Audi Rear Seat Detection
The 2025 Audi A5 features a new, integrated second-row sensor in the interior roof panel, capable of detecting small movements when the vehicle is turned OFF and locked. This new sensor system works alongside the existing mechanical detection system used in previous Audi models. Rear Occupant Detection is specifically designed to alert the driver if a rear passenger remains in the vehicle after exiting. Please note that this system serves a different purpose and operates differently from the “interior monitoring system” offered on earlier Audi vehicles.
