Limitation of Lane Following Assist malfunction

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 170 km/h, 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
