Why don't Mercedes-Benz mirrors retract when locking the doors?
2 Answers
Mercedes-Benz mirrors not retracting when locking doors could be due to a dead battery or manual folding after setting automatic folding. Here are the specific reasons: Dead battery: In this case, the exterior mirrors must be reset to function normally. The specific reset method is to manually operate the folding button. There are three buttons on the door, press the middle one. Manual operation after setting: If "fold mirrors when locking" is set but manually folded, the exterior mirrors will not automatically unfold the next time the car is unlocked. You need to enter the car and press the button on the door to manually unfold the exterior mirrors.
I encountered an issue with my Mercedes where the mirrors didn't retract after locking the doors. It happened suddenly, so first I checked if the folding function was accidentally turned off in the settings—some owners might have unknowingly disabled it via the button on the center console. Next, I inspected the fuses, as a blown fuse would need replacement; these are located in the fuse box under the hood. The problem could also stem from the door lock sensor, where dust or damage might prevent signal transmission. It's best to start by cleaning the door frame area or restarting the vehicle, then trying to lock it a few times to reset the system. If that doesn't work, a professional should check the electronic control unit, given the complexity of Mercedes' electronic systems. This issue isn't uncommon, and neglecting it could compromise parking safety or accelerate part wear. I recommend regularly checking your settings to avoid such hassles.
