Fuel infor mation
■Fuel tank opening fo r unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ If your engine knocks
● Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time while acceler-
ating 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 Toyota dealer.
Your vehicle must use only 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 kno cking 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.
