Hyundai Sonata: Lane keeping Assist System (LKAS) / LKAS function change

The driver can change LKAS to Lane Departure Warning System (LDWS) or the LKAS mode between Standard LKA and Active LKA from the User Settings Mode on the LCD display.

Lane Departure Warning

LDWS alerts the driver with a visual and acoustic warning when the system detects the vehicle leaving the lane. In this mode, the steering wheel will not be controlled. When the vehicle’s front wheel contacts the inside edge of lane line, LKAS issues the lane departure warning.

Standard LKA

The Standard LKA mode guides the driver to help keep the vehicle within the lanes. It rarely controls the steering wheel, when the vehicle drives well inside the lanes. However, it starts to control the steering wheel, when the vehicle is about to deviate out of the lanes.

Active LKA

The active LKA mode provides more frequent steering wheel control in comparison with the Standard LKA mode. Active LKA can reduce the driver’s fatigue to assist the steering for maintaining the vehicle in the middle of the lane.
