■Charging the traction battery
Be sure to maintain the traction bat-
tery charge level suitable for your
driving needs.
If the traction battery fully dis-
charges, the vehicle cannot be
driven at all. When the battery
becomes low, charge it as soon as
possible.
■If the traction battery becomes
low
●If the traction battery becomes
low, the traction battery charge
warning light comes on or flashes
and a message will be displayed
on the multi-information display.
(  P.515)
●If the traction batte ry is completely
discharged, the EV system cannot
be started and dri ving will not be
possible. When the traction bat-
tery becomes low, charge it as
soon as possible.
■Sounds and vibrations specific
to an battery electric vehicle
Because there is no engine sound
or vibration, it is easy to mistake the
battery electric vehi cle for being off
when it is actually still running, as
indicated by the “READY” indicator
being illuminated. F or safety, make
sure to always shift the shift position
to P and apply the parking brake
when parked.
Before and after the EV system is
started, the following sounds and
vibrations may occur. However,
these sounds and/o r vibrations are
not signs of malfunctions:
●The brake system operation
sound may be heard from the
front of the vehicle when the
driver’s door is opened.
●Motor sounds may be heard from
the motor compartment or lug-
gage compartment.
●Electrical relay sounds may be
heard from the motor compart-
ment when the EV system starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the traction b
attery in the fol-
lowing situations:
• When the EV system is started or stopped
• When charging starts or com-
pletes
• When the vehicle is driven the first time after the traction battery has
been charged using DC charging
●Sounds may be heard due to
regenerative braking when the
brake pedal is depressed or as
the accelerator pedal is released.
●Cooling fan operating sounds
from the radiator.
●The operation sound of the air
conditioning system (air condition-
ing compressor, blower motor).
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
A sound which changes in
accordance with the driving
speed, will be played in order to
warn people nearby of the vehi-
cle’s approach. This sound may
be heard inside the vehicle. The
sound will stop when the vehicle
speed exceeds approximately
23 mph (37 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting System may be dif-
ficult for surrounding people to hear.
Acoustic Vehicle Alerting
System

802-1. Electric vehicle system
Owners Manual_USA_M42C01_en
When a certain level of impact is
detected by the impact sensors,
the emergency shut off system turns off the EV system and
blocks the high voltage current.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the EV sys-
tem, contact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the EV system or an
improper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. (
P.140, 522)
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The EV system may not start.
In that case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
■When the traction battery is
completely discharged

WARNING
■Caution while driving
●Pay special attention to the area
around the vehicle. Because
there is no engine noise, pedes-
trians, people riding bicycles or
other people and vehicles in the
area may not be aware of the
vehicle starting off or approach-
ing them, so take extra care
while driving. Therefore, take
extra care while driving even if
the Acoustic Vehicle Alerting
System is active.
●If the vehicle under floor area
receives strong shock or impact
while driving, stop the vehicle in
a safe place and check around
the bottom of the vehicle. If
there is damage to the traction
battery or liquid leakage, it may
lead to a vehicle fire, etc. Do not
touch the vehicle and immedi-
ately contact your Toyota dealer.
Even if no damage can be seen
under the floor, the traction bat-
tery may be damaged. If the
vehicle received an impact
under the floor, have the traction
battery inspected at a Toyota
dealer.
■Modifications
Do not make modifications that
lower the height of the vehicle.
The traction battery in the under
floor area may come into contact
with the ground when the height
of vehicle is lowered. If the trac-
tion battery is damaged, a vehicle
fire may occur, possibly resulting
in death or serious injury.

cle driving tips
Unlike the conventional
vehicles, the electricity con-
sumption efficiency of bat-
tery electric vehicles will
decline if they continue
driving on highways (or
freeways) or at high aver-
age speeds, causing the
possible driving distance to
reduce. Therefore, if the
remaining charge of the
traction battery is low, avoid
relying on the displayed
possible driving distance
too much as well as driving
on highways (or freeways).
Driving the vehicle at mod-
erate speeds, the traction
battery’s electricity con-
sumption can be controlled.
The following driving tips
will contribute to reduction
in the battery consumption
and increase in the driving
range.
