Vehicle specifications
■Gasoline quality standards
●Automotive manufacturers in the U.S.A., Europe and Japan have developed
a specification for fuel quality called the World-Wide Fuel Charter (WWFC),
which is expected to be applied worldwide.
● The WWFC consists of four categories that are based on required emission
levels. In the U.S., category 4 has been adopted.
● The WWFC improves air quality by lowering emissions in vehicle fleets, and
improves customer satisfaction through better performance.
■ E85 fuel (Flex-fuel vehicles)
●E85 fuel is a blend of 85% ethanol and 15% gasoline. However, E85 does
not necessarily contain 85% ethanol. For example, in cold climates the etha-
nol content of E85 may be reduced during the winter months to maintain
cold weather starting performance.
● E85 has less energy per gallon than gasoline, so you will need to fill your
fuel tank more frequently when using E85.
● The number of fuel stations that sell E85 fuel is limited. For more information
about fueling stations, please refer to the U.S. Department of Energy Web
site.

■ Recommendation of the use of gaso line containing detergent additives
● Toyota recommends the use of gasoline detergent additives to avoid build-
up of engine deposits.
● All gasoline sold in the U.S.A. contains minimum detergent additives to
clean and/or keep clean intake systems, per EPA’s lowest additives concen-
tration program.
● Toyota strongly recommends the use of Top Tier Detergent Gasoline. For
more information on Top Tier Detergent Gasoline and a list of marketers,
please go to the official website www.toptiergas.com.
■ Recommendation of the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxy-
genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in
many areas.
Toyota recommends the use of cleaner burning gasoline and appropriately
blended reformulated gasoline. These types of gasoline provide excellent
vehicle performance, reduce vehicle emissions and improve air quality.

■Non-recommendation of the use of blended gasoline (gasoline engine)
●If you use gasohol in your vehicle, be sure that it has an octane rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methanol.
■ Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If this
happens, contact your Toyota dealer for service.
■ Toyota does not recommend blende d gasoline (Flex-fuel engine)
Do not use non-specified fuels such as the following.
● Fuels containing methanol.
● Fuels with more than 85% ethanol.
■ Toyota does not recommend the use of after-market fuel additives (Flex-
fuel engine)
Do not use any after-market fuel additives when repeatedly refueling with
E85, as some after-market fuel additives are not compatible with E85.
■ If your engine knocks
●Consult your Toyota dealer.
● 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.
●
Use only gasoline containing a maxi-
mum of 10% ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 10% etha-
nol, including from any pump labeled
E15, E30, E50, E85 (which are only
some examples of fuel containing more
than 10% ethanol).
DO NOT use gasoline contain-
ing more than 10% ethanol.
(15% ethanol)
(50% ethanol)
(85% ethanol)
