How to use Rain-sensor wipers?
 

I have rain sensor on car on 2002 BMw x5. and i hav eno idea how to use it,when i push once down it wipes once. when i push once up,it slowly wipes every 7-10 seconds or so,then it has 2 other more faste rmodes. so ho wot activate rain sensor and how do i know that it working?

Just turning the wipers on starts rain sensing, if you have it. The harder it rains, the faster they will go.

it has some other shifter (they call them rain sensor sensetivity levels). what is that for? which one should i go for?

that is the first setting, in which YOU set how fast the wipers will go. Move up a notch to the "low" setting of the wiper control and that is when rain sensing will take over.

Below are 3 pages straight from the Manual on windscreen wiper operation. This should clear it up for you.

thanks

Who would have thought that the manual would have that sort of information!! :rofl: :bustingup

Rain sensor only works in pos 1 (the first setting as you put it). The dial controls the intermittent speed.

Low and Fast wipe does not use the sensor (pos 2 & 3 respectively).

how to use rotary dial #7 on pics ABove? i had it raining hard today and buttom #7 was in position I ,and it still wipers were wiping with 7 seconds interval and not faster :-( any ideas? i even put lots of water on window fast and no reaction,until 7 seconds passed and then he wiped :-(

1) Make sure the sensor area is clean. Its installed near the rear view mirror.

2) Place the wiper lever in position one. This will activate the sensor.

3) Adjust the rotary dial to the speed you like. The further you turn the dial up/forward the faster the wipes will go DEPENDENT on how much the sensor is obstructed AND vehicle speed! So, even if you have it turned all the way up/forward and splash water on the sensor it won't wipe very quickly - IF you stopped the X to splash the water. :rofl:

Hopefully, I didn't confuse you more.
