The steps below are how to perform an adaptive reset on the gearbox and force it to “relearn” the gearbox shift settings.
Preparing for the Reset
Safety first: Park your Mercedes-Benz on a level surface, turn off the engine, and ensure you’re in a safe location. No special tools are required for the reset process.
Step-by-Step Reset Procedure

Post-Reset Tips
After resetting the gearbox, it’s advisable to take your car for a test drive. This allows the gearbox to recalibrate itself based on your driving style. Pay attention to how the vehicle shifts between gears.
