Engine restart without starter motor intervention
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
When the PCM detects engine restart parameters resulting from a driver action or system request, the PCM activates the fuel injection and ignition systems to allow the engine to continue to operate. This is available at a variable engine speed threshold which depends on engine type.
