Summary of function
While driving on a road that has lane markers, this system recognizes the lane markers using a camera as a sensor to alert the driver when the vehicle deviates from its lane.
If the system judges that the vehicle may deviate from its lane, it alerts the driver using beeping and indications on the instrument cluster.

The lane departure warning will not operate for the side on which lane markers could not be recognized.
Conditions in which the function may not operate correctly
In the following conditions, the camera sensor may be unable to recognize lane markers causing the lane departure warning function to operate incorrectly.
However, this does not indicate a malfunction.

Warning indicators for lda system

As such, the driver must always assume full responsibility for understanding his/her surroundings, for operating the steering wheel to correct the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
To avoid operating the lda by mistake
Switch the lda system off using the “lda” switch when not in use.

Otherwise, the system may not function correctly and could result in an accident.
