Solution
1. Preparation
  • Gather required tools and materials.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the negative battery terminal to ensure safety.
2. Inspect and Replace Fuel Cap
  • Remove the fuel cap and visually inspect it for any cracks or damage.
