1562-2. Charging
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
■“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. 176) 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 alarm operates (if equipped) (P. 8 7 )
• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated (P. 585)
• “Charge Now” is implemented (P. 177)
• The amount of remaining charge in the hybrid battery (traction battery) is
below a certain amount
●When the power switch is turned off, a check screen is displayed on the
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. 260). 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.

■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin and a message
will be displayed on the multi-information display when the hybrid system
stops.

depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 688)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
You can replace the battery by yourself (P. 688). However, as there is a
danger that the electronic key may be damaged, it is recommended that
replacement is carried out by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
●To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
