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.

If there are lane markers on only one side of the vehicles
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.
When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
Warning indicators for lda system
Warning indicators are used to indicate a system malfunction or to inform the driver of the need for caution while driving.
Caution
Before using the lda system
Do not rely solely on the lda system. The lda system does not drive the vehicle automatically, nor does it reduce the amount of care you need to take. 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.
Situations unsuitable for lda system
Do not use lda system in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
Notice
To prevent damage to or incorrect operation of the lda system
Camera sensor
Observe the following to ensure that the lda system functions correctly.
Performance could be affected if the windshield is dirty, or if raindrops, condensation or ice are adhering to the windshield.
When it is cold, using the heater with air blowing to the feet may allow the upper part of the windshield to fog up. This will have a negative effect on the images.
