in fuel tank pressure before refueling. To prevent fuel from spilling out, turn the cap
slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tank carefully and slowly.■

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 US, Europe and Japan have developed a
specification for fuel quality called the World-Wide Fuel Charter (WWFC) that
is expected to be applied worldwide.
●
The WWFC consists of four categories that are based on required emission
levels. In the US, category 4 has been adopted.
●
The WWFC improves air quality by lowering emissions in vehicle fleets, and
customer satisfaction th rough better performance.Your vehicle must use on ly unleaded gasoline.
Premium unleaded gasoline with an oc tane rating of 91 (Research Octane
Number 96) or higher required for optimum engine performance. If 91
octane cannot be obtained, you may us e unleaded gasoline with an octane
rating as low as 87 (Research Octane Number 91). Use of unleaded gaso-
line with an octane rating lower than 91 may result in engine knocking. Per-
sistent knocking can lead to engine damage and should be corrected by
refueling with higher octane unleaded gasoline.
At minimum, the gasoline you us e should meet the specifications of
ASTM D4814 in the U.S.A. an d CGSB3.5-M93 in Canada.
