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. 253). 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.
