7-3. Do-it-yourself maintenance
■ Engine oil consumption
A certain amount of engine oil will
be consumed while driving. In the
following situations, oil consump-
tion may increase, and engine oil
may need to be refilled in between
oil maintenance intervals.
● 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 inap-
propriate 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 fre-
quently 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 prolonged 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 filters in household trash,
in sewers or onto the ground.
Call your Toyota dealer, service
station or auto parts store for
information concerning recy-
cling or disposal.
● Do not leave used engine oil
within the reach of children.
NOTICE
■ To prevent serious engine
damage
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 dip-
stick 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 neu-
tral detergent. Do not use an
organic solvent such as brake
cleaner.
