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..

■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.

■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

■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

●Use only gasoline containing up to 15%

DO NOT use gasoline

containing more than

15% ethanol.

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)

■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.
