Fuel infor mation
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■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.
■Gasoline quality
In very few cases, driveability problems may be caused by the brand of gas-
oline you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your Toyota dealer.
■Gasoline quality standards
●Automotive manufacturers in the US, Europe and Japan have developed
a specification for fuel quality called World-Wide Fuel Charter (WWFC)
that is expected to be applied worldwide.
●The WWFC consists of four categories that are based on required emis-
sion levels. In the US, category 4 has been adopted.
●The WWFC improves air quality by lowering emissions in vehicle fleets,
and customer satisfaction through better performance.
Your vehicle must use only unleaded gasoline.
Select octane rating 87 (Research Octane Number 91) or higher. Use
of unleaded gasoline with an octane rating lower than 87 may result
in engine knocking. Persistent knocking can lead to engine damage.
At minimum, the gasoline you use should meet the specifications
of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.

■Toyota recommends the use of gasoline containing detergent additives
●Toyota recommends the use of gasoline that contains detergent additives
to avoid build-up of engine deposits.
●All gasoline sold in the US contains detergent additives to clean and/or
keep clean intake systems.
■Toyota recommends 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.
■Toyota does not recommend blended gasoline
●Toyota allows the use of oxygenate blended gasoline where the oxygen-
ate content is up to 10 % ethanol or 15 % MTBE.
●If you use gasohol in your Toyota, be sure that it has an octane rating no
lower than 87.
●Toyota does not recommend the use of gasoline containing methanol.
■Toyota does not recommend gasoline containing MMT
Some gasoline contains 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.

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 that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
●Use of unleaded gasoline with an octane rating lower than 87 may result in
engine knocking. Persistent knocking can lead to engine damage and
should be corrected by refueling with higher octane unleaded gasoline.
■Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (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.
