The Hyundai Sonata’s Lane Keeping Assist (LKA) system is designed to enhance your driving safety by helping you stay within your lane. Using cameras mounted near the rearview mirror, the system continuously monitors road markings and detects any unintentional lane departures.

How Lane Keeping Assist Works

When the LKA system senses that your vehicle is drifting out of its lane without a turn signal activated, it alerts you with visual and audible warnings. If you don’t respond, the system gently applies corrective steering to guide your Sonata back into the lane, reducing the risk of collisions caused by lane drifting or drowsy driving.

When to Service the Lane Keeping Assist System

  • Regular Maintenance: During routine vehicle servicing, technicians will inspect the cameras and sensors to ensure they are clean and functioning properly.
  • Warning Indicators: If the LKA warning light appears on your dashboard, schedule a diagnostic check to address potential sensor or software issues.
  • After Accidents or Repairs: Camera alignment can be affected after front-end collisions or windshield replacements, so a system recalibration may be necessary.
  • Environmental Factors: Keep the windshield area clean from dirt, snow, or debris to maintain sensor accuracy.

Maintaining the Lane Keeping Assist system ensures your Sonata continues to provide optimal safety support on every drive. Consult your Hyundai service manual or speak with a certified technician for detailed maintenance schedules and procedures.
