■Oil capacity (Drain and

*)
*: The engine oil capacity is a refer-
ence quantity to be used when
changing the engine oil. Warm up
and turn off the engine, wait more
than 5 minutes, and check the oil
level on the dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is
used in your Toyota vehicle. Use
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to
satisfy the following grade and
viscosity.
Oil grade: ILSAC GF-6A multi-
grade engine oil
Recommended viscosity: SAE
0W-20 Outside temperature
SAE 0W-20 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is explained
here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil
which allows cold startability.
Oils with a lower value before
the W allow for easier starting
of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the
oil when the oil is at high tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if

4828-1. Specifications
■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 recomme nds 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 Gasoline and a list
of marketers, please 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).
●If you use gasohol in your vehicle,
be sure that it has an octane rat-
ing no lower than 87.
●Toyota does not recommend the
use of gasoline containing 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 re commend the use
of gasoline that contains MMT. If
fuel containing MMT is used, your
emission control system may be
Fuel infor mation
You must only use unleaded
gasoline.
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 knock-
ing. Persistent knocking
can lead to engine damage.
At minimum, the gasoline you
use should meet the specifica-
tions of ASTM D4814 in the
U.S.A.

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 driving 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 gasohol 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 l evel previously
stated will cause persistent
heavy knocking.
At worst, this will lead to engine
damage.
■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.

4888-1. Specifications
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law. Warning: The temperature grades
of a tire assume tha
t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
