Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear protective gloves and eyewear.

2. Remove the Gas Cap

Twist the gas cap counterclockwise to remove it from the filler neck.
Inspect the cap for any signs of wear or damage.

3. Inspect and Clean

Inspect: Look for cracks or wear on the rubber seal of the gas cap. If damaged, replacement is necessary.
Clean: Use a clean cloth to wipe the sealing surface of the gas cap and the filler neck to remove any dirt or debris. Ensure the area is dry and free from contaminants.

4. Replace the Gas Cap (if necessary)

If the gas cap is damaged, install a new gas cap:
- Ensure the new gas cap is compatible with the Volvo XC60 (OEM recommended).
- Align the cap with the filler neck and twist it clockwise until it clicks securely in place.

5. Reset Check Engine Light

If the check engine light remains on after replacing the gas cap, use the OBD-II scanner to clear the error codes.
Turn the ignition on without starting the engine and follow the scanner's instructions to reset.
