Gasoline quality

In very few cases, driveability problems may be caused by the brand 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 Toyota dealer.

Fuel information

You must only use unleaded gasoline.
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..

■

Recommendation of the use of gasoline containing detergent additives

●

Toyota 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 concen-
tration program.

●

Toyota strongly recommends the use of Top Tier Detergent Gasoline. For
more information on Top Tier Detergent Gasoline and a list of marketers,
please go to the official website www.toptiergas.com.

■

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 fuels 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 octane rating no
lower than 87.

●

Toyota does not recommend the use of gasoline containing methanol.

●

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 gasoline
containing more than
15% ethanol.

(50% ethanol)

8-1. Specifications

■

Non-recommendation of the use of gasoline containing MMT

Some gasoline contains an 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.

■

If your engine knocks

●

Consult your Toyota dealer.

●

You may occasionally notice light knocking for a short time while accelerat-
ing or driving 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 damage or vehicle performance
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 knocking, 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.

A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL”
is a bias-ply tire.

This  information  has  been  prepared  in  accordance  with  regulations
issued  by  the  National  Highway  Traffic  Safety Administration  of  the
U.S. 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 answer any questions you may have as
you read this information.

■

DOT quality grades

All passenger vehicle tires must conform to Federal Safety Require-
ments 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

■

Treadwear

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 condi-
tions of their use. Performance may differ significantly from the norm
due to variations in driving habits, service practices and differences
in road characteristics and climate.

■

Traction AA, A, B, C

The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions 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.

Uniform Tire Quality Grading

542

8-1. Specifications

■

Temperature A, B, C

The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate heat when tested under controlled conditions on a specified
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.
Grade C corresponds to a level of performance which all passenger
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.
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately  or  in  combination,  can  cause  heat  buildup  and  possible  tire
failure.
