What does this button do? (e24) - The Unofficial BMW M5 Messageboard (m5board.com)

I just bought an e24 M635CSi

There is a button on the dash that I have no idea what it does. It is low on the dash, under the Check panel, halfway between the steering column and the driver's door. The graphic looks like a tall rectangle, with two arrows, one pointing left, and the other pointing right. I couldn't find any mention of it in the owner's manual. I feel silly not knowing what it is.

Quote from the previous owner (who bought the car NEW!)
"I never did figure it out either, but stopped feeling silly about it after a
couple of years."

Any ideas folks?

(I'm assuming anyone actually reads this forum)

just a guess....is it a circuit breaker reset switch?.......all those electronics in the 8 series......

guess the new 7 hits its own switch 20 times a day!....

external mirror adjusters?
do you have heated seat? could be a switch for those?

A picture says more than 1000 words

I can't post a picture.

The 6-Beast is in the shop!

It's not for the heated seats (It has those, but they need repair, and those controls are in the center console)

I don't think they are for the mirrors. Those controls are on the door handle.

I'll post a picture in a few days when I get the car back.

I think it could be a ligth-regulator <<< to point the beam down if
the car is loaded>>>>>>>>>>

Ferrari-BMW,

Thanks. I don't think that's it. American cars don't have that control. Rental cars I've had in Europe had that, so I know what control you are referring to.

I should have a picture of it to post by tonight...

Hmmm, I think I remenber that button from a M5 E28...two white arrows in this position: --><--

Guess what ? I think it was for the electric windows. When it is pressed and the window is closing if you try to stop the window with your hand it will stop. If it is not pressed the window won't stop and will
a) hurt your hand
b) burn the electric engine of the window.

Andy G · 15th May 2002, 09:42

Cut your hand off completely I would imagine.
Could it be the circuit breaker for the electric windows? Our E30 has this, press it and it prevents use of the electric windows, press it again, bingo, windows can be used again? (although I have seen this by the gearstick, and not where you state it is!) Clutching at straws I know.

MAYBE.......

it is a button installed by the last "good" designers of BMW cars

.....
that will AUTOMATICALLY shock some sense into CHRIS BANGLE whenever it is pressed!!! So exclusive it was only found on the FLAGSHIP BMW model of the time!!!!

So...just my advice....I would press that button as many times a day as you can!!!!!!

<----bangle

Damn, then I must have that button, too! If I find it, it will be worn in no time.

Do you want to know the secret behind Bangle? Then have a look at this

That is so funny!!!!

Thanks for sharing

Damn over-engineered cars.

The button is a lock out for ALL of the window controls on the center console.

The is also a button in the midst of the center console that locks out ONLY the back windows.

No wonder I was confused. 2 buttons that do almost exactly the same thing.
