Idle Stop and Go (ISG)
Idle Stop and Go helps reduce fuel consumption by automatically shutting down the engine, when the vehicle is at a standstill (for example, red stop light, stop sign, and traffic jam) subject to certain prerequisite conditions being satisfied as listed below.
The engine is automatically started upon satisfying the starting conditions.
ISG system is always active, when the engine is running.
When the engine is automatically started by ISG system, warning lights (for example, ABS, ESC, ESC OFF, MDPS, and parking brake warning light) may illuminate for a few seconds due to low battery voltage.
However, it does not indicate a malfunction with ISG system.
