1. Make sure the car is in Park (P) for automatic transmissions, or in neutral (N) for manual transmissions. This is crucial for safety.
2. Push down on the parking brake lever. It's usually located on the center console between the seats. You'll feel resistance as you push it down.
3. Continue to press the pedal while lifting the lever up. The lever will need a good firm push and lift to disengage fully.
If the parking brake is stuck, try gently rocking the car back and forth while applying light pressure to the lever. If it remains stuck, you might need to investigate any potential mechanical issues.
