DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle m eet 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.
Quality grades can be found where applicable on th e tire sidewall
between tread shoulder and maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested un der 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 co nditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practi ces and differences in road
characteristics and climate.
■Uniform Tire Quality Grading
■Treadwear
1 Uniform Tire Quality Grading
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.

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 asph alt 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 h eat 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 temp erature 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
1 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.
1Temperature
Warning: The temperature grade for
this tire is establishe d 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.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure ra ting (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause the ABS, vehicle stability assist (VSA ®), hill
start assist, and the All-Wheel Drive (AWD) with intelligent control 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.
If you replace a wheel, only use TPMS sp ecified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

3WARNING
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.

Maintenance
Climate Control System Maintenance
Dust and Pollen Filter
The climate control system is equipped wi th a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Dust and Pollen Filter
If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

uuIndicator, Coming On/Blinking uIf the Malfunction Indicator Lamp Comes On or Blinks
Handling the Unexpected
If the Malfunction Indica tor Lamp Comes On or
Blinks
■Reasons for the indicator la mp to come on or blink
• Comes on when there is a problem with the engine emissions control
system, or the fuel fill cap is missing, or loose.
• Blinks when engine misfiring is detected.
■What to do when the indicator lamp comes on
Avoid high speeds and immediately get your vehicle inspected at a
dealer.
■What to do when the indicator lamp blinks
Park the vehicle in a safe place with no flammable items and wait at least
ten minutes or more with the engine stopped until it cools.
■The message appears on when:
An evaporative system leak is detected. This may be caused by the fuel fill cap being
loose or not being installed.
■What to do when the message appears:
1. Stop the engine.
2. Check that the fuel fill cap is fully installed.
u If not, loosen the cap, and then reti ghten it until it clicks at least once.
3. Drive for several days of normal driving.
u The message should go off.
■When the malfunction indicator lamp comes on
Malfunction indicator lamp comes on if th e system continues to detect a leak of
gasoline vapor. If this happens, check the fuel fill cap using the procedures described
above.
■Tighten Fuel Cap Message
1 If the Malfunction Indicato r Lamp Comes On or Blinks
NOTICE
If you drive with the malf unction indicator lamp on,
the emissions control system and the engine could be
damaged.
If the malfunction indicator lamp blinks again when
restarting the engine, drive to the nearest dealer at
31 mph (50 km/h) or less. Have your vehicle
inspected.

uuEmissions Testing uTesting of Readiness Codes
Information
7. Select a nearby, lightly traveled major hi ghway where you can maintain a speed
of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway in
(D. Do not use cruise control. When tra ffic allows, drive for 90 seconds without
moving the accelerator pedal. (Vehicle spee d may vary slightly; this is okay.) If you
cannot do this for a continuous 90 seconds because of traffic conditions, drive for
at least 30 seconds, then repeat it two mo re times (for a total of 90 seconds).
8. Drive in city or suburban traffic for at le ast 10 minutes. When traffic conditions
allow, let the vehicle coast for several se conds without using the accelerator pedal
or the brake pedal.
9. Park the vehicle and leave the engine off for 30 minutes.
