DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width.
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 may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.

All passenger car tires must conform
to Federal Safety Requirements in addition to these grades.

Maintenance
The traction grades, from highest to lowest, are AA, A, B, and C. Those grades repres ent 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.
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 la boratory 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 level of performance which
all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.
■Traction
■Temperature
1Traction
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests, and does not incl ude acceleration,
cornering, hydroplaning, or peak
traction characteristics.
1Temperature
Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat build up and possible
tire failure.

uuChecking and Maintaining TiresuWear Indicators
Maintenance
Wear IndicatorsThe groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower than
elsewhere on the tire. If the tread has worn so
that the indicator is exposed, replace the tire.
Worn out tires have poor traction on wet
roads.
Tire Service Life
The life of your tires is dependent on man y factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires, including the spare, should be removed from service after 10
years from the date of manufacture, regardless of their condition or state of wear.
1Checking Tires
High speed driving
We recommend that you do not drive faster than the
posted speed limits and conditions allow. If you drive
at sustained high speeds (over 118 mph or 190
km/h), adjust the cold tire pressures as shown below
to avoid excessive heat build up and sudden tire
failure.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause the ABS and VSA®
(vehicle stability assist)
system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
Make sure that the wheel’s specifications match those of the original wheels.
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.

3WARNING
Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or
killed.
Always use the size and type of tires
recommended in this owner’s manual.

Tire Rotation
Rotating tires according to the maintenance messages on the information display*

helps to distribute wear more evenly and increase tire life.
■ Tires without rotation marks
Rotate the tires as shown here.
■ Tires with rotation marks
Rotate the tires as shown here.
1Tire Rotation
Tires with directional tread patterns should only be
rotated front to back (not from one side to the other).
Directional tires should be mounted with the rotation
indication mark facing forward, as shown below.

Maintenance
Winter Tires
If driving on snowy or frozen roads, mount all season marked ”M+S” tires, snow
tires, or tire chains; reduce speed; and maintain sufficient distance between vehicles when driving.
Be particularly careful when operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season tires when necessary or according to the law.
When mounting, refer to the following points.
For winter tires: • Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:• Install them on the front tires only.
• Because your vehicle has limited tire clearance, we strongly recommend using the
chains listed below:
• Follow the chain manufacturer's instruc tion when installing. Mount them as
tightly as you can.
• Check that the chains do not touch the brake lines or suspension.
• Drive slowly.

NOTICE
Traction devices that are the wrong size or improperly
installed can damage your vehicle's brake lines,
suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
When tire chains are mounted, follow the chain
manufacturer's instructions regarding vehicle
operational limits.
If your vehicle is equipped with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact a dealer.
3WARNING
Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instruction s in this owner's
manual regarding the selection and use of
tire chains.

Dust and Pollen Filter *
The heating and cooling system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance Minder TM
messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.

If the airflow from the heating and cooling system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

1Interior Care
Do not spill liquids inside the vehicle.
Electrical devices and systems may malfunction if
liquids are splashed on them.
Do not use silicone based sprays on electrical devices
such as audio devices and switches.
Doing so may cause the items to malfunction or a fire
inside the vehicle.
If a silicone based spray is inadvertently used on
electrical devices, consult a dealer.
Depending on their composition, chemicals and
liquid aromatics may cause discoloration, wrinkles,
and cracking to resin-based parts and textiles.
Do not use alkali solvents or organic solvents such as
benzene or gasoline.
After using chemicals, make sure to gently wipe them
off using a dry cloth.
Do not place used cloths on top of resin based parts
or textiles for long periods of time without washing.
