Rear Parking Sensor

[Varero]

For Merc E Class, the rear parking sensors on the left n right extreme side, does it beep when it sense objects? The rear back sensors n front sensors ( both front n side) all beep when they sense object. But mine, the rear side sensors doesn't beep. Is it normal ?

do you model come with indicator?

It only beeps when the LED shows the red bar. e.g. when very close.

 

Otherwise, it is a visual indicator.

My model has back indicator inside the top of rear window. It only beeps at the rear bumper when object is near but not at the 2 rear sides.

if your car come with indicator, it will only "Beep" in red zone. Another word your car is normal.

My e250 side sensors beeps and gives me a shock when a bike squeezes past me from left or right. But as he is so fast, I hear a beep and when I look around, see nothing unusual and I am left scratching my head as to cause of beep. Then I realise it was a biker.
