Your vehicle may be equipped with the ISG system, which improves fuel economy by automatically stopping the engine when the vehicle is stopped. (For example: at a red light, at a stop sign, or in traffic jams)

The engine restarts automatically as soon as the restart conditions are met.

The ISG system is active when the engine is running.

Intelligent

When the engine restarts automatically with the ISG system, some warning lights (ABS, ESC, ESC OFF, EPS, or parking brake warning light) may come on for a few seconds.

This is caused by low battery voltage. It does not mean that the system is not functioning properly.
