Hyundai Tucson: Driving Your Vehicle / Idle Stop and Go (ISG) System
Idle Stop and Go helps reduce fuel consumption by automatically shutting down the engine, when the vehicle is at a standstill (i.e. red stop light, stop sign, and traffic jam).
ISG system is always active, when the engine is running.
Information
When the engine is automatically started by the ISG system, warning lights (e.g. ABS, ESC, ESC OFF, MDPS, and parking brake warning light) may illuminate for a few seconds if the battery voltage is low and does not indicate a malfunction with the ISG system.
