@Tai newbie,
Can you please elaborate on first three.?
LDW - When ever the car is sliding into the next lane with out the indicator turned on, it alerts the driver with a beep and a flashing light in the headsup display.
FCW - If the the distance between the car in front of you and you is less than the specified threshold, and you are driving at a speed greated than 30 miles per hr, it alerts the driver with a beep and flashing light in the HUD.
Here is an image for the lane change camera.
