System limits
Personal responsibility
The system cannot serve as a substitute for the driver's personal judgment of the course of the road and the traffic situation.
In the event of a warning, do not jerk the steering wheel, as you may lose control of the vehicle.
The system may not be fully functional in the following situations:
▷ In heavy fog, rain or snowfall.
▷ In the event of worn, poorly visible, merging, diverging, or multiple lane markings such as in construction areas.
▷ When lane markings are covered in snow, ice, dirt or water.
▷ In tight curves or on narrow lanes.
▷ When the lane markings are covered by objects.
▷ When driving very close to the vehicle in front of you.
▷ When driving toward bright lights.
▷ When the windshield behind the interior rearview mirror is fogged over, dirty or covered with stickers, etc.
▷ During the calibration process of the camera immediately after vehicle shipment.
