When the CMBS
TM is off:
•The beeper sounds.
•The CMBS
TM indicator in the instrument
panel comes on.
•A message on the MID reminds you that the
system is off.
The CMBS

•You drive off-road or on a mountain road for an
extended period.•You drive with the parking brake applied.•You drive in bad weather (rain, fog, snow, etc.)•The radar sensor cover is blocked by dirt, mud, dry
leaves, wet snow, etc.•An abnormal tire condition is detected (wrong tire
size, flat tire, etc.)
Once the conditions that caused the CMBS

Checking and Maintaining TiresChecking 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 hazards,
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 and 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 a dealer check the wheel alignment.
•Excessive tread wear.2Wear Indicators P. 422
•Cracks or other damage around valve stem.
1Checking 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 much 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.

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.

uuChecking and Maintaining TiresuTire Labeling
Maintenance
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.
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)■Glossary of Tire Terminology
1Tire Identification Number (TIN)DOT B97R FW6X 2209
DOT: This indicates that the tire meets all
requirements of the U.S. Department of
Transportation.

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 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 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■Temperature
1TractionWarning: 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 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.

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, 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).
1Changing a Flat Tire
*
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 that 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.
