CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
■When working on the engine compartment
●Vehicles without a smart key system: Make sure that the engine switch is
in the “LOCK” position and the “READY” indicator is off.
Vehicles with a smart key system: Make sure that the indicator on the
“POWER” switch and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fans and engine
drive belt.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■ When working near the electric c ooling fans or radiator grille
Vehicles without a smart key system: The electric cooling fan may keep
rotating for about 3 minutes even after the engine switch is turned to the
“LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. Be sure the engine switch is in the “LOCK” position when
working near the electric cooling fan or radiator grille.
Vehicles with a smart key system: The electric cooling fan may keep rotating
for about 3 minutes even after the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. Be sure the “POWER” switch is off when working near the
electric cooling fans or radiator grille.

and turning off the hybrid system, wait more than 5 minutes
for the oil to drain back in to the bottom of the engine.
Holding a rag under the end, pull
the dipstick out.
Wipe the dipstick clean.

Maintenance and care

Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
● More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
● A new engine consumes more oil.
● When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
● Oil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/
1000 km)
● If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600
miles (1000 km), contact your Toyota dealer.
CAUTION
■Used engine oil
●Used engine oil contains potentially 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 recycling or disposal.
● Do not leave used engine oil within the reach of children.

● Be sure the engine oil filler cap is properly tightened.
