■Use of ethanol blended gasoline in a gasoline engine
Toyota allows the use of ethanol blended gasoline where the ethanol content
is up to 10%. Make sure that the ethanol blended gasoline to be used has a
Research Octane Number that follows the above.
■ If you plan to drive in foreign countries (vehicles with DPF system)
Low sulfur diesel fuel may not be avai lable, so please check the availability
with your distributor.
■ If your engine knocks
● Consult any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
● You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.
NOTICE
■ Notice on gasoline fuel quality
● Do not use improper fuels. If improper fuels are used, the engine will be
damaged.
● Do not use gasoline with metallic additives, for example manganese, iron
or lead, otherwise it may cause damage on your engine or emission con-
trol system.
● Do not add aftermarket fuel additives which contain metallic additives.
● Do not use the methanol blended gasoline such as M15, M85, M100. The
use of gasoline containing methanol may cause engine damage or failure.
● Bioethanol fuel sold under names such as “E50” or “E85” and fuel contain-
ing 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 specifica-
tion and quality can be guaranteed. In case of any doubt, ask any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
