Vehicle specifications
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.
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 may cause
persistent he avy knocking.
At worst, this may lead to engine dam-
age and will void the vehicle warranty.
■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.
■When refueling with gasohol
Take care not to spill gasohol. It can
damage your vehicle’s paint.

4148-1. Specifications
■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 sudd
en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral 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, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
