■Checking the engine oil
1Park the vehicle on level
ground. After warming up the
engine and turning off the hybrid
system, wait more than 5 min-
utes for the oil to drain back into
the bottom of the engine.
2Holding a rag under the end,
pull the dipstick out.
3Wipe the dipstick clean.
4Reinsert the dipstick fully.
5Holding a rag under the end,
pull the dipstick out and check
the oil level.

The shape of the dipstick may differ depending on the type of vehicle or
engine.
6Wipe the dipstick and reinsert it
fully.
■Checking the oil type and pre-
paring the items needed
Make sure to check the oil type and
prepare the items needed before
adding oil.

■Adding engine oil
If the oil level is below or near the
low level mark, add engine oil of the
same type as that already in the
engine.
1Remove the oil filler cap by turn-
ing it counterclockwise.
2Add engine oil slowly, checking
the dipstick.

Maintenance and care
■Engine oil consumption
A certain amount of engine oil will be
consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance inter- vals.
●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 inappropri-ate viscosity is used
●When driving at high engine speeds or with a heavy load, when towing, or
when driving while accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently through heavy traffic
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir when the
hybrid system is cold.

WARNING
■Used engine oil
●Used engine oil contains poten-
tially harmful contaminants which may cause skin disorders such as inflammation and skin cancer, so
care should be taken to avoid pro- longed and repeated contact. To remove used engine oil from your
skin, wash thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dispose of used oil and fil-
ters in household trash, in sewers or onto the ground. Call any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer, service station or auto parts store for information concern-
ing recycling or disposal.
●Do not leave used engine oil within
the reach of children.
NOTICE
■To prevent serious engine dam- age
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
●Avoid overfilling, or the engine could be damaged.
●Check the oil level on the dipstick every time you refill the vehicle.
●Be sure the engine oil filler cap is properly tightened.
■If oil is spilled on the engine cover
To prevent the engine cover from
being damaged, remove any engine oil from the engine cover as soon as possible using a neutral detergent. Do
not use an organic solvent such as brake cleaner.

■Oil capacity (Drain and refill reference*)
*: 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 Toyota vehicle. Toyota rec-
ommends the use of approved
“Toyota Genuine Motor Oil”.
Another motor oil of matching qual-
ity can also be used.
Oil grade:
0W-16:
API grade SN “Resource-Conserv-
ing”, SN PLUS “Resource-Conserv-
ing” or SP “Resource-Conserving”;
or ILSAC GF-6B multigrade engine
oil
0W-20 and 5W-30:
API grade SM “Energy-Conserv-
ing”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving”
or SP “Resource-Conserving”; or
ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-16 is filled into your
Toyota vehicle at manufacturing,
and the best choice for good fuel economy and good starting in cold
weather.
If SAE 0W-16 oil is not available,
SAE 0W-20 oil may be used. How-
ever, it should be replaced with
SAE 0W-16 at the next oil change.
Temperature range anticipated
before next oil change
Preferred
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 indicates the
characteristic of the oil which
allows cold startability. Oils with
a lower value before the W allow
for easier starting of the engine
