■Gasoline quality
In very few cases, driveability prob-
lems may be caused by the brand of
gasoline you are using. If driveability
problems persist, try changing the
brand of gasoline. If this does not
correct the problem, consult your Toyota dealer.
■Recommendation of the use of
gasoline containing detergent
additives
●Toyota recommends the use of
gasoline that contains detergent
additives to avoid the build-up of
engine deposits.
●All gasoline sold in the U.S.A. con-
tains minimum detergent additives
to clean and/or keep clean intake
systems, per EPA’s lowest addi-
tives concentration program.
●Toyota strongly recommends the
use of Top Tier Detergent Gaso-
line. For more information on Top
Tier Detergent Gas
oline and a list
of marketers, pleas e go to the offi-
cial website www.toptiergas.com.
■Recommendation of the use of
low emissions gasoline
Gasolines containing oxygenates
such as ethers and ethanol, as well
as reformulated gasolines, are avail-
able in some cities. These fuels are
typically acceptable for use, provid-
ing they meet other fuel require-
ments.
Toyota recommends these fuels,
since the formulations allow for
reduced vehicle emissions.
■Non-recommendation of the
use of blended gasoline
●Use only gasoline containing up to
15% ethanol.
DO NOT use any flex-fuel or gas-
oline that could contain more than
15% ethanol, including from any
pump labeled E30 (30% ethanol
[ ]), E50 (50% ethanol [ ]), E85
(85% ethanol [ ]) (which are only
some examples of f uel containing
more than 15% ethanol).
Fuel infor mation
You must only use unleaded
gasoline.
The engine is designed to
operate at maximum perfor-
mance using unleaded gas-
oline with an octane rating
of 93 (98 RON) or higher. If
an octane rating of 93 (98
RON) fuel is not readily
available in your area,
unleaded gasoline with an
octane rating of 91 (95 RON)
may be used with no detri-
ment to engine durability or
driveability. However, you
may notice a slight
decrease in maximum
engine performance and
you may hear some knock-
ing (pinging) of an engine
while using an octane rating
of 91 (95 RON) fuel.
If the octane rating is less
than 91, damage to the
engine may occur and may
void the vehicle warranty.
At minimum, the gasoline
you use should meet the
specifications of ASTM
D4814 in the U.S.A..

Vehicle specifications
●If you use gasohol in your vehicle,
be sure that it has an octane rat-
ing no lower than 91.
●Toyota does not recommend the
use of gasoline co ntaining metha-
nol.
■Non-recommendation of the
use of gasoline containing MMT
Some gasoline contains an octane
enhancing additive called MMT
(Methylcyclopentadienyl Manga-
nese 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.
■If your engine knocks
●Consult your Toyota dealer.
●You may occasionally notice light
knocking for a short time while
accelerating or dr iving uphill. This
is normal and there is no need for
concern.
NOTICE
■Notice on fuel quality
●Do not use impro per 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 gasoho l other than
the type previously stated.
Other gasohol may cause fuel
system damage or vehicle per-
formance problems.
●Using unleaded gasoline with
an octane number or rating
lower than the level previously
stated may cause persistent
heavy knocking.
At worst, this may lead to
engine damage and will void the
vehicle warranty.
■When refueling with gasohol
Take care not to spill gasohol. It
can damage your vehicle’s paint.
■Fuel-related poor driveability
If poor driveability (poor hot start-
ing, vaporization, engine knock-
ing, etc.) is encountered after
using a different type of fuel, dis-
continue the use of that type of
fuel.
