The Auto Stop feature in your GMC Sierra, while designed to improve fuel economy, can be annoying for some drivers. If you're tired of the engine constantly shutting off and restarting, you're in the right place. This guide explains how to permanently disable Auto Stop on your GMC Sierra, depending on your model year. Note that the exact method might vary slightly depending on your specific trim level and year.

Understanding Your GMC Sierra's Auto Stop System

Before we dive into disabling it, let's briefly understand how the Auto Stop system works. It automatically shuts off the engine when the vehicle comes to a complete stop (e.g., at a red light), saving fuel by eliminating idling. The engine restarts when you release the brake pedal. While beneficial for fuel efficiency, many find the repeated on/off cycles jarring and inconvenient.

Methods to Disable Auto Stop on Your GMC Sierra

There are generally two ways to turn off Auto Stop in your GMC Sierra: temporarily and permanently. Temporarily disabling it means you need to switch it off every time you start your vehicle. A permanent solution involves reprogramming the system (usually through the vehicle's settings menu) so it stays off by default.

Method 1: Temporarily Disabling Auto Stop

This is the simplest method, perfect if you only want to disable Auto Stop occasionally. The process usually involves:

1. Starting the Vehicle: Start your GMC Sierra.
2. Locating the Auto Stop Button: Look for a button on your dashboard, often near the climate controls. It's usually clearly labeled with an icon depicting a car with a stop sign or similar.
3. Pressing the Button: Press and hold the Auto Stop button until the indicator light turns off. This confirms that the Auto Stop system is disabled.

Remember: You'll need to repeat this process every time you start your vehicle.

Method 2: Permanently Disabling Auto Stop (May Vary by Year and Model)

Permanently disabling Auto Stop usually involves navigating your vehicle's infotainment system. The exact steps may differ slightly between model years and trim levels. Here's a general approach:

1. Start Your Vehicle: Begin with your GMC Sierra turned on.
2. Access the Settings Menu: Use your touchscreen infotainment system to navigate to the settings menu. This is usually accessed through a settings icon (often a gear icon).
3. Find Vehicle Settings: Look for a section labeled "Vehicle Settings," "Settings," or something similar.
4. Locate Auto Stop Setting: Within the vehicle settings, look for an option related to "Auto Stop," "Engine Auto Stop/Start," or similar terminology.
5. Disable Auto Stop: Select the Auto Stop setting and choose the option to disable it permanently. This might involve toggling a switch or selecting "Off."

Important Note: If you can't find the option to permanently disable Auto Stop through the infotainment system, consult your GMC Sierra's owner's manual. The manual provides specific instructions for your model year.

Troubleshooting Tips

• Check your Owner's Manual: Your owner's manual is your best resource for detailed, model-specific instructions.
• Consult a GMC Dealership: If you're having trouble finding the setting or if the above methods don't work, contact your local GMC dealership for assistance. They can provide expert guidance and potentially reprogram your vehicle's system if needed.
• Battery Considerations: Keep in mind that disabling Auto Stop might slightly reduce your fuel economy. It's also crucial to ensure your battery is in good health; frequently starting and stopping the engine can place extra strain on the battery. A weak battery may cause issues even with Auto Stop disabled.

By following these steps, you can successfully disable the Auto Stop feature in your GMC Sierra, either temporarily or permanently, to suit your driving preferences. Remember to consult your owner's manual for specific instructions tailored to your vehicle model and year.
