■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ 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.
■ Gasoline quality standards
●Automotive manufacturers in the U.S.A., Europe and Japan have developed
a specification for fuel quality call ed the World-Wide Fuel Charter (WWFC),
which is expected to be applied worldwide.
● The WWFC consists of four categorie s 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.
Fuel infor mation

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. and CGSB3.5-M93 in Canada.
