* Check the vehicle's sticker: Look for a sticker on the driver's side doorjamb or the glove compartment. This sticker will list the GVWR along with other important weight information.
* Consult the owner's manual: The owner's manual should also specify the GVWR.
* Use the VIN: You can use the vehicle identification number (VIN) to look up the specifications online through sources like a Chevrolet dealer or a vehicle history report website.
