I think you may be referring to the Mode button. If so it changes the shift point on the transmission to hold a gear a little longer theoretically giving better mileage. I think it would only be effective on slight rolling terrain. Welcome and enjoy.

Cummins and Allison calls it "Economy" Mode. We use it most of the time on the highway.
here's an interesting article: Allison Economy Mode - Engines (http://community.fmca.com/topic/1149-allison-economy-mode/)

I own a 2004 Magna built in May 2003. When I bought the Magna, Country Coach was still in business so I was able to call the Country Coach tech support line with this same question. The tech went to my build sheet to find out what the switch was for.
I was told Country Coach originally was going to use this toggle switch to turn on heated mirrors. Eventually, they elected to install automatic heated mirrors so, instead, cannibalized the switch to turn the Jake brake on and off. I turn the toggle switch on to activate the Jack brake, and then use the stage switch (with three hash marks) to set the brake to stage 1, 2 or 3 depending on how much braking is needed.
When the "M" switch is activated, the Jake brake will operate immediately when cruise control is turned off, but only when the service brake is pressed when cruise is turned on.

Rene,
The switch you describe is the compression brake switch. In the U.S. it's called the "Jake Brake" or Jacobs Brake. Next to it should be another switch with three horizontal bars of 3 different thicknesses that provide for the degree of braking when the compression brake is enabled.
To enable the compression brake the forward edge of the ((M)) switch is depressed. The amount of braking will depend on the position of the switch next to the ((M)) switch. All the way forward will deliver the maximum compression braking and all the way back the least.
When the compression brake is enabled braking will occur when the driver's foot is removed from the throttle.
There are conditions under which the compression brake will not engage, such as excessive road speed, status of the cruise control (on/off), etc. These are parameters that are set in the transmission and engine control modules.
Hope that helps.

Rene,
I also have a 2003 Magna with the 505 HP CAT. I am not completely clear on your precise question but I'll try to help. Please let me know if I miss the mark so that I can try again.
There are two switches associated with the engine brake. One is for turning the device on and off. On my coach that is located on the side console farthest forward and most outboard. The second switch is a three position switch and is located inboard of the off/on switch. This three position switch sets the brake level....Low, Medium or High.
I hope I have helped and will gladly try to answer any other questions you have with your new coach. You picked a winner.
