Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps.
■If premium gasoline is not available
If this premium type cannot be obtained, you can use unleaded gasoline with a
Research Octane Number as low as 91.
The use of such gasoline may cause the engine to knock or drastically reduce out-
put to protect itself while driving with a heavy load. To avoid this, refill the tank with
premium unleaded gasoline as soon as possible.
■If your engine knocks
●Consult any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
●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.
EU area:
Your vehicle must use only unleaded gasoline conforming to European
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.

NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be dam-
aged.
●Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its effective-
ness and the emission control system to function improperly.
●Gasoline engine (EU area): Bioethanol fuel sold under names such as “E50” or
“E85” and fuel containing a large amount of ethanol should not be used. The use
of these fuels will damage the vehicle's fuel system. In case of any doubt, ask any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
●Gasoline engine (except EU area): Bioethanol fuel sold under names such as
“E50” or “E85” and fuel containing a large amount of ethanol should not be
used. Your vehicle can use gasoline mixed with 10% max ethanol. The use of fuel
with more than 10% ethanol content (E10) will damage the vehicle’s fuel system.
You must ensure that refueling is carried out only from a source where fuel speci-
fication and quality can be guaranteed. In case of any doubt, ask any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
