I have a 02 clk 430, and I was wondering if its possible to make it so all my windows go down and my sunroof go back all at the same time?

Point the smart key at the car, press and hold the unlock button, the windows will go down and the roof will open. Holding the lock button does the opposite; closes the windows and the sunroof.

From inside the car, there is nothing that i know of that will open everything at once on a coupe.

"Fart mode" can unfortunately only be activated from outside the car.

Thanks guys I appreciate it. That would have been awesome had we be able to do it from inside the car.

Also, your girlfriend can do it while you drive.
