uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire’s ability to stop on wet pavement
as measured under controlle d 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 indo or 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 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.■

1 TractionWarning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.1TemperatureWarning: 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 buildup and possible
tire failure.

uuChecking and Maintaining Tires uWear Indicators
Maintenance
Wear Indicators
The 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 LifeThe life of your tires is dependent on many 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.
1 Checking 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 (models with P245/45R18
96V tires: over 112 mph or 180 km/h, models with
245/40R19 98W tires: 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.Tire Size
P245/45R18 96V
Pressure Front: 35 psi (240 kPa, 2.4 kgf/cm

Rear: 33 psi (230 kPa, 2.3 kgf/cm2)

uuChecking and Maintaining Tires uTire and Wheel Replacement
Maintenance
Tire and Wheel ReplacementReplace 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 vehicle stability assist (VSA ®)
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.

WARNING
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.

uuChecking and Maintaining Tires uTire Rotation
Maintenance
Tire RotationRotating tires according to the maintenance messages on the multi-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 marksRotate 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.

uuChecking and Maintaining Tires uWinter Tires
Maintenance
Winter TiresIf 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 instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not touch the brake lines or suspension.
• Drive slowly.Cable-type: SCC Radial Chain SC1040
1Winter TiresNOTICETraction 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.
3
WARNING
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 instruc tions in this owner’s
manual regarding the selection and use of
tire chains.

Handling the Unexpected
If a Tire Goes FlatTemporarily Repairing a Flat TireIf the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can
use the temporary tire repair kit so that you can drive to the nearest service station
for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1.Park the vehicle on a firm, level, and non-slippery surface and apply the parking
brake.
2. Move the shift lever to
(P
.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).

Getting Ready to Temporarily Repair the Flat Tire
1Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact a dealer or a roadside assistant to
have the vehicle towed.•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4mm).•The tire side wall is damaged or the puncture is
outside the contact area.•Damage has been caused by driving with the tire
extremely under inflated.•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.NOTICEDo not use a puncture-repairing agent other than the
one provided in the ki t that came with your vehicle. If
a different agent is us ed, you may permanently
damage the tire pressure sensor.

Injecting Sealant and Air
1Injecting Sealant and Air
In cold temperatures, the sealant may not flow easily.
In this situation, warm it up for five minutes before
using.
The sealant can permanently stain clothing and other
materials. Be careful during handling and wipe away
any spills immediately.

WARNING
Tire sealant contains substances that are
harmful and can be fatal if swallowed.
If accidentally swallowed, do not induce
vomiting. Drink plenty of water and get
medical attention immediately.
For skin or eye contact, flush with cool
water and get medical attention if
necessary.
