WARNING

●

If your vehicle needs to be

towed, be sure to transport the

vehicle with the front wheels

(2WD models) or four wheels

(AWD models) raised. If the

vehicle is towed with the wheels

which are connected to the

electric motor (traction motor)

contacting the ground, electric-

ity generated by the operation of

the motor may cause a fire to

occur depending on the nature

of the damage or malfunction.

(



P.507)

●

Carefully inspect the ground

under the vehicle. If leaked liq-

uid (other than water from the

air conditioning) is found on the

ground, the traction battery may

have been damaged. Leave the

vehicle as soon as possible.

In addition, contact your Toyota

dealer with regard to the leak-

age found on the ground.

Even in the event of a minor

accident, the traction battery

and surrounding parts may be

damaged. In case of an acci-

dent, have the traction battery

inspected at a Toyota dealer.

■

Traction battery

●

Your vehicle contains a sealed

lithium-ion battery.

●

Never resell, hand over or mod-

ify the traction battery. To pre-

vent accidents, traction

batteries that have been

removed from a disposed vehi-

cle are collected through your

Toyota dealer. Do not dispose of

the battery yourself. Unless the

battery is properly collected, the

following may occur, resulting in

death or serious injury:

• Do not illegally dispose of or

dump the traction battery, and it

is hazardous to the environment

or someone may touch a high

voltage part, resulting in an

electric shock.

• The traction battery is intended

to be used exclusively with your

battery electric vehicle. If the

traction battery is used outside

of your vehicle or modified in

any way, accidents such as

electric shock, heat generation,

smoke generation, an explo-

sion and electrolyte leakage

may occur. When reselling or

handing over your vehicle, the

possibility of an accident is

extremely high because the per-

son receiving the vehicle may

not be aware of the dangers

from these modifications.

●

If your vehicle is disposed of

without the traction battery hav-

ing been removed, there is a

danger of serious electric shock

if high voltage parts, cables and

their connectors are touched. In

the event that your vehicle must

be disposed of, the traction bat-

tery must be disposed of by

your Toyota dealer or a qualified

service shop. If the traction bat-

tery is not disposed of properly,

it may cause electric shock that

can result in death or serious

injury.

●

For information about traction

battery collection locations, con-

tact information, or the recycling

process, contact your Toyota

dealer.

2-1. Electric vehicle system

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

When the EV system cannot be

started due to the traction battery

being completely discharged, restart

the system after AC charging or DC

charging. When charging, it is rec-

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.

Shift position operation

battery cannot be charged. Also,
when using the air conditioning
system, etc., the traction battery
electricity is consumed.
(



P.237)

Repeated acceleration and
deceleration due to traffic con-
gestion, long waits at traffic
lights, and driving on steep
inclines will lead to poor electric-
ity consumption. In order to
avoid those situations as much
as possible, check traffic reports
before leaving. If the vehicle is
driven in traffic congestion, gen-
tly release the brake pedal to
allow the vehicle to move for-
ward slightly, avoid overuse of
the accelerator pedal. Doing so
can help minimize unnecessary
electricity consumption.

Make sure to operate the brakes
gently and a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.

Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to

release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.



Use the air conditioning only
when necessary. Doing so
can help reduce excessive
electricity consumption.

In summer: When the ambient tem-
perature is high, use the recircu-
lated air mode. Doing so will help to
reduce the burden on the air condi-
tioning system and reduce electric-
ity consumption as well.
In winter: Excessive or unneces-
sary heating should be avoided.
Also, electricity consumption can
be improved by avoiding overuse of
the heater.



When using the Remote Air
Conditioning System
(



P.409) while the AC

charging cable is connected
to the vehicle, electricity con-
sumption immediately after
starting off will be reduced
because air conditioning is
operated mainly using elec-
tricity from an external power
source.

Make sure to check the tire infla-
tion pressure frequently.

Improper tire inflation pressure
can cause poor electricity con-
sumption.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads will lead to
poor electricity consumption.
Use tires that are appropriate for
the season.

Carrying heavy luggage will lead
to poor electricity consumption.
Avoid carrying unnecessary lug-
gage.

A value for which a sufficient
level of driving performance can
be provided is estimated based
on the remaining charge of the
traction battery, the state of the
traction battery, the outside tem-
perature, etc., and is displayed
on the multi-information display.
(



P.152)

When the outside temperature
is low, the traction battery output
may be decreased, causing the
possible driving distance to be
shorter. However, this is not a
malfunction. Charge the trac-
tion battery earlier than usual.

Possible driving distance varies
significantly depending on how
the vehicle is driven, road condi-
tions, the weather, the outside
temperature, usage conditions
of electrical components and the
