WARNING
■When charging
Observe the following precautions.
Failure to do so may cause an unexpected accident, resulting in death or
serious injury.
● Connect to a power source suitable for charging. (P. 144)
● Check that the charging inlet, charging cable, plug and socket are free of
foreign matter.
● Only use sockets where the plug can be securely inserted.
● Do not charge if the charging cable is coiled or bundled.
● Wrapping the charging cable while in-use is not recommended because
cable may overheat. Failure to rewrap charging cable when not in-use
could result in strangulation or tripping hazard.
● Do not wash the vehicle while the charging cable is connected to the vehi-
cle and when the charging lid is open.
● Do not touch the terminals of the charging connector and charging inlet
with a sharp metal objects (needles etc.) or hands, or short them with for-
eign objects.
● When charging outdoors, make sure to connect to a rain-tight socket for
outdoor use.
● Do not insert the plug if the socket is submerged in water or snow.
● Follow these points when charging while it is raining or snowing.
• Check that no snow, water or ice has accumulated around the charging
connector terminals and the vehicle charging inlet. Tap snow, water or
ice gently from connector prior to inserting charging connector into the
vehicle’s charging inlet.
• Do not connect the plug if your hands are wet. Also, do not get the plug
or socket wet.
● Do not charge the vehicle during a lightning storm.
● Do not let the wheels on the charging cable, plug, charging connector and
CCID (Charging Circuit Interrupting Device).
● Firmly insert the plug into the socket.

Maintenance and care
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressure. Whenever
wheels are replaced, tire pressure warning valves and transmitters must be
installed. ( P. 607)
WARNING
■When replacing wheels
● Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
■ When installing the wheel nuts
● Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
■ Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
● Be sure to install the wheel nuts with the
tapered ends facing inward. Installing
the nuts with the tapered ends facing
outward can cause the wheel to break
and eventually cause the wheel to come
off while driving, which could lead to an
accident resulting in death or serious
injury.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 oil is not avail-
able, SAE 5W-30 oil may be
used. However, it should be
replaced with SAE 0W-20 at the
next oil change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become difficult
to start, so SAE 0W-20 or 5W-
30 engine oil is recommended.
