Easy Fuel “no cap” fuel system

Your fuel tank is equipped with a capless fuel filler system. This allows you to simply open the fuel filler door and insert the fuel filler nozzle into the fuel system. The capless system is self-sealing and protected against dust, dirt, water and snow/ice.
When fueling your vehicle:
1. Turn the engine off.
2. Open the fuel filler door.
3. Slowly insert the fuel filler nozzle fully into the fuel system and leave
the nozzle fully inserted until you are done pumping. Pump fuel as
normal.
4. After you are done pumping fuel, wait about five seconds before
slowly removing the fuel filler nozzle. This allows residual fuel to drain
back into the fuel tank and not spill onto the vehicle.
Note: A fuel spillage concern may occur if overfilling the fuel tank. Do not overfill the tank to the point that the fuel is able to bypass the fuel filler nozzle. The overfilled fuel may run down the drain located within the fuel filler housing and to the ground.
If the check fuel fill inlet light or CHECK FUEL FILL INLET message comes on, the fuel fill inlet may not have properly closed. The inlet may have stuck open or debris may be preventing the inlet from fully closing.
At the next opportunity, safely pull off the road, turn off the engine, open the fuel filler door and remove any visible debris from the fuel fill opening. Insert either the fuel fill nozzle or the fuel fill funnel (see Refilling with a portable fuel container for funnel location) provided with the vehicle several times to dislodge any debris and/or allow the inlet to close properly. If this action corrects the problem, the check fuel fill inlet light or CHECK FUEL FILL INLET message may not reset immediately. It may take several driving cycles for the check fuel fill inlet light or CHECK FUEL FILL INLET message to turn off. A driving cycle consists of an engine start-up (after four or more hours with the engine off) followed by city/highway driving. Continuing to drive with the check fuel fill inlet light or CHECK FUEL FILL INLET message on may cause the service engine soon lamp to turn on as well.
WARNING: The fuel system may be under pressure. If you hear a hissing sound near the fuel filler door, do not refuel until the sound stops. Otherwise, fuel may spray out, which could cause serious personal injury.
