Overview
The interior camera system works with the active drive assist system to continuously observe the driver when the active drive assist system is in use.
The interior camera system observes the drivers eyes and head position to determine if the driver is attentive or distracted.
The interior camera system consists of:

Interior Camera System Operation
The interior camera system works with the active drive assist system and observes the driver when the active drive assist system is in use.
The driver status monitor camera module (also referred to as the CMR ) uses a driver status monitor camera and two infrared light emitting diodes (LEDs) to monitor the driver's eyes and head position to determine if the driver is alert or distracted.
When the module has determined the driver has not been attentive for a specific amount of time, the system alerts the driver to return attention to the road. Warning messages are displayed on the IPC message center and may include an audible warning chime.
After repeated warnings without driver response, the system applies brake pulses to alert the driver to respond. If the driver still does not respond, the system applies the brakes to slow the vehicle.
If the driver has not returned attention to the road and the active driver assist system has not reengaged, or if repeated inactivity is detected, the system remains off for the remainder of the ignition cycle.
The system may not work properly in direct sunlight, when camera and LED vision may be obscured by excessive glare.
The system may not work if the camera or infrared LEDs are obscured by any of the following;
If a system fault is detected with the interior monitor system, active driver assist system or any other vehicle system that works in conjunction with the active driver assist system, the message ACTIVE DRIVE ASSIST NOT AVAILABLE is displayed on the IPC message center.

Component Description
Driver Status Monitor Camera Module (CMR )
The interior camera system is controlled by the driver status monitor camera module (also referred to as the CMR ). The module communicates over the FD-CAN . The module is located in the instrument panel.
Driver Status Monitor Camera
The interior monitor system uses a driver status monitor camera which is used by the driver status monitor camera module to monitor the driver's eyes and head position. The camera is located in the instrument panel.
Driver Status Monitor LED
The interior monitor system has two driver status monitor infrared LEDs which are used by the driver status monitor camera module to monitor the driver's eyes and head position. The driver status monitor LEDs are part of the driver status monitor camera assembly.
