Information Be aware of the followings when using battery conditioning mode.
• The driving distance may be reduced as energy is required to increase the battery temperature.
• If the battery temperature is low during driving or when the scheduled air conditioner/heater is activated, the battery conditioning mode is operated to improve driving performance. To ensure
driving distance the battery conditioning mode will not be operated when the battery level is too
low.
• If you set the DC charging station as your destination while using the battery conditioning mode, the battery temperature is optimized for charging and you can shorten the charging time after
you arrive and start charging.
• Battery conditioning mode is available for vehicles equipped with the battery heater.

Aux. Battery Saver+
The Aux. Battery Saver+ is a function that monitors the charging status of the 12 V battery.
If the 12 V battery level is low, the main high voltage battery charges the 12 V battery.
Information • The Aux. Battery Saver+ activates maximum of 20 minutes. If the Aux. Battery Saver+ function activates more than 10 times consecutively, in the Automatic Mode the function will stop
activating, judging that there is a problem with the auxiliary battery.
In this case, drive the vehicle for some period of time. The function will start activating if the
auxiliary battery returns to normal.
• The Aux. Battery Saver+ function cannot prevent battery discharge if the auxiliary battery is damaged, worn out, used as a power supply or unauthorized electronic devices are used.
• If the Aux. Battery Saver+ function was activated the high voltage battery level may have decreased.

WARNING
B5019903_1
When the function is activating the indicator light illuminates and high voltage electricity
flows into the vehicle. Do not touch the high voltage electric wire (orange), connector,
and all electric components and devices. This may cause electric shock and lead to
injuries. Also, do not modify your vehicle in any way. This may affect your vehicle
performance and lead to an accident.
