The "BAS" and "ASR" lights on a 1998 Mercedes-Benz C240 indicate issues with the Brake Assist System (BAS) and the Acceleration Slip Regulation (ASR) system. The BAS light suggests a problem with the brake assist feature, which helps enhance braking performance, while the ASR light indicates that the traction control system is engaged, potentially due to wheel slip. If these lights are illuminated, it’s advisable to have the vehicle inspected by a qualified technician to diagnose and resolve any underlying issues.
