Hyundai BSD System

The Blind Spot Detection (BSD) system in Hyundai vehicles is a crucial safety feature designed to alert drivers about vehicles in their blind spots. This system uses radar sensors mounted on the rear bumper to detect nearby vehicles and provide warnings to the driver.

How BSD Works

The BSD system activates when your Hyundai is moving forward at speeds above 20 mph. It continuously monitors the areas beside and behind your vehicle, focusing on the blind spot zones. When another vehicle enters these zones, the system triggers a visual alert on the side mirror.

Visual and Audible Alerts

  • Visual warning: An icon illuminates on the side mirror
  • Audible warning: A chime sounds if you activate your turn signal while a vehicle is detected

Checking Your BSD System

To ensure your Hyundai's BSD system is functioning correctly, follow these steps:

Visual Inspection

1. Check the rear bumper sensors for dirt, snow, or debris

2. Ensure the sensors are not damaged or obstructed

3. Clean the sensors gently with a soft cloth if necessary

System Test

1. Start your Hyundai and drive above 20 mph

2. Have a friend drive another vehicle into your blind spot

3. Observe if the BSD warning light activates on your side mirror

4. Test both left and right sides

Warning Light Check

Pay attention to any BSD system warning lights on your dashboard. If you see a "Check BSD System" message, it indicates a potential issue that requires further investigation.

Common BSD Issues

Sensor Obstruction

Dirty or blocked sensors can cause the BSD system to malfunction. Regularly clean your rear bumper, especially in adverse weather conditions.

Electrical Problems

Faulty wiring or a weak battery can interfere with the BSD system's operation. If you experience intermittent issues, have your vehicle's electrical system checked.

Software Glitches

Occasionally, the BSD system may require a software update. Visit your Hyundai dealer to ensure your vehicle has the latest software version.

Maintaining Your BSD System

To keep your BSD system in optimal condition:

  • Regularly clean the rear bumper sensors
  • Avoid placing stickers or accessories near the sensors
  • Have the system checked during routine maintenance visits
  • Address any warning messages promptly
