Lane Changing
ACC will not detect a vehicle until it is completely in the lane in which you are traveling. In the illustration shown, ACC has not yet detected the vehicle changing lanes and it may not detect the vehicle until it’s too late for the ACC system to take action. ACC will not detect a vehicle until it is completely in the lane. There will not be sufficient distance to the lane-changing vehicle. Always be attentive and ready to apply the brakes if necessary.
