and check the oil level on the dipstick.

  Engine oil selection

“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use

Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat-

isfy the following grade and viscosity.

Oil grade: ILSAC GF-5 multigrade engine oil

Recommended viscosity: SAE 0W-20

SAE 0W-20 is the best choice

for good fuel economy and

good starting in cold weather.

If SAE 0W-20 is not available,

SAE 5W-20 oil may be used.

However, it must be replaced

with SAE 0W-20 at the next oil

Outside temperature

change.

595

Oil viscosity (0W-20 is explained here as an example):

The 0W in 0W-20 indicates the characteristic of the oil which allows cold

startability. Oils with a lower value before the W allow for easier starting

of the engine in cold weather.

The 20 in 0W-20 indicates the viscosity characteristic of the oil when the

oil is at high temperature. An oil with a higher viscosity (one with a

higher value) may be better suited if the vehicle is operated at high

speeds, or under extreme load conditions.

How to read oil container label:

The International Lubricant

Specification Advisory Commit-

tee (ILSAC) Certification Mark

is added to some oil containers

to help you select the oil you

should use.

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.

You must only use unleaded gasoline, E85, or a blend of the two

fuels.

Unleaded gasoline (Octane rating 87 [Research Octane Number

91] or higher), E85, or a blend of two fuels is required for opti-

mum engine performance.

The use of unleaded gasoline with an octane rating lower than

87 may result in engine knocking. Persistent knocking can lead

to engine damage.

The use of fuel with an ethanol concentration in excess of 85%

will have a negative impact on driving performance and can

cause damage to the fuel system components.

At minimum, the gasoline you use should meet the specifications of

ASTM D4814 in the U.S.A.

At minimum, the E85 you use should meet the specifications of

ASTM D5798 in the U.S.A.

 Identifying flex-fuel vehicles

Flex-fuel vehicles can be identified by the

fuel tank cap, which is marked “FLEX-

FUEL E85/GASOLINE”.

603

 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.

 Gasoline quality standards

Automotive manufacturers in the U.S.A., Europe and Japan have developed

a specification for fuel quality called the World-Wide Fuel Charter (WWFC),

which is expected to be applied worldwide.

The WWFC consists of four categories that are based on required emission

levels. In the U.S., category 4 has been adopted.

The WWFC improves air quality by lowering emissions in vehicle fleets, and

improves customer satisfaction through better performance.

 E85 fuel (Flex-fuel vehicles)

E85 fuel is a blend of 85% ethanol and 15% gasoline. However, E85 does

not necessarily contain 85% ethanol. For example, in cold climates the etha-

nol content of E85 may be reduced during the winter months to maintain

cold weather starting performance.

E85 has less energy per gallon than gasoline, so you will need to fill your

fuel tank more frequently when using E85.

The number of fuel stations that sell E85 fuel is limited. For more information

about fueling stations, please refer to the U.S. Department of Energy Web

site.

http://www.afdc.energy.gov/afdc/locator/stations/

 Recommendation of the use of gasoline containing detergent additives

Toyota recommends the use of gasoline that contains detergent additives to

avoid 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

9

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.

604

 Non-recommendation of the use of blended gasoline (gasoline engine)

Use only gasoline containing up to 15%

ethanol.

DO NOT use gasoline contain-

ing more than 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).

(30% ethanol)

(50% ethanol)

(85% ethanol)

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.

 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.

 Non-recommendation of the use of after-market fuel additives (Flex-fuel

vehicles)

Do not use any after-market fuel additives when repeatedly refueling with

E85, as some after-market fuel additives are not compatible with E85.

 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.

605

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.

Gasoline engine: 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.

 When use of non-specified fuels (Flex-fuel engine)

The use of non-specified fuels will have a negative impact on starting and

driving performance, and will cause damage to the fuel system compo-

nents. Therefore, do not add fuels such as the following.

Fuels containing methanol

Fuels with more than 85% ethanol

 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.

Uniform Tire Quality Grading

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.

9

610

  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.

  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.
