Nissan Maxima Owners Manual: Driver Attention Alert system operation
If the system detects driver fatigue 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 37 mph (60 km/h).
The system continuously monitors driver attention and can provide multiple warnings per trip.
The system resets and starts reassessing driving style and steering behavior when the ignition switch is cycled from on to off and back on.
