“Traction Battery Cooler”

●

When  the  hybrid  battery  (traction  battery)  is  above  a  certain  temperature
and the power switch is turned off, a check screen is displayed on the multi-
information display that indicates whether “Traction Battery Cooler” is imple-
mented. Approximately 5 minutes after selecting “Yes” on this screen, sys-
tem operation becomes possible.

●

When charging starts, “Traction Battery Cooler” only operates if the hybrid
battery (traction battery) temperature is hot.

●

The  charging  indicator  is  illuminated  while  “Traction  Battery  Cooler”  is  on
standby or operating.

●

“Traction  Battery  Cooler”  is  implemented  for  a  maximum  of  approximately
30 minutes. However, when the “Departure” time is set (

P. 157) and there

is not sufficient time between the current time and the time that charging will
complete, “Traction Battery Cooler” operation time may become shorter.

●

When  there  is  a  small  amount  of  remaining  charge  in  the  hybrid  battery
(traction battery), even if the hybrid battery (traction battery) is hot, “Traction
Battery Cooler” may not be implemented.

●

When the following operations are performed while “Traction Battery Cooler”
is operating, the hybrid battery (traction battery) cooling operation stops.
• A door is opened
• The hood is opened
• The power switch is turned to any mode other than off
• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated (

multi-information display that indicates whether “Traction Battery Cooler” is
implemented. This check screen can be turned on and off in the “Meter Cus-
tomize” settings on the multi-information display (

P. 246). However, when

the check screen is set to “Off”, “Traction Battery Cooler” is no longer oper-
ates.

●

“Traction Battery Cooler” uses the power of the hybrid battery (traction bat-
tery) and external power source.
• While “Traction Battery Cooler” is operating, the amount of the remaining

charge of the hybrid battery (traction battery) increases and decreases in
a certain range, and does not increase as in normal charging.

• The operation of “Traction Battery Cooler” is recognized as charging by a

charging  equipment.  The  charging  equipment  that  calculates  the  fee
according to charging time causes a charging fee.

In  order  to  use  EV  mode,  charge
the hybrid battery (traction battery)
at home before leaving.
The charging timer function 
(

P.  157)  can  be  used  to  set  the

system  to  automatically  fully
charge  the  hybrid  battery  (traction
battery) before your desired depar-
ture time. It is also possible to set
the  air  conditioning  to  make  the
interior  in  a  comfortable  state
before your desired departure time.

At your destination

Use  a  public  charging  station  to
charge  the  hybrid  battery  (traction
battery).
If there are no charging facilities at
your destination, the hybrid battery
(traction  battery)  can  be  charged
using  the  hybrid  battery  (traction
battery) charge mode. (

P. 89)

Things to know before charging

This  vehicle  has  been  designed  to  allow  charging  from  an  external
power source using a charging cable for exclusive use with standard
household AC outlets.
However, the vehicle differs greatly from standard household electri-
cal goods in the following ways, and incorrect usage could cause fire
or electric shock, possibly leading to death or serious injury.
● The charging operation is designed to operate at 12A continuously

for the charge duration (up to 5 hours 10 minutes). (

P. 134)

● Charging can be conducted outdoors.
To charge properly, follow the procedure after reading the explanation
below. Charging is intended to be carried out by licensed drivers only
who properly understand the charging procedure.

Capacity reduction of the hybrid battery (traction battery)
The  capacity  of  the  hybrid  battery  (traction  battery)  will  decline  gradually
when  the  hybrid  battery  (traction  battery)  is  in  use.  The  rate  at  which  it
declines will differ in accordance with environmental conditions and the way
in which the vehicle is used. Observing the following can help suppress bat-
tery capacity decline.

●

Avoid parking the vehicle in areas with a high temperature under direct sun-
light when the hybrid battery (traction battery) is fully charged.

●

Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.

●

Avoid frequent driving near the top speed for EV driving. (

P. 95)

●

Leave  a  low  level  of  charge  in  the  hybrid  battery  (traction  battery)  when
leaving the vehicle undriven for a long period of time.
After  confirming  that  EV  mode  has  switched  to  HV  mode,  turn  the  power
switch off.

●

Use  the  charging  timer  function  as  much  as  possible  in  order  to  fully
charge  the  hybrid  battery  (traction  battery)  immediately  before  starting
off. (

P. 157)

Also, if the hybrid battery (traction battery) capacity reduces, the distance that
can  be  driven  in  EV  mode  decreases.  However,  vehicle  performance  does
not significantly become worse.

■

When the remaining charge of the hybrid battery (traction battery) is low
after charging
In the following situations, the remaining charge of the hybrid battery (traction
battery) after charging completes may be less than normal in order to protect
the  system  (the  EV  driving  range  after  the  battery  is  fully  charged  may  be
shorter).

*

●

Charging is carried out when the outside temperature is low or high

●

Charging  is  carried  out  immediately  after  high-load  driving  or  in  extreme
heat

When none of the above situations apply and there is a drastic drop in the
remaining charge of the hybrid battery (traction battery) after charging com-
pletes, have the vehicle inspected by your Toyota dealer.

*

: When this occurs, even if the remaining charge display of the hybrid battery

(traction battery) shows that it is fully charged, the remaining charge rapidly
decreases faster than normal.

■
