Hazard

The multi-purpose camera in the lane departure prevention support system (Active Lane Keeping Assist) has improper dynamic tire radius settings for vehicle speed calculation, resulting in inaccurate speed computation. Consequently, when the vehicle drifts from its lane during high-speed driving, no warning display or brake control intervention occurs.
