Certain C63 AMG coupe vehicles fail to conform to Canada Motor Vehicle Safety Standard 108 Lighting System and Retroreflective Devices. These vehicles were inadvertently programmed with incorrect calibration software during vehicle assembly. As a result, the Daytime Running Lamp (DRL) system was not activated. A lack of DRL illumination could render the vehicle less visible to other motorists and to pedestrians during daylight hours, possibly resulting in a crash causing property damage and/or personal injury. Correction: Dealers will reprogram the Body Control Module.
