RVM system will alert you with beep sound only if you operate turn signal to warn you to not switch lane because vehicles approaching from behind.

If you remain on current lane and other vehicles approaching from behind then rvm system only alert you with warning light on your side mirror.

I most of the time will ignore the warning light or just don't notice it. If went to cilok here and there during heavy traffic then this system very useful.

SCBS only work if your car at speed of 4-30 km/h. Only work if sensor which is at the top centre of windscreen detects any obstruction in front. If you park your car and nothing in front like wall or high gate then the system will not apply. I personally never try. Some people on Youtube had tested with dummy wall (big polisterin) and you can check over there. Not suggesting to test with real wall. Because this system is mean for real emergency break only. Hehe

LDW for me is very distracting unless u got drunk while driving then this system very useful lol
