■

Gasoline quality

In very few cases, driveability prob-

lems 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

Toyota dealer.

■

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. con-

tains minimum detergent additives

to clean and/or keep clean intake

systems, per EPA’s lowest addi-

tives concentration program.

●

Toyota strongly recommends the

use of Top Tier Detergent Gaso-

line. For more information on Top

Tier Detergent Gasoline and a list

of marketers, please go to the offi-

cial 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 avail-

able in some cities. These fuels are

typically acceptable for use, provid-

ing they meet other fuel require-

ments.
Toyota recommends these fuels,

since the formulations allow for

reduced vehicle emissions.

■

Non-recommendation of the

use of blended gasoline

●

Use only gasoline containing up to

15% ethanol.

DO NOT use any flex-fuel or gas-

oline that could contain more than

15% ethanol, including from any

pump labeled E30 (30% ethanol
[

]), E50 (50% ethanol [

]), E85

(85% ethanol [

]) (which are only

some examples of fuel containing

more than 15% ethanol).

●

If you use gasohol in your vehicle,

be sure that it has an octane rat-

ing no lower than 87.

●

Toyota does not recommend the

use of gasoline containing metha-

nol.

■

Non-recommendation of the

use of gasoline containing MMT

Some gasoline contains an octane

enhancing additive called MMT

(Methylcyclopentadienyl Manga-

nese Tricarbonyl).
Toyota does not recommend the use

of gasoline that contains MMT. If

fuel containing MMT is used, your

emission control system may be

Fuel information

You must only use unleaded
gasoline.
Select octane rating of 87
(Research Octane Number
91) or higher. Use of
unleaded gasoline with an
octane rating lower than 87
may result in engine knock-
ing. Persistent knocking
can lead to engine damage.

At minimum, the gasoline you
use should meet the specifica-
tions of ASTM D4814 in the
U.S.A.

536

9-1. Specifications

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

accelerating 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 per-

formance 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 start-

ing, vaporization, engine knock-

ing, etc.) is encountered after

using a different type of fuel, dis-

continue the use of that type of

fuel.

■

When refueling with gasohol

Take care not to spill gasohol. It

can damage your vehicle’s paint.

This information has been pre-

Highway Traffic Safety Adminis-
tration of the U.S. Department of
Transportation.
It provides the purchasers
and/or prospective purchasers
of Toyota vehicles with informa-
tion on uniform tire quality grad-
ing.

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
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 Trac-
tion AA Temperature A

■

Treadwear

The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified 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. 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 high-
est 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 govern-
ment 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 corner-
ing (turning) traction.

■

Temperature A, B, C

The temperature grades are A

(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory 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 Fed-
eral Motor Vehicle Safety Standard
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 fail-
ure.
