Fuel Filler Cap: Description and Operation
The fuel fill pipe has a tethered quarter-turn type 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 fuel filler cap that is not fully seated may
cause a malfunction in the emission system.
