How to Disable Seat Belt Warning in Mercedes with DTS Monaco

The seat belt warning system in Mercedes-Benz vehicles can be an annoyance for some drivers, especially when driving in areas where seat belt laws differ or when working on a vehicle that does not require this feature. Using DTS Monaco, a powerful engineering software for Mercedes-Benz, you can easily disable seat belt warning and customize your vehicle’s coding settings.

This guide will walk you through the process step by step to ensure a smooth and error-free procedure.

• Laptop with DTS Monaco installed – A fully configured version with access to vehicle projects.
• Mercedes-Benz-compatible diagnostic interface – Such as C4, C5, or C6 multiplexer.
• OBD-II connection cable – To establish a connection between the laptop and the vehicle.
• Stable power supply – To prevent any disruptions during the coding process.
