how to show battery voltage?

I thought that I've seen this in the display before, but I can't seem to find it. I searched in the manual for "voltage" and didn't find what I'm looking for.

Can anyone describe the process to show the battery voltage?

This is for a 2013 SL63.

This is my car - might not be the same in yours....done on the COMAND display.

Displaying engine data

Press Vehicle in the main function bar.

The vehicle menu appears.

To select Driving Dynamics : turn and press the controller.

Select Engine data .

The following current data is displayed:

Engine output
Engine torque
Engine oil temperature
Transmission oil temperature (Mercedes-AMG vehicles)
On-board voltage

Interesting. I need to see if I can get this to come up on my car. Never knew this data was available. Thanks for posting.

I find the oil temperature useful. In the winter cold it takes a long time for the oil to get to the correct operating temperature. It always amuses me to see people warming their cars on winter mornings and then go speeding off down the road with only the engine at the proper temperature and the rest of the car (drivetrain, wheel bearings etc0 still at 0c.

there's no "vehicle" selection on my comand

I thought I saw it before in the screen between odometer and tach. There's an amg selection screen which shows oil temp and coolant temp, but not battery voltage.
