Activate or Deactivate the Start/Stop System

The Kia Rio (2011–2018) is equipped with an Idle Stop & Go (ISG) system, also known as Start/Stop. This feature shuts off the engine automatically when the car is stopped (e.g., at traffic lights) and restarts it when you press the clutch or release the brake. The system can be turned on or off using the dashboard switch.

How to Use the Start/Stop System

1. Switch the ignition ON and start the engine normally.
2. Ensure your seat belt is fastened and the driver’s door is closed.
3. With the system active, the engine will stop automatically when the car is stationary and the clutch/brake conditions are met.
4. The engine restarts automatically when you press the clutch (manual) or release the brake pedal (automatic).

How to Deactivate the System

• Press the Start/Stop OFF button located on the dashboard.
• The indicator light in the button will illuminate, showing that the system is deactivated.
• The setting resets to ON each time you restart the car, unless otherwise specified for your trim level.

When the System May Not Operate

• If the battery charge is low or recently reconnected.
• When the engine is not fully warmed up.
• If the cabin temperature is far from the set climate control setting.
• When the seat belt is unfastened or the driver’s door is open.
• If the hood is not closed properly.

Tips

• Frequent short trips can reduce battery lifespan; consider deactivating Start/Stop in heavy stop-and-go traffic.
• Ensure the main battery is healthy — a weak battery will disable the system automatically.
