Maintenance and care
■Engine oil consumption
A certain amount o f 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 di sorders 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 oi l 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 ret ailer or Toyota
authorized repairer, or any reliable repairer, service station or auto
parts store for in formation concern-
ing recycling or disposal.
●Do not leave used e ngine 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 leve l 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

oil from the engine cover as soon as possible using a neutral detergent. Do
not use an organic solvent such as
brake cleaner.

6229-1. Specifications
before next oil change
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 indicates the
characteristic o f the oil which
allows cold startability. Oils with
a lower value before the W allow
for easier starting of the engine
in cold weather.
• The 16 in 0W-16 indicates the
viscosity characteristic of the oil
when the oil is at high tempera -
ture. An oil with a higher viscos -
ity (one with a higher value) may
be better suited if the vehicle is
operated at high speeds, or
under extreme load conditions.
How to read oil container labels:
Either or both API registered marks
are added to some oil containers to
help you select the oil you should
use.
API Service Symbol
Top portion: “API SERVICE SN” means
the oil quality designation by American
Petroleum Institute (API).
Center porti on: “SAE 0W-16” means
the SAE viscosity grade.
Lower portion: “Resource-Conserving”
means that the oil has fuel-saving and
environmental protection capabilities.
ILSAC Certification Mark
The International Lubricant Specifica -
tion Advisory Committee (ILSAC) Certi -
fication Mark is displayed on the front of
the container.
