I've been browsing threads here at MBWorld and have come across some pretty cool nice to have's that are seemingly "hidden" in our e's such as the tunnel mode that will close all windows automatically by hitting the recirc button on the ac panel, even the sun roof that doesn't have one-touch close. I hadn't heard about this and was wondering if there are any others???

wow wait I gotta try that! You mean you drive w/ the windows down and the roof up, then you press the recirculation button on the AC and everything closes up?? OR do you have to hold it down for a certain amount of time?

 

Where did you read this MBZ12? Sounds too cool to be true - must try it tonight....press once and release or depress it?

 

I've also never heard of this. I must try when I get home...

 

You got my curiosity, so I searched this forum for "tunnel mode". I found info on the CLK forum, apparently, if you windows are open, along with the sunroof, you hold the "recirc" button down, some need to hold it down for, as long as, 4 seconds. The windows will raise and the sunroof will shut. If you hit the "recirc" again, the windows and roof will return to the same position. I have a '99 E320, it did not seem to work.

While I was in the car, I held down most of the buttons on the A/C panel for more than 4 secs. I turned the air on and off, but the tunnel mode did not seem to work.

But, when I held the "rest" button down, the LCD display changed, no longer did the left/right temp settings show. On the left, a "1" appeared and on the right, a two digit number appeared. As I drove around with the AC on, the right numbers appear to be the "real time" interior temperature. The numbers started at "71" and progressively came down to "67" with the AC on.

This has probably been found or posted before, but it is new to me.

Yes Rob, twice in fact. I posted the last one cos the original one was wiped out when the server went down. E-Klasse has kindly provided a list of what the codes mean - really cool! Do a search on my posts or "rest button" if you can't find it.

BTW guys, try not to burn any of the switches by holding them on for too long

 

Sorry I didn't clarify this....but yes, apparently on some models, including E, you can hit the recirc button and press for 4 seconds and everything closes up. This may or may not work with your car but apparently you can take it to the dealer to have this activated. I'll copy this link when I get a chance.

whitey - Thanks for the clarification. The server down issue makes sense to me now. I tried to find previous posts, but they no longer exist

 

Of course it exists - try naving between pages (there's more than one here!). I think I titled it" "REST button again"

If I find it before u, I'll post a link.

 

Here you go:

REST BUTTON LINK

 

".....Well, I did some experimenting today and I got my sunroof to work in tunnel mode. Hopefully you guys will not have as much of a problem getting your dealer to turn this on, because it is something that should be enabled anyway.

Here are the instructions for the DAS computer that they have at the dealer:

Go to Control Units --> Body --> Overhead Control Panel(OCP) --> Control Unit Adaptations --> Read coding & change if necessary --> Modular Roof

On the modular roof screen, set "Automatic closing function" to "Active" and that should do it.

Good Luck....."

Wonder if it will work with E's.....
