Star Diagnostic How To DIY with lots o pics
On my C4 Xentry, just as in previous posts, you have to activate it in Variantenkodierung Werkseinstellunhen.
But you have to reset the cluster by hitting F1 till you get to
- Actuations
- Complete index of actuations
-Steuergeraet Resetten ( PowerON-Modus) (FN_Reset_SG_Power_ON)
Hit F3 and confirm again with F3.
your cluster will reset. It takes time as the clock goes to 12 and back to actual time. So wait for this to finish.

I actually think this is one of the more useful things to display in the cluster! When I did it a couple years ago I still find myself sitting on this screen the most. I'd much rather want to know fuel remaining than looking at the bar indicator in the cluster.

All the best!
So far, I believe that this is part of the solution:
-Information & Communication
-Instrument cluster
-Diagnose to plant specifications
-Control unit Adaptations
-Varian coding
-Read coding and change if necessary
-Variantenkodierung Werkseinstellungen
And I tried to set:
Vorrzeitiger abbruch gurtwarnung
To
Vorzeitig. Abbruch
Now, do I reset something after this codes?
There is also right below the first line
Gurtwarnung
What should this parameter be set to? Currently it's set to ab Motorstart
Input is appreciated!

developper mode
special functions (you need to have a pass if its not a quality system)
>disable seat belt warning for gulf states)
should add this too. The is called HSVL and I saw that in xentry somewhere...
More updates. There is in command REAR SCREEN coding so set that to present.
Quick tests > command or audio> F3 > control unit Adaptations > read coding and change if necessary > rear screen
Hope this is the solution. If not pm the member that offered help privately

In instrument cluster, go to :
diagnosis to plant specifications> control unit >Adaptations then variant coding >Variantenkodierung Werkseinstellungen
you have to switch 3 things:
VORZEITIGER ABBRUCH GURTWARNUNG select vorzeit.Abbruch
Gurtwarnung select abKI15G
NCAP Gurtwarnung select nach Konfiguration
This works on my W211
Oh, you need to reset the Instrument Cluster for the changes to take effect. I posted this not long ago
in Instrument cluster, go to actuation, complete index, Steurgeraet Resetten ...

And set:
DEFROST Logic to alt
No need to reset anything.
I also wanted to see the fan speed bars in AUTO mode. While you are there,
Set Grundeinstellung:Geblasebalken im Auto-Modus to an (Serie)
