Maintenance and care
WARNING
●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 12- volt battery. Fuel and 12-volt battery fumes are flammable.
●Be extremely cautious when work-ing on the 12-volt battery. It con-
tains poisonous and corrosive sulfuric acid.
●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.329)
■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.

■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
(vehicles with towing packages), or when driving while accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
■After changing the engine oil
The engine oil maintenance data should be reset. Perform the following proce-
dures:
1 Press / (vertical display) or
/ (horizontal display) of the
meter control switch to select .
2 Press / (vertical display) or

3 Press / to select “Oil Mainte-
nance” and then press .
4 Press / to select “Yes” and
then press .
A message will be displayed on the multi-information display when the reset
procedure has been completed.
■Engine coolant reservoir
The coolant level is satisfactory if it
is between the “F” and “L” lines on
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 authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer, service station or auto parts store for information
concerning 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.

■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 turn off the hybrid system, wait
more than 5 minutes, and check the
oil level on the dipstick.
■Engine oil selection
Gasoline Engine
“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-8: JASO GLV-1
0W-16:
API grade SN “Resource-Conserv-
ing”, SN PLUS “Resource-Conserv-

or ILSAC GF-6B multigrade engine

0W-20 and 5W-30:

ing”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving”
or SP “Resource-Conserving”; or
ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
Preferred
Temperature range anticipated
before next oil change
SAE 0W-8 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-8 oil is not available, SAE
0W-16 or 0W-20 oil may be used.
However, it should be replaced with
SAE 0W-8 at the next oil change.
Oil viscosity (0W-8 is explained
here as an example):
• The 0W in 0W-8 indicates the
characteristic of 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 8 in 0W-8 indicates the vis-
cosity 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
