TPMS (Tire Pressure Monitoring System)
If any tire has low pressure, "LOW TIRE
PRESSURE" is displayed on the multi-
information display. Check the pressure of
each tire by pressing the
SEL /RESET
button."CHECK TIRE PRESSURE" is displayed when a
tire has significantly low pressure. The specific
tire is displayed on the screen.
TPMS (Tire Pressure Monitoring System)
Tire pressure checked and inflated in:
Warm weather can become under-inflated in tcolder weather.
Cool weather can become over-inflated in warmer tweather.
The low tire pressure/ TPMS indicator will not come
on as a result of over inflation.

When Driving
Tire Pressure Monitoring System (TPMS) - Required Federal Explanation
U.S. models Tire Pressure Monitoring System (TPMS) - Required
Federal ExplanationEach tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop
and check your tires as soon as possible, and inflate them to the proper
pressure.
Driving on a significantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain correct tire pressure, even
if under-inflation has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.

Checking and Maintaining Tires
Maintenance
Checking TiresTo 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 t
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. t
Uneven tread wear. Have your dealer check the wheel alignment. t
Excessive tread wear. t

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. 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 specified
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 consistent
vibration while driving. New tires and any that have
been removed and reinstalled should be properly
balanced.

Tire Identification Number (TIN)
The tire identification number (TIN) is a group of numbers and letters that
look like the example in the side column. TIN is located on the sidewall of
the tire.
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 Identification 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 identification mark.
FW6X: Tire type code.
2209: Date of manufacture.

264Maintenance
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.
Checking TiresHigh 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 tire pressures as shown below
to avoid excessive heat build up and sudden tire
failure. 6-cylinder models Tire Size P235/45R18 94V
Pressure 35 psi (240 kPa, 2.4 kgf/cm
2)
4-cylinder models Tire Size P225/50R17 93V
Pressure 35 psi (240 kPa, 2.4 kgf/cm
2)
If you do not, excessive heat can build up and cause
sudden tire failure.
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.
