So let’s say you are driving down the road on a beautiful summer day in your Mercedes-Benz. All your windows are rolled down and the sunroof is wide open. All of a sudden: what’s that nasty smell?
Quick! Close all those windows and the sunroof. As you struggle to push five buttons, you almost cause an accident.
But wait, why are you pushing all the window and sunroof switches when you can press just one button?
How to Close the Windows and Sunroof With One Button
To close all windows and the sunroof, press and hold the recirculation button.
When you have passed the situation, press and hold the recirculation button again. All windows and the sunroof open again and return to their original positions.
This feature works on most Mercedes-Benz cars produced after 2000. Availability and operation vary by model, model year, and climate control system. Check your vehicle’s owner’s manual if the feature does not operate as described.
If It Does Not Work
If a window or the sunroof stops short or the one-touch functions have stopped working, the window and sunroof positions usually need to be relearned; see how to synchronize the windows and sunroof. If the recirculation button itself does nothing, see climate control buttons not working.
Before you buy parts, scan every control module, not just the engine. It shows the root fault behind the warning lights and tells you whether the problem is still active. See how to do a full health check.
