Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
With the Sentra stopped, use the steering-wheel controls to open Settings in the vehicle information display.
- 02
Open Vehicle Settings, select Rear Door Alert and choose Horn & Alert, Alert Only or OFF.
- 03
To use the reminder, open and close a rear door before driving; the system records that door event.
- 04
After the trip, shift to Park and read the display prompt; dismiss it for that stop or follow the prompt if you want to disable the reminder.
- 05
If Horn & Alert is selected, close the vehicle and listen for the exterior horn reminder after leaving.
Important limits
- Rear Door Alert detects rear-door opening and closing events; it does not detect people, animals or objects in the rear seat.
- Always inspect the rear seat before leaving the vehicle, even if no alert appears.
- The reminder logic depends on a rear door being opened and closed around the beginning of a trip and may not activate for every door-use pattern.
Quick checks.
- ✓If no reminder appears, confirm Rear Door Alert is not set to OFF and repeat a trip after opening and closing a rear door.
- ✓If the display alert appears but the horn does not, select Horn & Alert rather than Alert Only.
- ✓If the setting does not remain selected, cycle the ignition and recheck Vehicle Settings; have the display system inspected if the menu is unavailable.
