your Toyota vehicle. Use Toyota approved

Recommended viscosity:
SAE 5W30
oil008
Temperature range anticipated before next
oil change
SAE 5W30 is the best choice, for good
fuel economy, and good starting in cold
weather. If SAE 5W30 oil is not available, SAE
10W30 oil may be used. However, it
should be replaced with SAE 5W30 at
the next oil change.

Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SL. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W30. “Energy
Conserving” shown in the lower portion,
indicates that the oil has fuelsaving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.
To ensure excellent lubrication perfor-
mance for your engine, the “Toyota Genu-
ine Motor Oil” range is available, which
has been specifically tested and approved
for all Toyota engines.
Please contact your Toyota dealer for fur-
ther details of the “Toyota Genuine Motor
Oil” range.Look at the seethrough coolant reser-
voir when the hybrid system is cold.
The coolant level is satisfactory if it is
between the “FULL” and “LOW” lines
on the reservoir. If the level is low, add
ethyleneglycol type coolant for a prop-
er corrosion protection of aluminum
components.
The coolant level in the reservoir will vary
with hybrid system temperature. However,
if the level is on or below the “LOW” line,
add coolant. Bring the level up to the
“FULL” line.
Always use ethyleneglycol type coolant
for a proper corrosion protection of alumi-
num components. See information in the
next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
