The winshield on my E300 was replaced this moning after an encounter with a thrown rock.
I'm now waiting for a system calibration. Exactly what is a system calibration?

as far as i know it's the camera(s) for lane assist etc

I had my window replaced last month for the same reason. I specifically had asked for an OEM window but when I initially arrived I was told that I would be getting an aftermarket windshield. I refused. 2 days later my insurance company called and said they didn't realize that my car had the adaptive cruise self driving cameras and they would now approve an OEM windshield. I went for a second time and they installed an OEM. Meanwhile it appears there are too many rocks on the road. I've just reached 30k on my W213 and this is my 2nd replacement windshield.

I have IR blocking windshield. I got a MB supplied winshield complete with the Carl Benz signature.
The whole process including calibration took about an hour in my garage. The company was Glass America.

I’m in the same boat with my s class. Thinking about using glass America too. Were they able to do the calibration in your garage too? There’s a glass America down the road from me and if necessary I’ll just drop the car off there

I didn't choose Glass America, State Farm did. I was pleased with their work and timelyness. Calibration was done in my garage. That part took less than 5 minutes. The work was fully paid by State Farm with zero deductible.

I wonder how they can do calibration at your garage. When I had my windshield replaced last year, I went to the dealership to get it done and State Farm paid for 80% of it. I saw that I could go to glass repair shops like Safelite but apparently you then have to bring the car to the dealership afterwards to get the calibration .

Anyway, I have another crack now but I'm dreading going through the process. Also it annoyed me that the signature is different. Not sure why MB creates so many different signature stickers.

Safelite did the calibration at their shop for my car. They said that it takes 35-65 minutes. I wasn't sure because I was on a tight schedule so I came and picked up my vehicle the next day.

Ya, I'm kinda putting off doing the crack in my window until I get some other things squared away, seems like everything I get done these days is done wrong so I doubt the windshield will be any different.

The calibration was done with a tool that was a tripod mounted screen that was positioned about 1 meter in front of the vehicle. The person also had a computer attached to the OBD port.

it is called ADAS calibration..

if your car has the lane assist/active cruise (distronic in mb parlance)/speed limit sign reading... ADAS calibration has to take place after a windshield replacement.
