Lane Following Assist malfunction and limitations

Lane Following Assist malfunction

A: Check LFA (Lane Following Assist) system

The warning message popped up (turned off after a certain period of time) means a problem with Lane Following Assist. In this case, have the system checked by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner.

CAUTION

  • It is the driver's responsibility to operate the steering wheel while driving.

  • With Lane Following Assist on, the driver can steer the vehicle by operating the wheel on his own.

  • We recommend that the driver turns off Lane Following Assist and operates the steering wheel by himself in the following cases

    • Bad weather

    • Bad road conditions

    • When frequent operation of the steering wheel is required

    • When towing other vehicle or trailers

  • The steering wheel can feel heavy or light if Lane Following Assist is assisting the steering.

Limitations of Lane Following Assist

  • If the driver turns on the turn signal light or the emergency warning light to change the lane

    • Operate the turn signal light switch before changing the lane

    • If you change the lane without operating the turn signal lights, steering reaction force of the wheel may occur.

  • Once Lane Following Assist is turned on or the lane is changed, the vehicle should be in the center of the road to switch to the steering assist mode. If the driver keeps driving along the lane, Lane Following Assist will not assist the steering.

  • When the ESC or VSM is activated, the function does not assist steering.

  • When driving on a curved road at a high speed, steering assist mode may not work.

  • When driving at a speed faster than 150 km/h (90 mph), steering assist mode may not work.

  • When sudden steering is made, the function could be temporarily deactivated.

  • If you change the lane in a hurry, the function does not assist the steering.

  • If the vehicle suddenly stops, it does not assist the steering.

  • If the lane is too narrow or too wide, steering is not assisted.

  • If the function is not able to recognize a vehicle in front and either of the lanes is not recognized, the steering is not assisted

  • If the radius is too small for the curve

Cautions for the driver

If the lane recognition is difficult or limited for Lane Following Assist as shown below, the driver may need to be careful because it may not operate or may cause unnecessary operation.
