*: The engine oil capacity is a reference quantity to be used when changing the engine 
oil. Warm up the engine and turn off the hybrid system, wait more than 5 minutes, and
check the oil level on the dipstick.
■Engine oil selection 
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus recom- 
mends the use of approved “Toyota Genuine Motor Oil”. Another motor oil of 
matching quality can also be used. 
Oil grade: 
0W-20, 5W-30 and 10W-30: 
API grade SL “Energy-Conserving”,  SM “Energy-Conserving” or SN 
“Resource-Conserving”; or ILSAC multigrade engine oil 
15W-40: 
API grade SL, SM or SN multigrade engine oil 
Recommended viscosity (SAE): 
SAE 0W-20 is filled into your Lexus 
vehicle at manufacturing, and the 
best choice for good fuel economy 
and good starting in cold weather. 
If SAE 0W-20 oil is not available, 
SAE 5W-30 oil may be used. How- 
ever, it should be replaced with SAE 
0W-20 at the next oil change. 
If you use SAE 10W-30 or a higher 
viscosity engine oil in extremely low 
temperatures, the engine may 
become difficult to start, so SAE 
0W-20 or 5W-30 engine oil is rec- 
ommended.
