Nissan LEAF 2023 Owners Manual
9.19.2. System operation
If the system detects that driver fatigue increases or that driver attention is decreasing, the message [Take a break?] appears in the Vehicle Information Display and a chime sounds when the vehicle is driven at speeds above 60 km/h (37 MPH).
The system continuously monitors driver attention and can provide multiple warnings per trip.
The system resets and starts reassessing driving style and steering behaviour when the power switch is turned off and then placed back in the ON position.
