The ESN for your 2011 Ford Escape's Sirius satellite radio system – short for electronic serial number – works as a unique identifier, similar to your driver's license number or social security number. Before activating, transferring or canceling a Sirius subscription, you must obtain the 12-digit ESN. Activation and deactivation occurs when an orbiting Sirius satellite sends the appropriate one-way signal to your radio, based off the radio's specific ESN.
Start the vehicle's engine, or switch the ignition to the second or third position. Press the “VOL” button If the audio unit does not automatically power on.
Press the “SIRIUS” button. Hold the “AUX” and “1” preset button at the same time. Release the buttons and write down the ESN number displayed on the audio unit's screen.
Contact SiriusXM – either by Internet or telephone – to activate a new account, or make changes to an existing account.
