The Super Cruise driver assistance technology may disengage or be unavailable on some 2021-2025 Escalade; 2023-2025 LYRIQ; 2024-2025 Traverse, Acadia; 2025 Enclave, CT5, ESCALADE IQ, OPTIQ, Blazer EV, Equinox EV, Silverado EV, Tahoe, Suburban, Sierra EV and Yukon models. A Driver Attention Assist Unavailable message or Can’t See Face Clearly message also may be displayed on the Driver Information Center. These conditions may be due to inoperative infrared emitter LEDs on the steering wheel. (Fig. 12)

The Driver Monitoring System is used as an input to enable or disable the Super Cruise system. It is only active when its function is requested by the K124 Image Processing Module. The system uses an infrared camera, located on the steering column, and infrared illumination, provided by IR LEDs embedded in the steering wheel, to monitor the driver and provide an estimate of the driver’s attention state to the Image Processing Module. The IR LEDs in the steering wheel may be visible as a dim red glow when the system is active.
If Super Cruise disengages or is unavailable, with the vehicle in Service Mode or the vehicle running or powered on, apply the brake, shift the vehicle to Drive, and look for the three illuminated LEDs on each side of the light bar in the steering wheel. GDS2 can be used to command on the LEDs. Go to K124 Image Processing Module 1 Processor 2 > Configuration/Reset Functions > Driver Monitoring System Illumination Command. When using this function, the LEDs will alternate from left to right.
TIP: The LEDs may not be visible to the naked eye. Using a mobile phone camera set to Live > Long Exposure may make it easier to see if both LEDs are illuminating.
If the LEDs are inoperative on one side (Fig. 13) or both sides, replace the steering wheel. Do not replace the Image Processing Module.

If all LEDs are illuminated, the steering wheel is not the cause of the Super Cruise condition. Follow the diagnostics in the appropriate Service Information to diagnose the concern.
Note: Super Cruise and other safety or driver assistance features are not a substitute for the driver’s responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road conditions at all times. Visibility, weather and road conditions may affect feature performance. Refer to the Owner’s Manual for important feature limitations and information.
