Subaru Forester: Idle Stop and Go (ISG) / Smart ISG

• Even if the vehicle ahead begins moving, Early Engine Restart may not restart the engine in every situation because the function depends on front-view camera detection and the camera’s ability to recognize the movement of the vehicle ahead.

• For additional details about front-view camera restrictions, refer to the Limitations of Smart ISG features section.

• When ISG has stopped the engine, you can restart it at any time, regardless of Early Engine Restart operation, by releasing the brake pedal.

• Even when the vehicle stops near a STOP, YIELD, or Roundabout sign, ISG inhibition may not always deactivate Auto Stop because the function depends on the front-view camera and its ability to clearly detect the traffic sign ahead.

• For more information about the front-view camera’s detection limits, refer to Limitations of Smart ISG features.
