■

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.

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.

■

During customization

As the engine needs to be run-

that the vehicle is parked in a 

place with adequate ventilation. In 

a closed area such as a garage, 

exhaust gases including harmful 

carbon monoxide (CO) may col-

lect and enter the vehicle. This 

may lead to death or a serious 

health hazard.
