Fuel
FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups,
your Toyota has a new smaller fuel
tank opening. The special nozzle on
pumps with unleaded fuel will fit it,
but the larger standard nozzle on
pumps with leaded gas will not.
At a minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A. and CGSB
3.5- M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause thethree- way catalytic converter to
lose its effectiveness and the
emission control system to func-tion improperly. Also, this can in-crease maintenance costs.
OCTANE RATING
Select Octane Rating 87 (Research
Octane Number 91) or higher.
Use of unleaded gasoline with an oc-
tane rating or research octane number
lower than stated above will cause
persistent heavy knocking. If it is se-
vere, this will lead to engine damage.
If your engine knocks...
If you detect heavy knocking even
when using the recommended fuel, or
if you hear steady knocking while
holding a steady speed on level
roads, consult your Toyota dealer.
However, now and then, you may no-
tice light knocking for a short time
while accelerating or driving up hills.
This is no need of concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gaso-
lines that contain detergent addi-
tives to avoid build- up of engine
deposits.
For further details, ask your Toyota
dealer or a local gasoline retailer. IMPROVED GASOLINES
The American Automobile Manufac-
turers Association (AAMA) has de-
veloped a specification of improved
gasolines. The AAMA specification
offers optimal fuel information for
better vehicle performance and bet-
ter protection of your engine.
Toyota recommends the use of gaso-
lines that meet the AAMA specifica-
tion, if available, for improved drive-
ability and emission control system.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Meth-
yl Tertiary- Butyl Ether) are available
in the market. If you use a gasoline
mixed with MTBE, make certain that
it does not contain more than 15%
of MTBE.
If the use of gasolines containing
MTBE causes poor driveability and/or
poor fuel economy, you should discon-
tinue the use of fuels containingMTBE.

GASOLINES CONTAINING MMT
Some gasolines contain an
octane- enhancing additive called
MMT (methylcyclopentadienyl
manganese tricarbonyl).
Toyota does not recommend the use
of gasolines that contain MMT. If fuels
containing MMT are used, your emis-
sion 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.
GASOLINES CONTAINING ALCOHOL
If you use gasohol in your Toyota,
be sure that it is unleaded, has an
octane rating no lower than 87 and
does not contain more than 10%
ethanol.
Gasohol is a mixture of gasoline and
ethanol.
Toyota does not recommend the use
of gasolines containing methanol. If
you use gasoline containing methanol,
use only gasoline meeting the require-
ments above and also containing less
than 5% methanol with cosolvents and
corrosion inhibitors for methanol.NOTICE
Do not use gasohol other than
stated above. It will cause fuelsystem damage or vehicle per-formance problems.
If driveab ility problems occur
(poor hot starting, vaporizing, engine knock, etc.), discontinue
the use.
Take care not to spill gasoholduring refueling. Gasohol maycause paint damage.
FUEL TANK CAPACITY
70 L (18.5 gal., 15.4 Imp. gal.) Operation in foreign coun-
tries
If you plan to drive your Toyota in
another country...
First,
comply with the vehicle registra-
tion laws.Second, confirm the availability of the
correct fuel (unleaded and minimum
octane number).
