Your vehicle must use only unleaded gasoline.

Premium unleaded gasoline with an octane rating of 91 (Research Octane Number 96) or higher required for optimum engine perfor- mance. If 91 octane cannot be obtained, you may use unleaded gaso- line 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 dam- age and should be corrected by refueling with higher octane unleaded gasoline.

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

- 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
l Consult your Lexus dealer.
l You may occasionally notice light knocking for a short time while accel- erating 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 gas- oline 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
l Automotive manufacturers in the US, Europe and Japan have developed a specification for fuel quality called World-Wide Fuel Charter (WWFC) that is expected to be applied worldwide.

l The WWFC consists of four categories that are based on required emis- sion levels. In the US, category 4 has been adopted.

l The WWFC improves air quality by lowering emissions in vehicle fleets, and customer satisfaction through better performance.

- Lexus recommends the use of gasoline containing detergent additives
l Lexus recommends the use of gasoline that contains detergent additives to avoid build-up of engine deposits.

l All gasoline sold in the US contains detergent additives to clean and/or keep clean intake systems.

- Lexus recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxygenates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is avail- able in many areas.

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

- Lexus does not recommend blended gasoline

l Use only gasoline containing a maxi- mum 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).

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

l Lexus DOES NOT recommend the use of gasoline containing methanol.

- Lexus does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy clopentadienyl Manganese Tricarbonyl).

Lexus 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 Lexus dealer for service.

NOTICE

- Notice on fuel quality
l Do not use improper fuels. If improper fuels are used the engine will be damaged.

l 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.

l Do not use gasohol other than that stated here.

Other gasohol may cause fuel system damage or vehicle performance problems.

l Using unleaded gasoline with an octane number or rating lower than that stated here will cause persistent heavy knocking.

At worst, this will lead to engine damage.

- Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor hot starting, 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.
