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.
NOTICE
Notice on fuel quality
Do not use improper fuels. If improper fuels are used the engine will be
damaged.
Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its
effectiveness and emission control system to function improperly.
EU area:
Your vehicle must use only unleaded gasoline conforming to Euro-
pean standard EN228. For optimum engine performance, select
unleaded gasoline with a Research Octane Number of 95 or higher.
Except EU area:
Your vehicle must use only unleaded gasoline. For optimum engine
performance, select unleaded gasoline with a Research Octane
Number of 95 or higher.
