Clean the sensors on the front of the car, they get blocked by road salt and other detritus. They can also be blocked by heavy rain/spray

I had a few warnings on my car (2021 GLC) when I first got the car, these stopped when I gave it a decent charge with the CTEK, the car was a very low mileage purchase having completed only 2300 miles on collection as it was a lockdown car.

I also had another warning recently when I had it serviced and they had turned the light switch off from auto and I sat in the car for around 40 mins waiting with radio on and did not notice the lights were also on.

Mercedes cars or quite a few it seems like to have a healthy charge.
