Fuel information
■Fuel tank opening for unleaded gasoline
●To help prevent incorrect fueling, your Lexus has a fuel tank opening that will
only accept the special nozzle on unleaded fuel pumps.
●If premium fuel is not available, you may temporarily use unleaded gasoline with
an Octane Rating as low as 87 (Research Octane Number 91).
■If your engine knocks ...
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating
or driving up hills. This is normal and there is no need for concern.
■Gasoline quality
In very few cases, driveability problems may be caused by the brand of gasoline you
ar

e using. If driveability problems persist, try changing the brand of gasoline. If this
does not correct the problem, consult your Lexus dealer.
■Gasoline quality standards
●Automotive manufacturers in the US, Europe and Japan have developed a
specification for fuel quality called World-Wide Fuel Charter (WWFC) that is
expected to be applied worldwide.
●The WWFC consists of four categories that are based on required emission
levels. In the US, category 3 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and
customer satisfaction through better vehicle performance.
Your vehicle must use on ly unleaded gasoline. 
Select premium unleaded gasoline with an
Octane Rating of 91 (Research
Octane Number 96) or higher for optimum engine performance.
At minimum, the gasoline you use sh ould meet the specifications of
ASTM D4814 in the USA and CGSB 3.5-M93 in Canada.

6-1. Specifications
■Lexus recommends the use of gasoline containing detergent additives
●Lexus recommends the use of gasoline that contains detergent additives to
avoid build-up of engine deposits.
●All gasoline sold in the US contains detergent additives to clean and/or keep
clean intake systems.
■Lexus recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reform ulated gasoline that conta
ins oxygen-
ates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many
ar

eas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
r
eformulated gasoline. These types of gasoline provide excellent vehicle perfor -
mance, reduce vehicle emissions, and improve air quality.
■Lexus does not recommend blended gasoline
●Lexus allows the use of oxygenate blended gasoline where the oxygenate con -
tent is up to 10% ethanol or 15% MTBE.
●If you use gasohol in your Lexus, be sure that it has an octane rating no lower
than 87.
●Lexus DOES NOT recommend the use of gasoline containing methanol.
■Lexus does not recommend gasoline containing MMT
Some gasolines contain an octane enhanc
ing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl).
Lexus DOES NOT recommend the use of gasoline that contains MMT. If fuel con -
taining MMT is used, your emission control system may be adversely affected.
The Malfunction Indicator Lamp on the inst rum
ent cluster may come on. If this hap-
pens, contact your Lexus dealer for service.

NOTICE
■Notice of gasoline quality
●Do not use leaded gasoline. 
Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert -
ers causing the emission control system to malfunction.
●Do not use gasohol other than stated above. 
It will cause fuel system damage or vehicle performance problems.
●Use of unleaded fuel with an octane number or rating lower than stated above
will cause persistent heavy knocking. 
If severe, this will lead to engine damage.
■Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor hot start -
ing, vaporization, engine knoc king,
etc.), discontinue the use of that type of fuel.
■When refueling with gasohol
Take care not to spill gasohol: 
It may cause paint damage.

Tire size(P.377 )
DOT and Tire Identification Number (TIN) ( P.377 )
Location of tread wear indicators ( P.278 )
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the plies in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is a
bias-ply tire.
“TUBELESS” or “TUBE TYPE”
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 maintains the air pressure.
