LKA (Lane-Keeping Assist) (if equipped) While driving on a freeway or motor highway that has lane markers and no sharp curves, the system recognizes the lanes using a camera located above the inside rear view mirror as a sensor to assist the driver with staying in the lane. The LKA system has two functions. 1 Lane departure warning function If the system judges that the vehicle may deviate from its lane, it alerts the driver using beeping, screen displays and a sensory warning* given via the steering wheel. *: A slight steering torque is applied for a short period of time in the direction of the center of the lane. 2 Lane keeping assist function • This function will be active when the vehicle-to-vehicle distance control mode of the cruise control is set with vehicle speed above approximately 45 mph (72 km/h) and while the lane departure warning function is active. • When the lane keeping assist function is active, a slight steering torque will be applied, to help the driver maintain the vehicle inside the lane.
