Fuel Filler Cap: Description and Operation
Fuel Filler Cap
The fuel fill pipe has a tethered fuel filler cap. A torque-limiting device prevents the cap from being over tightened. To install the cap, turn the cap
clockwise until you hear clicks. This indicates that the cap is correctly torqued and fully seated. A built-in device indicates that the fuel filler cap is fully
seated. A fuel filler cap that is not fully seated may cause a malfunction in the emission system.
