Use of the recommended fuel is an important part of the proper maintenance of your vehicle. To help keep your tank and fuel cell system clean and maintain optimum vehicle performance, use only fueling stations approved by GM.
Notice: Your vehicle was not designed for receiving fuels other than compressed hydrogen. Fueling nozzles other than those for compressed hydrogen can cause damage to metal, plastic, and rubber parts.
Hydrogen Specifications
Use only hydrogen meeting specification J2719.
Fueling Station Pressure Levels
The vehicle is designed for 10,000 psi (70 MPa) compressed hydrogen.
If no 10,000 psi (70 MPa) compressed hydrogen fueling dispenser is available, a dispenser with a lower pressure level, such as 5,000 psi (35 MPa), can also be connected to your vehicle. In the case of a low pressure fill, the vehicle hydrogen tank only gets filled to the pressure level used for the fueling.
