4D Tech Start/Stop Eliminator: 19-24 Sierra 1500

19-24 Sierra 1500 Start/Stop Eliminator

The Auto Start/Stop system is simple. It automatically shuts off the engine when the vehicle is at rest (but not in park) to cut fuel use and eliminate idle emissions. It then restarts the engine automatically when the driver lifts off the brake to get going again.

The Start/Stop Eliminator is an revolutionary device that easily plugs in behind the start / stop switch - eliminating the need to press the button every time you turn the vehicle on!

Note: This is sometimes confused with the Auto Engine Idle Shutdown (AEIS) feature on many vehicles. The idle shutdown system shuts off a vehicle that is idling while parked after 30 minutes.
