Leaded gasoline will cause the three-way catalytic converter to lose its effectiveness
and the emission control system to function improperly.
●EU area: Bioethanol fuel sold under names such as “E50” or “E85” and fuel contain-
ing 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 professional.
●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 gaso-

(E10) will damage the vehicle’s fuel system. You must ensure that refueling is carried
out only from a source where fuel specification and quality can be guaranteed. In case
of any doubt, ask any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
