Lubrication system■ Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 5W-30
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 5W-30 is not available,
SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
Fuel typeUnleaded gasoline only

Oil viscosity (5W-30 is explained here as an example):
●
The 5W in 5W-30 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 30 in 5W-30 indicates the viscosity characteristic of the oil when
the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high
speeds, or under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubric ant Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.

• “Toyota Super Long Life Coolant”
• A similar high-quality ethylene glycol-based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life
hybrid organic acid technology
Do not use plain water alone.

Fuel information
■Fuel tank opening fo r unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ 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.A., Europe and Japan have devel-
oped a specification for fuel quality called 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 gaso line 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. contains detergent additives to clean and/
or keep clean intake systems.
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.

■
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.
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
Take care not to spill gasohol. It can damage your vehicle’s paint.

Warning: The temperature grades of a tire assume that 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.
