Fuel information
■Fuel tank opening for unleaded gasoline
To h e l p p r e v e n t i n c o r r e c t f u e l i n g , y o u r v e h i c l e h a s a f u e l t a n k o p e n i n g t h a t
only accommodates the special nozzle on unleaded fuel pumps.
■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.
Yo u m u s t o n l y u s e u n l e a d e d g a s o l i n e i n y o u r v e h i c l e .
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.

■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 gasoline containing detergent additives
●To y o t a r e c o m m e n d s t h e u s e o f g a s o l i n e t h a t c o n t a i n s d e t e r g e n t a d d i t i v e s
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.
●To y o t a s t r o n g l y r e c o m m e n d s t h e u s e o f To p T i e r D e t e r g e n t G a s o l i n e . F o r

■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.
To y o t a r e c o m m e n d s t h e u s e o f c l e a n e r b u r n i n g g a s o l i n e a n d a p p r o p r i a t e l y
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.
●To y o t a d o e s n o t r e c o m m e n d t h e u s e o f g a s o l i n e c o n t a i n i n g m e t h a n o l .
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methyl-
cyclopentadienyl Manganese Tricarbonyl).
To y o t a d o e s n o t r e c o m m e n d t h e u s e o f g a s o l i n e t h a t c o n t a i n s M M T. I f f u e l
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.
●Yo u m a y o c c a s i o n a l l y n o t i c e l i g h t k n o c k i n g f o r a s h o r t t i m e w h i l e a c c e l e r -
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 poor 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
Ta k e c a r e n o t t o s p i l l g a s o h o l . I t c a n d a m a g e y o u r v e h i c l e ’ s p a i n t .
■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.
