The chassis number is on the firewall under the hood on all models. All vehicles also have the chassis number (also known as the Vehicle Identification Number) on a plate attached to the top of the instrument panel on the driver's side, visible through the windshield. The chassis serial number is preceded by the model designation. All models have an Emission Control information label on the firewall or on the underside of the hood.
