Fuel infor mation
nFuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
nIf your engine knocks
lConsult your Toyota dealer.
lYou may occasionally notice light knocking for a short time while acceler−
ating or driving uphill. This is normal and there is no need for concern.
nGasoline quality
In very few cases, driveability problems may be caused by the brand of gas−
oline you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your Toyota dealer. Your vehicle must use only unleaded gasoline.
Unleaded gasoline with an Octane Rating of 87 (Research Octane
Number 91) or higher required for optimum engine performance.
At minimum, the gasoline you us e should meet th e specifications
of ASTM D4814 in the U.S.A.

nGasoline quality standards
lAutomotive 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.
lThe WWFC consists of four categories that are based on required emis−
sion levels. In the US, category 4 has been adopted.
lThe WWFC improves air quality by lowering emissions in vehicle fleets,
and customer satisfaction through better performance.
nToyota recommends the use of gasoline containing detergent additives
lToyota recommends the use of gasoline that contains detergent additives
to avoid build−up of engine deposits.
lAll gasoline sold in the US contains detergent additives to clean and/or
keep clean intake systems.
nToyota recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxy−
genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in
many areas.
Toyota recommends the use of cleaner burning gasoline and appropriately
blended reformulated gasoline. These types of gasoline provide excellent
vehicle performance, reduce vehicle emissions and improve air quality.
nToyota does not recommend blended gasoline
lToyota allows the use of oxygenate blended gasoline where the oxygen−
ate content is up to 10% ethanol or 15% MTBE.
lIf you use gasohol in your Toyota, be sure that it has an octane rating no
lower than 87.
lToyota DOES NOT recommend the use of gasoline containing methanol.

506 6−1. Specifications
nToyota does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy
clopentadienyl 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 cluster may come on. If
this happens, contact your Toyota dealer for service.
NOTICE
nNotice on gasoline quality
lDo not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three−way catalytic
converters causing the emission control system to malfunction.
lDo not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
lUsing 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.
nFuelrelated poor driveability
If after using a different type of fuel, poor driveability is encountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
n
When refueling with gasohole
Take care not to spill gasohol. It can damage your vehicle’s paint.

Summer tire or all season tire ( P. 396)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer tire.

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 main−
tains the air pressure.
Radial tires or bias−ply tires
A radial tire has RADIAL on the sidewall. A tire not marked RADIAL is a
bias−ply tire.

Uniform Tire Quality Grading
This information has been prepared in accordance with regulations
issued by the National Highway Tr
affic Safety Administration of the
U.S.A. Department of Transportation.
It provides the purchasers and/or
prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota dealer will help answ er any questions you may have as
you read this information.
nDOT quality grades
All passenger vehicle tires mu
st conform to Federal Safety
Requirements in addition to these grades. Quality grades can be
found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200 Traction AA Temperature A

nTreadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci−
fied government test course.
For example, a tire graded 150 would wear one and a half (1 − 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may depart significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
nTraction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ab ility to stop on wet pavement as
measured under controlled cond itions on specified government
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 (turn−
ing) traction.
nTemperature A, B, C
The temperature grades are A (the highest), B, and C, represent−
ing the tire’s resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci−
fied 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 sudden tire failure.
The grade C corresponds to a level of performance which all passen−
ger car tires must meet under the Federal Motor Vehicle Safety Stan−
dard No. 109.
Grades B and A represent higher levels of performance on the labo−
ratory test wheel than the minimum required by law.
