WARNING
Failure to observe all warnings and instructions for the proper use of the Rear Automatic Braking (RAB) system may result in serious injury or death.
Always check the side and rear mirrors and physically turn your head to look in the direction the vehicle will move before and while reversing. Never rely solely on the RAB system.
It remains the driver’s responsibility to stay alert, operate the Nissan Sentra safely, and maintain full control of the vehicle at all times.
The Rear Automatic Braking (RAB) system assists the driver when the Nissan Sentra is backing up and approaching objects located directly behind the vehicle.

The RAB system detects obstacles behind the Nissan Sentra using ultrasonic parking sensors 1 integrated into the rear bumper.
NOTE:
The sonar function can be temporarily disabled through vehicle settings; however, the Rear Automatic Braking (RAB) system itself will remain active.
