nToyota does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy
clopentadienyl Manganese Tricarbonyl).
Toyota DOES NOT recommend the use of gasoline that contains MMT. If
fuel containing MMT is used, your emission control system may be
adversely affected.
The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your Toyota dealer for service.
NOTICE
nNotice on gasoline quality
lDo not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three−way catalytic
converters causing the emission control system to malfunction.
lDo not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
lUsing unleaded gasoline with an octane number or rating lower than that
stated here will cause persistent heavy knocking.
At worst, this will lead to engine damage.
nFuel related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
n
When refueling with gasohole
Take care not to spill gasohol. It can damage your vehicle’s paint.

A tubeless tire does not have a tube and air is directly filled in the
tire. A tube type tire has a tube inside the tire and the tube main−

Radial tires or bias−ply tires
A radial tire has RADIAL on the sidewall. A tire not marked RADIAL is a
bias−ply tire.

Uniform Tire Quality Grading
This information has been prepared in accordance with regulations
issued by the National Highway Tr
affic Safety Administration of the
U.S.A. Department of Transportation.
It provides the purchasers and/or
prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota dealer will help answ er any questions you may have as
you read this information.
nDOT quality grades
All passenger vehicle tires mu
st conform to Federal Safety
Requirements in addition to these grades. Quality grades can be
found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200 Traction AA Temperature A

nTreadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci−
fied government test course.
For example, a tire graded 150 would wear one and a 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 differences in
road characteristics and climate.
nTraction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ab ility to stop on wet pavement as
measured under controlled cond itions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn−
ing) traction.
nTemperature A, B, C
The temperature grades are A (the highest), B, and C, represent−
ing the tire’s resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci−
fied 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 passen−
ger car tires must meet under the Federal Motor Vehicle Safety Stan−
dard No. 109.
Grades B and A represent higher levels of performance on the labo−
ratory test wheel than the minimum required by law.
Page 505 of 531

512 6−1. Specifications
Warning: The temperature grades for this tire are established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa−
rately or in combination, can cause heat buildup and possible tire fail−
ure.
