Inspection and Maintenance
For your safety, perform all listed inspections and maintenance to keep your vehicle
in good condition. If you become aware of any abnormality (noise, smell, insufficient brake fluid, oil residue on the ground, etc.), have your vehicle inspected by a dealer. (Note, however, that service at a dealer is not mandatory to keep your warranties in effect.) Refer to the separate maintenance booklet for detailed maintenance and inspection information.Types of Inspection and Maintenance

Checking and Maintaining Tires
Checking Tires To safely operate your vehicle, your tires must be of the proper type and size, in good condition with adequate tread, and properly inflated.Inflation Guidelines
■
Properly inflated tires provide the best combination of handling, tread life, and
comfort. Refer to the driver’s doorjamb label or specification’s page for the specified pressure. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from overheating. Overinflated tires make your vehicle ride harshly, are more prone to road hazard, and wear unevenly. Every day before you drive, look at each of the tires. If one looks lower than the others, check the pressure with a tire gauge. At least once a month or before long trips, use a gauge to measure the pressure in all tires, including the spare. Even tires in good condition can lose 1 to 2 psi (10 to 20 kPa, 0.1 to 0.2 kgf/cm 2
) per month.
Inspection Guidelines
■
Every time you check inflation, also examine the tires and valve stems.Look for:
Bumps or bulges on the side or in the tread. Replace the tire if you find any.
•
Cuts, splits, or cracks in the side of the tire. Replace it if you see fabric or cord.Remove any foreign objects and inspect for air leaks.
•
Uneven tread wear. Have your dealer check the wheel alignment.
•
Excessive tread wear.
•
Wear Indicators P.274
Checking Tires
Measure the air pressure when tires are cold. This means the vehicle has been parked for at least three hours, or driven less than 1 mile (1.6 km). If necessary, add or release air until the speciied pressure is reached. If checked when hot, tire pressure can be as mush as 4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm 2
) higher
than if checked when cold.
Have a dealer check the tires if you feel a consist ent
vibration while driving. New tires and any that have been removed and reinstalled should be properly balanced.
WARNING
Using tires that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed. Follow all instructions in this owner’s manual regarding tire inflation and maintenance.

Glossary of Tire Terminology

■
Cold Tire Pressure – The tire air pressure when the vehicle has been parked
for at least three hours or driven less than 1 mile (1.6 km). Load Rating – Means the maximum load that a tire is rated to carry for a
given inflation pressure.Maximum Inflation Pressure – The maximum tire air pressure that the
tire can hold.Maximum Load Rating – Means the load rating for a tire at the maximum
permissible inflation pressure for that tire.Recommended Inflation Pressure – The cold tire inflation pressure
recommended by the manufacturer.Treadwear Indicators (TWI) – Means the projections within the principal
grooves designed to give a visual indication of the degrees of wear of the tread.
Tire Identiication Number (TIN)
DOT B97R FW6X 2209 DOT: This indicates that the tire meets all requirements of the U.S. Department of Transportation.B97R: Manufacturer’s identiication mark.FW6X: Tire type code.2209: Date of manufacture.

Checking and Maintaining Tires DOT Tire Quality Grading (U.S. Vehicles)
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.Uniform Tire Quality Grading

■
Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width.
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 may depart significantly from the norm due to variations
in driving habits, service practices and difference s in road characteristics and
climate.
Uniform Tire Quality Grading
For example: Treadwear 200Traction AATemperature A All passenger car tires must conform to Federal Safety Requirements in addition to these grades.

Maintenance
Checking and Maintaining Tires DOT Tire Quality Grading (U.S. Vehicles)
Traction
■
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 controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
Temperature

■
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. 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
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.
Temperature
Warning: The temperature grade for this tire is established for a tire that is properly inlated and not overloaded. Excessive speed, underinlation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.

Checking and Maintaining Tires Wear Indicators Tire Service Life
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 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 your regular inspections and inflation pressure maintenance, it is recommended that you have annual inspections performed once the tires reach five
years old. It is also recommended that all tires, including the spare, be removed from service after 10 years from the date of manufacture, regardless of their condition or state of wear. Wear Indicators shown by a mark

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.
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.
U.S. models only
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.
