uuChecking and Maintaining TiresuDOT 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 tr action 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 ca use 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.

1Traction
Warning: 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 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 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.

If a Tire Goes Flat
Changing a Flat Tire
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe place. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possible to have the full-size tire repaired or
replaced. 1.
Park the vehicle on firm, level, and non-slippery ground.
2. Put the shift lever in

3. Set the parking brake.
4. Turn on the hazard warning lights and turn the ignition switch to LOCK

1Changing a Flat Tire
Follow compact spare precautions:
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm 2
)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model.
Do not use them with another vehicle.
Do not use another type of compact spare tire or
wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire th at was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairing agent on a flat tire,
as it can damage the tire pressure sensor.

Handling the Unexpected
1. Place the jack under the jacking point
closest to the tire to be changed.
2. Turn the end bracket (as shown in the
image) clockwise until the top of the jack
contacts the jacking point.
uMake sure that the jacking point tab is
resting in the jack notch.
3. Raise the vehicle, using the jack handle bar
and the jack handle, until the tire is off the
ground.
■How to Set Up the Jack1How to Set Up the Jack
Do not use the jack with people or luggage in the
vehicle.
Use the jack provided in your vehicle.
Other jacks may not support the weight (“load”) or their shape may not match.
The following instructions must be followed to use the jack safely.
• Do not use while the engine is running.
• Use only where the ground is firm and level.
• Use only at the jacking points.
• Do not get in the vehicle while using the jack.
• Do not put anything on top of or underneath the
jack.
3WARNING
The vehicle can easily roll off the jack,
seriously injuring anyone underneath.
Follow the directions for changing a tire
exactly, and never get under the vehicle
when it is supported only by the jack.
