Idle Stop and Go (ISG)
Idle Stop & Go (ISG) system helps reduce fuel consumption by automatically stopping and restarting the engine. The engine restarts automatically when the required conditions are met.
AUTO STOP
If you engage the brake pedal and bring your vehicle to a complete stop while ISG is on, the engine automatically stops.
Bring your vehicle to a complete stop by engaging the brake pedal while the vehicle is in D (Drive) or N (Neutral).
