If the oil level is below or only slightly above the low line,
add engine oil of the same type as already in the engine.
Remove the oil filler cap and add engine oil a little at a time,
checking the dipstick. We recommend that you use a funnel
when adding oil. The approximate quantity of oil needed to
raise the level between low line and full line on the dipstick is
indicated below for reference.
When the level reaches within the correct range, return the filler
cap and turn the cap clockwise until you hear a click.

Lexus approved Toyota Genuine Motor Oilº or equivalent to
satisfy the following grade and viscosity.
Oil grade: API grade SL Energy-Conservingº or ILSAC
multigrade engine oil.

62Z002
Outside temperature
SAE 5W-30 is the best choice, for good fuel economy and
good starting in cold weather.
If SAE 5W-30 oil is not available, SAE 10W-30 may be
used. However, it should be replaced with SAE 5W-30 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 anywhere on the outside
of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SL.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W-30. Energy-Conservingº, shown
in the lower portion, indicates that the oil has fuel-saving
capabilities.

CHECKING THE ENGINE COOLANT
LEVEL

1Reservoir cap2Fº (upper) line
3Lº (lower) line
Look at the see-through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the Fº and Lº lines on the reservoir. If the level
is low, add the coolant. (For the coolant type, see Coolant
type selectionº described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the Lº line,
add coolant. Bring the level up to the Fº line.
