Nissan continues to demonstrate commitment to bringing important technologies to all by now offering its clever, yet simple, Rear Door Alert (RDA)1 technology on 12 models. This is tech that potentially can help reduce risks posed by dangerous interior car temperatures.
For model year 2020, RDA is standard on the Nissan Altima, Armada, Kicks (SV and SR), LEAF, Murano, Maxima, Pathfinder, Rogue, Rogue Sport, Sentra, TITAN (King Cab and Crew Cab) and Versa (SV and SR).
Introduced with the 2018 Pathfinder SUV, Nissan’s RDA technology was developed by a pair of Nissan engineers, who are also mothers, inspired by Nissan’s “culture of innovation.” RDA was the industry’s first system to use the horn, in addition to door sensors and a message display on the center instrument panel, to remind drivers to check the back seat after the vehicle is parked.
Nissan remains committed to bringing its RDA technology to all four-door trucks, sedans and SUVs by 2022.
Last year, Nissan joined other vehicle manufacturers in a pledge to have a rear seat reminder feature in essentially all cars and trucks by model year 2025 or sooner. Under this commitment, automakers will introduce a wide range of approaches to help parents and caregivers remember to check the back seat as they leave a vehicle.
How RDA works

Once activated, the system monitors when a rear door is opened and closed before and after the vehicle is in motion. If a rear door was used before a trip but was not opened after the vehicle is parked, the system reminds the driver to check the rear seat. Once the vehicle is in park, the system will first display a notification in the instrument panel. If the driver exits the vehicle and does not open a rear door, the system progresses to distinctive chirps of the horn.
The RDA system is easy to configure and can be temporarily, or permanently, turned on through a menu in the cluster display or through a separate RDA switch, depending on the model.
