Fuel information
■Gasoline quality
In very few cases, driveability problems may be caused by the b rand of gaso-
line you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your To yota dealer.
■ Gasoline quality standards
●Automotive manufacturers in the U.S.A., the Europe and Japan have devel-
oped a specification for fuel quality called World-Wide Fuel Ch arter
(WWFC), which is expected to be applied worldwide.
● The WWFC improves air quality by lowering emissions in vehicle fleets, and
improves customer satisfaction through better performance.
■ Recommendation of the use of gaso line containing detergent additives
● Toyota recommends the use of gasoline that contains detergent a dditives to
avoid build-up of engine deposits.
● All gasoline sold in the U.S.A. contains minimum detergent addi tives to
clean and/or keep clean intake systems, EPA’s lowest additives concentra-
tion program.
● Toyota strongly recommends the use of Top Tier Detergent Gasoli ne. For
more information on Top Tier Detergent Gasoline and a list of marketers,
please go to the official website www.toptiergas.com.
You must only use unleaded gasoline in your vehicle.
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. Persistent knocking can lead to
engine damage.
At minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A..

Vehicle specifications
■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 fue ls are typically
acceptable for use, providing they meet other fuel requirements .
Toyota recommends these fuels, since the formulations allow for reduced
vehicle emissions.
■ Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure that it has an octa ne rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methan ol.
■ Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument panel may come on. If this
happens, contact your Toyota dealer for service.
■ If your engine knocks
●Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time whi le accelerat-
ing or driving uphill. This is normal and there is no need for concern.
●
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, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).
DO NOT use gaso-
line containing more
than 15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

NOTICE
■Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engi ne will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s catalytic co nverters
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 performan ce
problems.
● 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 damage.
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine k nocking, 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.

Tire size( P. 5 3 2 )
DOT and Tire Identification Number (TIN) ( P. 5 3 1 )
Uniform tire quality grading
For details, see “Uniform Tire Q uality Grading” that follows.
Location of treadwear indicators ( P. 4 2 0 )
Run-flat tire (RFT) or standard tire ( P. 4 9 9 )
This vehicle can be equipped with either run-flat tires (RFT) o r stan-
dard tires. A “RFT” or “DSST” mark is molded on the sidewall of the
run-flat tire.
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the p lies 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 insi de the tire and the tube mainta ins the air
pressure.
Load limit at maximum cold tire inflation pressure ( P. 4 2 3 )
Maximum cold tire in flation pressure (P. 5 2 2 )
This means the press ure to which a tire may be inflated.
Summer tires or all season tires ( P. 4 2 4 )
An all season tire has “M+S” on the sidewall. A tire not marked “M+S”
is a summer tire.
“TEMPORARY USE ONLY” ( P. 4 9 6 )
A compact spare tire is identified by the phrase “TEMPORARY USE
ONLY” molded on its sidewall. This tire is designed for tempora ry
emergency use only.
