 When driving on a road with clear
lane lines with the dynamic radar
cruise control operating, lane lines
and preceding and surrounding
vehicles are detected using the front
camera and radar sensor, and the
steering wheel is operated to main-
tain the vehicle's lane position.
Use the this function only on highways and
expressways.
If the dynamic radar cruise control is not
operating, the function will not operate.
In situations where the lane lines are diffi-
cult to see or are not visible, such as when
in a traffic jam, support will be provided
using the path of preceding and surround-
ing vehicles.
If the system determines that the steering
wheel has not been operated for a certain
amount of time or the steering wheel is not
being firmly gripped, the driver will be
alerted and this function will be temporarily
canceled.
If the steering wheel is firmly gripped, the
function will begin operating again.
