Disabling auto start/stop on your Hyundai Santa Fe couldn't be easier. This intelligent device restores your preference for auto start-stop automatically which eliminates the need to press the disable ISG button after each ignition cycle.
The Autostop Eliminator device simply plugs in on the backside of the auto start/stop switch assembly on the Hyundai Santa Fe.
