Here's what you should do:
1. Locate the hood release: Look under the dashboard, near the steering column on the driver's side. It might be hidden behind a small panel or cover. It could look like a small lever that pulls up, or a small tab that you pull.
2. Pull the lever or tab: Once located, pull the lever or tab firmly. You should hear a click or a sound indicating that the hood latch has been released.
3. Open the hood: Go to the front of the vehicle and carefully lift the hood. There's usually a small lip or handle near the leading edge of the hood that will help you to lift it up. You might need to apply some force at first.
If you can't find the release lever:
* Check your owner's manual: This is the definitive guide for your specific vehicle.
* Look for a small diagram: Sometimes there's a small picture near the steering wheel indicating the hood release location.
* Search online: A quick Google image search for "2002 Chevy Tracker hood release" might show you a picture of where it is located.
Remember to be gentle when opening the hood, as it might be a bit stiff. If you have trouble, ask someone for help.
