WARNING
■When working on the engine compartment
●Make sure that “IGNITION ON” on the multi-information display and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan.
●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 flu-ids 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 or the 12-volt battery. Fuel and 12-volt battery fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and dam-
age painted surfaces. If fluid gets on your hands or in your eyes, flush the affected area with clean water
immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fan or radiator grille
Be sure the power switch is off.
With the power switch in ON, the electric cooling fan may automatically start to run if the air conditioning is on
and/or the coolant temperature is high. ( P.504)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.,
from getting in your eyes.
NOTICE
■If you remove the air cleaner fil- ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.

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.

control with full-speed range (if
equipped) is operating. If a warning
message is shown, be sure to deceler-
ate the vehicle or follow an instruction
shown on the multi-information display.
• A warning message is shown when
Brake Override System operates. ( P.301, 574) • A warning message is shown when

on the multi-information display.
●If a message about an operation of
the power switch is shown
An instruction for operation of the power
switch is shown when the incorrect pro-
cedure for starting the hybrid system is

■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 turning 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” or SN PLUS “Resource-Con-
serving” multigrade engine oil
0W-20 and 5W-30:
API grade SL “Energy-Conserving”,
SM “Energy-Conserving”, SN
“Resource-Conserving” or SN
PLUS “Resource-Conserving”; or
ILSAC 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.
