Once you locate it, simply pull or push the tab or lever to release the trunk latch. This will allow you to open the trunk manually. It’s important to note that this method may vary slightly depending on the model year of your Mazda 3.

Consulting your vehicle’s manual will provide you with specific instructions for your particular model.
