My 05 built in July has a rest button but won't do anything. Do you need to be stopped with engine off? Keys in ignition? What position?

I got to the menu with either: key in the on position or the car running and then held the "rest" button in.

I was playing around with this yesterday...

To scroll up & down through the list you use the Driver's Side Temperature adjustment buttons. If you press the PASSENGER Side Temp adjustment buttons the values CHANGE and a small vertical bar "|" appears in the center of the display indicating that the value has been modified.

I am not sure why this behaviour is there, but the values can be modified on the display. I am just not sure if they can somehow be saved????? Why would they make them modifiable if they are supposed to be read-only?

I found the same thing.
If they are sensor outputs I can't see that you can permanently alter them - unless you're adjusting the zero point for that sensor.

Was that a July'05 build? Mine is a Feb '05 with no rest button. Part of the trade-offs I guess.

Sorry I was wrong, July 04, the first month of 05 production.

Anyone find this out? Wonder what 41 thru 99 are for. Quite a handy little hidden feature.

I have a W210 E55 with a rest button. Does this apply?

Not sure, try it...just hold the 'rest' button down for about 5 secs with ignition on or engine on.

Found this and translated it with babelfish so its a bit ???

Same here. I tried to hold on to the "OFF" button...nada.
