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.

■ 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.
■ 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.
