Rear Door Alert technology will be standard on all four-door Nissan models.

Nissan is making Rear Door Alert technology standard on a growing number of models to remind customers to check the back seat in an effort to reduce heatstroke incidents. 

Rear Door Alert, which reminds owners to check the rear seat when exiting their vehicle, monitors the rear doors to determine when they were opened and closed before and after the vehicle is in motion. 

If a rear door was used prior to a trip, but was not re-opened after the trip, the driver is reminded to check the back seat before walking away from the vehicle. 

“If you open a rear door and put something in the rear seat, Rear Door Alert will help you remember when you get to your destination that you may have forgotten it,” said Marlene Mendoza, a mechanical engineer who helped create the technology. “By drawing attention back to the vehicle while the driver is walking away, the honking alerts you to recheck the back seat in addition to visual or interior audible alerts.”
