1-7. Refueling
Opening the fuel tank cap
The fuel tank of your vehicle has a special structure, which requires
a reduction in fuel tank pressure before refueling. After the opener
switch has been pressed, it will take several seconds until the vehi-
cle is ready for refueling.
■Before refueling the vehicle
●Turn the “POWER” switch off and close all the doors and win-
dows.
●Confirm the type of fuel. (→P. 1 8 0 )
■Opening the fuel tank cap
Press the fuel filler door
opener switch.
The screen to the left is dis-
played for a short period. Wait
until “REFUEL READY” is dis-
played, then proceed to the
next step.

■Fuel types
Use unleaded gasoline. (Octane rating 87 [Research Octane Number 91] or
higher)
■If the fuel filler door opener is inoperable
If the fuel filler door opener switch cannot be operated, contact your Toyota
dealer. In the event that urgent refueling is required, follow the procedure
below.
Remove the cap slowly. Take care to prevent fuel from spilling
out, as fuel tank pressure may not have been adequately
reduced.
Fill the fuel tank carefully and slowly. Use caution, as air being
discharged from inside the fuel tank may cause fuel to spray out
from the filler opening during refueling.
Open the fuel filler door using the lever in
the luggage compartment.STEP 1

NOTICE
■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.

■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.

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
