2.12. Approaching Vehicle Sound for Pedestrians (VSP) system
The Approaching Vehicle Sound for Pedestrians (VSP) system is a function that uses sound to help alert pedestrians of the presence of the vehicle when it is being driven at a low speed.
The VSP sounds when the READY to drive indicator light is illuminated under the following conditions:
When the vehicle speed is within 30 km/h (19 MPH) when starting.
When the vehicle speed is less than 25 km/h (16 MPH) while decelerating.
When the shift position is in the R (Reverse) position.
The sound stops when the vehicle stops.
If the system malfunction occurs, the VSP warning light 
in the meter illuminates. If the VSP warning light illuminates, have the VSP system checked by a NISSAN dealer or qualified workshop immediately.
If the sound from the VSP system is not heard while driving, stop the vehicle in a safe and quiet location. Open a window, and then place the vehicle in the R (Reverse) position with the brake pedal firmly depressed. Check that the operating sound can be heard from the front side of the vehicle. If the sound from the VSP system is not heard, contact a NISSAN dealer or qualified workshop.
The VSP also sounds when all of the following conditions are met, in order to remind you to place the power switch in the “OFF” position.
When the shift position is in the "P" (Park) position.
When the READY to drive indicator light illuminates.
When the driver's seat belt is not fastened.
When any door (except the back door) is opened.
If you wish to increase the volume of the VSP system, contact a NISSAN dealer or qualified workshop. (It is not possible to lower the volume.)
