Nissan Pathfinder: Starting and driving - Intelligent Driver Alertness (I-DA)

Basic information

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. It will not steer the vehicle or prevent loss of control.
• The I-DA system does not detect and provide an alert of the driver's lack of attention or fatigue in every situation.
• It is the driver's responsibility to:
  • stay alert,
  • drive safely,
  • keep the vehicle in the traveling lane,
  • be in control of the vehicle at all times,
  • avoid driving when tired,
  • avoid distractions (texting, etc.).

The I-DA system helps alert the driver if 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. If the system detects that driver attention is decreasing over a period of time, the system uses audible and visual warnings to suggest that the driver take a break.
