9.21. Intelligent Driver Alertness
Failure to follow the warnings and instructions for proper use of the Intelligent Driver Alertness system could result in serious injury or death.
The Intelligent Driver Alertness 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 Intelligent Driver Alertness 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 travelling lane.
Be in control of the vehicle at all times.
Avoid driving when tired.
Avoid distractions (texting, etc.).
The Intelligent Driver Alertness 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.
