How To Reset Park Assist On The GMC Yukon

Park Assist is an incredibly helpful safety feature in modern vehicles, especially for large SUVs, such as the GMC Yukon. It uses multiple ultrasonic sensors on the front and back of the vehicle to alert drivers of nearby detected objects or vehicles while parking. However, there may be times when you need to reset this system due to a malfunction or you simply want to turn it off temporarily. In this article, we’ll guide you through how to reset the Park Assist feature on your GMC Yukon.

Understanding Park Assist and Its Features

Before diving into resetting Park Assist, let’s first understand its features and benefits:

• Safety: Front and Rear Park Assist provides alerts of nearby detected objects (up to 6 feet behind the vehicle) and helps drivers park safely.
• Visual guidance: In addition to audio alerts, some Park Assist systems provide visual guidance on the infotainment screen or dashboard display. These graphics include distance indicators and dynamic guidelines that adjust as you move your vehicle to help you accurately align it within a parking space.
• Ultrasonic sensors: Multiple sensors on both front and rear bumpers detect obstacles at low speeds (up to 4 feet in front).
• Alerts: Audio signals, such as low-pitched beeps or pulses, are emitted depending on proximity, with caution triangles displayed on the infotainment screen.

However, remember that these safety features are not substitutes for responsible driving. Always remain attentive to traffic conditions around your vehicle.

Common Reasons for Park Assist Malfunctions

Several factors can cause your GMC Yukon’s Park Assist system to malfunction.

Blocked or Dirty Sensors

Park Assist relies on ultrasonic sensors mounted on the front and rear bumpers to detect obstacles while parking. The parking assist could be blocked if these sensors become blocked or covered by dirt, mud, or debris, causing the system’s performance to be compromised. Regularly cleaning your vehicle and ensuring the unobstructed sensors will help maintain optimal functionality.

Engine Is Turned Off While Active

The Park Assist feature requires electrical power from the engine to operate correctly. Turning off your engine while the system is active may disrupt its functioning, leading to a possible malfunction. Ensure that your engine remains running during parking maneuvers when using Park Assist.

Low Car Battery

Your vehicle’s battery powers many systems, including the Park Assist feature. A low or weak battery could supply inadequate power to these systems, which can lead to malfunctions or complete failure of certain functions, such as Park Assist. Regularly inspect and maintain your car’s battery health to avoid this issue according to manufacturer recommendations.

Incorrect Steering Fluid Levels or a Blown Electric Fuse

Low power-steering fluid levels can hamper the smooth functioning of various driver-assistance features within your vehicle. Also, blown fuses can cause trouble, as they are responsible for supplying power throughout various components of the safety system as well as electronic modules controlling them, such as the Powertrain Control Module. Check both fluids and fuses periodically, topping up fluids if needed. Replacing any damaged fuses found during inspection ensures optimal working conditions for all driving aids within your GMC Yukon.

If any of these issues occur with your vehicle, consider addressing them before attempting a reset procedure.

Methods for Resetting Your GMC Yukon’s Park Assist

To reset the Park Assist system on your GMC Yukon, you can try the following steps:

1. Turn off your vehicle if it’s currently on.
2. Turn the ignition on without starting the car.
3. Press the Park Assist button, and hold it for about 10 seconds.
4. Wait for five to 10 seconds while continuing to hold the button. You should hear a beeping sound during this time.
5. Release the Park Assist button.
6. Turn the ignition off.
7. Turn the ignition back on.

Your Park Assist system should now be reset and fully functional.

Alternatively, you can try disabling and enabling the Rear Park Assist feature. Depending on your GMC Yukon model, this can be done through the vehicle setting menu or the Rear Park Assist system control. Simply turn the feature off and then back on to reset it.

Another option is to press the odometer stem. By doing so, the message indicating the need to service the Park Assist should clear, which means a successful reset.

Please note that these instructions are general guidelines, and it’s always recommended to consult your GMC Yukon manual for specific instructions tailored to your vehicle model.

If none of these methods address your issue or are unsure about performing them yourself, visit a professional mechanic specializing in GMC models for assistance.

Repair Costs for Your Yukon’s Park Assist System

In case resetting doesn’t solve your problem or there is physical damage to sensors or other components of the safety feature, repair costs can vary from $50-$250.

It’s always essential to consult with professionals before making any changes that could affect an integral safety feature, such as Park Assist, in modern vehicles like the GMC Yukon. Be sure to visit our service center for help with your service park assist on your GMC Yukon!

Safety Precautions: Don’t Rely Solely on Park Assist

While the GMC designed the Yukon Park Assist system to make parking safer and easier, it’s vital not to rely solely on this technology. The sensors may not detect all children, pedestrians, bicyclists, animals, or objects below the bumper. Always pay attention while parking or exiting your vehicle.
