Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only accommo-
dates the special nozzle on unleaded fuel pumps.
■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.
■Gasoline quality standards
●Automotive manufacturers in the U.S.A., Eu rope and Japan have developed a specifi-
cation for fuel quality called the World-Wi de Fuel Charter (WWFC), which is expected
to be applied worldwide.
●The WWFC consists of four cat egories that are based on required emission levels. In
the U.S., category 4 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets, and improves
customer satisfaction through better performance.
You must only use unleaded gasoline in your vehicle.
Select premium unleaded gasoline with an octane rating of 91 (Research
Octane Number 96) or higher required for optimum engine performance. If
91 octane cannot be obtained, you may use unleaded gasoline with an octane
rating as low as 87 (Research Octane Number 91). Use of unleaded gasoline
with an octane rating lower than 91 ma y result in engine knocking. Persistent
knocking can lead to engine damage and should be corrected by refueling
with higher octane unleaded gasoline.
At minimum, the gasoline you use should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB3.5-M93 in Canada.

Vehicle specifications
■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 program.
●Lexus strongly recommends the use of Top Ti er Detergent Gasoline. For more informa-
tion on Top Tier Detergent Gasoline and a list of marketers, please go to the official
website www.toptiergas.com.
■Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformul ated gasoline that contains oxygenates
such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas.
Lexus recommends the use of cleaner bu rning gasoline and appropriately blended
reformulated gasoline. These types of gaso line provide excellent vehicle performance,
reduce vehicle emissions and improve air quality.
■Non-recommendation of the use of blended gasoline
●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.
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcy clopenta-
dienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasolin e that contains MMT. If fuel containing
MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instru ment cluster may come on. If this happens,
contact your Lexus dealer for service.
●Use only gasoline containing a maximum of
10% ethanol.
DO NOT use any flex-fuel or gasoline that
could contain more than 10% ethanol, includ-
ing from any pump labeled E15, E30, E50,
E85 (which are only some examples of fuel
containing more than 10% ethanol).DO NOT use gasoline con-
taining more than 10% eth-
anol.
(15% ethanol)
(50% ethanol)
(85% ethanol)

■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking fo
r a short time while accelerating or driv-
ing 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 damaged.
●Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters
causing the emission control system to malfunction.
●Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system da mage or vehicle performance problems.
●Using unleaded gasoline with an octane number or rating lower than the level previ-
ously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■Fuel-related poor driveability
If poor driveability is encounte red after using a different type of fuel (poor hot starting,
vaporization, engine knocking, etc.), disc ontinue the use of that type of fuel.
■When refueling with gasohole
Take care not to spill gasohol. It can damage your vehicle’s paint.

( P. 5 6 9 )
DOT and Tire Identification Number (TIN) ( P. 5 6 8 )
Location of treadwear indicators (P. 464)
Tire ply composition and materials
Plies are layers of rubber-coated parallel co rds. 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 put into the tire. A tube type tire
has a tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure ( P. 5 7 3 )
Maximum cold tire inflation pressure ( P. 5 7 3 )
This means the pressure to which a tire may be inflated.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires ( P. 4 6 7 )
An all season tire has “M+S” on the sidewall. A tire not marked “M+S” is a summer
tire.
