Nissan Murano: Intelligent Driver Alertness (I-DA) / Intelligent Driver Alertness 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 the ON to
the OFF position and back to the ON position.
WARNING
Failure to follow the warnings and instructions
for proper use of the I-DA
system could result in serious injury or
death.
The I–DA system is only a warning to
inform the driver of a potential lack of
driver attention or drowsiness...
Perform the following steps to enable or
disable the I–DA system.
Press the button until
“Settings”
displays in the vehicle information display
and press the OK button...
