Highway assist quick guide
Highway assist, like adaptive cruise control, helps you maintain a set speed and interval between your car and the vehicle in front of you. Highway assist also includes lane centering control, and can even automatically change lanes for you if auto lane change assist is activated. The speed range of the function is 0–130 km/h. For more information, see Highway assist.
Note: When highway assist is activated or deactivated, the message LCC activated or LCC canceled (referring to the lane centering control) appears in the notification area.
An arrow appears on either side of the highway assist symbol 
in the driver display and the head-up display when automatic lane change assist is available, and safe to initiate, for that lane. Initiate an automatic lane change by activating the direction indicator lights towards the side you want to change lane to.
