1. Locate the release lever: This is usually found in the cargo area, either on the side of the cargo area or under the cargo floor. It might be a small handle or a crank. Look for a label or marking that indicates its purpose.
2. Engage the release: Pull the lever or crank. You may hear a click or whirring sound as the mechanism disengages.
3. Lower the spare tire: Once the release is engaged, the spare tire should slowly lower itself. You may need to gently assist it by pushing or pulling it downwards. It's usually on a cable mechanism, so don't force it.
4. Secure the spare: Once the spare is fully lowered, you should be able to easily access it for installation.
If you can't find the release:
* Consult your owner's manual: This is the most reliable source of information for your specific model year and trim level. It will show you exactly where the release is and how to use it.
* Search online: A quick search for "[your GMC Envoy year] spare tire release" will likely yield images and videos demonstrating the process.
* Check under the cargo floor: Many Envoys have the mechanism hidden under a panel or cover in the cargo area. You might need to remove some carpeting or a panel to access it.
Important Note: If the spare tire doesn't lower after you've tried these steps, there might be a problem with the cable, winch, or the release mechanism itself. Avoid forcing it, as you could damage the system. In this case, it's best to seek professional help from a mechanic or a tire shop.
