Nissan LEAF 2023 Owners Manual
3.8.2. Approaching Vehicle Sound for Pedestrians (VSP) system
The Approaching Vehicle Sound for Pedestrians (VSP) system uses sound to alert pedestrians of the presence of the vehicle when it is driven at a low speed.
When the vehicle starts to move, it produces a sound.
The sound stops when the vehicle speed exceeds approximately 30 km/h (19 MPH).
The sound (re-)starts when the vehicle speed drops below approximately 25 km/h (16 MPH).
The sound stops when the vehicle stops.
Drivers must use the VSP (especially when reversing the vehicle) with due care/consideration and ensure that they comply with the laws of the jurisdiction in which they operate the VSP.
The VSP system should only be turned off in certain very unusual situations, where the presence of pedestrians is very unlikely, such as in a traffic jam on a highway. The VSP system should never be turned off if there is a chance pedestrians will be present.
If the vehicle is driven with the VSP system switched off, pedestrians may not notice the oncoming vehicle, which may cause an accident resulting in serious personal injury or death.
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 of the vehicle.
If the sound cannot be heard when the VSP system is ON (VSP OFF indicator not illuminated), immediately contact a knowledgeable LEAF repairer such as a NISSAN certified electric vehicle dealer for inspection.
If you wish to increase the volume of the VSP system, contact a knowledgeable LEAF repairer such as a NISSAN certified electric vehicle dealer. (It is not possible to lower the volume.)
