What Is Engine Off Power Delay?
After the engine is turned off, some vehicles have an Engine Off Power Delay feature that keeps the radio and other electrical components powered for a short period of time.
If you don’t want to run the engine while listening to music or using other vehicle features, this can be helpful.
After the engine has been turned off, the system detects and activates a timer that delays the power-off signal for a set period of time.
As a result of this delay, the radio and other components will continue to receive power from the battery, so they can continue to function normally.
How Engine Off Power Delay Works?
When the Engine Off Power Delay feature turns on, some of the car’s electrical parts will keep working for a while after the engine shuts off. These parts include the switches for the power windows, the radio, the Uconnect phone system (if it’s installed), the DVD video system (if it’s installed), the power sunroof (if it’s installed), and the power plugs.
After the ignition turns off, the Engine Off Power Delay function powers these components for 10 minutes. It’s worth noting that if you open a front door, the feature will be off immediately to prevent unnecessary power consumption.
The length of the Engine Off Power Delay can be changed if someone wants to make it fit their needs better. To do this, go to the settings menu and use the “+” and “-” buttons to move through the choices. Users can choose from “0 seconds,” “45 seconds,” “5 minutes,” or “10 minutes.” A longer delay time extends functioning when the engine is shut off, whereas a lower delay time conserves battery life.
