Advanced Driver Assist System (ADAS) and Fault Indicators

Driver Assist Systems

These are Advanced Driver Assist System (ADAS) Indicator symbols. These images will appear in a vehicle’s information display in gray scale or yellow/amber/orange. It is either the image of a car inside two straight lines as well as curved lines radiating from the front and the rear corners of the car. It looks nearly boxed in. The first symbol in yellow/amber/orange has a letter P in a box with lines radiating from it in all directions. The system in this case is being used for park assistance, with the lines in the corners illuminating if an obstacle is detected. The second light in yellow/amber/orange has an exclamation point in the center and indicates a fault in the system.

More Versions

These versions, called by the manufacturer Safety Support Indicators, is seen as a vehicle from above inside a circle, also in yellow/amber if one of the systems noted below is not functioning properly. The circle represents that the vehicle is protected all around from all sides. It may be seen in gray scale as well in the information display. The trouble may be as simple as snow and ice accumulated on or near the sonar sensors. In green, the system is up and running properly.

This version is also an outline of a car inside a circle, but appears in gray scale. The manufacturer in this case has the indicator appear when one of nearly a dozen assist system options is turned off. It is thus there to alert the driver to that fact.

This symbol is connected to a version called a Travel Assist System. It will be seen in green when activated, but will be seen in yellow/amber if a fault occurs. In this instance, the system will not engage or will be deactivated. If it is seen in gray scale, it is inactive, but not due to a fault. The system is lying in wait. When active, its primary function is maintain control of the vehicle in highway driving conditions as an advanced Adaptive Cruise Control System.

Finally, this image will be seen in green if the driver assist system is active, or in gray if the system has been interrupted.  This is not likely a fault situation, but rather due to the application of the brakes or a sensor blocked by debris. The assist system may come back on its own if the sensors clear, but will need to be re-engaged if the brakes have been applied.

Any versions of the warning light will be accompanied by information on the status of a number of systems, depending on what the vehicle is equipped with. Park Assist, Lane Departure Warning (LDW) and Lane Departure Prevention (LDP), Blind Spot Warning (BSW) and Blind Spot Intervention (BSI), Distance Control Assist (DCA), Forward Emergency Braking (FEB), and/or Predictive Forward Collision Warning (PFCW).
