Reset the roll bar on 2005 clk320?

I have a 2005 CLK 320. Roll bars deployed on a bump with the top up. Here's how to fix it: There is a reset port about 12 in below each headrest. The port is hard to find, but you can actually glimpse it with good light and/or a flashlight and some head/neck contortion. When facing forward the port is on the left side of each headrest. The port is oval in shape, about 4mm x 8mm, positioned about 10 mm forward of the support post and about 5mm to its left. Essentially, its an oval hole in black sheet metal. Mercedes mentions an allen key tool included with the car, but you can use a very long screwdriver or, preferably, a metal shishkabob barbecue skewer (by far the best) to reset the mechanism. Slide the tool (skewer, screw driver or allen key) straight down along the side of the headreast and then very carefully angle the tip forward and to the left (of car) to go into the port. Again, you can see this if you try. Push down on the spring under the port and hold down while you push down (Hard) on the headrest to its full reset position. Then remove the tool. Voila!

Before the reset, the top would not go down. After the reset, no problemo.
