I was trying to make this work. Now I know that you have to double-click and hold. Nice tip.It is a nice feature and it works too for opening the windows and pano roof (clicking the open button and clicking again and hold).
For those without Keyless Go, must have the fob close to and pointing at the drivers side door handle and those with Keyless Go you just need to be in the proximity on any side of the car.
One thing to add, for those with Keyless Go, lock the car (with a touch on any door handle) and then proceed to place only one finger on the square indent on the door handle. Hold till all the windows and pano roof closes. To open do the same. No need to find and fiddle with the fob.It is a nice feature and it works too for opening the windows and pano roof (clicking the open button and clicking again and hold).
