## NHTSA's summary

Feature code 0008TSJ for auto start stop is a feature that will allow you to preset values in the body controller to allow the truck to start when the battery voltage or engine oil temperature reaches the preset value. The engine will then run for a preset time after battery voltage is within programmed value \(if the engine started for low voltage\) or the engine will run until oil temperature reaches a programmed value \(if the engine started for oil temperature\).
