Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformul ated gasoline that contains oxygenates
such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is ava ilable in many areas.
Lexus recommends the use of cleaner bu rning gasoline and appropriately blended
reformulated gasoline. These types of gaso line provide excellent vehicle performance,
reduce vehicle emissions and improve air quality. ■
Non-recommendation of the use of blended gasoline
●
If you use gasohol in your vehicle, be sure th at it has an octane rating no lower than 87.●
Lexus does not recommend the use of gasoline containing methanol.■
Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasolin e that contains MMT. If fuel containing
MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instru ment cluster may come on. If this happens,
contact your Lexus dealer for service. ■
If your engine knocks ●
Consult your Lexus dealer. ●
You may occasionally notice light knocking fo r a short time while accelerating or driv-
ing uphill. This is normal and there is no need for concern. ●
Use only gasoline containing up to 15% etha-
nol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85
(which are only some examples of fuel con-
taining more than 15% ethanol). DO NOT use gasoline
containing more than
15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

Tr e a d w e a r
The treadwear grade is a comparative rati ng 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 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.■
Tr a c t i o n A A , A , B , C
The traction grades, from highest to lowest, are AA, A, B and C, and they rep-
resent the tire’s ability to stop on we t pavement as measured under controlled
conditions on specified government te st surfaces of asphalt and concrete.A tire marked C may have poor traction performance.
Warning: The traction grade assigned to th is tire is based on braking (straight
ahead) traction tests and does not include cornering (turning) traction.■
Temperature A, B, C
The temperature grades are A (the highes t), 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.
Grade C corresponds to a level of perfor mance 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.
Warning: The temperature grades for this tire are established for a tire that is prop-
erly inflated and not overloaded.
Excessive speed, underinflation, or excessiv e loading, either separately or in com-
bination, can cause heat buildup and possible tire failure.
