Buick Encore 2020-2024 Owners Manual / Driving and Operating / Fuel / Filling the Tank (Capped Fuel Fill)

An arrow on the fuel gauge indicates which side of the vehicle the fuel door is on. See Fuel Gauge


Fuel vapors and fuel fires burn violently and can cause injury or death. Follow these guidelines to help avoid injuries to you and others:

  • Read and follow all the instructions on the fuel pump island.
  • Turn off the engine when refueling.
  • Keep sparks, flames, and smoking materials away from fuel.
  • Do not leave the fuel pump unattended.
  • Avoid using electronic devices while refueling.
  • Do not re-enter the vehicle while pumping fuel.
  • Keep children away from the fuel pump and never let children pump fuel.
  • Before touching the fill nozzle, touch a metallic object to discharge static electricity from your body.
  • Fuel can spray out if the fuel cap is opened too quickly.

    This spray can happen if the tank is nearly full, and is more likely in hot weather.

    Open the fuel cap slowly and wait for any hiss noise to stop, then unscrew the cap all the way.

Filling the Tank (Capped Fuel Fill)

To open the fuel door, push and release the rearward center edge of the door.

Turn the fuel cap counterclockwise to remove. When refueling, hang the fuel cap from the hook on the fuel door. Fully insert and latch the fill nozzle, then begin fueling.


Overfilling the fuel tank by more than three clicks of a standard fill nozzle may cause:

  • Vehicle performance issues, including engine stalling and damage to the fuel system.
  • Fuel spills.
  • Under certain conditions, fuel fires.

Be careful not to spill fuel. Wait five seconds after you have finished pumping before removing the fill nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care. Reinstall the cap by turning it clockwise until it clicks. Push the fuel door closed until it latches.


If a fire starts while you are refueling, do not remove the fill nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant.

Leave the area immediately.


If a new fuel cap is needed, get the right type of cap from your dealer. The wrong type of fuel cap may not fit properly, may turn on the malfunction indicator lamp, and could damage the fuel system and emissions system.

See Malfunction Indicator Lamp (Check Engine Light - Capless) or Malfunction Indicator Lamp (Check Engine Light - Capped)

Filling a Portable Fuel Container


Never fill a portable fuel container while it is in the vehicle. Static electricity discharge from the container can ignite the fuel vapor. You or others could be badly burned and the vehicle could be damaged. To help avoid injury to you and others:

  • Dispense fuel only into approved containers.
  •  Do not fill a container while it is inside a vehicle, in a vehicle's trunk, in a pickup bed, or on any surface other than the ground.
  • Bring the fill nozzle in contact with the inside of the fill opening before operating the nozzle.

    Maintain contact until filling is complete.

  • Keep sparks, flames, and smoking materials away from fuel.
  • Do not use electronic devices while pumping fuel.
