information is used to contact consumers
if a tire defect requires a recall.
Tire Ply Composition and Materials
Used
The number of plies indicates the number
of layers of rubber-coated fabric in the
tire. In general, the greater the number of
plies, the more weight a tire can support.
Tire manufacturers also must indicate the
tire materials, which include steel, nylon,
polyester, and other.
Maximum Load Rating
This number indicates the maximum load
in kilograms and pounds that can be
carried by the tire.
Maximum Permissible Inflation

Tread Wear, Traction and Temperature
Grades
Tr e a d w e a r : The tread wear grade is a
comparative rating based on the wear rate
of the tire when test ed 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.
Traction: The traction grades, from
highest to lowest are AA, A, B, and C.
The grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
Te m p e r a t u r e : The temperature grades are
A (the highest), 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.
Snow Tires
In some heavy snow areas, local
governments may require true snow tires,
those with very deeply cut tread. These
tires should only be us ed in pairs or placed
on all four wheels. Make sure you
purchase snow tires that are the same size
and construction type as the other tires on
your vehicle.
