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. 122)
● Check that the charging inlet, charging cable, plug and outlet are free of
foreign matter.
● Only use outlets where the plug can be securely inserted.
● Do not charge if the charging cable is coiled or bundled.
● Wrapping 120 V 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 weatherproof outlet
for outdoor use.
● Do not insert the plug if the outlet 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 outlet 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 outlet.
● Do not use an extension cord and converting adaptor.

7-2. Maintenance
■Repair and replacement
It is recommended that genuine Toyota parts be used for repairs to ensure
performance of each system. If non-Toyota parts are used in replacement or if
a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
■ Resetting the message indicating maintenance is required (U.S.A. only)
After the required maintenance is preformed according to the maintenance
schedule, please reset the message.
To reset the message, follow the procedures described below:
While the hybrid system is operating, switch the multi-information display to
the screen. ( →P. 231)
Select “ (Vehicle Settings)”, and then press .
Select “Maintenance System”, and then press .
Select “Oil Maintenance”, and then press .
Select “Yes”, and then press .
■ Allow inspection and repairs to be performed by a Toyota dealer
●Toyota technicians are well-trained specialists and are kept up to date with
the latest service information. They are well informed about the operation of
all systems on your vehicle.
● Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty cove rage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will promptly take
care of it.
A message will be displayed when the

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 trans-
mitters must be installed. ( →P. 595)
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 leak ing wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous 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
accident 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.Tapered

Engine oil selection
“Toyota Genuine Motor Oil” is us ed in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 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 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.
