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 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
■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
DO NOT use any flex-fuel or gasoline that could contain more than 15% ethanol, including from any pump labeled E30, E50, E85 (which are only some examples of fuel containing more than 15% ethanol).
■Non-recommendation of the use of gasoline containing MMT Some gasoline contains an octane enhancing additive called MMT (Methylcyclopentadienyl 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
■Notice on fuel quality
Leaded gasoline can cause damage to your vehicle's three-way catalytic converters causing the emission control system to malfunction.
Other gasohol may cause fuel system damage or vehicle performance problems.
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.
