Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps.
■If premium gasoline is not available
If this premium fuel is not available, you may use unleaded gasoline with an Octane
Rating of 87 or so (Research Octane Number 91).
The use of such gasoline may cause the engine to knock or drastically reduce out-
put to protect itself while driving with a heavy load. To avoid this, refill the tank with
premium unleaded gasoline as soon as possible.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating
or driving uphill. 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
are using. If driveability problems persist, try changing the brand of gasoline. If this
does not correct the problem, consult your Lexus dealer.
Your vehicle must use only unleaded gasoline.
Premium unleaded gasoline with an Octane Rating of 91 (Research
Octane Number 96) or higher required for optimum engine performance.
At minimum, the gasoline you us e should meet the specifications of
ASTM D4814 in the U.S.A. an d CGSB3.5-M93 in Canada.

Vehicle specifications
■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 4 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and
customer satisfaction through better performance.
■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 de tergent 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 contains oxygen-
ates such as ethanol or MTBE (Methyl Te rtiary Butyl Ether) is available in many
areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
reformulated 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 gasoline contains octane enhancin g additive called MMT (Methylcy clopen-
tadienyl 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 rument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.

NOTICE
■Notice on 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 that stated here.
Other gasohol may cause fuel system damage or vehicle performance problems.
●Using unleaded gasoline with an octane number or rating lower than that stated
here will cause persistent heavy knocking.
At worst, 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 gasohole
Take care not to spill gasohol. It can damage your vehicle's paint.

DOT and Tire Identification Number (TIN) ( P. 382)
Location of tread wear indicators ( P. 384)
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the plies in a tire.
Summer tire or all season tire ( P. 2 9 7 )
An all season tire has “M+S” on the si dewall. A tire not marked “M+S” is a
summer 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 an d air is directly filled in the tire. A
tube type tire has a tube inside the ti re and the tube maintains the air pres-
sure.
Load limit at maximum cold tire inflation pressure ( P. 386)
Maximum cold tire inflation pressure ( P. 386)
This means the pressure to which a tire may be inflated.
