“Traction Battery Cooler” (if equipped)

●

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. 166) 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

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. 250). 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

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

While parking

For vehicles with a solar charging system, solar charging is performed to
charge the hybrid battery (traction battery) when the necessary conditions
such as parking are met. (



P. 178)

After returning home

In order to drive the next time, charge the hybrid battery (traction battery).
Settings the charge schedule allows you to charge the hybrid battery (trac-
tion battery) at the desired time such as late at night or early in the morn-
ing. Furthermore, the charging schedule can be set to automatically
charge the hybrid battery (traction battery) every day or at the same time
on certain days. (



P. 166)

Vehicles with a solar charging system: 
When the hybrid battery (traction battery) is fully charged, charging the
battery via the solar charging system is not performed. If you are not plan-
ning on driving the vehicle for a few days, refraining from charging the
vehicle until right before you plan on using it will allow the solar charging
system to be used effectively.

switch off.

●

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



P. 166)

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 any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.

*

: 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.

■

When the charging amount sent to the hybrid battery (traction battery)
decreases

When the amount of power supplied by the charger is low or operation of the
“Traction Battery Heater”, etc., reduces the charging power sent to the hybrid
battery (traction battery), the charging amount sent to the hybrid battery (trac-
tion battery) may decrease.
