■
Engine oil selection
“Toyota Genuine Motor Oil” is used in
your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil”
or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-6A multigrade
engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good starting
in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20 at
the next oil change.
Outside temperature
Oil viscosity (0W-20 is explained here
as an example):
• The 0W in 0W-20 indicates the
characteristic of the oil which allows
cold startability. Oils with a lower
value before the W allow for easier
starting of the engine in cold
weather.
• The 20 in 0W-20 indicates the vis-
cosity characteristic of the oil when
the oil is at high temperature. An oil
with a higher viscosity (one with a
higher value) may be better suited if
the vehicle is operated at high
speeds, or under extreme load con-
ditions.
How to read oil container label:
The International Lubricant Specifica-
tion Advisory Committee (ILSAC)
Certification Mark is added to some oil
containers to help you select the oil you
should use.

■
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 additives 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 website 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
87.
●
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 while accelerating or
driving uphill. This is normal and there is
no need for concern.
Fuel information
You must only use unleaded gaso-
line.
Select octane rating 87 (Research
Octane Number 91) or higher. Use
of unleaded gasoline with an
octane rating lower than 87 may
result in engine knocking. Per-
sistent knocking can lead to engine
damage.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A.

NOTICE
■
Notice on fuel quality
●
Do not use improper fuels. If improper
fuels are used, the engine will be dam-
aged.
●
Do not use leaded gasoline.
Leaded gasoline can cause damage to
your vehicle’s three-way catalytic con-
verters causing the emission control
system to malfunction.
●
Do not use gasohol other than the type
previously stated.
Other gasohol may cause fuel system
damage or vehicle performance prob-
lems.
●
Using unleaded gasoline with an
octane number or rating lower than
the level previously stated will cause
persistent heavy knocking.
At worst, this will lead to engine dam-
age.
■
When refueling with gasohol
Take care not to spill gasohol. It can dam-
age your vehicle’s paint.
■
Fuel-related poor driveability
If poor driveability (poor hot starting,
vaporization, engine knocking, etc.) is
encountered after using a different type
of fuel, discontinue the use of that type of
fuel.

■
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 performance of tires depends
upon the actual conditions of their use.
Performance may differ significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
■
Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment 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 (turning) traction.
■
Temperature A, B, C
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 condi-
tions 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 of a tire
assume that it is properly inflated and not
overloaded.
Excessive speed, underinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
