Kia Forte: LKA operation / Warning

Kia Forte 2019-2024 (BD) Owners Manual / Driving your vehicle / Lane Keeping Assist (LKA) system / 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 of its lane because the steering torque for assistance is insufficient, the line indicator will blink.

• If all the conditions to activate LKA are not satisfied, the system will convert to Lane Departure Warning (LDW) and only warn the driver when the driver crosses the lane markers. In this scenario, the LDW system does not provide any steering inputs to 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.


If the driver still does not have their hands on the steering wheel after several seconds, the system will only warn the driver when the driver crosses the lane lines. In this scenario, the system does not provide any steering inputs to the vehicle for you. Accordingly, you must take the necessary steps to maintain control of the vehicle and keep it within the lanes.

However, once the driver has their hands on the steering wheel again, the system will again provide steering inputs if it detects the vehicle leaving the lane.



The system will be cancelled when:


The driver must be cautious in the following situations. LKA may not work properly when recognition of the lane markers is poor or limited:

• When lane and road condition are poor

- It is difficult to distinguish the lane marker from the road, such as when the lane marker is covered with dust or sand.
- It is difficult to distinguish the color of the lane marker from the road.
- There is something that looks like a lane marker.

- You drive on a steep grade or a sharp curve.
- The vehicle vibrates heavily.
- The temperature near the inside mirror is very high due to direct sun light and etc.

• When front visibility is poor

- The lens or windshield is covered by foreign materials.
