■Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Park the vehicle on level ground. After warming up the
engine and turning off the hybrid system, wait more than 5 minu tes, 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 equivalent to sat isfy
the following grade and viscosity.
Oil grade: API SN/RC multigrade engine oil
Recommended viscosity: SAE 0W-16
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.
Oil viscosity (0W-16 is expl ained here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which allows cold startability. Oils wi th a lower value before the W allow
for easier starting of the engine in cold weather.
• The 16 in 0W-16 indicates the vi scosity characteristic of the oil
when the oil is at high temperature. An oil with a higher visco sity
(one with a higher value) may be better suited if the vehicle i s
operated at high speeds, or un der extreme load conditions.
