You must only use unleaded gasoline in your vehicle.

Select premium unleaded gasoline with an octane rating of 91 (Research Octane Number 96) or higher required for optimum engine performance.

If 91 octane cannot be obtained, you may use unleaded gasoline with an octane rating as low as 87 (Research Octane Number 91). Use of unleaded gasoline with an octane rating lower than 91 may result in engine knocking. Persistent knocking can lead to engine damage and should be corrected by refueling with higher octane unleaded gasoline.

At minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.

 - Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your Lexus has a fuel tank opening that only accommodates the special nozzle on unleaded fuel pumps.

 - If your engine knocks

• Consult your Lexus 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.

 - 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 Lexus 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.

 - Recommendation of the use of gasoline containing detergent additives

• Lexus 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 detergent additives to clean and/or keep clean intake systems.

 - Recommendation of the use of cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxygen- ates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas.

Lexus recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle perfor- mance, reduce vehicle emissions and improve air quality.

 - Non-recommendation of the use of blended gasoline

• Use only gasoline containing a maximum of 10 % ethanol.

DO NOT use any flex-fuel or gasoline that could contain more than 10 % etha- nol, including from any pump labeled E15, E30, E50, E85 (which are only some examples of fuel containing more than 10% ethanol).

• If you use gasohol in your Lexus, be sure that it has an octane rating no lower than 87.

• Lexus does not recommend the use of gasoline containing methanol.• If you use gasohol in your Lexus, be sure that it has an octane rating no lower than 87.

• Lexus 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 clo- pentadienyl Manganese Tricarbonyl).

Lexus does not recommend the use of gasoline that contains MMT. If fuel contain- ing MMT is used, your emission control system may be adversely affected.

The malfunction indicator lamp on the instrument cluster may come on. If this hap- pens, contact your Lexus dealer for service.

NOTICE

 - Notice on fuel quality

• Do not use improper fuels. If improper fuels are used, the engine will be dam- aged.

• Do not use leaded gasoline.

Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert- ers 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 is encountered after using a different type of fuel (poor hot start- ing, vaporization, engine knocking, etc.), discontinue the use of that type of fuel.

 - When refueling with gasohole

Take care not to spill gasohol. It can damage your vehicle’s paint.
