Problem overview

Some Mercedes-Benz SLK350 owners report experiencing restraint system malfunctions that prevent the car from starting, often linked to battery or voltage issues that trigger warning signals. These issues can arise from a weak battery or voltage drop, which affects the vehicle's electrical system. Additionally, some owners find that a damaged battery, faulty alternator, or steering locks contribute to the SRS malfunction, requiring advanced diagnostic tools to identify and repair the underlying problems. The SRS light in the instrument cluster may also indicate airbag-related issues, while others report that problems with the seat belt buckle's electrical connection can trigger the error message. It is crucial for owners to address these concerns promptly to ensure the safety and functionality of the SLK350's restraint system, and it is advisable to have the vehicle thoroughly checked if the SRS warning light appears.
