Why Does My Adaptive Cruise Disengage?

The ‘Adaptive Cruise Control Temporarily Unavailable Warning’ is an indication that the system has been disabled, often due to an obstructed camera lens or objects detecting sensors. This issue can also be caused by a blown fuse, faulty brake module, faulty vehicle speed sensor, or bad control switch. VW’s Adaptive Cruise Control is designed to provide a seamless driving experience, but there have been reported issues that may impact its performance. Some of these issues include obstructed sensors, electrical problems, and faulty software.

If you turn on Adaptive Cruise Control and do not see the trailering icon in the DIC when trying to change your gap settings, your vehicle is not properly equipped to use Adaptive Cruise. When Adaptive Cruise Control is engaged, a green icon will appear in the instrument cluster with the following gap displayed. Conversely, when regular cruise control is engaged, a different gap is displayed.

Adaptive Cruise Control allows you to set a cruise control speed and automatically follow a detected vehicle ahead at a driver-selected following gap. If no vehicle is detected in your path, it disengages when in heavy traffic requiring stop and go or when a quick stop is approaching due to rapidly stalled traffic.

Some common problems that can keep Adaptive Cruise Control from working properly include extreme hot weather conditions with direct sunlight on the front camera, poor lighting conditions, changes in the setting sun, and moisture on the inside or outside of the vehicle. Some vehicles may have a manual warning for drivers to pay attention when driving around pedestrians, which may be why the warning appears.

In summary, the ‘Adaptive Cruise Control Temporarily Unavailable Warning’ is a common issue that can affect the performance of Adaptive Cruise Control systems. It is important to address these issues to ensure a smooth and safe driving experience.
