Some customers may comment that the APO may turn off automatically without any indication to the driver. The driver will notice the APO LED turns off without a DIC message, during an Auto-Start.

This condition only occurs during the initial engine break-in period (engine hours less than 20) for engines that require higher than normal torque during an Auto-Start. Customers can restart the APO by depressing the APO button on the instrument panel.
