FUNCTION DESCRIPTION
-
The Intelligent Drive Alertness (I-DA) is controlled by the ADAS control unit control unit.
-
ON/OFF of the Intelligent Drive Alertness (I-DA) is performed by using the combination meter.
-
Intelligent Drive Alertness system helps alert the driver when the system detects a lack of attention or driving fatigue.
-
The system monitors driving style and steering behavior over a period of time, and it detects changes from the normal pattern.
-
When the system detects that driver attention is decreasing over a period of time, the system uses an audible and visual warning to suggest that the driver take a break.
OPERATION DESCRIPTION
-
When the system detects that driver fatigue or that driver attention is decreasing, the message “Take a break?” appears in the Nissan Murano 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 behavior when the ignition switch is cycled from on to off and back on.
Operation Condition
-
Intelligent Drive Alertness (I-DA): ON
-
Vehicle speed approximately 60 km/h (37 MPH) or more
NOTE:
-
Intelligent Drive Alertness (I-DA) system ON/OFF can be set on the combination meter.
-
When the ignition switch OFF, the system is reset.
-
The Intelligent Drive Alertness (I-DA) system may not function properly, depending on the situation. Refer to Precautions for Intelligent Drive Alertness.
