Vehicle specifications ■
Gasoline quality
In very few cases, driveability problems may
be caused by the brand of gasoline you are
using. If driveability problems persist, try
changing the brand of gasoline. If this does
not correct the problem, consult your Lexus
dealer. ■
Recommendation of the use of gasoline
containing detergent additives●
Lexus recommends the use of gasoline
that contains detergent additives to avoid
the build-up of engine deposits.●
All gasoline sold in the U.S.A. contains
minimum detergent additives to clean
and/or keep clean intake systems, per
EPA’s lowest additive s concentration pro-
gram.
●
Lexus strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gaso-
line and a list of marketers, please go to
the official websit e www.toptiergas.com.
■
Recommendation of the use of low
emissions gasoline
Gasolines containing oxygenates such as
ethers and ethanol, as well as reformulated gasolines, are available in some cities.
These fuels are typically acceptable for use,
providing they meet other fuel require-
ments.
Lexus recommends these fuels, since the
formulations allow for reduced vehicle
emissions. ■
Non-recommendation of the use of
blended gasoline ●
Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30 (30% ethanol [ ]), E50 (50%
ethanol [ ]), E85 (85% ethanol [ ])
(which are only some examples of fuel
containing more than 15% ethanol).
●
If you use gasohol in your vehicle, be sure
that it has an octane rating no lower than
91. ●
Lexus does not recommend the use of
gasoline containing methanol. ■
Non-recommendation of the use of gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-
oline 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 hap-
pens, contact your Lexus dealer for service.
■
If your engine knocks
●
Consult your Lexus dealer.
●
You may occasionally notice light knock-
ing for a short time wh ile accelerating or Fuel information You must only use unleaded gaso-
line.
Select premium unleaded gasoline
with an octane rating of 91
(Research Octane Number 96) or
higher required for optimum
engine performance and fuel econ-
omy.
If the octane rating is less than 91,
damage to the engine may occur
and may void the vehicle warranty.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A. A

It provides the purchasers and/or pro-
spective purchasers of Lexus vehicles
with information on uniform tire quality
grading. Your Lexus dealer will help answer any
questions you may have as you read this
information. ■
DOT quality grades
All passenger vehicle tires must con-
form 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 ■
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions 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 performa nce of tires depends
upon the actual conditions of their use.
Performance may differ significantly from
the norm due to variatio ns in driving habits,
service practices and differences in road
characteristics and climate.Tire section names A
