Hyundai i-30: Idle stop and go (ISG) system / The battery sensor deactivation

Hyundai i30 (PD) 2018-2024 Owner's Manual / Driving your vehicle / Idle stop and go (ISG) system / The battery sensor deactivation

Hyundai i30. The battery sensor deactivation

The battery sensor is deactivated, when the battery is disconnected from the negative pole for maintenance purpose.

In this case, the ISG system is limitedly operated due to the battery sensor deactivation. Thus, the driver needs to take the following procedures to reactivate the battery sensor after disconnecting the battery.

Prerequisites to reactivate the battery sensor

Keep the engine in the OFF status for 4 hours, and attempt to restart the engine 3 to 4 times for the batterysensor reactivation.

Pay extreme caution not to connect any accessories (i.e. navigation and black box) to the vehicle with the engine in the OFF status. If not, the battery sensor may not be reactivated.

Information

The ISG system may not operate in the following situations.

- There is a malfunction with the ISG system.
- The battery is weak.
- The brake vacuum pressure is low. In those cases, we recommend that you have the ISG system checked by a HYUNDAI authorised repairer.

NOTICE

Use only the genuine HYUNDAI ISG battery for replacement. If not, the ISG system may not normally operate.
Do not recharge the ISG battery with a general battery charger. If not, it may damage or explode the ISG battery.
Do not remove the battery cap. If not, the battery electrolyte, which is harmful to the human body, may leak out.

To deactivate the ISG system, ISG system malfunction
