Following an increase in the number of cases where parents accidentally abandon their children in the back seat of their parked cars, Nissan is introducing their Rear Door Alert system across all their four- and five-door models (sedans, pickups, SUVs) in the United States. Developed by two engineers who are also mothers at the Nissan Technical Centre North America, the aim of the system is to remind customers to check the back seat and reduce potential heatstroke cases.
The system operates on a few simple principles. It only engages if a rear door was opened prior to a trip but not re-opened after the trip. Once the vehicle is in park at the end of the trip, there will first be a notification in the instrument panel followed by a number of distinctive chirps of the horn after the driver leaves the vehicle. The Rear Door Alert system can be temporarily or permanently turned off in the cluster display.
