■Usable portable devices
●Qi standard wireless charge standard
can be used on compatible devices.
However, not all Qi standard devices
and compatibility are guaranteed.
●Starting with mobile phones and
smartphones, it is aimed for low
power electrically supplied portable
devices of no more than 5W.
●However, charging exceeding 5 W is
supported by the following portable
devices.
• Charging at 7.5 W or less is supported
by iPhone’s that support 7.5 W
charging.
• Charging at 10 W or less is supported
by portable devices compliant with
EPP output as defined by WPC stan-
dard Ver1.2.4.
■Using the smart entry & start sys-
tem
If the smart entry & start system detects
the key while a device is being charged,
charging will be temporarily stopped.
■When covers and accessories are
attached to portable devices
Do not charge in situations where cover
and accessories not able to handle Qi
are attached to the portable device.
Depending on the type of cover (includ-
ing the certain genuine manufacture
parts) and accessory, it may not be pos-
sible to charge. When charging is not
performed even with the portable device
placed on the charge area, remove the
cover and accessories.
■Important points of the wireless
charger
●If the electronic key cannot be
detected within the vehicle interior,
charging cannot be done. When the
door is opened and closed, charging
may be temporarily suspended.

Remove the for-
eign substance
from the charge
area.

Maintenance and care
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. Fuel 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.482)
■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.

■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
“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”, SN PLUS “Resource-Conserv-
ing” or SP “Resource-Conserving”;
or ILSAC GF-6B multigrade engine
oil
0W-20 and 5W-30:
API grade SM “Energy-Conserv-
ing”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving”
or SP “Resource-Conserving”; or
ILSAC GF-6A 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.
Temperature range anticipated
before next oil change
Preferred
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 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
