Kia Optima DL3: LKA operation / Warning

If the vehicle leaves a lane, the lane marker you cross will blink on the LCD display.

If the vehicle moves out its lane because steering torque for assistance is not enough, the line indicator will blink.

  • If all the conditions to activate LKA is not satisfied, the system will convert to LDW and warn the driver only when the driver crosses the lane markers. In this scenario, the LDW system does not provide any steering inputs into the vehicle for you. Accordingly, you must take the necessary steps to maintain control of the vehicle and keep it within the lanes.

If the driver takes hands off the steering wheel for several seconds while the LKA is activated, the system will warn the driver.

WARNING

  • If you hold the steering wheel lightly, the system may generate a hands off warning because the Lane Keeping Assist may not detect the presence of the driver's hands on the steering wheel.
  • If you hold the steering wheel lightly, the system would generate hands off warning because LKA can treat the situation as you do not grab the wheel.

If the driver still does not have their hands on the steering wheel after several seconds, the system will not control the steering wheel and warn the driver only when the driver crosses the lane markers.

However, if the driver has their hands on the steering wheel again, the system will start controlling the steering wheel.
