General Motors Tire Fill Alert Technology
Tire Fill Alert is a General Motors convenience technology that provides visual and audible alerts outside the vehicle when inflating an under-inflated tire to the recommended tire pressure. The technology is intended to help drivers determine how much air has been aded to the tire while inflating it.
Tire Fill Alert removes the need to use an air pressure gauge when filling up tires.
Tire Fill Alert made its debut in the all-new 2018 GMC Acadia. Most other GM vehicles were rolled out with the technology for the 2018, 2019 and 2020 model years.
