3 Reasons Why Cadillac Parking Assist Not Working

Having trouble with your Cadillac parking assist system? You’re not alone. Many Cadillac owners have experienced issues with their parking assist not working properly. This feature is designed to make parking easier and safer by using sensors to detect objects around your vehicle and providing visual and audible alerts.

In some cases, the parking assist might not function as expected, leaving you to wonder what went wrong. Don’t worry; we’re here to help you navigate this common issue and provide some potential solutions for getting your Cadillac parking assist back on track.

What is Cadillac Parking Assist System

Automatic Parking Assist

Cadillac’s Automatic Parking Assist system is designed to help you with parallel and perpendicular parking. When activated and driving below 18 mph, the system scans for a suitable parking space. Once it detects one, you will hear a beep and receive instructions on your instrument cluster or infotainment display, telling you to stop and shift to reverse. To activate the Automatic Parking Assist, press the button on the right side of the Cadillac CUE touch screen.

Ultrasonic Sensors

The Cadillac Parking Assist system uses multiple ultrasonic sensors on your front and rear bumpers to detect the presence of obstacles. When driving at low speeds, these sensors can detect objects up to 6 feet behind your vehicle and up to 4 feet in front of your vehicle. You can turn this feature on and off using the Rear Park Assist System control or, in some vehicles, through the infotainment system.

If you are experiencing issues with your Cadillac Parking Assist System, it is essential to check that your vehicle is equipped with the “Self-Parking” feature. If the problem persists, consider troubleshooting the system and inspecting the wiring harness and connections to the sensors before replacing any components.

Remember to always drive cautiously and rely on your own judgment while parking, as the Cadillac Parking Assist system is designed to support you, not replace your driving skills.

How the System Works

Parallel and Perpendicular Parking

Cadillac’s Parking Assist system is designed to help you with both parallel and perpendicular parking. The system uses multiple ultrasonic sensors located on your front and rear bumpers to detect objects up to 6 feet behind your vehicle and up to 4 feet in front of your vehicle. To switch between parallel and perpendicular parking modes, press and hold the APA (Automatic Parking Assist) button or select the parking type from your infotainment screen.

When you engage the Parking Assist mode, the system automatically searches for a suitable parking space. As you drive slowly, it will measure the size of potential spots and indicate when it finds a suitable one. Once you’ve found the spot, follow the on-screen prompts to engage the system and control the accelerator, brakes, and transmission, while the Parking Assist system takes care of the steering.

Infotainment Screen and Alerts

Your infotainment screen plays a crucial role in the Parking Assist process. It displays information to guide you through the parking process, such as steering angles and distances from objects. As you approach an object, the Parking Assist system sends you alerts through beeps and pulses in the seat. The frequency of the beeps increases, and the pulses become stronger as you get closer to an object.

Remember to keep the Parking Assist sensors clean to ensure the system works effectively.

In summary, Cadillac’s Parking Assist system simplifies parallel and perpendicular parking by using advanced technology to automatically steer your vehicle into a parking space. Stay attentive to the alerts you receive from the infotainment screen and system beeps or pulses, and you’ll be parking like a pro in no time.

Common Issues and Malfunctions

Sensor Issues

One common issue with Cadillac’s parking assist system could be related to the sensors. If your parking assist is not working, it is essential to check if the ultrasonic sensors are clean. They might be blocked due to dirt, mud, ice, snow, or slush. When the “Park Assist Blocked” notice appears on your dashboard, your parking assist feature is no longer effective. Keeping the sensors clean can help maintain the proper functioning of the system.

Wiring and Harnesses

Another possible issue with your Cadillac’s parking assist system might involve the wiring or harnesses connected to the sensors, module, and other components. Damaged or loose wires can cause the system to malfunction or not work at all. Inspect the wires and connections, and if you find any issues, they may need to be repaired or replaced. You can consult with a professional mechanic to make sure the issue is resolved safely and effectively.

Module Malfunction

Lastly, a malfunctioning module may be the cause behind your Cadillac’s parking assist system not working. Sometimes, error codes or issues due to software can lead to malfunctions in the system. To check if the module is working correctly, you can utilize diagnostic tools or take your vehicle to a certified technician. If required, your mechanic may reprogram or reset the module, or in some cases, it might need to be replaced.

Keep in mind that these are just a few of the potential causes for a malfunction in your Cadillac’s parking assist system. Addressing these issues can help you make the most of this beneficial feature, making parking a breeze in various situations.

Troubleshooting and Resetting the Park Assist System

Checking for Obstructions

First, ensure that there are no obstructions around your Cadillac’s sensors. This includes dirt, debris, or any physical objects. Gently clean the sensors with a soft cloth and avoid using any abrasive cleaning materials as they may damage the sensors. It’s important to maintain a clear view of the sensor’s perimeter for the Park Assist system to function properly.

Resetting the System

If the Park Assist system is still not working after checking for obstructions, try resetting the system. Follow these steps to perform a reset:

  1. Turn off the ignition and wait for a few seconds.
  2. Reconnect the vehicle’s battery before turning the ignition back on.
  3. Press the Automatic Parking Assist button located on the right side of your Cadillac CUE touch screen. This action activates a beep sound, and the parking assist display appears on the touch screen, indicating that the system has been reset.
  4. Test the Park Assist System by looking for a suitable parking space. Make sure your vehicle is moving forward at a speed below 18 mph. Once the system detects a suitable parking spot, instructions will appear on your instrument cluster or the infotainment display, instructing you to stop and shift to reverse.

By following these steps, you should be able to efficiently troubleshoot and reset your Cadillac’s Park Assist system. If the issue persists or the system continues to malfunction, it is advised to consult a professional Cadillac technician for further assistance.

Conclusion

In conclusion, if your Cadillac parking assist isn’t working, first try cleaning the sensors and turning the system off and on. Remember that some Cadillacs have “Parking Assist” while others have the “Automatic Park Assist” feature, so make sure you’re aware of your car’s capabilities. Keep in mind that these systems can sometimes experience issues, but by following the mentioned steps, you can hopefully resolve any problems quickly and confidently. Stay safe and happy parking!
