84 1-6. Refueling
Closing the fuel tank capWhen replacing the fuel tank
cap, turn it until a clicking sound
is heard.
■Fuel type
Unleaded gasoline (Octane rating 87 [Research Octane Number 91] or
higher)
■ Fuel tank capacity
17.2 gal. (65 L, 14.3 Imp. gal.)
■ When the fuel filler door opener is inoperable
●Using the lever to open the fuel filler door may not allow for an adequate
reduction in fuel tank pressure before refueling. To prevent fuel from spill-
ing out, turn the cap slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air \
being
discharged from inside the fuel tank. Therefore, fill the fuel tank carefully
and slowly.
●If the fuel filler door opener switch
cannot be operated, contact your
Toyota dealer to service the vehicle.
In cases where refueling is urgently
necessary, the fuel filler door can be
opened using the lever in the trunk.

Fuel infor mation
■Fuel tank opening fo r 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 U.S., Europe and Japan have devel-
oped a specification for fuel quality called the 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 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.
You must only use unleaded gasoline in your vehicle.
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 kno cking 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 gaso line 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 U.S. 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 recomm end 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 recommen d 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.
