To avoid issues with the fuel cap, Prius owners should:

Tighten the cap properly: Always ensure the fuel cap is tightened until it clicks after refueling.
Inspect the rubber gasket: Regularly check the rubber gasket on the fuel cap for signs of cracks o r wear. If the gasket is damaged, replace the cap.
Replace the cap every 3–5 years: Given the hot climate in Pakistan, its advisable to replace the fuel cap every few years to ensure it continues to seal properly.
Use a Toyota-recommended fuel cap: Always use an OEM o r Toyota-recommended fuel cap to ensure the proper fit and seal, preventing fuel vapor leaks.

By following these preventive measures, Prius owners can avoid the common issues associated with a faulty fuel cap, helping to maintain their car’s performance and fuel efficiency.
