■Gasoline quality standards
● Automotive manufacturers in the U.S.A., Europe and Japan have devel-
oped 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 emis-
sion 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.
■ Recommendation of the use of gaso line containing detergent additives
● Toyota recommends the use of gasoline that contains detergent additives
to avoid the 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 con-
centration 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
● 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 (Methyl-
cyclopentadienyl 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.
■ If your engine knocks
● Consult your Toyota dealer.
● 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.
●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
containing more than
10% ethanol.
(15% ethanol)
(50% ethanol)
(85% ethanol)

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 can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related p oor driveability
If poor driveability is encountered after using a different type of fuel (poor hot
starting, vaporization, engine knocking, etc.), discontinue the use of that type
of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
■ Notice about fuel
For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal. (20 L, 4.4 Imp.gal.) of fuel every 6 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 6-month period), as this
may affect components of the fuel system or the gasoline engine.
