What a nice sis! To open the gas tank on a 2019 Chrysler Pacifica, locate the fuel door on the driver’s side rear of the vehicle and press and release the center-rear edge of the door. The fuel door should pop open. From there, you can twist the gas cap off and begin refueling the vehicle.
Don’t forget to secure your gas cap after filling up! The gas cap prevents spillage, evaporation, and contamination of the gas tank. In some Chrysler models, a Check Fuel Cap light may illuminate when the vehicle senses the fuel cap is not properly secured.
