2 Holding a rag under the end,
pull the dipstick out.
3 Wipe the dipstick clean.

■Engine oil consumption
A certain amount of engine oil will
be consumed while driving. In the
following situations, oil consump-
tion may increase, and engine oil
may need to be re filled in between
oil maintenance intervals.
●When the engine is new, for
example directly after purchasing
the vehicle or after replacing the
engine
●If low quality oil or oil of an inap-
propriate viscosity is used
●When driving at high engine
speeds or with a heavy load, or
when driving while accelerating or
decelerating frequently
●When leaving the engine idling for
a long time, or when driving fre-
quently through heavy traffic
■Engine oil level rise
If the vehicle is repeatedly driven
without the engine warmed up,
moisture caused by dew condensa-
tion inside the engine or fuel which
did not burn mixes into the engine
oil, resulting in a rise in engine oil
level.
However, this is not a malfunction.
For example, the engine become
difficult to be warmed up in the fol-
lowing situations.
●When driving a short distance
●When driving at a low speed
●When the outside temperature is
low

■Oil capacity (Drain and refill  reference*)
*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. When actually adding the engine oil, make sure that the oil
level is between the low level ma rk and refill upper limit mark (P.506).
Warm up and turn off the hybrid syst em, wait about 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
Genuine Motor Oil” or equiva-
lent to satisfy the following
grade and viscosity.
Oil grade:
ILSAC GF-6B multigrade engine

SAE 0W-16 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
with SAE 0W-16 at the next oil
change.
