Hyundai Ioniq (AE): Driving the Hybrid/Plug-in Hybrid Vehicle / Aux. Battery Saver+ (Plug-in hybrid vehicle)

The Aux. Battery Saver+ is a function that monitors the charging status of the 12 V auxiliary battery.

If the auxiliary battery level is low, the main high voltage battery charges the auxiliary battery.

Information

The Aux. Battery Saver+ function will be ON when the vehicle is delivered. If the function is not needed, you may turn it off in the Users Settings mode on the cluster. For more information, refer to the following page.

Mode

• Cycle Mode :

When the vehicle is OFF with all doors, hood and liftgate closed, the Aux. Battery Saver+ activates according to the auxiliary battery status.

• Automatic Mode :

When the Engine Start/Stop button is in the ON position with the charging connector plugged in, the function activates according to the auxiliary battery status to prevent overdischarge of the auxiliary battery.

Information

• The Aux. Battery Saver+ activates maximum of 20 minutes. If the Aux. Battery Saver+ function activates more than 10 times consecutively when 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 or if the auxiliary battery returns to normal, the function will start activating.
• 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 devises are used.

The Aux. Battery Saver+ function deactivates, when the driver cancels the system setting.

LCD Message

This message is displayed when the Aux. Battery Saver+ function has been operated while the vehicle was turned off.

However, if the LCD display message pops up frequently, we recommend that your vehicle's auxiliary battery or electric/electronic components be serviced by an authorized HYUNDAI dealer.

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.
