• Even when the vehicle ahead drives away, Early Engine Restart may not restart the engine due to limitations of the front view camera and its ability to detect the movement of the vehicle ahead.

• For more information on limitations of the front view camera, refer to Limitations of Smart ISG features.

• When ISG turns the engine off, you can restart it at any time (regardless of Early Engine Restart) by releasing the brake pedal.

• Even when you stop at a STOP, YIELD, or Roundabout sign, ISG inhibition may not deactivate the system due to limitations of the front view camera and its ability to detect traffic signs ahead.

• For more information on limitations of the front view camera, refer to Limitations of Smart ISG features.
