Fuel infor mation
Fuel tank opening for 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 any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
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.
The engine is designed to operate at maximum performance using
unleaded gasoline with an octane rating of 98 or higher. If 98 RON
fuel is not readily available in your area, unleaded gasoline with an
octane rating of 95 RON may be used with no detriment to engine
durability or driveability. However, you may notice a slight decrease
in maximum engine performance and you may hear some knocking
(pinking) of an engine while using 95 RON fuel. Use of 95 RON fuel
will not affect your warranty coverage.
