Note: Mercedes Drive Pilot is a Level 3 automated driving system first available in 2022 in select markets on S-Class and EQS. The 2020 E-Class has Driving Assistance Package features but not true Drive Pilot. This guide addresses the 2020 E-Class driver assistance system errors.
E-Class Driver Assistance Features
The 2020 E-Class offers Active Distance Assist DISTRONIC, Active Steering Assist, Active Lane Keeping Assist, and other features as part of the Driver Assistance Package. System errors indicate issues with these features.
What Causes System Errors
Driver assistance system errors result from various issues. Camera or radar sensor faults prevent proper function. Calibration loss from windshield work causes errors. Electronic control module problems interrupt coordination. Software glitches may require updates or resets.
Error Message Interpretation
Mercedes displays specific messages indicating which system has errors. Pay attention to the exact message—it identifies which features are affected and helps narrow diagnosis. General "system error" affects multiple features while specific messages point to particular components.
Diagnostic Approach
System errors require professional diagnosis. Mercedes XENTRY reads specific fault codes identifying failed components. This information guides repair—sensor replacement, calibration, or module service as needed.
