Improves fuel economy by automatically eliminating idling. 

Idle Stop & Go System

The ISG system is to reduce the 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).  

To stop the engine in idle stop mode 

  1. Decrease the vehicle speed to 0 km/h. 
  2. Depress the brake pedal with the shift lever in D (Drive) or N (Neutral). The auto stop indicator illuminates in green on the instrument cluster, when the engine stops.
  3. The engine is automatically restarted when you release the brake pedal.
