“I see that your vehicle has an open service campaign that we would like to take care of for you while you
are here today. This service campaign relates to the vehicle’s Battery Management System whereby the
vehicle may experience a condition that results in the instrument cluster displaying “EV Warning Light On.”
We will inspect your vehicle and either update the vehicle’s Battery Management System (BMS) software

inconvenience.”
